Description

Technical Field

[0001] The present invention belongs to the technical field of insect trapping, and more specifically, relates to a locust monitoring and trapping device and a use method thereof. Background Art

[0002] Locusts are an important part of the agricultural, forestry and animal husbandry ecosystems. Many harmful locust species cause varying degrees of damage to agriculture, forestry and animal husbandry. There are more than 10,000 species of locusts in the world, of which about 300 species can cause harm to agriculture, forestry and animal husbandry. There are more than 1,000 known locust species in my country, of which about 60 species can cause harm to agriculture, forestry and animal husbandry. Adults and locust nymphs have the same diet, both are herbivorous, and the adult stage has strong nutritional supplements, accounting for more than 75% of the total food intake in their lifetime. They use chewing mouthparts to bite plant leaves and flower buds into notches and holes. In severe cases, they will eat up the leaves and flower buds of large areas of plants, causing major economic losses to agriculture, forestry and animal husbandry. According to my country's long-term monitoring records, the locusts that cause devastating disasters in agriculture are mainly migratory locusts, which are widely distributed, have a variety of diets, reproduce quickly, and have strong resistance to adversity, making them difficult to prevent and control.

[0003] In addition to transforming the ecological environment of locust areas and reducing locust breeding grounds, chemical pesticides are the main control method for locust control. However, with the development of society, people's living standards are constantly improving, ecological awareness is constantly increasing, and they are paying more and more attention to their own health and environmental quality. Food safety issues, environmental safety issues, biodiversity loss and pesticide residues caused by pesticides have become the biggest threats to human survival and development. At the same time, the Ministry of Agriculture proposed a "double reduction" plan of "zero growth of pesticides and fertilizers" by 2020 in March 2015, and vigorously developed efficient, safe and green control technologies, which have been listed as the key development areas of high-tech industrialization that the country currently prioritizes. This has put forward higher requirements and challenges for the sustainable control of locusts in my country.

[0004] Light trapping technology is a physical control method that uses the behavior of insects to move toward or away from light sources to encourage insects to gather at a fixed location for centralized elimination. It has many advantages such as high efficiency, safety, greenness, environmental protection and no residue. Nowadays, light trapping technology plays an important role in pest monitoring and prevention in my country's agriculture, forestry, fishery, breeding and gardening, and has achieved good results. However, in the process of locust control, the proportion of light trapping technology applied is relatively small, and the design of light trapping equipment lacks rationality. The reason is that there is insufficient understanding of the characteristics of locusts' phototaxis behavior, resulting in poor trapping effect of the equipment on locusts; the spectral range of insect-catching lamp light sources is relatively wide, and there is a broad-spectrum trapping effect. While trapping target pests, they often also trap many other insects and natural enemies, which can easily cause damage to biodiversity and natural ecological balance.

[0005] Therefore, based on the differences in spectral sensitivity, phototaxis and detection techniques of locusts, a locust monitor suitable for various environments is designed and produced. This monitor has the advantages of high locust capture rate, high monitoring accuracy, cleanliness, high degree of automation and simple operation and maintenance. It has good application effects and applicable prospects. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects and technical deficiencies of the existing locust traps, such as the lack of research on locust traps and poor trapping effects, and to provide a locust monitoring and trapping instrument. The locust monitoring and trapping instrument of the present invention is designed according to the living habits and phototaxis of locusts, wherein the trapping part is located above the ground plane, and the collecting part is located below the ground plane. It is designed based on the phototaxis characteristics of locusts, thereby ensuring that locusts can more easily enter the collecting part; in addition, the light source is set as a narrow wavelength focusing light source, which avoids the wide wavelength light source from attracting insects sensitive to other wavelengths, increases the selectivity of the trapped insect species, avoids the accidental killing of other beneficial insects or natural enemies, and avoids the disadvantage of low locust trapping efficiency of point light sources.

[0007] At the same time, in the collection part, in order to accurately monitor the number and age of trapped locusts, a monitoring part was added, which can accurately monitor the number and age of trapped locusts, thus facilitating the statistics, research and prevention of local locusts.

On the other hand, the phototaxis of locusts is a jumping phototaxis, so the collecting part 2 is buried underground, which is in line with the habit of locusts to jump towards light.

[0084] Example 2

[0085] A locust monitoring trapping device, the longitudinal section structure schematic diagram is as follows Figure 4 ( Figure 4 The medium horizontal thick line represents the ground plane, Figure 4 The upper end of the collecting tank 221 is rectangular, and its cross-sectional structure schematic diagram is as follows: Figure 5As shown, it comprises a trapping part 1 and a collecting part 2 which are detachably fixedly connected, wherein the trapping part 1 comprises a light source 11 and a light shielding plate 12;

[0087] The classification and collection part includes a collection tank 221, a high-voltage power grid 222, a conveyor belt 223, a collection box 224 and a motor 225. The collection tank 221 is arranged at the top of the collection part 2, and a high-voltage power grid 222 is arranged inside the collection tank; a conveyor belt 223 is arranged below; the collection box 224 is arranged below the end of the conveyor belt 223, and is used to collect insects transported by the conveyor belt 223; the motor 225 is used to control the transportation of the conveyor belt 223;

[0088] The monitoring part is used to monitor the number of locusts in the collection box 224;

[0089] The power supply device 24 is used to supply power to the entire device.

[0090] In addition, the trapping part 1 is also provided with a bracket 13 for supporting the light source 11, wherein the light source 11 is arranged on the top of the bracket 13.

[0091] In order to ensure that the light emitted by the light source 11 is parallel light as much as possible, a reflective bowl lampshade is also provided to reflect the light emitted by the light source into parallel light and gather it on the light blocking plate.

[0092] The light source 11 can be controlled by a manual switch, a timing switch or a photosensitive switch.

[0093] The light blocking plate 12 is made of light-proof material.

[0094] The light source 11 is a precise LED concentrated light source with a wavelength of 455-465nm. The wavelength of the light source is a narrow wavelength light source specifically set according to the phototropism of locusts, which increases the selectivity of the lured insect species and avoids the accidental killing of other beneficial insects or natural enemies.

[0095] The power of the light source 11 is 100-200w.

[0096] When the locust monitoring trap is in use, the trapping part 1 is placed above the ground level, and the collecting part 2 is placed below the ground level.

[0097] The upper edge of the collecting trough 221 is 5 cm above the ground; if installed in a vegetation planting area, it can be adjusted according to the height of the vegetation. For example, when the device is installed in the grass, the height of the upper edge of the collecting trough 221 above the ground can be appropriately increased according to the height of the grass.

[0098] When the upper end of the collecting tank 221 is rectangular, the high-voltage grid 222 is arranged on two opposite inclined surfaces and is composed of parallel mesh wires, and the lower end of the high-voltage grid extends to the lower end of the collecting tank 221, and the lower end of one inclined surface of the collecting tank 221 is lower than the lower end of the other inclined surface. Figure 3 shown.

[0099] The spacing between adjacent webs is less than 3 locust body widths.

[0100] The horizontal transport direction of the conveyor belt 223 is adjustable.

[0101] The conveyor belt 223 is composed of a first conveyor belt 2231 and a second conveyor belt 2232 having opposite horizontal transport directions. The first conveyor belt 2231 is arranged above the second conveyor belt 2232, and a strip-shaped gap is arranged on the conveyor belt. Figure 6 As shown, the white part represents the gap, and the black part represents the conveyor belt. The first conveyor belt 2231 is provided with fixed connecting pieces at intervals to fix the conveyor belts with gaps to each other.

[0102] The width of the strip-shaped gap on the first conveyor belt 2231 is smaller than the body width of the third-instar locust. Since other types of insects may be trapped during the trapping process, in order to facilitate monitoring of the age and number of trapped locusts, all trapped insects need to be classified, and the conveyor belt 223 is configured to be a first conveyor belt 2231 and a second conveyor belt 2232 with opposite horizontal transport directions, and the first conveyor belt 2231 is provided with a width smaller than the width of the third-instar locust, the purpose of which is to facilitate classification according to the size of the insects.

[0103] The first conveyor belt 2231 and the second conveyor belt 2232 can be aligned in the vertical direction or staggered ( Figure 4 The diagram of the staggered structure is shown in the figure), or the staggered setting can be achieved by changing the length of the conveyor belt.

[0104] The collecting box 224 is composed of a first collecting box 2241 and a second collecting box 2242 , which are respectively arranged below one end of the first conveyor belt 2231 and below the other end of the second conveyor belt 2232 .

[0105] Since the transport directions of the first conveyor belt 2231 and the second conveyor belt 2232 are opposite, the first collecting box 2241 is arranged below the end of one side of the first conveyor belt 2231 to facilitate the collection of larger insects; while smaller insects fall onto the second conveyor belt 2232 through the gap on the first conveyor belt 2231, and are transported in the opposite direction of the first conveyor belt 2231 and fall into the second collecting box 2242.

[0106] The first collection box 2241 is also provided with an automatic baffle 2243 below the entrance. The automatic baffle 2243 can be automatically opened at a set interval time point and then closed. The specific interval time can be set according to the density of locusts. When the density of locusts is large, the interval time is short, for example, it can be set to 1-60 seconds; when the density of locusts is small, the interval time can be extended.

[0107] The monitoring part is composed of an infrared camera 231 and a counter 232, wherein the infrared camera 231 is used to photograph the situation of insects on the automatic baffle 2243 for correction; the counter 232 is used to count the number of locusts on the automatic baffle 2243.

[0108] The housing 21 is provided with a first escape hole 211 which is communicated with the second collection box.

[0109] The housing 21 is also provided with a second escape hole 212. The first escape hole 211 and the second escape hole 212 are both arranged at a position where the housing 21 is below the ground, and when in use, a pipeline needs to be connected separately, and the outlet of the pipeline needs to be ensured to be above the ground.

[0110] The power supply device 24 is a direct power supply, a rechargeable power source (such as Figure 4 and Figure 5 as shown) or solar powered devices (such as Figure 7 shown).

[0111] The solar power supply device is provided with a solar panel 241 and a storage battery 242 (such as Figure 7 The solar panel is detachably arranged on the housing 21 through a bracket. The number of solar panels can be set according to actual application conditions.

[0112] The collecting part 2 is also provided with a drainage system 25 , which is arranged at the bottom of the shell 21 .

[0113] When the locust monitoring trap of this embodiment is in use, the trapping part 1 is located above the ground level, while the collecting part 2 is located below the ground level. This setting is specifically set according to the living habits and phototaxis of locusts. On the one hand, it avoids the wide-wavelength light source from attracting insects sensitive to other wavelengths. On the other hand, the phototaxis of locusts is a jumping phototaxis, so the collecting part 2 is buried under the ground, which is in line with the habit of locusts to jump towards light.

[0114] The locust monitoring trapping device of this embodiment can be used as a single device. Figure 4As shown, when the device is used alone, the length of the light beam of the device is 10m. The collection system of the device can be directly installed underground, with the upper edge of the collection trough 22 exposed 5cm above the ground. When the locusts are attracted by the light beam, they will jump towards the light and fall into the collection trough 22. There are longitudinally arranged wire teeth 2221 on the inside of the collection trough 22. When the locusts touch more than two wire teeth 2221 at the same time, they will be electrocuted to death. They will fall along the collection trough 22 to the first conveyor belt 2231 below. Other small insects will fall from the strip gap on the conveyor belt 2231, fall onto the second conveyor belt 2232, and then be transported to the second collection bucket 2242 on the left. The locusts will be sent to the automatic baffle 2243 on the first collection box 2241 on the right by the first conveyor belt 2231. The insects collected on the automatic baffle 2243 are counted by the infrared counter 232. There may be other insects mixed in it. Therefore, at the interval time point, before the automatic baffle 2243 is opened, the infrared camera 231 takes a photo once for calibration, and then the automatic baffle is opened, and the insects fall into the first collection box 2241 below, and a new round of counting begins, so that the newly captured insects will not be disturbed by the original insects. This device can be connected to the Internet for remote monitoring.

[0115] The locust monitoring trapping device of this embodiment can be used in series with multiple devices, such as Figure 8 As shown, the number of devices connected in series can be determined according to actual usage; they can also be used in a star arrangement, such as Fig. 9 As shown, it is a top view of its arrangement position, in which a rectangle represents a locust monitoring trap, and the specific number of devices can be determined according to actual usage.

[0116] The locust monitoring and trapping devices in Examples 1 and 2 are both equipped with a monitoring part. When monitoring is not needed, the monitoring part can be turned off and the device is only used as a locust trap.
