Description

Technical Field

[0001] The present disclosure relates to an insect monitoring device.

Background Art

[0002] Generally, for crops and the like, information regarding the number of pests (appearance number), i.e., where, when, what kind of pests are present, and how many, is fundamental information for pest control and understanding their ecology. If such information is obtained, it is possible to understand the behavior ecology of pests and determine the appropriate timing for control, and this information can also be utilized for decision-making on issuing warning information regarding pests.

[0003] For example, crop damage caused by a large outbreak of the beet leafhopper has become a global problem. In Japan as well, a large outbreak of the brown planthopper has caused significant damage to rice cultivation. In particular, due to recent climate change and the like, the occurrence of new migratory pests such as the beet armyworm is also regarded as a problem. Therefore, accurately monitoring the occurrence of these pests and leading to appropriate control is an important technical issue in agricultural technology.

[0004] As a method for monitoring pests, for example, there is a method in which after attracting pests using a trap or the like that utilizes an attractant such as a sex pheromone agent that has the effect of specifically attracting males of a specific pest or a chemical substance with the smell of bait, and then killing and measuring the number of captured pests. Various insect monitoring devices for monitoring pests using these traps have been proposed.

[0005] The applicant has proposed a pest monitoring device comprising: a pest trapping unit having a partitioned space for trapping and killing pests, an attracting means for attracting pests into the trapping space, and an insecticide for killing pests attracted by the attracting means; a pest photography unit having a partitioned space for photographing pests trapped in the pest trapping unit; and a photography means for photographing pests present in the photography space of the pest photography unit (Patent Document 1). In this pest monitoring device, the trapping space and the photography space are separated within the device so that trapped pests can move from the trapping space to the photography space, resulting in a simple structure, excellent maintainability, and the ability to maintain the accuracy of pest monitoring. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2022-127613 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] By the way, the types and quantities of pests present at the survey site vary depending on weather conditions and the pest situation in adjacent farms. Therefore, it is necessary to conduct surveys of different types of pests depending on the season and environmental conditions. If the types of pests being monitored are different, it is necessary to switch to a different attractant.

[0008] However, conventional devices have a structure where one attractant is placed inside the insect trapping unit (the container or trap that makes it up), which is inconvenient because it requires the user to go to the site and manually place and replace the attractant. Also, since the components of the attractant are heavier than air, volatile components (particles) from the attractant adhere to the inside of the container or trap. Therefore, when replacing the attractant using the same container or trap, the replaced attractant may mix with the original attractant and become contaminated. It is known that the attracting effect of the attractant decreases due to contamination. Therefore, with conventional devices, for example, it is necessary to clean the container or trap that holds the original attractant before replacing the attractant, or to prepare a separate container or trap for each attractant and replace the whole thing, which is time-consuming and costly. Thus, there is room for improvement in the device in terms of making it possible to easily replace the attractant.

[0009] Furthermore, when handling multiple attractants in a single device, it is necessary to configure the device so that the attractants do not mix within the device in order to suppress the decrease in the attractiveness of each attractant. In this respect as well, there is room for improvement in the device.

[0010] This disclosure has been made in view of the above, and its purpose is to provide an insect monitoring device equipped with multiple attractants that can maintain their attractiveness by suppressing contamination of each attractant, and that can replace attractants without going to the site. [Means for solving the problem]

[0011] To achieve the above objectives, this disclosed technology is designed to handle multiple attractants in a single device and to allow for automatic replacement. To this end, a storage means is applied that can separate and store each attractant, and also allow it to be opened to the outside of the device or closed. As a result of diligent research, the inventors have completed the device of this disclosure that accommodates multiple attractants by further incorporating a control mechanism that controls the opening and closing of the storage means.

[0012] (1) Specifically, this disclosure relates to a monitoring device for monitoring insects. The insect monitoring device is • A first space for attracting insects is partitioned, and multiple attractants for attracting insects are placed within the first space. A storage means having a plurality of storage spaces for storing each of the plurality of attractants separately, and at least one opening / closing mechanism for opening or closing each of the plurality of storage spaces to the outside of the device, A control mechanism that controls the opening and closing of at least one of the opening and closing mechanisms, • Insect treatment means for killing or immobilizing insects attracted by each of the aforementioned attractants, The system includes a counting means for counting insects whose movement has been stopped by the insect processing means, The control mechanism is characterized by releasing only one of the multiple attractants outside the device by opening one of the multiple storage spaces while closing all the other storage spaces.

[0013] The insect monitoring device of this disclosure includes a storage means having multiple storage spaces for storing multiple attractants separately, so that multiple attractants can be handled in a single device, and contamination of each attractant can be suppressed, maintaining their attractiveness. Furthermore, the insect monitoring device includes a storage means having at least one opening / closing mechanism for opening or closing each of the multiple storage spaces to the outside of the device, and a control mechanism for controlling the opening and closing of the opening / closing mechanism, so that by operating the control mechanism, an attractant can be automatically replaced with another.Therefore, the insect monitoring device of this disclosure can accommodate multiple attractants, suppress contamination of each attractant, maintain their attractiveness, and replace them with another attractant without going to the site.

[0014] (2) The first space is partitioned into one section, and the storage means is configured to be attachable to the device, and within the one storage means, there may be multiple sections of the storage space connected to the one first space. In this configuration, multiple storage spaces are partitioned inside a single storage means located outside the device (first space), and only one first space for attracting insects is partitioned, so the structure of the device is simple.

[0015] (3) The first space may be divided into multiple sections according to the multiple attractants, and the multiple storage spaces may be composed of the multiple first spaces. In this configuration, each storage space and each first space are configured in common, and no attachments are required, so although the device itself becomes larger, the structure of the device is simple.

[0016] (4) The first space is partitioned into one section, and the storage means are configured in multiple ways according to the multiple attractants so as to be attachable to the device, and each of the storage means may partition into one storage space connected to the one first space. In this configuration, multiple storage means can be arranged outside the device (first space) according to the type of attractant, and since there is only one storage space partitioned inside the storage means, the structure of the storage means and the device is simple. [Effects of the Invention]

[0017] As described above, this disclosure provides an insect monitoring device that includes multiple attractants, can maintain its attractive effect by suppressing contamination of each attractant, and can replace attractants without having to go to the site. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0019] Hereinafter, the present embodiment will be described in detail based on the drawings. The following description of the preferred embodiment is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses in any way.

[0020] (First Embodiment) <Insect Monitoring Device> FIGS. 1 to 3 show an insect monitoring device A1 according to the first embodiment. The insect monitoring device A1 is a device for monitoring insects. The insects to be monitored include pests and useful insects. Examples of pests include pests of Lepidoptera (such as moths), Hemiptera (such as stink bugs and aphids), Coleoptera (such as ladybugs and click beetles), Thysanoptera, Diptera (such as flies), and Orthoptera (such as grasshoppers). Examples of useful insects include bees, spiders, some Lepidoptera (such as moths), and Hemiptera (such as stink bugs and aphids).

[0021] As shown in FIG. 1, the insect monitoring device A1 is fixedly attached to the installation base 1 and is installed at an arbitrary survey site by burying one end of the installation pole 2 provided on the installation base 1. When monitoring the larvae of insects, since the larvae have the habit of hiding on the ground surface during the day and have no flying ability, the insect monitoring device A1 may be installed above the ground.

[0022] The insect monitoring device A1 has a first space S1 partitioned off to attract insects. The first space S1 is formed inside a container-shaped device body 11 with a bottom and lid. The shape of the device body 11 is not particularly limited and can be a box (square, rectangular), cylindrical (circular), etc. The size of the device body 11 should be such that it has a first space S1 large enough to hold insects for a predetermined period (for example, every day). The device body 11 may be made using commercially available resin plates or resin containers. As for the resin material that constitutes the device body 11, from the viewpoint of being able to easily visually confirm the insects, colorless transparent or colored transparent resin materials such as acrylic or polycarbonate can be used. On the other hand, since seeing insects can cause discomfort, the resin material may be semi-transparent to make it difficult to see inside the device body 11, or it may be an opaque (for example, white) resin material to make it impossible to see inside the device body 11.

[0023] An opening / closing mechanism 14 is provided on the bottom surface of the main body 11 of the device. In other words, the insect monitoring device A1 may be equipped with an opening / closing mechanism 14. The opening / closing mechanism 14 is designed to be openable and closable and to allow the counted insects to move (pass through) from the main body 11 (first space S1) to the outside of the device. Therefore, the opening / closing mechanism 14 can be considered a disposal mechanism for discarding the counted insects. The opening / closing mechanism 14 has a plurality of opening / closing plates 15 (three in Figure 1), a rotating shaft 16 provided on each opening / closing plate 15, and a driving mechanism 17 for driving the rotating shaft 16. The driving mechanism 17 causes each opening / closing plate 15 to rotate around each rotating shaft 16 in conjunction, so that the bottom surface of the main body 11 can be automatically opened and closed. That is, the bottom surface of the main body 11 (opening / closing mechanism 14) has an automatic opening / closing shutter structure. The drive mechanism 17 is not particularly limited and can include, for example, a motor, an actuator, or an automatic opening and closing device that can lock and unlock the door in conjunction with a smartphone, and commercially available devices can be used. Insects discarded outside the device may be left to fall directly onto the ground below the device, or a box or similar container may be placed below the device to collect the fallen insects.

[0024] As shown in Figure 1, the insect monitoring device A1 comprises multiple attractants 12, a storage means 30a, a control mechanism C (see Figures 2 and 3), an insect processing means 13, and a counting means 40. The insect monitoring device A1 handles multiple attractants 12 with a single device. The multiple attractants 12 may be of different types or of the same type.

[0025] (Attractant) The attractant 12 is a volatile attractant 12 that attracts insects into the first space S1 by releasing volatile components. Examples of attractants 12 include sex pheromones that specifically attract males of a particular insect species, and chemical substances that smell like bait. These attractants 12 may be used individually (of the same species) or in combination.

[0026] (Storage means) The storage means 30a is a means for storing and opening / closing multiple attractants 12 separately. As shown in Figure 1, the insect monitoring device A1 is equipped with one storage means 30a. The storage means 30a is configured to be attachable to the device (such as the attachment 19 or column 20, which will be described later). The storage means 30a is provided, for example, on the upper part of the attachment 19. As shown in Figure 2, the attachment 19 is provided to cover, for example, an opening (not shown) formed on the upper outer surface of the device body 11, and is connected to the first space S1. The attachment 19 is configured to prevent insects (e.g., insects P) captured in the first space S1 from escaping.

[0027] The storage means 30a is positioned with a gap between the upper part of the attachment 19 and the lower part of the storage means 30a, via a plurality of (four in Figures 2 and 3) columnar sections 20 located on the upper part of the attachment 19, allowing insects P to pass through. Attracted insects P enter the device through this gap and move into the first space S1 through the attachment 19. Note that if the device has a structure in which a gap is formed at the lower part of the storage means 30a (the part where the attractant 12 is released outside the device) that allows insects P to pass through, the attachment 19 does not need to be provided.

[0028] The storage means 30a includes a storage section 31a and a single opening / closing mechanism 33 (see Figures 2 and 3).

[0029] The storage section 31a is a part that stores multiple attractants 12. The method of storing the attractants 12 in the storage section 31a is not particularly limited and includes methods such as fixing them to the inner surface of the storage section 31a or suspending them from the top of the storage section 31a.

[0030] The storage section 31a is formed, for example, as a structure in which a cylindrical upper storage section 31a(t) and a frustoconical lower storage section 31a(b) are connected. The upper storage section 31a(t) is formed as a container with a bottomless lid, with the top surface (top surface) closed and the bottom surface open. The lower storage section 31a(b) is formed as a container with a bottomless lid, with both the top and bottom surfaces (bottom surfaces) open. However, the shape of the storage section 31a is not limited to the above.

[0031] As shown in Figure 2, the storage section 31a is partitioned into multiple (four in Figure 2) storage spaces S12 (S12a to S12d) for each of the multiple (four in Figure 2) attractants 12 (12a to 12d) to be stored separately. For example, storage spaces S12a and S12b are physically separated by a partition plate 34ab. Storage spaces S12b and S12c are physically separated by a partition plate 34bc. Storage spaces S12c and S12d are physically separated by a partition plate 34cd. Storage spaces S12d and S12a are physically separated by a partition plate 34da. Adjacent storage spaces S12 are blocked off by partition plates 34ab, 34bc, 34cd, and 34da. In the insect monitoring device A1, each attractant 12 is stored individually in its respective storage space S12, thus preventing the mixing (contamination) of each attractant 12 within the storage means 30a (its storage section 31a).

[0032] The opening / closing mechanism 33 is a mechanism that opens or closes each of the multiple storage spaces S12 to the outside of the device. As shown in Figure 2, the opening / closing mechanism 33 opens one of the four storage spaces S12a to S12d (S12a in Figure 2) while closing all other storage spaces S12b to S12d. For example, the opening / closing mechanism 33 is formed from a fan-shaped flat plate (opening / closing plate) with a notch cut out of a disc (with a central angle of 270° in Figure 2) so that only one of the storage spaces S12 can be opened. The opening / closing mechanism 33 is configured to be rotatable with the vertical direction (up and down direction in Figure 2) as the axis of rotation.

[0033] Furthermore, the opening and closing mechanism 33 is positioned to further divide the storage section 31a (storage space S12) into two upper and lower sections, the upper storage section 31a(t) and the lower storage section 31a(b). A mesh-like partition plate 35 is provided on the entire surface (common to all; see also Figure 3) of the lower surface of the opening and closing mechanism 33, allowing the volatile particles (P12a to P12d) of each attractant 12a to 12d to pass through. The partition plate 35 may be fixed to the storage section 31a. Through the opening and closing mechanism 33 and the partition plate 35, the storage spaces S12a to S12d are divided into the lower storage space S12a(b) to S12d(b) and the upper storage space S12a(t) to S12d(t), respectively. Attractants 12a to 12d are placed in the upper storage spaces S12a(t) to S12d(t), which are partitioned within the upper storage section 31a(t).

[0034] Then, as the opening / closing mechanism 33 (opening / closing plate) rotates on the partition plate 35, in the areas where the opening / closing plate is not positioned (where the opening / closing mechanism 33 is open), the lower storage space S12a(b) and the upper storage space S12a(t) are connected, and the storage space S12a is opened to the outside of the device. As a result, the volatile particles P12a of the attractant 12a stored in the upper storage space S12a(t) pass through the partition plate 35, go further down through the lower storage space S12a(b), and scatter to the outside of the device through the gap between the lower storage section 31a(b) (storage means 30a) and the attachment 19. On the other hand, in the areas where the opening / closing plate is positioned (where the opening / closing mechanism 33 is closed), the lower storage spaces S12b(b) to S12d(b) and the upper storage spaces S12b(t) to S12d(t) are separated, and all storage spaces S12b to S12d are closed. Therefore, the volatile particles P12b to P12d of the attractants 12b to 12d stored in the upper storage spaces S12b(t) to S12d(t), respectively, cannot pass through the partition plate 35 and remain within the upper storage spaces S12b(t) to S12d(t). In this way, by opening and closing the opening and closing mechanism 33, only the attractant 12a stored in storage space S12a is released (exposed) outside the device.

[0035] Modified storage method The storage means 30a is not limited to the structure described above, as it has the function of storing and opening / closing multiple attractants 12 separately. The number of storage spaces S12 partitioned within one storage section 31a can be appropriately determined according to the type and number of attractants 12. The shape and arrangement of the opening / closing mechanism 33 can be appropriately determined according to the shape of the storage means 30a and the shape and number of storage spaces S12. If the opening / closing mechanism 33 is made of a flat rotating plate, it may be shaped such that a hole is formed in at least a part of the rotating plate so that only one of the storage spaces S12 can be opened. Alternatively, as shown in Figure 3, the storage means 30b may have a storage section 31b on which the opening / closing mechanism 33 (and partition plate 35) is located on the bottom surface. The storage section 31b is formed, for example, in the shape of a frustoconical container with a bottomless lid, with the top surface closed and the bottom surface open. The shape of the storage section 31b is not limited to the above. In the storage section 31b, the attractants 12a to 12d are placed in storage spaces S12a to S12d, which are partitioned by partition plates 34ab, 34bc, 34cd, and 34da, respectively. In the storage means 30b, the volatile particles P12a to P12d of each attractant 12a to 12d are released (exposed) outside the device from the opened storage space S12a, depending on whether the opening / closing mechanism 33 is present or not.

[0036] (Control mechanism) Control mechanism C is a mechanism that controls the opening and closing of the storage means 30a and its modified form 30b (the opening and closing mechanism 33 that constitutes it). As shown in Figures 2 and 3, control mechanism C controls the operation (rotation) of the opening and closing mechanism 33. Control mechanism C can be described as a mechanism that selects one attractant 12 (12a in Figures 2 and 3) from among a plurality of attractants 12 and controls the release of the selected attractant 12a. With control mechanism C, the attractant 12 can be changed for each insect being monitored without having to go to the site. Note that control mechanism C is not particularly limited as long as it is capable of operating (rotating) the opening and closing mechanism 33, and examples of commonly available drive means such as motors, actuators, and belt conveyors can be cited.

[0037] (Methods for dealing with insects) The insect treatment means 13 is a means of killing or immobilizing insects attracted to the first space S1 by the attractant 12. Immobilizing insects means, for example, making them motionless, inactive (not active), or in a state of suspended animation. In other words, the insect treatment means 13 is a means of stopping the movement of insects. The insect treatment means 13 may be used individually or in combination with the following:

[0038] Conventional insecticides can be used as a means of killing insects. Among insecticides, resin-type vaporizing insecticides (insecticide plates) can be suitably used. Examples of insecticides include commercially available pesticides (chemical pesticides such as liquid and resin types); and, in consideration of environmental issues and SDGs (Sustainable Development Goals), plant-derived substances containing insecticidal components (plant essential oils using terpenes, pyrethrum extract, etc.) as alternatives to chemical pesticides. Furthermore, the insecticide should be arranged so that it can vaporize throughout the entire first space S1 within the main body of the device 11, and as shown by reference numeral 13 in Figure 1, it is installed, for example, approximately in the middle of one inner surface of the main body of the device 11.

[0039] Means of immobilizing insects include, for example, a temperature control mechanism (not shown) that controls the temperature inside the device (first space S1). Examples of temperature control mechanisms include surface heaters such as PTC heaters, Peltier elements, electric fans (hot air fans), and air conditioning devices (air conditioners). Generally, commercially available temperature control mechanisms can be used. By using means to immobilize insects, they can be counted alive without being killed, making it possible to monitor not only pests but also beneficial insects for biodiversity and conservation.

[0040] (Counting means) The counting means 40 is a means for counting insects whose movement has been stopped by the insect processing means 13. The counting means 40 can be the photographing device 40a, weight sensor 40b, passage sensor 40c (see Figure 5), etc., as shown in Figure 1. These counting means 40 may be used individually or in combination. As shown in Figure 1, it is preferable that the counting means 40 be placed outside the main body of the device 11 (first space S1) (outside the device) from the viewpoint of suppressing counting errors caused by insect contaminants.

[0041] As shown in Figure 1, the imaging device 40a is positioned, for example, on the upper outer surface of the main body of the device 11 (above the first space S1). The imaging device 40a photographs insects that have been immobilized by the insect processing means 13 and counts the insects from the captured images. The imaging device 40a is not particularly limited, and commercially available digital cameras or mobile phones (smartphones) can be used. The imaging device 40a allows for highly accurate monitoring not only of the number of insects caught, but also of their shape and size.

[0042] The weight sensor 40b (see Figure 1) and the passage sensor 40c (see Figure 5) are, for example, positioned on the outside of the bottom surface of the main body of the device 11 (below the first space S1). When using the weight sensor 40b, for example, the difference between the weight of the main body of the device 11 after a predetermined monitoring period and the initial weight of the main body of the device 11 is calculated, and the insects are counted from the calculated result (insect weight). When using the passage sensor 40c, for example, the insects are counted when they are released outside the device from the opening / closing means 14 (its opening / closing plate 15) that constitutes the bottom surface of the main body of the device 11. Generally, commercially available weight sensors 40b and passage sensors 40c can be used.

[0043] [Other configurations] In addition to the means and mechanisms described above, the insect monitoring device A1 may further include the following means as needed.

[0044] (Means of communication) The insect monitoring device A1 may also be equipped with an antenna 41 (see Figure 5) as a communication means for wirelessly transmitting numerical data counted by the counting means 40 and images of insects that have been captured. This eliminates the need for researchers to physically visit the survey site over long periods of time.

[0045] (Control means) The insect monitoring device A1 may be equipped with control means (not shown) for managing and controlling the control mechanism C, counting means 40, opening / closing means 14, disposal means, etc., as a whole. The control means is not particularly limited, and commercially available electronic devices such as mobile phones (smartphones), tablet terminals, and personal computers can be used. One electronic device may be provided as the control means, the camera 40a, and the antenna 41, or multiple electronic devices may be provided individually. Furthermore, various systems such as image processing software and individual identification software may be introduced into the electronic device to further provide an automatic insect counting (identification) function. Since the camera 40a can capture images of undamaged insects, the number of captured insects can be visually counted from the captured images, but erroneous counting is less likely to occur when using this system for automatic counting.

[0046] <Operation Flowchart of Insect Monitoring Device> The operation flow of the insect monitoring device A1 shown in Figures 1 and 2 is described below. In the following example, one attractant 12a is selected from among multiple attractants 12 stored in the storage means 30a according to the insect P. In this case, first, the opening / closing mechanism 33 is activated (rotated) by the control mechanism C, and storage space S12a, which stores the attractant 12a, is opened from among the four storage spaces S12a to S12d partitioned within a single storage unit 31a. At this time, storage spaces S12b to S12d other than storage space S12a are closed by the opening / closing mechanism 33. Next, the insect P is attracted by one type of attractant 12a scattered from the opened storage space S12a, and the insect P is captured in the first space S1 via the attachment 19. The captured insect P is killed or immobilized by the insect processing means 13 in the first space S1. Finally, the insect P that is lying motionless on the bottom surface of the device body 11 is counted by the counting means 40. For example, counting data is transmitted to a server via wireless communication using the antenna 41 and stored there. After counting, the automatic opening and closing shutter (opening / closing means 14) located on the bottom of the main body 11 of the device is opened as needed, at a predetermined time (for example, during a time when the activity of insects P decreases) or at predetermined intervals (for example, every day). When this happens, the insects P pass through the automatic opening and closing shutter with the opening / closing plate 15 in the open state and are discarded (fall) out of the device from the first space S1. Alternatively, the automatic opening and closing shutter may be closed after the insects P have passed through, closing the opening / closing plate 15. Through this series of operations, the insect monitoring device A1 returns to its state before monitoring started (initial state).

[0047] Next, we will explain the operation flow of the insect monitoring device A1 when changing the monitoring target from insect P to a different type of insect Q. In this example, one attractant 12b is selected according to insect Q. The control mechanism C operates (rotates) the opening / closing mechanism 33, opening the storage space S12b that stores the attractant 12b. At this time, storage spaces S12a, S12c, and S12d other than storage space S12b are closed by the opening / closing mechanism 33. In this way, by operating the control mechanism C, the storage space S12 that is opened can be changed, and the attractant 12 released (exposed) outside the device can be replaced. Furthermore, since the storage spaces S12a to S12d are physically separated, the attractant 12b within the storage section 31a (storage means 30a) is less likely to be contaminated with the other attractants 12a, 12c, and 12d, and the attractant effect is easily maintained. As a result, insect Q is attracted by a type of attractant 12b scattered from the released storage space S12b, and can be captured in the first space S1 via the attachment 19. The subsequent flow is as described above.

[0048] <Applications of insect monitoring devices> The following applications (uses) are envisioned for the insect monitoring device A1 according to this embodiment. For research purposes, for example, it can be used to elucidate the detailed migration routes of migratory pests and the mechanisms of their mass outbreaks; it can be used to understand the ecology of migratory pests and predict their outbreaks. Furthermore, for social applications, for example, it can be used to monitor and predict the outbreaks of pests on field crops, vegetables, fruit trees, flowers, and trees; to control and monitor pests that transmit infectious diseases; to use as a basic technology in plant quarantine; to support decision-making regarding pesticide application based on pest outbreak data (smart agriculture technology); and to predict pest outbreaks using high-resolution outbreak data. Regarding the pest outbreak prediction method and pest outbreak prediction system, the method and system proposed by the applicant in Patent Document 1 can be applied.

[0049] <Effects> As described above, the insect monitoring device A1 according to this embodiment provides the following benefits. The insect monitoring device A1 has a first space S1 partitioned by the main body 11 of the device, and is equipped with multiple attractants 12, a storage means 30a, a control mechanism C, an insect processing means 13, and a counting means 40, so that multiple attractants 12 can be handled by a single device. The insect monitoring device A1 is equipped with a single storage means 30a for storing multiple attractants 12, and multiple attractants 12 are stored separately in multiple storage spaces S12 partitioned within the storage section 31a that constitutes the storage means 30a. As a result, in the insect monitoring device A1, each attractant 12 is less likely to mix within the storage means 30a, thus preventing contamination and maintaining the attractant effect. In addition, the insect monitoring device A1 reduces the effort required for maintenance such as cleaning the storage means 30a. The insect monitoring device A1 includes a control mechanism C that controls the operation (opening and closing) of a single opening / closing mechanism 33 that individually opens or closes a plurality of storage spaces S12, which constitute the storage means 30a, to the outside of the device. The control mechanism C opens one of the multiple storage spaces S12 (S12a) while closing all the other storage spaces (S12b to S12d), thereby releasing only one attractant (12a) from among the multiple attractants 12 to the outside of the device. As a result, the insect monitoring device A1 can be automatically replaced with another attractant 12 by operating the control mechanism C. Based on the above, the insect monitoring device A1 is configured to attract insects into a single first space S1, process the insects within the first space S1, and count them. Furthermore, the insect monitoring device A1 is configured to store multiple attractants 12 separately in a single storage means 30a, and to control the opening and closing of the storage section 31a (and its opening / closing mechanism 33) with a single control mechanism C. Therefore, the structure of the device can be made simple, and the overall cost of the device can be reduced. The insect monitoring device A1 allows for the replacement of the attractant 12 without having to go to the site, either every other day, at the end of the monitoring period, or according to certain conditions (e.g., weather conditions). Therefore, by utilizing the insect monitoring device A1 series, the labor involved in forecasting the occurrence of multiple insect species can be reduced, and detailed insect occurrence information can be obtained at individual locations.

[0050] (Second embodiment) <Insect monitoring device> Figure 4 shows an insect monitoring device A2 according to the second embodiment. The insect monitoring device A2 differs in structure from the insect monitoring device A1 according to the first embodiment in that multiple first spaces S1 for attracting each insect are partitioned. Except for the matters described in detail below, the configuration is the same as that of the first embodiment, so a detailed explanation is omitted here. Also, the same reference numerals are used for components that are the same as in the first embodiment, and their explanations are omitted. The configuration described in the first embodiment can also be used in the insect monitoring device A2.

[0051] As shown in Figure 4, the insect monitoring device A2 is divided into multiple (three in Figure 4) first spaces S1 (S1a to S1c) according to multiple (three in Figure 4) attractants 12 (12a to 12c) . Each first space S1 is physically separated. The multiple first spaces S1 constitute multiple storage spaces S12. The insect monitoring device A2 is equipped with multiple (three in Figure 4) storage means 30c (30ca to 30cc) that divide the multiple storage spaces S12, instead of the storage means 30a and its modified form 30b that constitute the insect monitoring device A1.

[0052] (Storage means) The insect monitoring device A2 has multiple (three in Figure 4) storage sections 36 (36a to 36c) that constitute storage means 30ca to 30cc according to multiple (three in Figure 4) attractants 12a to 12c, and multiple (three in Figure 4) opening and closing mechanisms 37 (37a to 37c).

[0053] Storage sections 36a to 36c are parts for detachably storing the attractants 12a to 12c, respectively. Within each of the storage sections 36a to 36c, there are multiple (three in Figure 4) storage spaces S12 (S12a to S12c). The storage sections 36a to 36c and the storage spaces S12a to S12c are individually provided in the main body 11 of the device and are physically separated. The storage spaces S12a to S12c and the first spaces S1a to S1c are common to each other. In other words, the storage spaces S12a to S12c are each composed of the first spaces S1a to S1c.

[0054] Within each of the storage spaces S12a to S12c (and the storage compartments 36a to 36c that partition them), one of the attractants 12 is stored separately. For example, in the first space S1a, which is shared with storage space S12a, an insect P attracted by attractant 12a is captured, and in the first space S1b, which is shared with storage space S12b, an insect Q attracted by attractant 12b is captured.

[0055] Each of the opening and closing mechanisms 37a to 37c is formed by an opening on the upper side of the storage section 36a to 36c that connects to the first space S1 (storage space S12). Each of the opening and closing mechanisms 37a to 37c can be opened and closed individually.

[0056] Modified storage method The multiple storage compartments 36 configured as storage means 30c only need to have the function of being able to store and open / close multiple attractants 12 separately, and are not limited to the structure described above. As a variation of the opening / closing mechanism 37 that constitutes the storage compartment 36, for example, an automatic opening / closing shutter structure similar to the opening / closing means 14 described above may be provided on the upper surface of the storage compartment 36. In addition, the height positions of each storage compartment 36 and opening / closing mechanism 37 may be different, and they may have a moving mechanism that can change their position in the height direction. For example, since the attractant 12 is heavier than air, by placing the storage compartment 36 or opening / closing mechanism 37 of the attractant 12 that is not being used lower down or moving it, contamination of other attractants 12 can be further suppressed.

[0057] (Control mechanism) Control mechanism C is a mechanism that controls the operation (opening and closing) of multiple opening and closing mechanisms 37a to 37c that constitute the storage means 30c in a unified manner. In the insect monitoring device A2, control mechanism C controls the opening and closing of opening and closing mechanisms 37a to 37c individually. As shown in Figure 4, control mechanism C opens only one of the opening and closing mechanisms 37 (37a in Figure 4) to open the storage space S12a (first space S1a), while closing the other opening and closing mechanisms (37b, 37c in Figure 4) to close all of the storage spaces S12b, S12c (first spaces S1b, S1c). Note that since the insect monitoring device A2 controls the operation of multiple opening and closing mechanisms 37a to 37c both in a unified manner and individually, it is sufficient to have only one control mechanism C.

[0058] [Other configurations] The insect monitoring device A2 has multiple spaces with different purposes partitioned within the main body 11, including three first spaces S1a to S1c partitioned by three storage compartments 36 (36a to 36c), and one common second space S2. In the insect monitoring device A2, each of the first spaces S1a to S1c is located above and adjacent to the second space S2 (each of its sides, the left and right sides and the rear side in Figure 4), arranged in a stepped pattern when viewed from the front. Each of the first spaces S1 (storage compartment 36) is provided with one attractant 12 and one insect processing means 13.

[0059] The insect monitoring device A2 may be equipped with a disposal means 23 at the bottom of the second space S2 for discarding the insects after counting. The disposal means 23, like the opening and closing means 14 described above, is openable and closable and allows the counted insects to move (pass through) from each first space S1 to the outside of the device, and employs an automatic opening and closing shutter structure. Specifically, the disposal means 23 has a plurality of opening and closing plates 27 (three in Figure 1), a rotating shaft 28 provided on each opening and closing plate 27, and a driving means 29 for driving the rotating shaft 28. The driving means 29 causes each opening and closing plate 27 to rotate around each rotating shaft 28 in conjunction, so that the bottom of the device can be opened and closed automatically. The driving means 29 is not particularly limited and can be the same as that exemplified in the driving means 17 described above.

[0060] The second space S2 may be further divided into two spaces. In other words, another space may be provided above the second space S2. For example, the upper surface of the second space S2 may be a common partition plate 24, and the second space S2 and the third space S3 may be adjacent to each other, arranged in a two-tiered structure in a single row vertically (up and down) when viewed from the front. The third space S3 is, for example, a storage space for housing the imaging device 40a (counting means 40). A lid member 25 that can be opened and closed is provided above the third space S3. The lid member 25 facilitates the retrieval and maintenance of the imaging device 40a.

[0061] The insect monitoring device A2 is equipped with three connecting parts 45 (45a to 45c) that connect two spaces to each other between three first spaces S1a to S1c and a common second space S2. Three connecting spaces S4 (S4a to S4c) are partitioned through each connecting part 45, connecting each of the first spaces S1a to S1c and the common second space S2. Each connecting part 45a to 45c is provided with a common opening / closing mechanism 14 (14a to 14c) that connects the connecting space S4 and the first space S1, and an opening 8 (8a to 8c) that connects the connecting space S4 and the second space S2 is formed. In addition, each connecting part 45 has a sloping surface 46 (46a to 46c) on its side, which is partitioned by the lower edge of each opening 8a to 8c and one side on the opening / closing mechanism 14 side that is parallel to the lower edge. In this way, the processed insects move into their respective first spaces S1a to S1c, their respective connecting spaces S4a to S4c, and the common second space S2 via their respective opening and closing means 14a to 14c, slopes 46a to 46c, and openings 8a to 8c.

[0062] The insect monitoring device A2, configured as described above, is divided into multiple first spaces S1 according to the type and number of attractants 12, and includes multiple storage means 30c and multiple insect processing means 13, as well as a common control mechanism C and a counting means 40. In the insect monitoring device A2, the first space S1 is a space for attracting and processing insects, and the second space S2 is a counting space for counting the insects after processing. The connecting space S4 can be described as a movement space for moving insects from the first space S1 to the second space S2.

[0063] The insect monitoring device A2 (and its operation flow) shown in Figure 4 may be configured as follows, for example. In the following example, one attractant 12a is selected from among multiple attractants 12a to 12c stored in multiple storage sections 36a to 36c, which are configured as storage means 30ca to 30cc, according to the insect P. In this case, first, the control mechanism C operates only the opening / closing mechanism 37a (opens), opening only the storage space S12a (first space S1a) where the attractants 12a partitioned within the storage section 36a are stored. At this time, the opening / closing mechanisms 37b and 37c other than the opening / closing mechanism 37a are not operated (closed), and the storage spaces S12b and S12c (first spaces S1b and S1c) other than the storage space S12a are closed. Subsequently, the insect P is attracted by a type of attractant 12a scattered from the opened storage space S12a, and the insect P is captured in the first space S1a through the opening of the opening / closing mechanism 37a. The captured insects P are killed or immobilized by the insect treatment means 13 in the first space S1a. Then, at a predetermined time (for example, a time when the activity of insects P decreases) or at predetermined intervals (for example, every day), the opening / closing means 14a is automatically opened and closed, and the treated insects P are moved from the first space S1a to the second space S2 using the slope 46a. After that, the insects P are counted in the second space S2 by the imaging device 40a (counting means 40). Furthermore, the disposal means 23 is automatically opened and closed, and the counted insects P are automatically disposed of. Through this series of operations, the insect monitoring device A2 returns to the state before monitoring started (initial state).

[0064] Next, we will explain the operation flow of the insect monitoring device A2 when changing the monitoring target from insect P to a different type of insect Q. In this example, one attractant 12b is selected according to insect Q. The control mechanism C is used to activate (open) only the opening / closing mechanism 37b, and to deactivate (close) the opening / closing mechanisms 37a and 37c. In this way, by operating the control mechanism C, the storage space S12 that is opened can be swapped, and the attractant 12 released (exposed) outside the device can be changed. Furthermore, since the storage spaces S12a to S12c (common with the first space S1a to S1c) are physically separated, the attractant 12b is less likely to be contaminated with other attractants 12a and 12c within the device (storage section 36a to 36c), and the attractant effect is easily maintained. As a result, insect Q can be attracted by one type of attractant 12b scattered from the opened storage space S12b, and insect Q can be captured in the first space S1b through the opening of the opening / closing mechanism 37b. The subsequent flow is as described above.

[0065] <Effects> As described above, the insect monitoring device A2 according to this embodiment provides the same effects as the insect monitoring device A1 of the first embodiment described above. The insect monitoring device A2 is configured such that multiple first spaces S1 are partitioned according to multiple attractants 12, and multiple storage spaces S12 are formed by multiple first spaces S1. Therefore, the insect monitoring device A2 is configured to attract, process, and count insects using one attractant stored in each first space S1 (storage space S12). Furthermore, the insect monitoring device A2 is configured so that a single control mechanism C controls the operation (opening and closing) of multiple opening and closing mechanisms 37 that individually open and close multiple storage spaces S12. In addition, the insect monitoring device A2 does not require a separate storage means outside the device (for example, the storage means 30a shown in Figure 1). As described above, the insect monitoring device A2 also has a simple (simple) structure.

[0066] (Third embodiment) <Insect monitoring device> Figure 5 shows an insect monitoring device A3 according to the third embodiment. The insect monitoring device A3 differs in structure from the insect monitoring device A1 according to the first embodiment and the insect monitoring device A2 according to the second embodiment in that it has multiple storage means 30d that each store a plurality of attractants 12 separately and that can be opened and closed. Except for the matters described in detail below, the configuration is the same as that of the first and second embodiments, so a detailed explanation is omitted here. Also, the same reference numerals are used for components that are the same as those in the first and second embodiments, and their explanations are omitted. The configurations described in the first and second embodiments can also be used in the insect monitoring device A3.

[0067] As shown in Figure 5, the insect monitoring device A3, like the insect monitoring device A1, has a container-shaped main body 11 with a bottom and lid, within which a first space S1 for attracting insects is partitioned.

[0068] (Storage means) The insect monitoring device A3 is equipped with multiple (two in Figure 5) storage means 30da, 30db in response to multiple (two in Figure 5) attractants 12a, 12b. The storage means 30da, 30db are individually provided and physically separated.

[0069] Each of the storage means 30da and 30db has a storage section 31c (31ca, 31cb), a lid section 32 (32a, 32b), and an opening / closing mechanism 38 (38a, 38b), respectively. In other words, the insect monitoring device A3 has the same number of storage sections 31c, lid sections 32, and opening / closing mechanisms 38 as the number of storage means 30d. Herein, the storage means 30d differs from the storage means 30a and its modified example 30b that constitute the insect monitoring device A1 in the following respects.

[0070] Unlike storage sections 31a and 31b, which are partitioned into multiple storage spaces S12a to 12d, each storage section 31c (31ca, 31cb) is partitioned into only one storage space S12c (S12ca, S12cb) for storing one attractant 12. That is, one attractant 12 is detachably stored in the single storage space S12c partitioned into each storage means 30da, 30db. For example, as shown in Figure 5, attractant 12a is stored in the storage space S12ca partitioned into storage section 31ca, and attractant 12b is stored in the storage space S12cb partitioned into storage section 31cb. The method of storing the attractant 12 is not particularly limited and can be, for example, fixed to the inner surface of storage section 31c or suspended from the top of the lid 32. Storage sections 31ca and 31cb are connected to a single first space S1 via a connecting section 45, which will be described later.

[0071] The opening / closing mechanism 38 is formed in a columnar shape and configured to move up and down, as shown in Figure 5, for example. As the opening / closing mechanism 38 moves up and down, the lid portion 32 also moves up and down. This allows the lid portion 32 to be either open or closed relative to the storage portion 31c (its upper part). In this way, each of the opening / closing mechanisms 38a and 38b is configured so that the lid portions 32a and 32b can be opened and closed relative to the respective storage portions 31ca and 31cb (their upper parts). The opening / closing mechanisms 38a and 38b can be opened and closed individually. For example, as shown in Figure 5, the opening / closing mechanism 38a opens the storage space S12ca, while the opening / closing mechanism 38b closes the storage space S12cb. The opening / closing mechanism 38 is not particularly limited as long as it has a structure that can open and close the storage space S12c, and as shown in Figure 5, the lid portion 32 may move up and down (vertically) relative to the storage portion 31c, or it may have a structure that moves horizontally.

[0072] (Control mechanism) Control mechanism C is a mechanism that controls the operation (opening and closing) of multiple opening and closing mechanisms 38a and 38b that constitute the storage means 30da and 30db, respectively, in a unified manner. In the insect monitoring device A3, control mechanism C controls the opening and closing of opening and closing mechanisms 38a and 38b individually. As shown in Figure 5, control mechanism C opens only one of the opening and closing mechanisms 38 (38a in Figure 5) to open the storage space S12ca, while closing the other opening and closing mechanisms (38b in Figure 5) to close the storage space S12cb. Note that since the insect monitoring device A3 controls the operation of multiple opening and closing mechanisms 38a and 38b both in a unified manner and individually, it is sufficient to have only one control mechanism C. Note that control mechanism C can be, for example, a commercially available drive means such as a motor, actuator, or belt conveyor.

[0073] [Other configurations] As shown in Figure 5, the insect monitoring device A3 comprises one insect processing means 13 and a counting means 40 consisting of one imaging device 40a, one weight sensor 40b, and two passage sensors 40ca and 40cb. Note that the counting means 40 is not limited to the above and may be selected as needed.

[0074] The insect monitoring device A3 has two connecting parts 45 (45d, 45e) on opposing sides of the main body 11 of the device, connecting a first space S1 to a plurality of storage means 30da, 30db (with their internal storage spaces S12ca, S12cb). Two connecting spaces S4 (S4d, S4e) are partitioned through each connecting part 45d, 45e, connecting the first space S1 to each storage space S12ca, S12cb. Openings 8 (8d, 8e) are formed in each connecting part 45d, 45e, connecting S4d, S4e to the first space S1. In addition, slopes 46 (46d, 46e) are formed in each connecting part 45d, 45e, sloping from each storage means 30da, 30db toward each opening 8d, 8e. In this way, the attracted insects move from their respective storage spaces S12ca and S12cb into a single first space S1 via the respective connecting spaces S4d and S4e, the slopes 46d and 46e, and the openings 8d and 8e.

[0075] The insect monitoring device A3 may also have passage sensors 40ca and 40cb placed below the openings 8d and 8e in the first space S1, respectively, to count insects as they move from the openings 8d and 8e into the first space S1.

[0076] The insect monitoring device A3, configured as described above, is equipped with multiple storage means 30da, 30db depending on the type and number of attractants 12, and is equipped with an insect processing means 13, a control mechanism C, and a counting means 40, all of which are commonly provided in a single first space S1. In the insect monitoring device A3, each storage space S12 (S12ca, S12cb) partitioned by each storage means 30da, 30db is an attractant space for attracting insects, the connecting space S4 is a moving space for moving insects from each storage space S12ca, S12cb to the first space S1, and the first space S1 can be described as a counting space for processing insects and counting the insects after processing. The storage means 30da, 30db are configured to be attachable to the device (the upper part of each connecting part 45d, 45e).

[0077] The insect monitoring device A3 (its operation flow) shown in Figure 5 may be configured as follows, for example. In the following example, one attractant 12a is selected from among multiple attractants 12a and 12b stored in each of the storage means 30da and 30db (their storage sections 31ca and 31cb) according to the insect P. In this case, first, the control mechanism C operates only the opening / closing mechanism 38a (opens), opening only the storage space S12ca where the attractants 12a partitioned within the storage section 31ca are stored. At this time, the opening / closing mechanism 38b other than the opening / closing mechanism 38a is not operated (closed), and the storage space S12cb other than the storage space S12ca is closed. Subsequently, one type of attractant 12a scattered from the opened storage space S12ca attracts the insect P into the storage space S12c through the opening of the opening / closing mechanism 38a. The attracted insect P moves from the storage space S12c to the first space S1 via the connection space S4d and the opening 8d, using the slope 46d of the connection part 45d. The captured insect P is then killed or immobilized by the insect processing means 13 within the first space S1. After that, the insect P lying motionless on the bottom surface of the main body 11 is counted by the counting means 40. Alternatively, the insect P moving from the storage space S12c to the first space S1 may be counted by the counting means 40 (pass sensor 40ca, etc.) before processing. After counting, the opening / closing means 14 (disposal means) is automatically opened and closed at a predetermined time (for example, a time when the activity of insect P decreases) or at predetermined intervals (for example, every day), and the insect P is automatically disposed of. Through this series of operations, the insect monitoring device A3 returns to the state before monitoring started (initial state).

[0078] Next, we will explain the operation flow of the insect monitoring device A3 when changing the monitoring target from insect P to a different type of insect Q. In this example, one attractant 12b is selected according to insect Q. The control mechanism C is used to activate (open) only the opening / closing mechanism 38b and deactivate (close) the opening / closing mechanism 38a. In this way, by operating the control mechanism C, the storage space S12 that is opened can be swapped, and the attractant 12 released (exposed) outside the device can be changed. Furthermore, the insect monitoring device A3 is equipped with separate storage means 30da and 30db, so that the storage spaces S12ca and S12cb are physically separated, making it less likely for the attractant 12b to be contaminated with other attractants 12a within the device, and the attractant effect is easily maintained. As a result, insect Q can be attracted by one type of attractant 12b scattered from the opened storage space S12cb, and insect Q can be captured in the first space S1 through the opening of the opening / closing mechanism 38b. The subsequent flow is as described above.

[0079] <Effects> As described above, the insect monitoring device A3 according to this embodiment provides the same effects as the insect monitoring device A1 of the first embodiment and the insect monitoring device A2 of the second embodiment described above. The insect monitoring device A3 is configured to have multiple storage spaces S12ca and S12cb by providing multiple storage means 30d, each of which partitions a single storage space S12c according to multiple attractants 12. The multiple storage spaces S12ca and S12cb are connected to a single first space S1. Therefore, the insect monitoring device A3 is configured to attract insects with a single attractant (e.g., 12a) stored in each storage space S12c, process the attracted insects in the first space S1, and count them. Furthermore, the insect monitoring device A3 is configured to control the operation (opening and closing) of multiple opening and closing mechanisms 38, which individually open and close the multiple storage spaces S12c, all at once using a single control mechanism C. The insect monitoring device A3 only requires the configuration of multiple storage means 30d according to the type of attractant 12, and there is only one storage space S12c partitioned within each storage section 31c, making its structure simpler (easier) than the storage means 30a and its modified example 30b that constitute the insect monitoring device A1. Therefore, the insect monitoring device A3 also has a simple (easier) structure.

[0080] Modified example of the insect monitoring device according to the third embodiment. The insect monitoring device A3 may also be modified A3' shown in Figure 6. Modified A3' may further include a connecting portion 45f that demarcates a connecting space S4f that connects two connecting spaces S4d and S4e. In this structure, for example, an opening 8f is formed on the upper surface of the main body 11 that connects the connecting space S4f (connecting portion 45f) and one first space S1. In modified A3' configured as described above, one passage sensor 40c only needs to be placed in, for example, the connecting portion 45f, so the passage sensors 40c can be consolidated into one.

[0081] (Other embodiments) Depending on the number of attractants 12, a configuration may be made by combining multiple insect monitoring devices A1 (or modified versions thereof) according to the first embodiment. In this configuration, one storage space S12 should be formed within the storage means 30. For the opening and closing mechanism, for example, a modified version of the opening and closing mechanism 37 described above can be applied. Furthermore, a single control mechanism may be configured to control the opening and closing of multiple opening and closing mechanisms provided for each device as a whole, in a single operation.
