Description

Technical Field

[0001] This invention relates to the field of pest control technology, specifically to a trapping device and method based on biological pest control. Background Technology

[0002] Pest and disease control is a human-made means to reduce or prevent the harm of pathogenic microorganisms and pests to crops or livestock. It can generally be divided into chemical control using chemical substances such as insecticides and physical control using physical energy such as light or rays or building barriers.

[0003] Currently, forestry pest and disease control generally uses trapping lamps or a large number of pest and disease control boxes, but there are still some drawbacks. For example, trapping lamps use conductive metal wire covers to electrocute the attracted pests, but many of the dead pests killed by the electric shock will stick to the metal wire cover, requiring constant cleaning, otherwise it will affect the later killing effect. Another example is the use of sticky sheets to treat pests, which requires frequent replacement of the sticky sheets. Summary of the Invention

[0004] The purpose of this invention is to provide a trapping device and method for biological control of pests. By utilizing the characteristics of the rewetting adhesive tape, when the spraying component sprays liquid in a ring and acts on the coating area of ​​the rewetting adhesive tape, it can maintain its stickiness. Under the attraction of the trapping agent, the rewetting adhesive tape can be continuously unrolled to achieve fluidity and replaceability of the adhesion area, thus avoiding the adverse effects of the existing method that requires constant replacement of adhesive sheets.

The attractant at the bottom of the water collection tank is replaced with an insecticide.

[0014] A method for trapping pests based on biological control, applied to the aforementioned trapping device based on biological control of pests, the trapping method comprising:

[0015] S1: The rewetting adhesive tape can be unwound separately by two rotatable take-up rollers, and the ends of the rewetting adhesive tape pass through the through slots opened at the top of the drive ring and are attached to the periphery of both sides of the drive ring and droop on both sides of the drive ring, so that the rewetting adhesive tape forms two semi-circular sections with a coating layer on the outer side.

[0016] S2: With the trapping channel groove mechanism and spraying component set on its outer periphery, the trapping channel groove mechanism is driven to close completely, and the spraying component sprays liquid in a ring and acts on the coating area where the rewetting adhesive tape is located, so that it can maintain its stickiness.

[0017] S3: Adjust the size of the trapping channel mechanism to ensure that the corresponding pests can enter. Under the influence of the surface stickiness of the wet adhesive tape and the attraction of the trap, pests can be attracted to approach and adhere.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention utilizes the characteristics of rewetting adhesive tape. When the spraying component sprays liquid in a ring and acts on the coating area where the rewetting adhesive tape is located, it can maintain its adhesion. Under the attraction of the attractant, the fluidity of the adhesion area and the replaceability are achieved by continuously unwinding the rewetting adhesive tape, thus avoiding the adverse effects of the existing adhesive sheets that need to be constantly replaced.

[0020] 2. The design of the mobile vehicle body facilitates the movement of the device. The vehicle frame consists of a mixing box and a main box, which combines pest trapping with basic fertilizer. That is, the wetted adhesive tape with pest corpses is cut, stirred and mixed with the basic fertilizer in the fertilizer conversion device, realizing the green treatment of the wetted adhesive tape.

[0021] 3. When the two main boxes installed via the mounting plate can be replaced with inner sleeves and insect-attracting modules, different pest control methods can be implemented in conjunction with the aforementioned trapping channel mechanism and spraying components.

[0022] 4. As an implementation method for pest control, a sealed structure in the form of a cylinder is formed by several baffles. When the spraying component sprays the insecticide, the pests trapped in the area of ​​the baffles are killed. The trapping channel mechanism is closed just before it closes, which reduces the possibility of the pests flying away. On the other hand, when the trapping channel mechanism is completely closed, the corresponding insect-attracting module and the outer sleeve channel are closed, which avoids the adverse effects caused by the sprayed agent entering the inner sleeve and improves the service life of the trapping agent.

[0023] 5. As an implementation method of biological control, when the inner sleeve is equipped with a built-in trap or a micro-attracting lamp, the spraying component is connected to a fungal breeding box. After the trapping channel mechanism is closed, fungal spores are released into the area formed by the baffle plate to infect pests and continue to reproduce. When the number of pests carrying fungi is large, the trapping channel mechanism is opened to release the fungi-carrying pests into the environment and infect other pests.

Detailed Implementation

[0035] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Please see Figures 1 to 10 The present invention preferably provides the following technical solution: a pest trapping device based on biological pest control, comprising: a mobile vehicle body, and pest trapping components disposed on the mobile vehicle body; the pest trapping components include two sets of frame assemblies, a transmission ring 12 disposed between the two sets of frame assemblies, the transmission ring 12 being cylindrical and having a through groove at its top; and two rotatable take-up rollers 17 disposed inside the transmission ring 12; each of the two take-up rollers 17 is provided with a rewetting adhesive strip 18, the ends of the two rewetting adhesive strips 18 away from the take-up rollers 17 passing through the through groove at the top of the transmission ring 12. The rewetting adhesive tape 18 is attached to the outer walls of two semi-circular sections formed by the grooves along both sides of the transmission ring 12, forming a trapping adhesion area. It also includes a trapping channel groove mechanism disposed on the outer periphery of the transmission ring 12, which can adjust the opening and closing size of the channel. It also includes a spraying component disposed on the trapping channel groove mechanism. When the channel where the trapping channel groove mechanism is located is completely closed and forms a complete circle, the spraying component sprays liquid in a ring and acts on the outer walls of the two semi-circular sections formed by the rewetting adhesive tape 18, triggering the self-adhesion of the rewetting adhesive tape 18.

[0038] In this embodiment, combined with Figure 1 , 2 3, 6 and Figure 7 As shown, in this application, the processing technology of the rewetting adhesive tape 18 is a rewetting kraft paper tape, which is made of kraft paper as the base material and coated with modified chemical starch-based rewetting adhesive. The adhesive surface needs to be wetted with water to become sticky.

[0039] Specifically, such as Figure 6As shown, two rotatable take-up rollers 17 can unwind the rewetting adhesive tape 18 respectively. The ends of the rewetting adhesive tape 18 pass through the slots opened at the top of the drive ring 12 and adhere to the periphery of both sides of the drive ring 12, dangling on both sides of the drive ring 12, so that the rewetting adhesive tape 18 forms two semi-circular sections. The outer surface is coated, and its outer periphery is provided with a trapping channel groove mechanism and a spraying assembly. Before use, the rewetting adhesive tape 18 is unwound to cover the circumference of the drive ring 12. Then, the trapping channel groove mechanism is driven to fully close, and the spraying assembly is controlled to spray liquid, preferably... The mixture of water and attractant maintains its stickiness when the spraying component sprays the liquid in a ring and acts on the coating area of ​​the rewettable adhesive tape 18. At this time, the size of the channel of the trapping channel mechanism can be adjusted to ensure that the corresponding pests can enter. Under the adhesiveness of the surface of the rewettable adhesive tape 18 and the attraction of the attractant, pests can be attracted to approach and adhere. This design, by continuously unwinding the rewettable adhesive tape 18, combined with the trapping channel mechanism and the design of the spraying component spraying liquid, achieves fluidity and replaceability of the adhesion area, avoiding the adverse effects of the existing need to constantly replace the adhesive sheet.

[0040] Furthermore, two auxiliary rollers 20 located below the drive ring 12 are positioned between the frame components and are used for the drive limiting of the rewetting adhesive tapes 18 on both sides, so that the corresponding rewetting adhesive tapes 18 can be better attached to the periphery of the drive ring 12.

[0041] Furthermore, the mobile vehicle body includes a frame and wheels 5 mounted on the frame for driving the frame to move; the frame consists of a main body box 7 and a mixing box 4, the main body box 7 is used to receive the pest trapping components, and the mixing box 4 is equipped with a fertilizer conversion device.

[0042] This design, through the design of a mobile vehicle, facilitates the movement of the device. The vehicle frame consists of a mixing box 4 and a main body box 7, which combines pest trapping with basic fertilizer. Specifically, the rewetting adhesive tape 18, which adheres to the corpses of pests, is cut, stirred and mixed with the basic fertilizer in the fertilizer conversion device, achieving green treatment of the rewetting adhesive tape 18. At the same time, during the movement of the mobile vehicle, the converted fertilizer is distributed and scattered on the soil, achieving the soil fertilization effect.

[0043] Furthermore, each frame assembly includes a support plate 6 and a mounting component disposed inside the support plate 6, on which a mounting plate 23 is fixedly mounted for rotatably mounting two take-up rollers 17; and a meshing transmission mechanism disposed in one of the frame assemblies for driving the two take-up rollers 17 to rotate in opposite directions and unwind; the meshing transmission mechanism includes two connecting shafts, which are respectively connected to the two take-up rollers 17, and transmission teeth 25 disposed on the two connecting shafts and meshing with each other, and also includes a first motor 24 fixedly mounted on the support plate 6 for driving one of the transmission teeth 25 to rotate.

[0044] By setting frame components, such as Figure 1 As shown, when the first motor 24 is working, it can drive the two transmission gears 25 to mesh and rotate, thus engaging... Figure 6 As shown, both take-up rollers 17 unwind the rewetted adhesive tape 18. Specifically, the rotation is counterclockwise on the left and clockwise on the right. The driving method is controlled by the central processing module. Preferably, the diameter of the take-up roller 17 is half the diameter of the transmission ring 12. That is, one revolution of the take-up roller 17 is equal to the circumference of the semicircle of the transmission ring 12. In other words, the unwinding length of the rewetted adhesive tape 18 just covers the semicircular section formed by the previous rewetted adhesive tape 18, thereby realizing the replacement of the trapping and adhesion area.

[0045] Example 2

[0046] In another embodiment of the present invention, the trapping channel mechanism includes a mounting ring 11 and several through holes on the mounting ring 11. Each through hole is fixedly connected to a baffle plate 10 by a first pin. Each baffle plate 10 has a notch at its inner end, which allows adjacent baffle plates 10 to overlap and form a complete circle. A sealing ring 16 is fixedly connected to the mounting ring 11, and the inner ring of the sealing ring 16 extends into the outer ring of the transmission ring 12. Several linkage transmission components are provided between the trapping channel mechanism and the transmission ring 12 to drive the trapping channel mechanism to adjust the size of the channel opening and closing. An image recognition module is distributed inside the several baffle plates 10 to connect with the central processing module to acquire images of pests in the trapping and adhesion area, upload them to the central processing module, identify the number of pests in the images, and calculate the pest density based on the detection data. When the pest density is greater than a set value, the rewetting adhesive belt 18 containing the two take-up rollers 17 is driven to unwind.

[0047] In this embodiment, the trapping channel groove mechanism is configured such as... Figure 6 and 7As shown, the baffle plate 10 is fixedly connected by the first pin, and the inner end of the baffle plate 10 is provided with a notch or groove, which can overlap each other to form a complete circle. The mounting ring 11 serves as the mounting platform for the baffle plate 10. Under the action of several linkage transmission components, when the transmission ring 12 rotates back and forth relative to the mounting ring 11, it can drive the baffle plate 10 at the corresponding position to deflect synchronously in the same direction. Specifically, as shown... Figure 6 As shown, when the first pin shaft where the baffle plate 10 is located rotates counterclockwise, the outer ends of several baffle plates 10 approach each other, which is a gradually closed state. When the first pin shaft rotates clockwise, the outer ends of several baffle plates 10 move away from each other, which is a gradually open state. This design forms a complete cylindrical cover structure when the baffle plates 10 are completely closed. With the spraying assembly, the trapping area where the transmission ring 12 is located can be sprayed in a closed manner.

[0048] Image recognition module and central processing module are existing mature technologies for the identification and processing of pest density. Specifically, refer to the pest density monitoring system and monitoring method with application number CN202210763089.1.

[0049] Furthermore, each linkage transmission assembly includes a first connecting rod 13 and a second connecting rod 14. The near ends of the first connecting rod 13 and the second connecting rod 14 are rotatably connected via a second pin. The end of the first connecting rod 13 away from the second connecting rod 14 is fixedly connected to the first pin where the baffle plate 10 is located. The end of the second connecting rod 14 away from the first connecting rod 13 is rotatably connected via a third pin transmission ring 12. When the transmission ring 12 rotates back and forth, it drives several baffle plates 10 to deflect back and forth, thereby adjusting the size of the channel opening and closing. It also includes deflection transmission assemblies on the two sets of frame assemblies, used to drive the transmission... The rotating ring 12 deflects back and forth; the deflection transmission assembly includes a drive disk 9, which is connected to the inner ring of the transmission ring 12, and the drive disk 9 has a through hole in the middle for the mounting plate 23 to pass through, and telescopic rod structures respectively set at both ends of the drive disk 9 for driving the drive disk 9 to deflect back and forth. Each telescopic rod structure includes a connector 29, which is rotatably connected to the inner wall of the support plate 6 through a fourth pin, and a first electric telescopic rod 28 set on the connector 29. The first electric telescopic rod 28 has a telescopic rod part 27 inside, and the rod part 27 is rotatably connected to the corresponding end of the drive disk 9 through a fifth pin.

[0050] In the structure of the linkage transmission assembly, since one end of the first connecting rod 13 is fixedly connected to the first pin, the installation angle between the first connecting rod 13 and the baffle plate 10 is always kept constant. This, combined with the deflection transmission assembly, specifically, as shown... Figure 2 , 3In diagrams 4, 6, and 7, the drive disc 9 is in a horizontal position, meaning the telescopic rod structures on both sides are of equal length. Since the telescopic rod structure comprises the first electric telescopic rod 28 and its internal rod portion 27, it is connected to the bottom connecting piece 29 via rotation. Figure 2 Combination Figure 6 To illustrate, when the left rod 27 extends and the right rod 27 shortens, the corresponding drive disc 9 drives the transmission ring 12 to rotate clockwise. Similarly, when the left rod 27 shortens and the right rod 27 extends, the corresponding drive disc 9 drives the transmission ring 12 to rotate counterclockwise. Figure 6 When the transmission ring 12 deflects clockwise, the second connecting rod 14, under the connection of the third pin and the first connecting rod 13, moves closer to the second pin, causing the first connecting rod 13 to move closer to the pin. This causes the baffle plate 10, where the first pin is located, to deflect counterclockwise, thus adjusting the channel size or closing it to form a complete circle. Similarly, when the transmission ring 12 deflects counterclockwise, the second connecting rod 14, under the connection of the third pin and the first connecting rod 13, moves closer to the second pin, causing the first connecting rod 13 to move closer to the pin. This causes the baffle plate 10 to deflect clockwise, thus opening the channel.

[0051] Example 3

[0052] In another embodiment of the present invention, the spraying assembly includes a connecting pipe 8 disposed on a support plate 6, one end of which extends to the inner side of the support plate 6 and is connected to an annular rigid pipe 19; and a water outlet pipe 22 disposed in the middle of the inner side of each baffle plate 10, with a plurality of nozzles linearly distributed on the water outlet pipe 22; the annular rigid pipe 19 is used to fix and install the mounting ring 11 and is connected to the plurality of water outlet pipes 22 through a conduit; and a water collection tank 2 fixed on the support plate 6 for collecting rainwater in the environment, and a filter screen 15 disposed inside the water collection tank 2 for filtering rainwater to remove sludge, and an attractant may be disposed at the bottom of the water collection tank 2, which is sprayed with water onto the outer wall of the two semi-circular sections formed by the rewetting adhesive strip 18, and a water pump disposed at the bottom of the water collection tank 2, with the output end of the water pump connected to the connecting pipe 8 at the bottom.

[0053] In this embodiment, when used in conjunction with the above-mentioned trapping channel mechanism, when the baffle plate 10 is in a fully closed or even circular state, the central processing module controls the water pump to work. Under the connection between the connecting pipe 8 and the annular rigid pipe 19, the nozzle where the water outlet pipe 22 is located sprays liquid in an annular shape and distributes it evenly on the rewetting adhesive strip 18. In the above embodiment, the sprayed liquid is a mixture of attractant and water. The water can trigger the stickiness of the rewetting adhesive strip 18, and the attractant can attract pests.

The pulling mechanism includes a first conveying roller assembly and a second conveying roller assembly respectively disposed on the upper and lower sides of the rewetting adhesive tape 18. The first conveying roller assembly includes two sets of limiting plates 21, each set of limiting plates 21 being an isosceles trapezoidal structure, and an electric slide rail 38 disposed on the top of the limiting plate 21. An electric slider 39 is disposed inside the electric slide rail 38, and a first connecting block 40 extends from the side wall of the electric slider 39. A movable column 41 is installed through the middle of the connecting block 40. A second connecting block 43 is connected to the bottom of the movable column 41. A first spring 42 is provided on the outer wall of the movable column 41 between the second connecting block 43 and the first connecting block 40, and a first pressure strip 37 is arranged transversely between the two second connecting blocks 43.

A second spring 45 is connected between each mounting block 47 and the end of the mounting frame 46, and a second pressure strip 48 is connected between the connecting rod telescopic mounting blocks 47.

[0056] In this embodiment, as an auxiliary treatment of the rewetted adhesive strip 18 containing the corpses of adhering pests, a pulling mechanism is provided, such as... Figure 1 , 3 As shown, the pulling mechanism can intermittently pull the rewetting adhesive belt 18 into the fertilizer conversion device. The specific structure is as follows: Figure 8 , 9 As shown, the electric slide rail 38 and the electric slider 39 are existing mature technologies. The electric slider 39 can reciprocate linearly inside the electric slide rail 38. Under the isosceles trapezoidal structure of the limiting plate 21, it can...

The surfaces of the first pressure strip 37 and the second pressure strip 48 are provided with rubber damping layers. The pulling direction is from left to right. The natural elongation length of the second spring 45 is located at the leftmost side of the horizontal section of the limiting plate 21. When the electric slider 39 runs from left to right on the electric slide rail 38, the corresponding limiting post 44 moves along the isosceles trapezoidal structure side of the limiting plate 21 until it reaches the leftmost side of the horizontal section of the limiting plate 21. Under the action of the inclined surface on the left side of the limiting plate 21, the first pressure strip 37 moves down to the lowest position and connects with the lower second spring 45. When the pressure strip 48 comes into contact, under the pressure of the first pressure strip 37 and the second pressure strip 48, the two pressure strips can clamp the two rewetting adhesive strips 18. As the electric slider 39 continues to move to the right, the first pressure strip 37 and the second pressure strip 48 clamp the rewetting adhesive strip 18 and pull it to move, compressing the second spring 45 below. When it reaches the inclined surface on the right side of the limiting plate 21, the first pressure strip 37 moves upward under the elastic force of the first spring 42. At this time, the second pressure strip 48 loses the pressure of the first pressure strip 37 above. Under the elastic force of the second spring 45, the second pressure strip 48 returns to its initial position, which facilitates the next pulling process.

A first channel groove 30 and a second channel groove 35 are respectively disposed at the top and bottom of the mixing tank 4. An installation shaft 32 is rotatably installed inside the mixing tank 4. A first channel plate 31 and a second channel plate 34 are respectively fixed to the top and bottom of the installation shaft 32. When the first channel plate 31 coincides with the through hole of the first channel groove 30, it is used for the intermittent falling of the base fertilizer in the storage tank 3. When the second channel plate 34 coincides with the second channel groove 35, it is used for the rotation... The process includes: discharge of the replaced fertilizer; a cutter 33 is provided in the middle of the mounting shaft 32 for cutting, crushing and mixing the adhering insect rewetting adhesive tape 18 with the base fertilizer; a second motor 36 is provided at the bottom of the mixing box 4, extending into the mixing box 4 and connected to the mounting shaft 32; and a baffle assembly is provided at the bottom of the mixing box 4, which includes two second electric telescopic rods 55 and a connecting frame 54 provided at the output end of the two second electric telescopic rods 55. A retaining ring 53 is fixed on the connecting frame 54 for controlling the discharge of the replaced fertilizer in the second channel groove 35.

[0059] In this embodiment, the rewetted adhesive tape 18 containing the corpses of adhering pests is further processed, such as... Figure 1 , 3As shown in Figure 5, under the action of the pulling mechanism, the rewetting adhesive tape 18 adhering to the insect corpses continuously enters the mixing box 4, which can periodically drive the second motor 36 to work, driving the first channel plate 31, the cutter 33, and the second channel plate 34 where the mounting shaft 32 is located to rotate. The cooperation between the first channel groove 30 and the first channel plate 31, during the continuous rotation of the first channel plate 31, when the first channel groove 30 coincides with the through hole of the first channel plate 31, can realize the addition of basic fertilizer once. During the continuous rotation of the cutter 33, the rewetting adhesive tape 18 and the basic fertilizer inside the mixing box 4 can be cut and mixed. When the baffle component at the bottom of the mixing box 4 closes the second channel groove 35, the second motor 36 only completes the cutting and mixing process to ensure the mixing and forming. When the second motor 36 is driven by the second electric telescopic rod 55 to disengage from the second channel groove 35, the intermittent discharge process can be realized.

[0060] Example 6

[0061] In another embodiment of the present invention, the two winding rollers 17 mounted on the mounting plate 23 can be replaced with an inner sleeve 51 and an insect-attracting module 52. The inner sleeve 51 is fitted inside the insect-attracting module 52, and an outer sleeve 50 is connected to the inner side of the transmission ring 12. Both the outer sleeve 50 and the insect-attracting module 52 have through holes. When the two overlap, the inner sleeve 51 releases insect-attracting factors, and the spacing of the through holes on the outer sleeve 50 is set to meet the requirements. When the transmission ring 12 deflects and drives the baffle plate 10 to form a complete circle and close, the through holes on the outer sleeve 50 and the through holes on the insect-attracting module 52 do not overlap. The attractant set at the bottom of the water collection tank 2 is replaced with an insecticide.

[0062] There are various methods of trapping pests for biological control. Examples 1-5 use adhesive tape to trap pests. In this example, such as... Figure 10 Through the design of the inner sleeve 51, the insect-attracting module 52 and the outer sleeve 50, combined with the above-mentioned trapping channel mechanism and spraying components, different pest control methods can be carried out.

[0063] As a method of pest control:

[0064] When the inner sleeve 51 contains a built-in attractant, and the spraying assembly sprays the insecticide in a ring, when the trapping channel mechanism opens and closes at a certain angle, the corresponding transmission ring 12 drives the outer sleeve 50 to rotate so that its through hole coincides with the through hole of the insect-attracting module 52. At this time, the attractant inside the inner sleeve 51 releases attractant factors, which are dispersed through the connected through holes, attracting pests into the baffle plate 10 and surrounding the outer sleeve 50. When the image recognition module collects an image of the pest density, and the set density value is reached, the central processing module receives a signal and controls the trapping channel mechanism to close. Several baffle plates 10 form a sealed structure in a cylindrical state, and when the spraying assembly sprays the insecticide, the insects trapped in the baffle plates are trapped in the baffle plates. In the 10-area pest control, preferably, when the trapping channel mechanism is about to close, i.e. the channel is not large enough for the pests to fly out, the outer sleeve 50 rotates so that its through hole is gradually separated from the through hole of the insect-attracting module 52, thereby closing the channel between the outer sleeve 50 and the insect-attracting module 52. This design has two advantages: firstly, the channel between the outer sleeve 50 and the insect-attracting module 52 closes only when the trapping channel mechanism is about to close, reducing the possibility of the pests flying away; secondly, when the trapping channel mechanism is completely closed, the corresponding channel between the insect-attracting module 52 and the outer sleeve 50 is closed, avoiding the adverse effects caused by the sprayed agent entering the inner sleeve 51, and improving the service life of the trapping agent.

[0065] The inner sleeve 51 can also be an insect-attracting lamp. When the outer sleeve 50 rotates, its through hole coincides with the through hole of the insect-attracting module 52, and the light is emitted to attract pests. When the trapping channel mechanism is completely closed to kill insects, the corresponding insect-attracting module 52 and the outer sleeve 50 channel are closed, which can prevent the sprayed agent from entering the inner sleeve 51.

[0066] As a method of biological control:

[0067] When the inner sleeve 51 is equipped with a built-in trap or a micro-infestation lamp, the spraying component is connected to a fungal breeding box. After the trapping channel mechanism is closed, fungal spores are released into the area formed by the baffle plate 10 to infect pests and continue to reproduce. When the number of fungi carried by pests is large, the trapping channel mechanism is opened to release the fungi-carrying pests into the environment, thereby infecting other pests and achieving the purpose of self-propagation. Through the application of fungal insecticide, the purpose of effective and continuous pest control is achieved. Specifically, the fungal spore control process can refer to a pest biological control integrated system with application number 201711358445.7.

[0068] Furthermore, the top of the support plate 6 is equipped with a solar panel 1 and a battery inside the device, both of which are existing mature technologies, forming a solar power supply module to improve the power supply of the device.

[0069] A method for trapping pests based on biological control, applied to the aforementioned trapping device based on biological control of pests, the trapping method comprising:

[0070] S1: The rewetting adhesive tape 18 can be unwound by two rotatable take-up rollers 17 respectively, and the ends of the rewetting adhesive tape 18 pass through the through slots opened at the top of the drive ring 12 and are attached to the periphery of both sides of the drive ring 12 and hang on both sides of the drive ring 12, so that the rewetting adhesive tape 18 forms two semi-circular sections with a coating layer on the outer side.

[0071] S2: With the trapping channel groove mechanism and spraying component set on its outer periphery, the trapping channel groove mechanism is driven to close completely, and the spraying component sprays liquid in a ring and acts on the coating area where the rewetting adhesive tape 18 is located, so that it can maintain its adhesion.

[0072] S3: Adjust the size of the trapping channel mechanism to ensure that the corresponding pests can enter. Under the surface stickiness of the rewetting adhesive tape 18 and the attraction of the trapping agent, the pests can be attracted to approach and adhere.

[0073] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
