Description

Technical Field

[0001] This invention relates to the field of insect trapping device technology, specifically to a thrips trapping device and trapping method. Background Technology

[0002] Thrips are an important agricultural pest with a very wide host range, including various vegetable crops such as those belonging to the Cucurbitaceae, Solanaceae, Brassicaceae, and Leguminosae families. These pests are characterized by their tiny size (usually only 1-2 mm in length), strong concealment (often inhabiting flowers, the undersides of young leaves, etc.), and high reproductive capacity, making their populations prone to outbreaks in a short period and seriously threatening agricultural production.

[0003] Based on thrips' attraction to specific odors and colors, blue sticky traps combined with attractants can be used for control. On one hand, the blue spectrum attracts adult thrips; on the other hand, spraying attractants onto the blue sticky traps enhances their effectiveness. Currently, in practice, attractants are manually added to the sticky traps periodically; this requires multiple, unscheduled additions, making the process cumbersome. Furthermore, if the added attractant does not evaporate quickly and diffuse effectively into the air, it will reduce the thrips' sensitivity to the attractant, thus affecting the trapping effect of the blue sticky traps. Summary of the Invention

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the prior art, and to provide a thrips trapping device and method.

[0005] According to a first aspect of the present invention, a thrips trapping device is provided, comprising: Blue insect-attracting board, the blue insect-attracting board being coated with sticky insect glue; A first support plate has hooks on its upper surface, which are used to hook the four corners of the blue insect-attracting board so that the blue insect-attracting board is bent downwards. The dripping mechanism includes a dripping tube with outlet holes spaced apart. The dripping tube is positioned directly above the blue insect-attracting board, and one end of the dripping tube is connected to a dripping tank. The dripping tube is used to drip thrips attractant from the dripping tank onto the blue insect-attracting board. A blower mechanism is used to intermittently blow air onto the surface of a blue insect-attracting board, so that the thrips attractant dripped onto the blue insect-attracting board evaporates more quickly and diffuses into the surrounding air.

[0006] A further embodiment is that the blower mechanism includes fan blades located directly above the blue insect-attracting board; the fan blades are driven to rotate by a rotary motor; the dripping tank is equipped with a first liquid level sensor and a second liquid level sensor; the dripping tank is connected to the storage tank via a connecting pipe; when the liquid level in the dripping tank is lower than the first liquid level sensor, the solenoid valve and the rotary motor on the connecting pipe are opened; when the liquid level in the dripping tank is higher than the second liquid level sensor, the solenoid valve and the rotary motor on the connecting pipe are closed.

[0007] A further embodiment is that the output end of the rotary motor is fixedly connected to a rotating shaft, and several worm gears are installed at intervals on the rotating shaft. The blue insect-attracting plates of the fan blades are spaced apart along the length direction, and the fan blades are installed at the bottom end of the worm. The worm gears correspond one-to-one with the worm and are meshed together.

[0008] A further embodiment involves mounting the dripping mechanism on a second support plate, which has an annular groove. A fan shroud is slidably fitted onto the annular groove, and the fan shroud moves up and down under the drive of an electric telescopic rod. When the liquid level in the dripping tank is lower than the first liquid level sensor, the electric telescopic rod extends so that the bottom of the fan shroud approaches the blue insect-attracting board. When the liquid level in the dripping tank is higher than the second liquid level sensor, the electric telescopic rod retracts so that the bottom of the fan shroud moves away from the blue insect-attracting board.

[0009] A further embodiment is that the wind shield has a rectangular cross-section and is composed of two first side plates and two second side plates. The first side plates correspond to the length direction of the blue insect-attracting board, and the second side plates correspond to the width direction of the blue insect-attracting board. The bottom height of the first side plate is higher than that of the second side plate, so that when the bottom of the first side plate is close to the blue insect-attracting board, the bottom of the second side plate is close to the first support plate.

[0010] A further embodiment is that the inner wall of the fan shroud is provided with a squeezing plate, the dripping tubes are respectively located on both sides of the fan blades, and the outer wall of the dripping tubes is rotatably connected to a guide plate. The dripping tubes are connected to a second support plate through a fixing rod. The upper surface of the guide plate is connected to one end of a spring, and the other end of the spring is connected to the fixing rod. When the fan shroud moves downward, the squeezing plate is used to squeeze the guide plate so that the guide plate is tilted downward.

[0011] A further option is that the air guide plate is a downwardly curved arc plate.

[0012] A further embodiment is that the bottom of the dripping tank is provided with a drain trough, one end of which is connected to the dripping pipe.

[0013] A further embodiment is that the upper surface of the blue insect-attracting board is provided with upwardly protruding thin plates at intervals, and the thin plates extend along the width direction of the blue insect-attracting board.

[0014] According to a second aspect of the present invention, a method for trapping thrips is provided, employing the trapping device as described above, characterized in that it specifically includes the following steps: Apply sticky insect glue to the top and bottom surfaces of the blue insect-attracting board; Cut through holes at the four corners of the blue insect-attracting board, and pass the hooks set on the upper surface of the first support board through the through holes in the blue insect-attracting board so that the blue insect-attracting board is fixed to the first support board in a downward bending state. The thrips attractant in the drip box is dripped onto the blue insect-attracting board through the outlet hole on the drip tube. By intermittently blowing air onto the surface of the blue insect-attracting board using a blower mechanism, the thrips attractant dripping onto the blue insect-attracting board is accelerated to evaporate and diffuse into the surrounding air.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention enables the blower mechanism to flexibly switch between working and non-working states through the cooperation of the first liquid level sensor, the second liquid level sensor, the solenoid valve and the rotary motor; when the blower mechanism is in the non-working state, it can ensure that tiny thrips can fly smoothly to the blue insect-attracting board without interference. When the blower mechanism is working, it can accelerate the evaporation of the thrips attractant dripped onto the blue insect-attracting board and promote its rapid diffusion into the surrounding air, thereby attracting thrips in the environment more effectively; (2) When the wind cover is driven downward by the electric telescopic rod, the wind cover can cover the blue insect-attracting board and the blower. The airflow will be discharged through the gap between the bottom of the wind cover and the edge of the blue insect-attracting board, causing the airflow to blow along the surface of the blue insect-attracting board. On the other hand, during the downward movement of the wind cover, the air guide plate is tilted downward. At this time, the air guide plate adapts to the curved state of the blue insect-attracting board, further causing the airflow to blow along the surface of the blue insect-attracting board, which is conducive to the accelerated evaporation of the attractant covering the entire surface of the blue insect-attracting board, thereby improving the overall evaporation effect of the attractant on the blue insect-attracting board. In addition, after the wind cover is driven upward by the electric telescopic rod, the wind cover no longer covers the blue insect-attracting board. On the other hand, the air guide plate will be in a horizontal state, so that the blue insect-attracting board will not be blocked in front, behind, left, or right. This is conducive to the thrips discovering the blue insect-attracting board through their visual system and being attracted by the blue insect-attracting board. Attached Figure Description

[0018] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figures 1-6This invention provides a thrips trapping device, including a support rod 1, the bottom of which is mounted on the ground. A first support plate 2 and a second support plate 3 are fixedly connected to the upper end of the support rod 1 via a connecting rod. A blue insect-attracting plate 4, made of plastic, is mounted on the first support plate 2, and both its upper and lower surfaces are coated with adhesive. Specifically, four hooks are provided on the upper surface of the first support plate 2. Through holes are made at the four corners of the blue insect-attracting plate 4. By passing the hooks through these holes, the blue insect-attracting plate 4 is fixed to the first support plate 2 in a downward-bending position, thus arching upwards relative to the first support plate 2. This allows the blue insect-attracting plate 4 to attract thrips from both its upper and lower surfaces, and then trap the thrips with the adhesive, achieving the purpose of trapping and killing them.

[0021] The second support plate 3 is equipped with a dripping mechanism, which includes a storage tank 9 and a dripping tank 10. The lower surface of the dripping tank 10 is mounted on the second support plate 3 via support legs. The storage tank 9 is used to store a mixture of attractant and slow-release agent. Preferably, the storage tank 9 can be equipped with a stirring mechanism to mix the attractant and slow-release agent evenly. The slow-release agent slows down the release of the attractant, reducing the amount of attractant needed. The storage tank 9 is connected to the dripping tank 10 via a connecting pipe 13. A solenoid valve is installed on the connecting pipe 13. After the solenoid valve is opened, the attractant in the storage tank 9 can be injected into the dripping tank 10. The bottom of the dripping tank 10 has a drain trough. One end of the drain trough is connected to a dripping pipe 14. The end of the dripping pipe 14 away from the drain trough passes through the second support plate 3 and extends along the length of the blue insect attractant plate 4. The dripping pipe 14 located below the second support plate 3 has spaced-apart outlet holes 141. Two drip tubes 14 are provided, which are located on both sides of the center of the blue insect-attracting plate 4. The outlet hole 141 is used to drip the attractant onto the center of the blue insect-attracting plate 4. Since the blue insect-attracting plate 4 is curved downward, the attractant can flow slowly downward along the surface of the blue insect-attracting plate 4, so that the attractant can evenly cover the entire upper surface of the blue insect-attracting plate 4. This helps all parts of the blue insect-attracting plate 4 to fully play the role of attracting and killing thrips.

[0022] Please see Figure 2 , Figure 4 and Figure 5The second support plate 3 is also equipped with a blower mechanism, which is used to intermittently blow air onto the surface of the blue insect-attracting board 4, so that the thrips attractant dripping onto the blue insect-attracting board 4 evaporates faster and diffuses into the surrounding air; and because the blower mechanism blows air onto the surface of the blue insect-attracting board 4 intermittently, tiny thrips can fly onto the blue insect-attracting board 4 when the blower mechanism is not working. Specifically, the blower mechanism includes a rotary motor 22, which is mounted on the second support plate 3 via a third support plate 27. The output end of the rotary motor 22 is fixedly connected to a rotating shaft 23, and a plurality of worm gears 24 are installed at intervals on the rotating shaft 23. The worm gears 24 correspond one-to-one with the worm 25 and are meshed with each other. The worm 25 is rotatably connected to the second support plate 3, and the bottom end of the worm 25 passes through the second support plate 3 and is fixedly connected to a fan blade 26, which is spaced along the length of the blue insect-attracting board 4. When the rotary motor 22 is started, the rotary motor 22 drives all the fan blades 26 to rotate simultaneously through the cooperation of the worm gear 24 and the worm 25, so that the fan blades 26 blow air onto the surface of the blue insect-attracting board 4.

[0023] To achieve intermittent operation of the blower mechanism, a first liquid level sensor 11 and a second liquid level sensor 12 are installed inside the dripping tank 10. When the liquid level in the dripping tank 10 is lower than the first liquid level sensor 11, the solenoid valve on the connecting pipe 13 and the rotary motor 22 are opened. At this time, the storage tank 9 replenishes the attractant into the dripping tank 10, and the rotary motor 22 drives the fan blades 26 to rotate, causing the fan blades 26 to blow air onto the surface of the blue insect-attracting board 4. When the liquid level in the dripping tank 10 is higher than the second liquid level sensor 12, the solenoid valve on the connecting pipe 13 and the rotary motor 22 are closed. At this time, the storage tank 9 no longer replenishes the attractant into the dripping tank 10, and the attractant in the dripping tank 10 drips slowly downward through the outlet hole 141 on the dripping pipe 14 until the liquid level in the dripping tank 10 is lower than the first liquid level sensor 11. During the slow decrease of the liquid level in the dripping tank 10, the blower mechanism remains inactive to ensure that the tiny thrips can fly smoothly to the blue insect-attracting board 4 without interference. When the blower mechanism is activated, it accelerates the evaporation of the thrips attractant dripped onto the blue insect-attracting plate 4, causing it to rapidly diffuse into the surrounding air, thus more effectively attracting thrips in the environment. Furthermore, the solenoid valve on the connecting pipe 13 replenishes the attractant at a significantly faster rate than the liquid exiting through the outlet hole 141, allowing the liquid level in the drip tank 10 to rise more quickly to the height of the second liquid level sensor 12. Preferably, by controlling the replenishment rate of the drip tank 10 through the connecting pipe 13, each blower operation lasts approximately 2 minutes.

[0024] Please continue reading. Figure 2 , Figure 4 and Figure 5The second support plate 3 has an annular groove 19, which is rectangular. A wind shield 20 is slidably fitted onto the annular groove 19, and the wind shield 20 is also rectangular in cross-section. Guide rails 5 are fixedly connected to both ends of the upper surface of the second support plate 3, and the outer surface of the wind shield 20 is slidably fitted to the guide rails 5 via a slider 6. The top of the guide rails 5 is fixedly connected to the outer wall of the liquid storage tank 9 via a connecting plate 8. An electric telescopic rod 7 is installed on the lower surface of the connecting plate 8, and the output end of the electric telescopic rod 7 is connected to the slider 6. Therefore, when the electric telescopic rod 7 extends or retracts, it can drive the wind shield 20 to move up and down. Specifically, when the liquid level in the dripping tank 10 is lower than the first liquid level sensor 11, the electric telescopic rod 7 extends so that the bottom of the wind shield 20 is close to the blue insect attractant plate 4; when the liquid level in the dripping tank 10 is higher than the second liquid level sensor 12, the electric telescopic rod 7 retracts so that the bottom of the wind shield 20 is away from the blue insect attractant plate 4. Understandably, when the bottom of the fan shroud 20 is close to the blue insect-attracting plate 4, the fan shroud 20 covers both the blue insect-attracting plate 4 and the blower, with a certain gap between the bottom of the fan shroud 20 and the edge of the blue insect-attracting plate 4. When the fan blades 26 start and blow air onto the surface of the blue insect-attracting plate 4, the airflow will be discharged through the gap between the fan shroud 20 and the blue insect-attracting plate 4. Because the bottom of the fan shroud 20 is close to the surface of the blue insect-attracting plate 4, the airflow will blow along the surface of the blue insect-attracting plate 4, which is beneficial for accelerating the evaporation of the attractant covering the entire surface of the blue insect-attracting plate 4, thereby improving the overall evaporation effect of the attractant on the blue insect-attracting plate 4.

[0025] Preferably, the fan cover 20 consists of two first side plates 201 and two second side plates 202. The first side plates 201 correspond to the length direction of the blue insect-attracting plate 4, and the second side plates 202 correspond to the width direction of the blue insect-attracting plate 4. The bottom of the first side plate 201 is higher than the bottom of the second side plate 202, so that when the bottom of the first side plate 201 is close to the blue insect-attracting plate 4, the bottom of the second side plate 202 is close to the first support plate 2. Therefore, when the fan blades 26 start and blow air onto the surface of the blue insect-attracting plate 4, the fan cover 20 covers the front and rear ends of the blue insect-attracting plate 4, causing the airflow to be discharged from the left and right sides of the blue insect-attracting plate 4, which is beneficial for the airflow to blow along the surface of the blue insect-attracting plate 4.

[0026] Furthermore, the inner wall of the wind shield 20 is provided with a squeezing plate 21, and a guide plate 18 is rotatably connected to the outer wall of the dripping tube 14. The guide plate 18 is a downwardly curved arc plate. Specifically, one end of the guide plate 18 is connected to a circular tube sleeved on the outer surface of the dripping tube 14, allowing the guide plate 18 to rotate relative to the central axis of the dripping tube 14. A sleeve 15 is also sleeved on the outer surface of the dripping tube 14. The outer surface of the sleeve 15 is connected to the lower surface of the second support plate 3 through a fixing rod 16. The sleeve 15 and the fixing rod 16 serve to support the dripping tube 14. The upper surface of the guide plate 18 is connected to one end of a spring 17, and the other end of the spring 17 is connected to the fixing rod 16. When the electric telescopic rod 7 moves the fan cover 20 downwards, the squeezing plate 21 presses down on the air guide plate 18, causing the air guide plate 18 to tilt downwards. At this time, the air guide plate 18 adapts to the curved blue insect-attracting plate 4, allowing airflow to pass through the channel between the air guide plate 18 and the blue insect-attracting plate 4. This facilitates the airflow across the surface of the blue insect-attracting plate 4, further accelerating the evaporation of the attractant covering the entire surface of the blue insect-attracting plate 4, thereby improving the overall evaporation effect of the attractant on the blue insect-attracting plate 4. When the electric telescopic rod 7 moves the fan cover 20 upwards, the squeezing plate 21 no longer squeezes the air guide plate 18, and under the reset action of the spring 17, the air guide plate 18 returns to a horizontal state.

[0027] It should be noted that when the electric telescopic rod 7 drives the fan cover 20 downwards, on the one hand, the fan cover 20 can cover the blue insect-attracting board 4 and the blower, and the airflow will be discharged through the gap between the bottom of the fan cover 20 and the edge of the blue insect-attracting board 4, causing the airflow to blow along the surface of the blue insect-attracting board 4; on the other hand, during the downward movement of the fan cover 20, the air guide plate 18 is tilted downwards. At this time, the air guide plate 18 adapts to the curved state of the blue insect-attracting board 4, further causing the airflow to blow along the surface of the blue insect-attracting board 4, which is conducive to the accelerated evaporation of the attractant evenly covering the entire surface of the blue insect-attracting board 4, thereby improving the overall evaporation effect of the attractant on the blue insect-attracting board 4. In addition, when the electric telescopic rod 7 drives the fan cover 20 upwards, on the one hand, the fan cover 20 no longer covers the blue insect-attracting board 4; on the other hand, the air guide plate 18 will be in a horizontal state, so that the blue insect-attracting board 4 will not be blocked in front, behind, left, or right, which is conducive to the thrips discovering the blue insect-attracting board 4 through their visual system and being lured and killed by the blue insect-attracting board 4.

[0028] For preferred options, please refer to [link / reference]. Figure 7The blue insect-attracting board 4 has upwardly protruding thin sheets 401 spaced apart on its upper surface, and these sheets 401 extend along the width of the blue insect-attracting board 4. The sheets 401 are also coated with sticky insect glue, thereby increasing the trapping surface area of ​​the blue insect-attracting board 4 and enabling it to trap more thrips. Furthermore, the sheets 401 extending along the width of the blue insect-attracting board 4 do not obstruct the attractant dripping onto the surface of the blue insect-attracting board 4 from flowing slowly downwards.

[0029] The present invention also provides a method for trapping thrips, using the trapping device described above, specifically including the following steps: Apply insect-sticking glue to the upper and lower surfaces of the blue insect-attracting board 4; Cut through holes at the four corners of the blue insect-attracting board 4, and pass the hooks set on the upper surface of the first support plate 2 through the through holes opened on the blue insect-attracting board 4 so that the blue insect-attracting board 4 is fixed on the first support plate 2 in a downward bending state. Thrips attractant from the drip box 10 is dripped onto the blue insect trap 4 through the outlet hole 141 on the drip tube 14. By intermittently blowing air onto the surface of the blue insect-attracting board 4 using a blower mechanism, the thrips attractant dripping onto the blue insect-attracting board 4 is accelerated to evaporate and diffuse into the surrounding air.

[0030] Optionally, the step of intermittently blowing air onto the surface of the blue insect-attracting board 4 using a blower mechanism to accelerate the evaporation and diffusion of the thrips attractant dripping onto the blue insect-attracting board 4 into the surrounding air specifically includes: When the first liquid level sensor 11 detects that the liquid level in the dripping tank 10 is lower than the first preset liquid level, the solenoid valve on the connecting pipe 13 and the rotary motor 22 are opened. At this time, the liquid storage tank 9 replenishes the attractant into the drip tank 10, and at the same time, the rotating motor 22 drives the fan blade 26 to rotate, so that the fan blade 26 blows air onto the surface of the blue insect attractant board 4.

[0031] When the second liquid level sensor 12 detects that the liquid level in the dripping tank 10 is higher than the second preset liquid level, the solenoid valve on the connecting pipe 13 and the rotary motor 22 are closed. At this point, the storage tank 9 stops replenishing the attractant into the dripping tank 10. The attractant in the dripping tank 10 drips slowly down through the outlet hole 141 on the dripping tube 14 until the liquid level in the dripping tank 10 is lower than the first liquid level sensor 11 again. During the process of the liquid level in the dripping tank 10 decreasing, the blower mechanism remains inactive to ensure that the tiny thrips can fly smoothly to the blue insect-attracting board 4 without interference.

[0032] The step of opening the solenoid valve and rotary motor 22 on the connecting pipe 13 when the first liquid level sensor 11 detects that the liquid level in the dripping tank 10 is lower than the first preset liquid level further includes: When the first liquid level sensor 11 detects that the liquid level in the dripping tank 10 is lower than the first preset liquid level, The electric telescopic rod 7 is extended so that the bottom of the wind cover 20 is close to the edge of the blue insect-attracting board 4; and the air guide plate 18 is pressed down by the squeezing plate 21 so that the air guide plate 18 is tilted downward.

[0033] When the second liquid level sensor 12 detects that the liquid level in the dripping tank 10 is higher than the second preset liquid level, closing the solenoid valve on the connecting pipe 13 and the rotary motor 22 further includes: The electric telescopic rod 7 is retracted, causing the wind cover 20 to move upward and no longer press the air guide plate 18, so that the air guide plate 18 returns to a horizontal state under the reset action of the spring 17.

[0034] Understandably, when the electric telescopic rod 7 drives the fan cover 20 downwards, on the one hand, the fan cover 20 can cover the blue insect-attracting board 4 and the blower, and the airflow will be discharged through the gap between the bottom of the fan cover 20 and the edge of the blue insect-attracting board 4, causing the airflow to blow along the surface of the blue insect-attracting board 4; on the other hand, during the downward movement of the fan cover 20, the air guide plate 18 is tilted downwards. At this time, the air guide plate 18 adapts to the curved state of the blue insect-attracting board 4, further causing the airflow to blow along the surface of the blue insect-attracting board 4, which is conducive to the accelerated evaporation of the attractant evenly covering the entire surface of the blue insect-attracting board 4, thereby improving the overall evaporation effect of the attractant on the blue insect-attracting board 4. In addition, when the electric telescopic rod 7 drives the fan cover 20 upwards, on the one hand, the fan cover 20 no longer covers the blue insect-attracting board 4; on the other hand, the air guide plate 18 will be in a horizontal state, so that the blue insect-attracting board 4 will not be blocked in front, behind, left, or right, which is conducive to the thrips discovering the blue insect-attracting board 4 through the visual system and being attracted by the blue insect-attracting board 4.

The dripping mechanism is mounted on the second support plate, which has an annular groove. A fan shroud slides on the annular groove and moves up and down under the drive of an electric telescopic rod. When the liquid level in the dripping tank is lower than the first liquid level sensor, the electric telescopic rod extends so that the bottom of the fan shroud is close to the blue insect-attracting board. When the liquid level in the dripping tank is higher than the second liquid level sensor, the electric telescopic rod retracts so that the bottom of the fan shroud is away from the blue insect-attracting board. The inner wall of the fan shroud is equipped with a squeezing plate, and drip tubes are located on both sides of the fan blades. A guide plate is rotatably connected to the outer wall of the drip tubes. The drip tubes are connected to the second support plate through a fixed rod. The upper surface of the guide plate is connected to one end of a spring, and the other end of the spring is connected to the fixed rod. When the fan shroud moves downward, the squeezing plate is used to squeeze the guide plate so that the guide plate is tilted downward.

2. The thrips trapping device according to claim 1, characterized in that: The output end of the rotary motor is fixedly connected to a rotating shaft, and several worm gears are installed at intervals on the rotating shaft. The fan blades are arranged at intervals along the length of the blue insect-attracting plate and are installed at the bottom of the worm. The worm gears correspond one-to-one with the worm and are meshed together.

3. A thrips trapping device according to claim 1, characterized in that: The wind shield has a rectangular cross-section and consists of two first side plates and two second side plates. The first side plates correspond to the length direction of the blue insect-attracting board, and the second side plates correspond to the width direction of the blue insect-attracting board. The bottom height of the first side plate is higher than the bottom height of the second side plate, so that when the bottom of the first side plate is close to the blue insect-attracting board, the bottom of the second side plate is close to the first support plate.

4. The thrips trapping device according to claim 1, characterized in that: The air guide plate is a downward-curved arc-shaped plate.

5. A thrips trapping device according to claim 1, characterized in that: The bottom of the dripping tank is provided with a draining groove, one end of which is connected to the dripping pipe.

6. A thrips trapping device according to claim 1, characterized in that: The upper surface of the blue insect-attracting board is provided with upwardly protruding thin plates at intervals, and the thin plates extend along the width direction of the blue insect-attracting board.

7. A method for trapping thrips, employing the trapping device as described in any one of claims 1-6, characterized in that: Specifically, the following steps are included: Apply sticky insect glue to the top and bottom surfaces of the blue insect-attracting board; Cut through holes at the four corners of the blue insect-attracting board, and pass the hooks set on the upper surface of the first support board through the through holes in the blue insect-attracting board so that the blue insect-attracting board is fixed to the first support board in a downward bending state. The thrips attractant in the drip box is dripped onto the blue insect-attracting board through the outlet hole on the drip tube. By intermittently blowing air onto the surface of the blue insect-attracting board using a blower mechanism, the thrips attractant dripping onto the blue insect-attracting board is accelerated to evaporate and diffuse into the surrounding air.
