Description

[0001] IMAGE-BASED DEVICE FOR THE DETECTION OF ARCHIVEN'S FEET

[0002] The present invention relates to an image-based device for the detection of arthropods using an adhesive trap attached to the image-based device. The invention relates in particular to the attachment of the adhesive trap to the device and a method for using the device.

[0003] Approximately two-thirds of currently known animal species belong to the arthropods (phylum Arthropoda), 85% of which are insects. A significant proportion of arthropods are phytophagous: these animals feed on plants and can impair growth, cause damage through sucking and feeding, and transmit viral diseases. This can lead to, for example, substantial losses in yield and quality in crop cultivation.

[0004] Besides these pests, there are arthropods that are beneficial in the cultivation of crops. These beneficial insects can be natural enemies of pests, decimating pest populations or preventing their further reproduction because the pests serve as food for them or their offspring. Other beneficial insects are essential for plant reproduction: bees, bumblebees, flies, and butterflies, in particular, collect pollen from a flower while searching for nectar, transfer it to neighboring flowers, and thus ensure fertilization.

[0005] In modern agriculture, the detection and identification of pests and / or beneficial insects within agriculturally used areas plays an important role.

[0006] Sticky traps such as adhesive boards and especially colored sticky boards are frequently used to monitor pest infestations. Many pests are attracted by the color of the board. The pests then get stuck to the adhesive on the board.

[0007] Sticky traps are used and positioned differently depending on the target organism, crop, and environment. In an agricultural field, sticky traps are generally placed at a height corresponding to the plants, as many pests congregate near the plants. The traps should be adjusted regularly to keep pace with plant growth. The spacing between the sticky traps depends on the type of pest and the plant density. For general monitoring, a greater distance can be chosen, while for targeted monitoring or control of pest outbreaks, the traps should be placed closer together. The number of sticky traps depends on the size of the field and the purpose of the monitoring. For effective monitoring, enough sticky traps should be distributed to obtain a representative picture of the pest populations.In greenhouses, sticky traps are often placed near vents, doors, and other entry points for pests to quickly capture invading insects. They can also be placed between rows of plants to facilitate monitoring. As in the field, in greenhouses, sticky traps should be placed at plant height or near flowers to effectively attract specific pests. The color of the sticky traps is chosen based on the target organisms. Yellow traps, for example, attract a variety of flying insects, while other colors may be more effective for specific pests. The sticky traps are checked regularly. While counting the pests caught in a trap can help determine damage thresholds, this is tedious and prone to error.

[0008] W02020 / 058175A1 describes an image-based device for the detection of arthropods, which can also utilize sticky traps. This device enables the automated, image-based evaluation of sticky traps. W02020 / 058175A1 does not specify whether and how the sticky traps are fixed to the collection area for automated, image-based evaluation. However, fixing the sticky traps in such a device presents a challenge. It must be possible to quickly replace the sticky trap (e.g., if it loses its stickiness). Furthermore, the traps may be attached to difficult-to-access locations. At the same time, the dimensional stability of the sticky trap attached to the device's collection area must be high to prevent warping or waviness due to temperature fluctuations, humidity, or mechanical stress (such as...).to prevent this (due to wind). The problem becomes even more complex when adhesive traps of different sizes are to be used.

[0009] The present invention addresses these problems.

[0010] A first object of the present invention is a device comprising a collection area,

[0011] Mounting system for an adhesive trap, an image acquisition unit, a transmitter unit and a control unit, wherein the adhesive trap is attached to the collection area by the mounting system and wherein the control unit is configured to cause the image acquisition unit to produce images of the adhesive trap attached to the collection area and to cause the transmitter unit to send the produced images and / or information about the produced images to a computer system via a network.

[0012] Another object of the present invention is a method comprising the steps:

[0013] Attachment of an adhesive trap to a device comprising a collection area, an attachment system for an adhesive trap, an image acquisition unit, a transmission unit and a control unit, wherein the adhesive trap is attached to the collection area of ​​the device by means of the attachment system,

[0014] Setting up multiple devices with the attached adhesive trap in an area,

[0015] Generating images of the adhesive trap of each device,

[0016] Transmitting information concerning the image captures to a computer system,

[0017] Analyzing the transmitted information and generating information on the pests and / or beneficial organisms present in a sub-area, transmitting the information on the pests and / or beneficial organisms present in a sub-area to one or more users.

[0018] The invention is explained in more detail below, without distinguishing between the subject matter of the invention (device, method). Rather, the following explanations are intended to apply analogously to all subject matter of the invention, regardless of the context (device, method) in which they are made.

[0019] If the present description or the claims mention steps in a sequence, this does not necessarily mean that the invention is limited to that sequence. Rather, it is conceivable that the steps could also be carried out in a different sequence or even in parallel; unless one step builds upon another, which makes it essential that the building step be carried out subsequently (which will be clear in the specific case). The sequences mentioned thus represent preferred embodiments of the invention.

[0020] With the aid of the present invention, the presence of pests and / or beneficial organisms in an area can be determined simply and efficiently. It should be noted, however, that sticky traps are generally used for monitoring and controlling pests in agriculture and horticulture. Their main purpose is to capture and reduce harmful arthropod populations. However, sticky traps cannot distinguish between pests and beneficial organisms. This means that they can also capture beneficial arthropods if they come into contact with the traps. There are, however, specific applications where sticky traps are used to attract and collect specific beneficial organisms, for example, for research purposes or for recolonizing areas where certain beneficial organisms are to be promoted.In such cases, the traps are designed and placed to effectively attract the desired beneficial insects while minimizing the unintentional capture of non-target species. Generally, however, it is important to exercise caution when using sticky traps near beneficial arthropod populations to minimize the unintentional capture and associated harm to these beneficial organisms. Strategies for minimizing the unintentional capture of beneficial insects may include the careful selection of trap color and location, as well as the use of attractants specifically designed for the target pests.

[0021] The term "pest" is preferably understood to mean an arthropod that can appear during the cultivation of crops and damage the crop or negatively affect the harvest of the crop.

[0022] Preferably, it is an animal pest from the group of insects (in the various stages from larva (caterpillar, false caterpillar) to the adult stage) or arachnids.The pest is particularly favored by agricultural pests such as codling moth, aphid, thrips, fruit peel moth, Colorado potato beetle, cherry fruit fly, cockchafer, European corn borer, plum fruit moth, rhododendron leafhopper, seed moth, scale insect, gypsy moth, spider mite, grape berry moth, walnut fruit fly, whitefly, large cabbage stem weevil, spotted cabbage stem weevil, pollen beetle, cabbage seed weevil, cabbage seed midge, or flea beetle, or by forest pests such as aphid, pine jewel beetle, bark beetle, oak jewel beetle, oak processionary moth, oak tortrix moth, spruce ermine sawfly, common woodworm, large brown bark beetle, pine bush sawfly, pine moth, pine looper moth, small spruce sawfly. Nun moth, horse chestnut leaf miner, gypsy moth or powderpost beetle.

[0023] A "beneficial organism" is preferably an arthropod that uses a pest as a food source or host, or that is important for a successful harvest for other reasons (e.g., as a pollinator). Preferably, the beneficial organism is an insect (in its various stages from larva (caterpillar, false larva) to adult) or an arachnid. A pollinator (pollen donor) such as a bee, bumblebee, fly, or butterfly is particularly preferred.

[0024] The term "cultivated plant" refers to a plant that is intentionally grown as a useful or ornamental plant through human intervention.

[0025] The term "area" refers to a spatially definable area of ​​the Earth's surface where plants grow. Preferably, the area is at least partially used for agriculture, with crops being planted, fertilized, and harvested in one or more fields. The area can also be, or encompass, a forested area (e.g., a forest). Gardens, parks, and similar spaces where plants exist solely for human enjoyment also fall under the definition of an area. The term also includes greenhouses.

[0026] To determine the presence of pests and / or beneficial organisms in an area, at least one device according to the invention is used; preferably, several devices according to the invention are distributed throughout the area. Preferably, several devices according to the invention are set up or suspended in one or more fields of a specific crop (e.g., rapeseed, grapes, potatoes, fruit, or the like) or in stands of specific plants (e.g., oak forest), since such areas have a characteristic fauna. Preferably, the fauna (pests / beneficial organisms) living in the areas is analyzed by applying the invention.

[0027] With the aid of a device according to the invention, it is possible to determine which pests / beneficial insects and how many pests / beneficial insects are present in the area where the device is set up.

[0028] The device according to the invention comprises a collection area, a fastening system for an adhesive trap, an image acquisition unit, a transmission unit and a control unit.

[0029] The collection area is the part of the device to which the sticky trap is attached. It is conceivable that a device according to the invention has several collection areas. It is also conceivable that a device according to the invention has different collection areas to which, for example, sticky traps for different pests are attached. The collection area is preferably a flat surface with a round, oval, elliptical, or rectangular (triangular, square, pentagonal, hexagonal, or generally n-sided, where n is an integer greater than or equal to three) cross-section. Preferably, the cross-section is round or rectangular (in particular, square). Preferably, the area of ​​the collection area is larger than the sticky trap to be attached to it.

[0030] In a preferred embodiment, the collection area has a flat surface arranged so that it is inclined relative to the horizon when the device according to the invention is placed on the ground or attached to a plant. The horizon runs perpendicular (at an angle of 90°) to the direction of gravity. The flat surface is thus arranged so that it and the horizon form an angle greater than zero and at most 90°. Preferably, the flat surface and the horizon form an angle in the range of 2° to 88°, more preferably in the range of 5° to 80°, and even more preferably in the range of 10° to 70°. This allows rainwater or dew to run off the surface easily.

[0031] The adhesive trap to be attached to the collection area preferably has a similar cross-section to the collection area described above. The adhesive trap preferably comprises a flat and rigid material, such as a plastic, paper, or cardboard sheet, coated on at least one side with an adhesive. Non-drying adhesives are typically used for the adhesive traps and are applied to the surface of the trap. These adhesives are specially formulated to ensure high adhesive strength without containing toxic or harmful ingredients. The adhesives are generally non-toxic and environmentally friendly to ensure safe use in various environments. They are designed to effectively capture a wide range of insects without being harmful to humans or animals.

[0032] The sticky trap and / or the collection area can be colored (e.g., yellow or red) to attract specific pests and / or beneficial insects. In addition to or instead of color, other attractants can be used. For example, a pheromone or scent that mimics a food source could be used. Another possibility is the use of a source of electromagnetic radiation in the infrared, visible, and / or ultraviolet range to attract (specific) arthropods. Sounds that imitate, for example, mating males and / or females are also conceivable. The use of special patterns that mimic, for example, a plant is also possible. Preferably, one or more attractants are used that maintain a consistent effect at least during the period between the device's initial setup and its first maintenance.Since a color, pattern, shape, or similar attractant typically remains constant over such a period, it has an advantage over a pheromone, which can dissipate quickly. In an alternative embodiment, however, the device can also be designed such that the pheromone's dissipation is reduced by a housing (preferably a transparent one). The housing can, for example, be attached to the edge of the collection area and enclose the collection area with the attached adhesive trap. The housing includes at least one opening through which the arthropods can enter.

[0033] Preferably, the device according to the invention has means by which it can be positioned on or in the ground. Preferably, the device can be anchored in the ground to prevent it from tipping over, for example, in a storm. Preferably, means are provided by which the distance between the ground and the collection area can be varied. An example of such a height adjustment is a telescopic pole, one end of which can be anchored in the ground and the other end of which the collection area is attached. Another example of a height adjustment is a lifting platform. Such a variable height adjustment makes it possible to position the collection area above plants, so that flying insects can detect the collection area when flying over the plants and land there.The variable height adjustment allows the height of the collection area (distance from the ground) to be adapted to the growing plants, preventing the surrounding plants from obscuring the collection area. In a preferred embodiment, the height adjustment is automatic. It preferably adjusts itself so that the collection area is always above or at the same height as the surrounding plants. This can be achieved by distance sensors and / or light sensors. It is also conceivable that the device according to the invention has means by which it can be attached to a plant, such as a hook, a loop, or a strap for attaching it to a branch, twig, or trunk.

[0034] The device according to the invention further comprises one or more image acquisition units. Digital images can be generated with such an image acquisition unit. An image acquisition unit comprises an image sensor and optical elements. The image sensor is a device for electrically capturing two-dimensional images of light. These are typically semiconductor-based image sensors such as CCD (CCD = charge-coupled device) or CMOS (CMOS = complementary metal-oxide semiconductor) sensors. The optical elements (lenses, apertures, and the like) serve to create the sharpest possible image of the object from which a digital image is to be generated on the image sensor. The image acquisition unit is positioned such that the entire collection area, or at least a part of it, is imaged onto the image sensor.It is conceivable to use multiple image acquisition units, each capturing different areas of the collection area on its respective image sensor. When using multiple image acquisition units in this way, it is advantageous if the captured areas overlap at least partially, so that a complete image can be more easily generated from the individual images at a later time.

[0035] The device according to the invention preferably comprises a tripod to which the image capture unit is fixed or can be reversibly fixed. This tripod is preferably located at a defined and constant distance from the collection area, thus ensuring a defined and constant distance between the image sensor and the collection area. This facilitates focusing the collection area. The tripod can, for example, comprise one or more legs (preferably at least two) that are fixed to the collection area and a bracket that makes it possible to secure the image capture unit in a fixed position.

[0036] It is conceivable that a grid or net (generally referred to as a barrier) is installed above the collection area to prevent leaves or similar debris (dirt) from entering it. The sides of the collection area preferably remain clear so that pests and / or beneficial insects can enter from the sides. However, it is also conceivable that the mesh size of the net or the grid spacing is dimensioned so that only (specific) pests and / or (specific) beneficial insects can pass through; in such a case, the net or grid can also extend over the sides.

[0037] To image the collection area onto one or more image sensors, a light source is required to illuminate the collection area so that light (electromagnetic radiation in the infrared, visible, and / or ultraviolet range of the spectrum) is scattered / reflected from the illuminated collection area towards the image acquisition unit. Daylight can be used for this purpose. However, it is also conceivable to use an illumination unit that provides defined illumination independent of daylight. This is preferably mounted to the side of the image acquisition unit so that no shadow is cast by the image acquisition unit onto the collection area. It is also conceivable that several light sources illuminate the collection area from different directions.

[0038] The device according to the invention further comprises a control unit. The control unit causes the at least one image acquisition unit to take digital images. Images can be taken regularly or irregularly. The control unit can be configured to forward the taken images to the transmission unit for transmission via a wireless network to a separate computer system. The images can then be viewed and / or (automatically) analyzed on the computer system. It is also conceivable that the device according to the invention has an evaluation unit configured to automatically analyze the taken images. The analysis can serve to determine the number of pests and / or beneficial organisms present in the collection area. The analysis can also serve to identify the species of pests and / or beneficial organisms present in the collection area.

[0039] The transmitting unit of the inventive device is configured to send information concerning one or more image captures to a computer system via a network. This information can be the image(s) themselves. However, it is also conceivable that this information consists of the results of the analysis by the evaluation unit, i.e., the number of pests and / or beneficial organisms present and / or the respective species identified. It is also conceivable that an alarm signal is sent if the automated analysis of at least one image capture reveals that a specific pest has been identified and / or the number of (specific) pests and / or (specific) beneficial organisms exceeds or falls below a predefined threshold. The presence of dirt that, for example, cannot be removed from the collection area with a cleaning agent can also trigger an alarm.The transmitting unit can be configured to transmit information via a mobile network (e.g., GSM: Global System for Mobile Communications, GPRS: General Packet Radio Service, UMTS: Universal Mobile Telecommunications System, LTE: Long Term Evolution), via a WLAN (Wireless Local Area Network), via Bluetooth, via DECT (Digital Enhanced Cordless Telecommunications), via a low-power wide area network (LPWAN or LPN) such as a Narrowband IoT network, and / or via a combination of different transmission methods. In a preferred embodiment, the transmitting unit is configured to transmit the information to a base station via a short-range (radio) link, from which the information is then forwarded via cable and / or a long-range radio link.The term "short-range" means that the distance between transmitter and receiver is preferably no greater than 5 km, and particularly preferably no greater than 1 km. A greater distance than the specified maximum distance would compromise the reliability of data transmission from transmitter to receiver. The term "long-range" means that the distance between transmitter and receiver is preferably greater than 1 km, and particularly preferably greater than 5 km. Communication via the short-range connection can be achieved, for example, using radio, ultrasound, and / or (laser) light.

[0040] It is conceivable to adjust the times for capturing images according to environmental conditions. For example, the control unit could be configured so that no images are taken at night. Such a configuration could be achieved, for example, using a brightness sensor or a timer.

[0041] Devices according to the invention are preferably distributed over an area. Their spacing is typically between 10 meters and 10 kilometers. Preferably, they are placed in fields of a specific crop (e.g., rapeseed), since such fields have a characteristic fauna. Preferably, the fauna (pests / beneficial organisms) living in the fields of the specific crop is analyzed by carrying out the invention.

[0042] In a preferred embodiment, the device according to the invention includes means for determining the location of the devices. It is conceivable that the device has a GPS sensor (GPS: Global Positioning System) or another sensor of a global navigation satellite system (GNSS) with which the location of the device can be determined.

[0043] A "computer system" is a system for electronic data processing that processes data using programmable instructions. Such a system typically comprises a "computer," the unit containing a processor for performing logical operations, as well as peripherals. In computer technology, "peripherals" refers to all devices connected to the computer that serve to control the computer and / or as input and output devices. Examples include monitors (screens), printers, scanners, mice, keyboards, drives, cameras, microphones, speakers, etc. Internal connections and expansion cards are also considered peripherals in computer technology. Today's computer systems are often categorized into desktop PCs, portable PCs, laptops, notebooks, netbooks, tablet PCs, and so-called handhelds (e.g., smartphones); all of these systems can be used to implement the invention.Input into the computer system is provided via input devices such as a keyboard, mouse, microphone, and / or the like. Input also includes selecting an entry from a virtual menu or list, clicking a checkbox, and similar actions.

[0044] The device(s) according to the invention and the computer system are connected to each other via a network, enabling the device(s) to transmit information (data, images, status information, sensor data, or the like) to the computer system. It is also conceivable that the system according to the invention is configured such that the computer system can transmit information or control commands to the device(s). The network connecting the computer system and the devices is at least partially a wireless network. Typically, information is transmitted from a device via a transmitter unit to a base station, from which it is forwarded (possibly via further stations) to the computer system wirelessly and / or via cable.

[0045] In one embodiment of the present invention, the device(s) transmit the generated images to the computer system. The transmitted images are analyzed on the computer system; the number of pests and / or beneficial organisms present in the collection area is determined, the species present are identified, and, if one or more plant analysis devices are present, the images are examined with regard to the status of the plants and / or the presence of damage, and the extent of the damage is determined, if applicable. In an alternative embodiment, the generated images are analyzed by an evaluation unit of the respective device. For example, the number of pests / beneficial organisms present in the collection area can be determined. This number can then be transmitted to the computer system. The species present can be identified.The species names can then be transmitted to the computer system. The status of the cultivated plants can be determined and then transmitted to the computer system. It is conceivable that the generated images could also be transmitted to the computer system. It is conceivable that a generated image, along with the results of the analysis of the respective device, could be transmitted to the computer system. It is conceivable that the generated images could only be transmitted to the computer system upon a user request. The analysis of the images generated by the devices can serve to determine whether an organism in the image is a harmful organism, a pest, a beneficial organism, or an organism irrelevant to the cultivation of the crops.Accordingly, identification can mean assigning an organism to one of three categories: "harmful," "beneficial," or "neutral." Preferably, the identification of a pest serves to identify measures that can be taken against it. A measure to be taken could, for example, be the application of a specific pesticide. However, identification can also be understood as the assignment of individual pests / beneficial organisms to a taxon, i.e., their classification within a class, order, superfamily, family, subfamily, tribe, genus, species, subspecies, or an intermediate level in the sense of biological taxonomy. The identification and counting of pests / beneficial organisms is automated.This means that a user does not have to count and identify the arthropods in an image themselves, but rather that the image is processed by a computer program in the working memory of a computer system and fed into image processing and image recognition algorithms. Using these algorithms, the image is analyzed, possibly prepared (filtering and similar operations), and features are extracted that allow conclusions to be drawn about how many arthropods are present and what species they are. Such algorithms are described in the prior art. It is conceivable to use an artificial neural network for the identification of pests / beneficial organisms, which has been previously trained on a large number of images of known pests / beneficial organisms. Preferably, further information is used for the identification of the pests / beneficial organisms. For example, location information (e.g., geo-coordinates) can be used.If the device in question is located in Germany, for example, different pests / beneficial insects are likely to be present than if the device were located in Brazil, for instance. The current season is also important information that can be used. Depending on the time of year, different pests / beneficial insects may appear. Furthermore, the plants being cultivated (crops, protected plants, sacrificial plants) can provide information about the pest / beneficial insect.

[0046] Preferably, the mounting system of the device and at least a portion of the collection area each comprise a magnetic element. These magnetic elements are used to attach the adhesive trap to the collection area of ​​the device by means of the mounting system. The magnetic elements can be fixed to or incorporated into the mounting system (e.g., with an adhesive) or repositionable. The poles of the magnetic elements of the mounting system and of the at least portion of the collection area of ​​the device are aligned such that they attract each other and thus generate a strong holding force. This complementary arrangement ensures that the magnets work together effectively to provide the required holding force without damaging the adhesive trap.The magnetic elements can be round, rectangular, or specially shaped, preferably depending on the design of the fastening system and / or the collection area of ​​the device. The holding force of the magnetic elements is selected so that the adhesive film remains in its fixed position under various environmental influences, such as strong winds.

[0047] The device's mounting system preferably comprises at least one holder for attaching the adhesive trap to the device's collection area. A holder is a device or structure that serves to attach and hold the adhesive trap on the device's collection area. Such a holder can have various shapes and sizes (e.g., oblong, cylindrical, circular, semicircular, rectangular, square, etc.) and be made of different materials (such as plastic, metals, etc.).

[0048] In a further embodiment of the invention, the mounting of the device's fastening system comprises at least one magnetic element. This magnetic element is preferably not in contact with the adhesive trap during (and after) its attachment to the device's collection area. This is ensured by ensuring that the mounting's contact points on the adhesive trap do not include any magnetic elements. This prevents the magnetic elements from being contaminated by the adhesive of the traps.

[0049] Preferably, the device's mounting system comprises a bracket, which in turn includes at least one and preferably at least two mounting strips. The mounting strip is typically elongated and narrow, although the exact shape may vary depending on the specific design and intended use. The mounting strip may be flat or slightly curved. Its length can vary depending on the number of support points and / or brackets. Mounting strips may also have different profiles, such as rectangular, round, or oval. At least two mounting strips are preferred so that the adhesive trap can be attached to the device's collection area at at least two opposite ends using the mounting strips. This also ensures that the adhesive trap can be fixed flat and with slight tension.This largely prevents the formation of waves in the fixed adhesive trap, which is advantageous for image capture by the image acquisition unit.

[0050] In another embodiment, the contact points of the holder that come into contact with the adhesive trap during (and when) the adhesive trap is attached to the collection area of ​​the device are minimized. This can be achieved, for example, by reducing the contact area (i.e., the contact points) between the holder and the support surface (i.e., the adhesive trap). For instance, the support surface of a holder strip can be reduced to a narrower width by means of the edge, which reduces the contact area between the strip and the support surface. Such a design is also advantageous with regard to minimizing adhesive residue from the adhesive trap on the holder (due to the reduced contact area), for example, when changing adhesive traps. This also reduces the cleaning effort required for the adhesive trap mounting system.The reduced contact surface can be made of, for example, plastic or metal, the latter being where the holding force of the magnetic elements of the holder is determined by additional magnetic elements that are not in direct contact with the adhesive trap (or the collecting area of ​​the device). In a further preferred embodiment, the retaining strip comprises an edge whose structure tapers towards the contact surface, i.e., gradually becomes thinner or narrower (as shown in Figures 5d and 5e). In such an embodiment, for example, an edge of the adhesive strip can form an inverted triangle in the profile, facing the contact surface.

[0051] According to the invention, the mounting system for the adhesive trap comprises at least one, and preferably at least two, mounting strips, and the at least one mounting strip forms at least a partial cavity. That is, the mounting strip has a cavity or recess along its length. Magnetic elements can be incorporated within this area of ​​the strip. The magnetic elements can be present at specific points or continuously within the mounting strip. A further embodiment of the mounting system for the adhesive trap comprises the bearing points of the mounting, and in particular of the mounting strip, forming an at least partially segmented or continuous frame. That is, the bearing surface of the mounting, and in particular of the mounting strip, is reduced to a narrower width by the edge, and this bearing surface forms an at least partially segmented (i.e.,interrupted) or a continuous frame (see, for example, Figure 6b).

[0052] In another preferred embodiment, the magnetic elements of at least part of the collecting area of ​​the device occupy a larger area than the magnetic elements of the mounting system, in order to allow for flexible and variable positioning of the mounting system. That is, the magnetic elements of the collecting area cover and / or encompass a larger complementary area than the magnetic elements of the mounting system. This can also be achieved by allowing the magnetic elements of the collecting area to be reversibly repositioned or moved to different locations within the collecting area. Overall, this ensures a wide range of adaptability and diverse arrangements, for example, of the mounting strip on the surface of the collecting area. Different sized adhesive traps (such as 30cm x 20cm, 25cm x 20cm, 20cm x 15cm) can thus be attached to the same device.This is advantageous because, for example, certain sticky trap sizes have become established for certain pests.

[0053] The magnetic elements of the fastening system and at least part of the collection area can be arranged arbitrarily, but preferably at least largely complementarily, to ensure the necessary holding force. For example, the magnetic elements can be incorporated at the respective ends of the mounting strip. Alternatively, the magnetic elements can be arranged at regular intervals along the mounting strips or extend substantially along the entire length of the mounting strip. Preferably, the magnetic elements of the fastening system and at least part of the collection area are distributed as evenly as possible.

[0054] Preferably, according to the invention, the magnetic elements of at least part of the collecting area do not make direct contact with the adhesive trap attached to it. This allows the surface to be made of an easily cleanable material. This prevents the magnetic elements from being affected by the cleaning process. Preferably, the magnetic elements of the collecting area are integrated into the geometric shape of the collecting area in such a way that no protrusion is present (for example, as shown in Figure 7b). That is, it should be ensured as far as possible that all parts are at least flush or arranged in a flat position. This can be achieved by adjusting the geometry of the collecting area.

[0055] Another aspect of the invention relates to a method comprising the steps of:

[0056] Attachment of an adhesive trap to a device comprising a collection area, an attachment system for an adhesive trap, an image acquisition unit, a transmission unit and a control unit, wherein the adhesive trap is attached to the collection area of ​​the device by means of the attachment system,

[0057] Setting up multiple devices with the attached adhesive trap in an area,

[0058] Generating images of the adhesive trap of each device,

[0059] Transmitting information concerning the image recordings to a computer system,

[0060] Analyzing the transmitted information and generating information on the pests and / or beneficial organisms present in the area or a sub-area thereof,

[0061] Transmitting information about pests and / or beneficial insects present in the area or a sub-area thereof to one or more users. The sticky trap can preferably be attached to the collection area of ​​the device by a single user. For example, the sticky trap can be attached to one side of the collection area using an adhesive strip. A second adhesive strip can then be used to securely fix the sticky trap to the opposite side of the collection area. Alternative mounting systems, such as a square frame, are also conceivable, allowing a single user to attach the sticky trap to the collection area of ​​the device. Devices already equipped with sticky traps can be set up in the area. Alternatively, the sticky traps can be attached on-site at the respective location within the area where the device is installed.The use of the respective device in the field is carried out as described above.

[0062] Other embodiments of the present invention are:

[0083] The invention is explained in more detail below with reference to figures and examples, without limiting the invention to the features and combinations of features mentioned in the figures and examples.

[0084] They show:

[0085] Figure 1 schematically shows the device (10) from an elevated position, so that the device (10) is viewed from below. The device comprises a collection area (11) and a mounting system (both 12a) for an adhesive trap (13). The mounting system is illustrated by means of two mounting strips (each 12a) which, on two opposite sides of the exemplary rectangular adhesive trap (13), secure the adhesive trap to the collection area (11) of the device. The device shown includes a "two-legged" tripod (each 14) to which the image acquisition unit (15) is fixed or can be reversibly fixed. The lens (15a) of the image acquisition unit (15) is schematically indicated by a dashed line. The lens (15a) is directed towards the surface of the adhesive trap (13). The transmitter unit and the control unit of the device are not shown. Figure 2 schematically shows a frontal view of the device (10).The device comprises a collection area (11) and a mounting system (both 12a) for an adhesive trap (13). The mounting system is shown by way of example with two mounting strips (each 12a) which, on two opposite sides, secure the exemplary rectangular adhesive trap (13) to the collection area (11) of the device. This ensures that the adhesive trap can be mounted without rippling and remains in the fixed position even under varying environmental conditions. The device includes a two-legged tripod (each 14) to which the image acquisition unit (15) can be attached. The lens (15a) of the image acquisition unit (15) is directed towards the surface of the adhesive trap (13). The two mounting strips (12a) each include magnetic elements (16a), which are shown with a dashed line. The collection area (11) includes magnetic elements (16b), which are shown with a dashed line.In this schematic representation, the magnetic elements (16b) of the collection area (11) occupy a larger area than the magnetic elements (16a) of the fastening system, thus enabling flexible and variable positioning of the fastening system. The transmitter unit and the control unit of the device are not shown.

[0086] Figures 3a, b, and c schematically show four variants of the device (10) from the underside. The collecting area (11) and the magnetic elements (16b) visibly (or invisibly) incorporated therein, indicated by dashed lines, are shown. In the first variant (Figure 3a), only the four corner regions of the square collecting area are provided with magnetic elements (16b). In the second variant (Figure 3b), several areas along two opposite sides of the collecting area are provided with magnetic elements (16b). In the third variant (Figure 3c), continuous magnetic elements (16b) are incorporated along two opposite sides of the collecting area. A further variant is shown in Figure 3d, in which the collecting area comprises several strips of continuous magnetic elements (16b) on the two opposite sides of the collecting area.Other variations are also conceivable, such as the presence of magnetic elements along each side of the collection area or the presence of magnetic elements across the entire collection area. These variations make it possible to attach adhesive traps of different sizes using the same device.

[0087] Figures 4a, b, and c schematically show three possible embodiments of an adhesive strip (12a). Here, too, the magnetic elements (16a) can be incorporated at the respective ends of the adhesive strip (first variant, Figure 4a). In the second variant (Figure 4b), the magnetic elements (16a) are distributed at intervals along the entire length of the adhesive strip. In the third variant, the magnetic elements (16a) are incorporated along the entire length of the adhesive strip.

[0088] Figures 5a, b, c, d, and e schematically show five possible mounting strips (12a) in cross-section. The magnetic elements (16a) can take on various shapes and be incorporated into the mounting strip in different ways. In example 5a, the magnetic element is inserted flush with the top of a recess in the mounting strip. In the other examples 5b to 5e, the magnetic elements are fully embedded, for example, in a cavity of the mounting strip. In examples 5b to 5e, the contact points of the mounting strip that make contact with the adhesive trap when the adhesive trap is attached to the collecting area of ​​the device have been minimized. In these examples, the contact surface of the respective mounting strips has been reduced to a narrower width by the edge, which reduces the contact area between the strip and the contact surface.A continuous tapering of the edge as shown in examples 5d and 5e may be preferred because it improves the stability of the support strip and especially the edge.

[0089] Figures 6a and 6b schematically show another possible embodiment of the mounting strip (12a). In this example, the magnetic element (16a) is incorporated into the mounting strip along its entire length. The bearing surface of the mounting strip is reduced to a narrower width by the edge, and this bearing surface forms a regularly segmented (i.e., interrupted) frame. Figure 6a shows the mounting strip from an elevated side view. Figure 6b schematically shows the same mounting strip from below.

[0090] Figures 7a, b, and c schematically show three possible embodiments of the device in cross-section, each with the adhesive strip (16a), the adhesive trap (13), and the collection area (11) of the device (10). The adhesive strips (16a) each comprise magnetic elements (16a), and the contact surface of the respective retaining strips on the adhesive trap (13) is reduced to a narrower width by the edge. The collection area (11) comprises magnetic elements (16b) that occupy a larger area than the magnetic elements (16a) of the adhesive strips to allow for flexible and variable positioning of the retaining strips. The magnetic elements (16b) can be incorporated into the collection area of ​​the device in different ways (see different variants in Figures 7a, b, and c). Preferably, as shown, the magnetic elements (16a, 16b) are not in direct contact with the adhesive trap (13).
