Description

Technical Field

[0001] This invention relates to the field of pest control technology, specifically to a thrips trapping device based on lotus root cultivation. Background Technology

[0002] Thrips feed on tender plant tissues with their rasping-sucking mouthparts, causing silvery-gray spots and curling deformities on leaves, and scarring or corking on the fruit surface. For example, when western flower thrips (Frankliniella occidentalis) infests tomatoes, the fruit surface develops "crater"-like depressions, reducing the marketable yield by more than 70%. In the floriculture industry, thrips feeding on orchid petals causes irreversible brown spots, directly affecting export quality. Furthermore, thrips are major vectors for more than 20 plant viruses, including Tomato Spotted Wilt Virus (TSWV) and Impatiens Necrotic Spot Virus (INSV), and indirect losses from viral diseases are typically 3-5 times greater than direct damage.

[0003] Thrips are tiny (1-2 mm) piercing-sucking pests commonly found in lotus root cultivation. Adults and nymphs primarily feed on the sap of tender tissues such as floating leaves, upright leaves, and young buds. Damage can be categorized into direct damage and indirect induction of diseases, ultimately affecting yield and quality.

[0004] Direct harm: Thrips burrow into the underside of leaves or into the crevices of leaf veins, causing pinpoint chlorotic spots on the leaves, which later merge into yellow patches. In severe cases, the leaves curl, dry out, and fall off. This significantly reduces the photosynthetic efficiency of the leaves, leading to insufficient nutrient production by the plant, affecting tillering, stem growth, and the enlargement of underground rhizomes, directly resulting in a decrease in yield.

[0005] Indirect harm: The tiny wounds left by piercing and sucking can easily become entry points for fungi and bacteria, inducing diseases such as anthracnose (brown circular sunken spots) and leaf spot (irregular yellowish-brown halo spots). Diseases can further damage leaves, creating a vicious cycle of "insect pests → wounds → diseases," accelerating plant weakness, and the spread of diseases is even faster in hot and humid environments.

[0006] Generally, thrips thrive in hot, dry environments and typically break out during the summer (June-August) when lotus leaves are in full bloom, causing more severe damage, especially in fields with shallow water levels and good ventilation and light penetration. Existing thrips traps (such as single-suspension sticky traps and fixed pheromone traps) are mostly hung along field edges or placed on the ground (for example, a thrips trapping device disclosed in patent number CN223125674U), and their design is generally suited to open field edges. However, lotus fields often have a certain planting area, with dense plants in the central area, where floating leaves and upright leaves grow interspersed, forming a dense shading layer. The color-attracting signals (such as blue light) and odor signals (such as pheromones) of traditional field-edge trapping devices decay rapidly under the obstruction of the plants, making it difficult to effectively spread to the central part of the field. At the same time, the trapping range of these devices is limited (usually the coverage radius of a single device does not exceed 5 meters), and the position and height cannot be adjusted according to the growth stage of the lotus roots. As a result, thrips in the central part of the field (especially the populations that gather on newly emerging upright leaves and young shoots) have difficulty sensing the trapping signals, making it a trapping blind spot.

[0007] Therefore, this invention proposes a thrips pest trapping device based on lotus root cultivation to solve the above-mentioned problems. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a thrips trapping device based on lotus root cultivation. This device floats at a fixed point on the surface of the lotus root field, precisely adapting to the aquatic environment of lotus root cultivation. It can be flexibly deployed in any area of ​​the field, effectively covering the entire water area for thrips control.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows: a thrips pest trapping device based on lotus root cultivation, comprising a base, an installation column fixedly connected to the top of the base, a fixing plate fixedly connected to the top of the installation column, and a placement opening extending to the bottom of the base at the center of the top of the fixing plate; a plurality of attraction lamps are installed in a circular array on the surface of the installation column, and an electric shock net covering the installation column is provided at the bottom of the fixing plate; a ring-shaped collection seat is threadedly connected to the outside of the base.

[0010] It also includes a stabilizing cover, a ring-shaped buffer groove at the top of the fixed plate, a buffer ring slidingly fitted inside the buffer groove, a number of first springs fixedly connected to the bottom of the buffer ring, and the lower ends of the first springs fixedly connected to the bottom wall of the buffer groove; a number of slots are arranged in a ring array at the top of the buffer ring, and a number of locking blocks corresponding to the slots are provided at the bottom of the stabilizing cover; a traction line is fixedly connected to the center of the bottom of the stabilizing cover, and a counterweight is fixedly connected to the bottom of the traction line, and the diameter of the counterweight is smaller than the diameter of the placement opening.

[0011] Basic Solution Principle: This solution is designed for the aquatic environment of lotus root fields and the habits of thrips. Its core principle is to achieve thrips control through a coordinated approach of "fixed-point floating - signal attraction - electric shock killing - stabilization and protection." The base provides buoyancy support, allowing it to float on the water surface. A counterweight sinks to the bottom through the placement port, and a traction line pulls the stabilizing cover, ensuring the device stands vertically in the water and can be deployed at a fixed point. A ring array of attraction lights on the mounting column releases color-attracting signals that thrips are sensitive to, attracting thrips from the field (including gaps between floating and upright leaves). An electric shock net at the bottom of the fixing plate covers the mounting column, electrocuting the attracted thrips. The dead insects naturally fall into a collection seat connected by threads on the outside of the base. A buffer ring and a first spring in the buffer groove buffer the impact of water flow or plant collisions. The stabilizing cover is quickly installed and removed via a locking mechanism with the buffer ring, facilitating maintenance of the attraction lights and electric shock net.

[0012] The above-mentioned solution offers the following advantages: Compared to existing technologies, this solution is adapted to the aquatic environment of lotus root fields and the needs of thrips control, effectively overcoming the limitation of traditional devices that can only be deployed at the edge of the field and cannot cover the central part of the field. The device floats on the water surface thanks to the buoyancy support provided by the base, while the counterweight sinks to the bottom through the placement port and is stabilized by a traction line, allowing for flexible and targeted placement in the densely planted central part of the field, breaking through blind spots caused by plant obstruction. The circular array of attraction lights on the mounting column releases thrips-sensitive color-attraction signals from multiple directions, covering the upper surface of floating leaves and penetrating gaps to illuminate the lower surface of upright leaves and other areas where thrips concentrate and hide. Combined with an electric shock net, this achieves highly efficient killing, and the dead insects naturally fall into the collection seat for centralized disposal. The buffer ring and the first spring can buffer the impact of water flow or the collision of blades, ensuring that the device stands stably in dynamic water bodies; the stabilizing cover can be quickly disassembled and assembled through the clips and slots, which facilitates the maintenance of the attraction lamp and the electric shock net, and the overall structure is friendly to ecological models such as lotus root and fish symbiosis, which improves practicality and enhances the thrips control effect.

[0013] Furthermore, the top of the base has a boss structure.

[0014] Beneficial effects: The protrusions can form a guide slope, guiding the insects knocked down by the electric shock net to slide quickly into the collection seat below, reducing the accumulation of insects on the top of the base, ensuring collection efficiency and the cleanliness of the device.

[0015] Furthermore, the fixed plate is equipped with a cleaning component for cleaning debris from the surface of the electric shock mesh based on the movement of the buffer ring.

[0016] Beneficial effects: The cleaning component is automatically triggered by the natural movement of the buffer ring (such as water flow impact or sliding caused by plant collisions), cleaning the surface of the electric shock mesh without additional power. It can promptly remove attached dead insect residue, fallen leaf debris, and other debris. This not only reduces the accumulation of debris clogging the electric shock mesh and weakening the shock intensity, ensuring continuous and efficient killing of thrips, but also reduces the frequency of manual disassembly and cleaning, lowering maintenance costs. It is especially suitable for the complex environment of lotus root fields where it is damp and debris easily adheres, further enhancing the long-term practicality of the device.

[0017] Furthermore, the cleaning component includes a rotating cavity inside the fixed plate, located below the buffer groove. A rotating ring is rotatably fitted inside the rotating cavity, and several teeth are arranged in a ring on the inner side of the rotating ring. Several driving cavities are arranged in a ring array on the inner side wall of the rotating cavity near the placement port. Sliding blocks are slidably fitted inside each driving cavity. A second spring located in the driving cavity is fixedly connected to one end of each sliding block, and the end of the second spring away from the sliding block is fixedly connected to the side wall of the driving cavity. Several ratchet teeth that engage with the teeth are hinged to the side of each sliding block near the rotating ring.

[0018] Each drive chamber has an air supply channel at the end away from the second spring, and the air supply channel is connected to the buffer groove; each drive chamber is equipped with a balancing component for balancing the air pressure inside the drive chamber at the end near the second spring.

[0019] The bottom of the fixed plate has an annular groove corresponding to the rotating ring. Several cleaning rods are fixedly connected to the bottom of the rotating ring. The bottom ends of the cleaning rods all pass through the annular groove and extend to the bottom of the electric shock net. A brush layer is provided on the side of the cleaning rods near the electric shock net, and the electric shock net is located within the movement trajectory of the brush layer.

[0020] Beneficial Effects: The cleaning component uses the natural movement of the buffer ring as its power source, achieving automatic cleaning of the electric shock net without additional energy consumption, making it suitable for the complex environment of lotus root fields. When the buffer ring slides, it compresses the gas in the buffer groove, which pushes the sliding block through the air supply channel. The ratchet teeth, in conjunction with the rotating ring teeth, drive the ring to rotate in one direction, causing the cleaning rod and brush layer to move along the circumference of the electric shock net, thoroughly cleaning dead insects, fallen leaves, and other debris. The balancing component ensures stable air pressure in the drive chamber, guaranteeing smooth movement. This reduces debris clogging the electric shock net, weakening its killing power, reducing the frequency of manual cleaning, lowering maintenance costs, and improving the device's continuous control effectiveness and long-term practicality.

[0021] Furthermore, all balancing components include a balancing channel that connects to the outside world.

[0022] Beneficial effects: The balancing channel can precisely balance the air pressure inside the drive chamber. When the sliding block is pushed or reset by gas, the change in the volume of the drive chamber causes air pressure fluctuations. The balancing channel can promptly introduce external air to replenish the pressure or prevent gas leakage, ensuring smooth reciprocating motion of the sliding block, providing stable power for the rotating ring drive and brush layer cleaning, and ensuring efficient operation of the cleaning components.

[0023] Furthermore, the top of the fixed plate has a ring-shaped water collection groove with a diameter smaller than that of the buffer groove; the bottom center of the stabilizing cover has an arc-shaped groove structure, and the edge of the arc-shaped groove corresponds to the water collection groove.

[0024] Several drainage channels are opened at the bottom of the water collection tank. All drainage channels are connected to the side wall of the base and extend into the collection base.

[0025] Beneficial effects: Precisely adapted to the high-temperature environment of summer when thrips are prevalent, the stable cap's arc-shaped groove at the bottom efficiently collects water vapor from the air, which condenses into water and flows into the water collection trough along the edge of the groove. The collected water is directed into the collection seat through the drainage channel, which moistens the dead insect residue in the collection seat, reducing its drying and clumping, making it difficult to clean; at the same time, it can rinse the inner wall of the collection seat, reducing insect residue, and maintaining the cleanliness of the collection seat without the need for manual addition of water.

[0026] Furthermore, the stabilizing cover is made of a transparent material.

[0027] Beneficial effects: The stabilizing cover is made of transparent material, which allows sunlight to penetrate and shine into the water collection tank and the placement opening. It absorbs light energy to increase the water temperature inside the tank and on the water surface, and accelerates water evaporation. This not only reduces water accumulation and bacterial growth, but also promotes the "evaporation-condensation" cycle, enhancing the continuous moisturizing and cleaning effect on the collection seat.

[0028] Furthermore, the inner wall of the arc-shaped groove of the stabilizing cap is coated with a hydrophobic layer.

[0029] Beneficial effects: The hydrophobic layer on the inner wall of the arc-shaped groove can reduce the adhesion of condensate, allowing water droplets to quickly gather into clusters and slide down the groove wall into the water collection tank, reducing water retention or residue.

[0030] Furthermore, the surface of the mounting column is provided with several auxiliary trapping components corresponding to the drainage channel; the auxiliary trapping components are used to configure the liquid flowing through the drainage channel into a disinfectant with insecticidal and bactericidal effects before it flows into the collection seat.

[0031] Beneficial effects: This solution converts the condensate from the drainage channel into an insecticidal and disinfectant solution that flows into the collection seat, achieving an upgraded effect of "wastewater utilization". The disinfectant can disinfect pathogens carried by dead insects in the collection seat, reducing their spread with the water flow and preventing lotus root diseases; it can also kill thrips larvae and adults around the collection seat, supplementing the control effectiveness of the main trapping device.

[0032] Furthermore, each auxiliary trapping component includes an auxiliary hole on the surface of the mounting post, and each auxiliary hole is connected to a drainage channel; a disinfection rod is inserted into each auxiliary hole; the disinfection rod is composed of a combination of a solid agent for killing thrips and a solid agent for sterilization.

[0033] Beneficial effects: This solution utilizes the natural condensation from the drainage channel to slowly dissolve the thrips-killing and bactericidal solid agents in the disinfection sticks, automatically preparing a disinfectant solution and achieving efficient linkage between "water source-pesticide-control". The thrips-killing agent can supplement and kill any adult thrips and larvae that escape around the collection seat, while the bactericidal agent can eliminate pathogens carried by the thrips, cutting off the "insect-disease" transmission chain.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following detailed description illustrates the specific implementation method:

[0045] Example 1:

[0046] like Figure 1 and Figure 2 As shown, a thrips trapping device based on lotus root cultivation includes a base 2, a mounting post 10, and a fixing plate 4. The installation sequence from top to bottom is the fixing plate 4, the mounting post 10, and the base 2, all of which are integrally molded. The base 2, the mounting post 10, and the fixing plate 4 are all made of plastic material (such as polyethylene or polypropylene). Several attraction lamps 12 (distributed in a ring array) are screwed to the surface of the mounting post 10, releasing color-attracting signals from multiple directions to attract thrips pests on the lotus leaf surface. An electric shock net 3 (encircling the mounting post 10 and the attraction lamps 12) is screwed to the bottom of the fixing plate 4, thereby forming an all-round encirclement and killing of the attracted thrips, improving the trapping efficiency.

[0047] The outer side of the base 2 is threadedly connected to a ring-shaped collection seat 1, which can accurately catch thrips bodies that fall after being killed by the electric shock net 3, reducing the direct fall of the thrips into the lotus root field water (thrips often carry various pathogens; if the thrips fall into the water, the pathogens will spread with the water flow, and then re-infect healthy lotus root leaves, inducing secondary diseases); at the same time, the threaded connection design between the base 2 and the collection seat 1 also facilitates quick disassembly of the collection seat 1 to clean the thrips, taking into account both disease control and device maintenance convenience. Secondly, as... Figure 3As shown, the top of the base 2 has a boss structure. On the one hand, it can increase the contact area with the mounting column 10, provide a more stable support base for the mounting column 10, improve the assembly strength of the two, reduce the shaking of the device when impacted by water flow or collided with plants, and enhance the overall stability. On the other hand, the inclined surface formed by the boss can play a guiding role, guiding the insects knocked down by the electric shock net 3 to slide quickly into the collection seat 1 below, reducing the possibility of insects accumulating on the top of the base 2, and further ensuring the timeliness and efficiency of insect collection.

[0048] Meanwhile, regarding the positioning and placement scheme of this device in lotus root paddy fields, specifically, as follows: Figure 1 , Figure 2 and Figure 4 As shown, it also includes a stabilizing cover 6, a ring-shaped buffer groove 401 with a fixed plate 4 at the top, a buffer ring 5 slidingly fitted inside the buffer groove 401, and several first springs 403 welded to the bottom of the buffer ring 5, with the bottom of each first spring 403 welded to the bottom wall of the buffer groove 401; several slots are arranged in a ring array at the top of the buffer ring 5, and several locking blocks corresponding to the slots are integrally formed at the bottom of the stabilizing cover 6; a traction line 8 (which can be made of nylon and equipped with a threaded connector to ensure the stability of the traction line 8 in water for a long time) is threaded to the center of the bottom of the stabilizing cover 6, and a counterweight 9 (preferably spherical) is sleeved at the bottom of the traction line 8; a placement opening extending to the bottom of the base 2 is opened at the center of the top of the fixed plate 4, and the diameter of the counterweight 9 is smaller than the diameter of the placement opening.

[0049] The above usage process is as follows: When placing the device in the middle of the lotus root field or at multiple points, first remove the stabilizing cover 6—by separating the locking block and the slot, remove the stabilizing cover 6. Then, adjust the length of the traction line 8 according to the water depth of the preset placement point (to ensure that the traction line 8 can be tightened after the counterweight 9 sinks to the bottom). Place the main body of the device (including the base 2, mounting column 10, fixing plate 4, etc.) into the target water area. The base 2 floats on the water surface due to buoyancy. Then, insert the counterweight 9 from the placement port at the top of the fixing plate 4, so that it passes through the inside of the device and sinks to the bottom of the water. The traction line 8 is then straightened. With the help of the gravity of the counterweight 9, the stabilizing cover 6 (after subsequent installation) is pulled, so that the device stands vertically in the water and does not drift with the water flow, and is accurately fixed in the middle of the field.

[0050] After positioning, align the locking block of the stabilizing cover 6 with the slot of the buffer ring 5 and press it in place. The buffer ring 5 and the first spring 403 can buffer minor collisions during release and subsequent impacts from water flow and plants, as well as buffer against wind blowing in the field. Following this method, based on the area of ​​the lotus root field and the distribution of thrips pests, evenly deploy multiple devices along the field (e.g., one device every 8-12 meters) to ensure that the trapping range of each device overlaps, comprehensively covering the central and surrounding areas of the field, achieving blind-spot-free control. The insects can be easily cleaned from the screw-connected collection seat 1, ensuring continuous operation of the device.

[0051] In lotus root fields, the electric shock net 3 is constantly exposed to debris such as dead insects, fallen leaves, and other impurities. This debris clogs the mesh, weakens the electric shock intensity, and reduces the effectiveness of the trapping process. Furthermore, manual cleaning is time-consuming and labor-intensive. Therefore, this solution includes a cleaning component within the fixed plate 4 for cleaning debris from the surface of the electric shock net 3 based on the movement of the buffer ring 5. Specifically, in conjunction with… Figure 2 , Figure 4 and Figure 5 As shown, the cleaning assembly includes a rotating cavity 15 inside the fixed plate 4, located below the buffer groove 401. A rotating ring 14 is rotatably fitted inside the rotating cavity 15, and several teeth are arranged in a ring on the inner side of the rotating ring 14. Several driving cavities 16 are arranged in a ring array on the inner side wall of the rotating cavity 15 near the placement port. A sliding block 17 is slidably fitted inside each driving cavity 16. A second spring 18 located in the driving cavity 16 is bonded to one end of each sliding block 17, and the end of the second spring 18 away from the sliding block 17 is bonded to the side wall of the driving cavity 16. Several ratchet teeth that engage with the teeth are hinged to the side of each sliding block 17 near the rotating ring 14.

[0052] Each drive chamber 16 has an air supply channel at the end away from the second spring 18, which connects to the buffer groove 401. Each drive chamber 16 has a balance channel connected to the outside at the end near the second spring 18. The bottom of the fixed plate 4 has an annular groove corresponding to the rotating ring 14. Several cleaning rods 7 are fixedly connected to the bottom of the rotating ring 14. The bottom ends of the cleaning rods 7 pass through the annular groove and extend to the bottom of the electric shock net 3. Each cleaning rod 7 has a brush layer on the side near the electric shock net 3. The electric shock net 3 is located within the movement trajectory of the brush layer.

[0053] During the hot and windy season when thrips are active, the surface of the lotus root field is easily affected by the wind, causing the floating base 2 to sway slightly with the water waves. When the base 2 sways, the stabilizing cover 6 will move up and down due to the pulling action of the traction line 8 and the counterweight 9. When the stabilizing cover 6 moves downward, it will directly squeeze the buffer ring 5, forcing the buffer ring 5 to slide down along the buffer groove 401 and compress the first spring 403. At this time, the internal volume of the buffer groove 401 is reduced, and the gas in the cavity is compressed. The compressed gas quickly enters the drive cavity 16 through the gas supply channel, pushing the sliding block 17 to slide away from the gas supply channel and compressing the second spring 18. During the movement of the sliding block 17, the ratchet hinged on its side wall meshes with the teeth on the inner side of the rotating ring 14, thereby driving the rotating ring 14 to rotate unidirectionally along the rotating cavity 15. When the stabilizing cover 6 returns to its original position with the water surface fluctuations, the elastic potential energy of the first spring 403 is released, pushing the buffer ring 5 to slide upwards and return to its original position along the buffer groove 401. The second spring 18 then pulls the sliding block 17 to return to its original position. The ratchet deflects and slips under the action of the inclined surface of the teeth, preventing the rotating ring 14 from rotating in the opposite direction. At the same time, the balance channel ensures the air pressure balance at the end of the drive chamber 16 near the second spring 18, ensuring the continuous stability of the action. This cycle continues, with the water surface fluctuations causing the buffer ring 5 to slide back and forth, continuously forming a compression-reset cycle on the gas in the buffer groove 401. The gas drives the sliding block 17 to reciprocate, and with the help of the unidirectional transmission characteristics of the ratchet and teeth, the rotating ring 14 continues to rotate in one direction. Finally, the brush layer on the cleaning rod 7 makes a circular motion along the surface of the electric shock mesh 3, thus cleaning up the debris.

[0054] Example 2:

[0055] The difference from the above embodiments is that, as Figure 2 As shown, the top of the fixed disk 4 has a ring-shaped water collection trough 402, the diameter of which is smaller than the diameter of the buffer trough 401; combined with Figure 3As shown, the bottom center of the stabilizing cover 6 has an arc-shaped groove structure, and the edge of the arc-shaped groove corresponds to the water collection tank 402. At the same time, the bottom of the water collection tank 402 has several drainage channels 13, all of which are connected to the side wall of the base 2 and extend into the collection seat 1. The stabilizing cover 6 is made of transparent material, and the inner wall of the arc-shaped groove of the stabilizing cover 6 is coated with a hydrophobic layer. Firstly, the high temperatures and humidity of summer, when thrips are prevalent, combined with the strong transpiration from the lotus root field surface and high water vapor content in the air, allow the curved groove at the bottom of the stabilizing cover 6 to efficiently collect water droplets condensing upon contact with the cover, utilizing the water-gathering properties of the curved surface. The hydrophobic coating on the inner wall significantly reduces water droplet adhesion and water retention, allowing the droplets to quickly slide down the groove wall to the water collection trough 402, ensuring efficient water collection. Then, the condensate is directed through the drainage channel 13, guiding it into the collection seat 1. This moistens the dead insect residue inside the seat, preventing it from drying and clumping, while also rinsing the inner wall to reduce residue. This eliminates the need for manual water addition to maintain the cleanliness of the collection seat 1. Furthermore, the moist insect residue inside the collection seat 1 is less likely to dry and generate dust, reducing the spread of potential pathogens carried by dead insects. At the same time, the continuous small flow of water dilutes the stench of dead insects, reducing the aggregation of scavenging secondary pests such as flies and lowering the risk of them harming the tender lotus leaves.

[0056] Meanwhile, although the condensate reduces the spread of pathogens caused by the dust from dead insects, it cannot completely eliminate the pathogens carried by the insects. Therefore, this solution provides several auxiliary trapping components on the surface of the mounting column 10 that correspond to the drainage channel 13. The auxiliary trapping components are used to configure the liquid flowing through the drainage channel 13 into a disinfectant with insecticidal and bactericidal effects before it flows into the collection seat 1.

[0057] Specifically, such as Figure 2 and Figure 3As shown, each auxiliary trapping component includes an auxiliary hole 11 on the surface of the mounting post 10, and each auxiliary hole 11 is connected to a drainage channel 13. A disinfection rod is inserted into each auxiliary hole 11. The disinfection rod is composed of a solid agent for killing thrips and a solid agent for sterilization (e.g., thiamethoxam + carbendazim, imidacloprid + chlorothalonil). Specifically, the selected disinfection rod is slowly inserted axially along the auxiliary hole 11 until the rod is completely embedded in the hole, leaving only 0.5-1 cm of the end exposed (for easy replacement later). Because the auxiliary hole 11 is directly connected to the drainage channel 13, the surface of the disinfection rod can directly contact the condensate flowing through the drainage channel 13 after insertion, without the need for an additional sealing structure. In hot and humid summer conditions, the condensate collected by the arc-shaped groove of the stabilizing cover 6 flows into the water collection tank 402 and is then transported to the collection seat 1 through the drainage channel 13. The water flow continuously washes the surface of the disinfection rod inside the auxiliary hole 11. Solid pesticides dissolve slowly with the water flow, forming a mixed disinfectant solution containing thrips-killing and bactericidal components. The concentration is dynamically balanced with the flow rate of condensate water (when the water flow is slow, the pesticide release is gentle, reducing the sudden increase in concentration). After the disinfectant solution flows into the collection seat 1 along the drainage channel 13, on the one hand, the thrips-killing components (such as thiamethoxam) have a contact and stomach poison effect on the adult / nymph thrips that were missed by the electric shock net 3 and fell to the vicinity of the collection seat 1, achieving "attracting and killing + supplementary killing"; on the other hand, the bactericidal components (such as carbendazim) directly act on the dead insect residue and inner wall of the collection seat 1, disinfecting the pathogens carried by the thrips and cutting off the disease transmission chain.

[0058] The following is a comparison of experiments conducted using this method with traditional methods:

[0059] Control group: The traditional blue sticky insect trap method was used, with one sticky insect trap placed every 10m, and the hanging height was level with the top of the lotus root leaves, for a total of 10 traps / field; Experimental group: The device of this scheme was used, with one device placed every 10m, for a total of 10 devices / field.

[0060] The relevant data table is as follows:

[0062] Group Week 1 Week 2 Week 3 Week 4 Overall Average control group 82±7 65±5 48±4 32±3 56.75 experimental group 156±11 142±9 135±8 128±7 140.25

[0063] Table 1 clearly shows that the trapping efficiency of this scheme is superior to that of traditional methods. The total average trapping rate of the control group was only 56.75 thrips / unit / week, while the total average trapping rate of experimental group 2 was as high as 140.25 thrips / unit / week, an increase of 147.1% compared with the control group. In terms of periodic changes, the control group showed the largest decrease in the trapping rate over time, from 82 thrips in week 1 to 32 thrips in week 4, a decrease of 61.0%, which is presumably related to the decrease in stickiness of the sticky traps and the accumulation of thrips obstructing the view. The experimental group showed a decrease of only 18.0%, proving that the structural optimization of the device can effectively improve the efficiency and sustainability of thrips control in lotus root fields.
