Description

Technical Field

[0001] This application relates to the technical field of pest control equipment in tobacco cultivation, and in particular to a highly efficient trapping device for thrips and aphids in flue-cured tobacco. Background Technology

[0002] During the cultivation of flue-cured tobacco, aphids and thrips are two common and serious pests: aphids cause the leaves to lose their green color and curl by sucking the sap of flue-cured tobacco leaves, and they can also spread viral diseases; thrips feed on the tender shoots, leaves and flower buds of flue-cured tobacco with their rasping and sucking mouthparts, causing silvery-white spots on the leaves and deformed tender shoots, while also spreading tomato wilt disease, which directly affects the yield and quality of flue-cured tobacco. Currently, the trapping devices for tobacco aphids and thrips have the following main shortcomings: 1. Low trapping efficiency: Existing equipment mostly uses sticky traps of a single color (such as only yellow sticky traps), which can only target and trap one of aphids or thrips, and cannot trap two types of pests at the same time efficiently; moreover, sticky traps are mostly flat single sheets, with limited trapping area and low probability of pest contact.

[0003] 2. Cumbersome replacement operation: Some devices have the sticky insect board and pheromone container fixedly connected as an inseparable structure. When the sticky insect board is full of insects, it needs to be replaced as a whole. This not only increases the cost of consumables, but also requires the disassembly of multiple fixed parts, which is time-consuming.

[0004] 3. Uneconomical use of pheromones: Most existing pheromone containers are designed for single use only. Once the pheromones are released, they must be discarded as a whole, and pheromones cannot be replenished repeatedly, resulting in material waste and increased usage costs.

[0005] 4. Poor structural stability and durability: Some insect traps are suspended by simple hooks, which are easily affected by wind and shake, causing pests to escape; in addition, the rain protection is insufficient, and rainwater directly washes away the sticky insect traps, which will destroy the sticky adhesive and shorten the service life of the traps.

[0006] 5. Unreliable installation and fixation: The existing equipment's ground-insertion structure is mostly a simple rod shape, which is easily tilted over due to soil loosening or wind force after being inserted into the field soil, and cannot be fixed stably for a long time.

[0007] To address the aforementioned issues, there is an urgent need to design a trapping device that can simultaneously and efficiently trap aphids and thrips, is easy to replace, has reusable pheromones, and is structurally stable and durable, in order to meet the pest control needs during the tobacco planting process. Summary of the Invention

[0008] This application aims to at least partially address one of the technical problems in the related art.

[0009] To achieve the above objectives, the first aspect of this application proposes a highly efficient trapping device for tobacco aphids and thrips, comprising: a support rod; a fixing box disposed on the support rod; a support column disposed within the fixing box; a plug-in rod disposed at the top of the support column; a multi-layer composite trapping assembly detachably mounted on the plug-in rod and positioned in conjunction with the top of the fixing box; an umbrella-shaped rainproof cover disposed at the top of the support rod and above the multi-layer composite trapping assembly; and a ground-inserting cone disposed at the bottom of the support rod. The multi-layer composite trapping assembly comprises: a pheromone attracting unit detachably connected to the top of the plug-in rod and having an internally perforated pheromone slow-release box; and a sticky insect board assembly located below the pheromone attracting unit, comprising four cross-shaped sticky insect board units, wherein the two sides of each sticky insect board unit are a yellow sticky insect surface and a blue sticky insect surface, a fixing tube that cooperates with the plug-in rod is disposed at the center of the cross, a groove is opened at the bottom edge, and a protrusion that cooperates with the groove is disposed at the top of the fixing box.

[0010] This application discloses a highly efficient trapping device for flue-cured tobacco aphids and thrips. It employs a yellow-blue double-sided sticky insect board with dual pheromones, combined with a cross-shaped sticky insect board structure, enabling simultaneous and efficient trapping of two types of pests, significantly improving the trapping area and efficiency. The sticky insect board can be replaced individually, and the pheromone slow-release box can be repeatedly replenished, making operation convenient and reducing costs. The fixing box protrusion matches the sticky insect board groove, and the metal ground-inserting cone design ensures structural stability. The umbrella-shaped rainproof top cover protects the sticky insect adhesive, and the support rod is adjustable to adapt to the entire growth stage of flue-cured tobacco, making it highly practical.

[0011] In addition, the highly efficient trapping device for tobacco aphids and thrips proposed in this application may also have the following additional technical features: In one embodiment of this application, the fixing box is a box structure with an open top, and its outer wall is detachably fixed to the outer wall of the support rod by bolts; the protrusion is a rectangular block structure, and the height of the protrusion is adapted to the depth of the groove.

[0012] In one embodiment of this application, the bottom end of the support column is welded and fixed to the inner bottom wall of the fixing box, and the top end of the support column is threaded and fixed to the bottom end of the plug rod; the outer wall of the top end of the plug rod is provided with external threads, and the axial length of the plug rod is greater than the axial length of the fixing tube.

[0013] In one embodiment of this application, the four sticky insect board units have the same length and width, and the included angle between two adjacent sticky insect board units is 90°; the inner wall of the fixing tube is smooth, and the inner diameter of the fixing tube is adapted to the outer diameter of the plug rod, and the axial length of the fixing tube is 2-5cm.

[0014] In one embodiment of this application, the pheromone attracting unit is a cylindrical structure with an open bottom. The bottom of its inner wall is provided with an internal thread that matches the external thread at the top of the plug-in rod. The pheromone attracting unit is threadedly connected to the top of the plug-in rod. The pheromone slow-release box is fixed inside the pheromone attracting unit by a snap fastener. The pheromone slow-release box is filled with aphid alarm pheromone (E-β-farnesene) and thrips sex pheromone (myrcene).

[0015] In one embodiment of this application, the umbrella-shaped rainproof cover is made of rigid plastic, and the diameter of the umbrella-shaped rainproof cover is larger than the maximum lateral dimension of the multi-layer composite trapping assembly, so as to prevent rainwater from directly washing away the sticky insect board assembly.

[0016] In one embodiment of this application, the support rod is a height-adjustable structure, specifically a composite rod formed by threaded splicing of multiple rod segments.

[0017] In one embodiment of this application, the ground-inserting cone is a conical metal structure, with the top end of the ground-inserting cone threadedly fixed to the bottom end of the support rod, and the axial length of the ground-inserting cone is 15-30cm.

[0018] In one embodiment of this application, the sticky insect board assembly is a disposable component in the multi-layer composite trapping assembly. When the yellow and blue sticky insect surfaces of the sticky insect board are covered with insects, the pheromone attracting unit can be unscrewed, the old sticky insect board assembly can be removed, and a new sticky insect board assembly can be replaced. The pheromone slow-release box is a reusable component. When the internal pheromone release is complete, the pheromone attracting unit can be opened, and aphid and thrips pheromones can be added to the pheromone slow-release box for continued use.

[0019] The advantages of this application compared to existing technologies are: (1) Through the synergistic effect of “double-sided sticky insect board (yellow + blue) + dual pheromones (aphid alarm pheromone + thrips sex pheromone)”, aphids and thrips can be trapped efficiently at the same time; the cross-shaped sticky insect board structure increases the trapping area, and the hollow design of the pheromone slow-release box accelerates the diffusion of pheromones, further improving the trapping effect.

[0020] (2) Both the sticky insect board assembly and the pheromone attracting unit are designed to be detachable. After the sticky insect board is full of insects, only the sticky insect board assembly needs to be replaced. There is no need to disassemble the whole device, and the operation time is short. The pheromone can be replenished repeatedly to avoid waste of resources.

[0021] (3) The fixed box protrusion is inserted into the slot of the sticky insect board to prevent the sticky insect board from shaking; the metal ground cone is inserted into the soil to ensure that the whole device is not easy to tip over and adapt to the wind environment in the field.

[0022] (4) The umbrella-shaped rainproof cover effectively blocks rainwater and protects the sticky insect board; the support rod, ground cone and other parts are made of durable materials to extend the overall service life of the device.

[0023] (5) The height of the support rod is adjustable, and the trapping height can be adjusted according to different growth stages of flue-cured tobacco to meet the pest control needs throughout the entire growth period.

[0024] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0027] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The following describes an embodiment of the present application of a highly efficient trapping device for tobacco aphids and thrips, with reference to the accompanying drawings.

[0029] like Figures 1-4 As shown in the figure, an efficient trapping device for tobacco aphids and thrips according to an embodiment of this application achieves efficient trapping of aphids and thrips and convenient maintenance. The specific implementation method is described in detail below from three dimensions: component structure, operation, maintenance and replacement.

[0030] Example 1: Detailed structural design of each component of the device 1. Structural design of support rod 1 Support rod 1 is the main support component of the device. It is a composite rod made of multiple rod sections spliced ​​together by threads, which is used to adapt to the height requirements of flue-cured tobacco at different growth stages. Each rod section is made of stainless steel. One end of a single rod section is machined with external threads, and the other end is machined with internal threads. The inner wall of the internally threaded section is provided with anti-slip texture (to enhance the stability after splicing and prevent the rod section from loosening due to wind in the field).

[0031] 2. Structural design of fixing box 2 The fixing box 2 is a box structure with an open top, made of ABS plastic (which is lightweight, aging-resistant, and impact-resistant, suitable for open field environments), and the box is cubic in shape. Two ear plates with bolt holes are symmetrically arranged on the outer wall of the fixing box 2. The fixing box 2 is detachably fixed to the support rod 1 by passing stainless steel bolts through the ear plates. A support column 3 is welded to the center of the inner bottom wall of the fixing box 2, and the welding is done using a full welding process. At each of the four corners of the top of the fixing box 2, a rectangular block-shaped protrusion 21 is integrally formed. The height of the protrusion 21 matches the depth of the groove 523 of the sticky insect board assembly 52 (the height of the protrusion 21 is slightly less than the depth of the groove 523 by 1-2 mm, ensuring a tight connection while preventing jamming during installation). The width of the protrusion 21 is the same as the width of the groove 523, and the top of the protrusion 21 is chamfered (to guide the groove 523 to quickly align and insert, improving installation efficiency). 3. Structural design of support column 3 and connector rod 4 The support column 3 is made of stainless steel round rod, and its bottom end is fully welded to the center of the inner bottom wall of the fixing box 2. The top end is machined with external threads (thread length 5-8mm, to meet the connection strength with the plug rod 4). The plug-in rod 4 is also made of stainless steel, with a diameter slightly smaller than that of the support column 3. Its bottom end has an internally threaded hole (fitting the external thread at the top of the support column 3, with a thread engagement length of not less than 5mm to ensure a stable connection), and its top end has an external thread (6mm in length, sufficient to fully engage with the internal thread of the pheromone attracting unit 51 to prevent loosening). The overall axial length of the plug-in rod 4 is greater than the length of the fixing tube 522 of the sticky insect board assembly 52 (ensuring that after the fixing tube 522 is inserted, the top of the plug-in rod 4 still has a sufficient threaded section to connect with the pheromone attracting unit 51). 4. Structural Design of Multi-Layer Composite Trapping Component 5 The multi-layer composite trapping component 5 is the core trapping component of the device. It is detachably assembled on the plug rod 4 and consists of a pheromone trapping unit 51 and an insect sticky board component 52. (1) Structural design of pheromone trapping unit 51 The pheromone attracting unit 51 is a cylindrical structure with an open bottom. It is made of ABS plastic (lightweight and easy to process). The inner wall of the cylindrical structure is machined with internal threads near the bottom (to match the external threads at the top of the plug rod 4, and the thread precision ensures a tight fit without shaking). The top of the cylindrical structure is equipped with a detachable end cap (connected by a snap-fit, making it easy to open and put in the pheromone release box 511). The pheromone collection unit 51 has a pheromone release box 511 inside. The pheromone release box 511 is a rectangular box with hollowed-out sides (made of ABS plastic, 1-2mm thick to ensure durability). Two elastic buckles are symmetrically arranged on its outer wall (the buckles are made of plastic material with a certain deformation capacity and have a barb structure at the end). The inner wall of the pheromone collection unit 51 has a corresponding slot (the depth of the slot is adapted to the length of the buckle barb). Through the engagement of the elastic buckles and the slots, the pheromone release box 511 can be detachably fixed in the collection unit (for easy removal and replenishment of pheromones). The pheromone slow-release box 511 has evenly spaced strip-shaped perforations (hole width 3-5mm, hole length 10-15mm, hole spacing 2-3mm) to ensure that the internal pheromones can be evenly diffused into the field environment. Inside the pheromone slow-release box 511, there is an adsorption carrier (such as porous sponge or degreased cotton, which has strong adsorption capacity and stable pheromone release). The adsorption carrier adsorbs aphid alarm pheromone (E-β-farnesene) and thrips sex pheromone (myrcene).

[0032] It should be noted that the pheromone release box 511 can be loaded with aphid alarm pheromone (E-β-farnesene) and thrips sex pheromone (myrcene) respectively using physically separated independent adsorption carriers.

[0033] This design ensures that the two pheromones with different mechanisms of action (repulsion and attraction) are released synergistically in space rather than directly mixed, thus avoiding mutual interference. Their synergistic working mechanism is as follows: Repellency activation: Aphid alarm pheromones first spread, repelling surrounding aphids and causing them to detach from the host plant and disperse in the air.

[0034] Localization by attraction: Thrips release sex pheromones simultaneously, forming an attraction center that directs thrips toward the device.

[0035] Visual termination: The pests that were driven or lured to the vicinity of the device were eventually captured by the strong visual stimulation provided by the cross-shaped yellow and blue sticky insect board 52.

[0036] This multi-mode trapping system, which combines repulsion and attraction with pheromone and color coordination, effectively expands the trapping range of single-point devices and significantly improves the efficiency of simultaneous control of aphids and thrips. It is one of the core innovations of this device in achieving efficient trapping.

[0037] (2) Structural design of sticky insect board assembly 52 The sticky insect board assembly 52 is located below the pheromone attracting unit 51 and consists of four sticky insect board units 521 and a fixing tube 522. Each sticky insect board unit 521 has two surfaces coated with sticky insect adhesive: one side is yellow sticky insect adhesive (targeting aphids' attraction to yellow, using a high-viscosity, sun-resistant special sticky insect adhesive), and the other side is blue sticky insect adhesive (targeting thrips' attraction to blue, the adhesive formula is the same as the yellow adhesive, only the color is different). The sticky insect adhesive is applied to 90% of the surface of the sticky insect board unit 521 (leaving a 1cm wide unadhesive area at the edge for easy handling during installation and to avoid stickiness), and the coating thickness is uniform (0.08-0.12mm, ensuring the sticky insect effect and preventing dripping due to excessive adhesive layer). Four sticky insect trap units 521 are fixed in a cross shape, with the intersection point being the center area of ​​each sticky insect trap unit 521. The included angle between any two adjacent sticky insect trap units 521 is strictly controlled at 90° (to ensure that the trapping area evenly covers the entire perimeter without any blind spots). At the center of the intersection of the four sticky insect trap units 521, a fixing tube 522 is vertically welded. The inner diameter of the fixing tube 522 is adapted to the outer diameter of the plug-in rod 4 (the gap does not exceed 0.2mm, which ensures smooth installation and prevents shaking after insertion). Each sticky insect board unit 521 has a rectangular slot 523 centered on its bottom edge. The width of the slot 523 is the same as the width of the protrusion 21 of the fixing box 2, and the depth of the slot 523 is slightly greater than the height of the protrusion 21 (the difference is 1-2mm to ensure that the protrusion 21 can be fully inserted into the slot 523). 5. Structural design of the umbrella-shaped rainproof canopy 6 The umbrella-shaped rainproof cover 6 is made of hard plastic (preferably PP plastic, which is impact-resistant, UV-resistant, and suitable for outdoor exposure to sun and rain). It is umbrella-shaped and the diameter of the cover is larger than the maximum lateral dimension of the multi-layer composite trapping component 5 (to ensure that rainwater can completely cover the trapping component and prevent rainwater from directly washing away the sticky insect glue on the sticky insect board component 52). At the bottom center of the umbrella-shaped rainproof cover 6, there is an integrally formed connecting sleeve that allows the umbrella-shaped rainproof cover 6 to be detachably fixed to the top of the support rod 1 (for easy installation and replacement). The edges of the umbrella-shaped rainproof cover 6 are slightly curved downwards (curve angle 5-10°, to guide rainwater to drip quickly along the edges and prevent rainwater from accumulating on the surface of the cover and seeping into the trapping component). 6. Structural design of the ground-inserting cone 7 The ground-inserting cone 7 is a cone-shaped metal structure with a sharp cone tip (30-45° angle for easy and quick insertion into the field soil). The outer side of the cone body is machined with spiral patterns (to enhance friction with the soil and prevent the device from tipping over due to wind or loose soil). Example 2: Field Operation Procedures for the Device 1. Field site selection and fixation Choose locations in flue-cured tobacco fields where pests are frequently active and well-ventilated (such as the passageways between rows in the flue-cured tobacco fields, or areas where pests have previously been severe). Avoid choosing low-lying, waterlogged areas (to prevent the fixing box 2 from being soaked and damaged) or under the shade of trees (to affect the diffusion of pheromones and the trapping effect of sticky insects). Hold the upper middle part of the support rod 1 with both hands, align the tip of the ground-inserting cone 7 with the soil at the target location, press down vertically and rotate slightly (rotation can reduce insertion resistance, especially for clay soil), until the ground-inserting cone 7 is inserted into the soil to a depth of more than 2 / 3 of its total length (e.g., a 20cm long ground-inserting cone 7 needs to be inserted more than 15cm). After releasing the support rod 1, if the device stands upright without shaking, it means that it is fixed firmly. 2. Daily monitoring and status checks Regularly check the condition of the equipment in the field every week (avoid checking on rainy days to prevent the sticky adhesive from being diluted by rainwater). The check includes: The sticky insect board assembly 52 is used to check the number of aphids on the yellow sticky insect surface and the number of thrips on the blue sticky insect surface to determine whether the sticky insect adhesive is still sticky (if the insect body coverage area of ​​the sticky insect surface exceeds 80%, or the sticky insect adhesive surface is covered with dust, causing the stickiness to decrease, the sticky insect board assembly 52 needs to be replaced). Pheromones release status: A slight pheromone scent can be detected when the device is brought close (if the scent is faint or absent, pheromones need to be replenished). Overall stability of the device: Check whether the support rod 1 is tilted, whether the ground cone 7 is loose, and whether the bolts of the fixing box 2 are loose. If any abnormality is found, adjust and fix it in time.

[0038] Example 3: Maintenance and Replacement Procedures for the Device 1. Replacement of sticky insect board assembly 52 When the sticky insect board assembly 52 needs to be replaced, the operating procedure is as follows: Hold the cylindrical outer wall of the pheromone attracting unit 51 with both hands (avoid contact with the slow-release box area), rotate the attracting unit counterclockwise until it is completely separated from the plug rod 4, and gently place the attracting unit on a clean tray or plastic bag (avoid contamination by sticky insect glue). Hold the two opposite non-adhesive areas of the old sticky insect board component 52 with both hands and gently lift it upwards (if the groove 523 and the protrusion 21 fit tightly, you can gently shake it left and right before lifting) until the fixing tube 522 is completely detached from the plug rod 4. Take out the old component and put it into a special recycling bag (to prevent the insects from scattering and to dispose of them uniformly later). Take the new sticky insect board assembly 52 and reassemble it onto the plug rod 4, ensuring that the slot 523 and the protrusion 21 fit securely together. Rotate the pheromone attracting unit 51 back to the top of the plug rod 4 to ensure a secure connection. 2. Pheromones supplementation When the pheromone in the pheromone release cartridge 511 has been completely released, the operating steps are as follows: Rotate the pheromone attracting unit 51 counterclockwise to separate it from the plug rod 4 and place it on a clean surface; Open the top end cap of the attraction unit, press the elastic buckles on both sides of the pheromone release box 511, and take out the release box; Discard the old adsorbent in the slow-release box, put in a new adsorbent, and add aphid alarm pheromones and thrips sex pheromones. Reinsert the replenished pheromone slow-release box into the slot of the attracting unit, close the end cap, and then screw the attracting unit back to the top of the plug rod 4. 3. Maintenance of other components If the connection of the support rod 1 is loose, rotate the loose rod clockwise until it is secure. If necessary, add anti-rust grease to the threads. If the umbrella-shaped rain cover 6 is cracked or damaged, remove it directly and replace it with a new cover to ensure rain protection. If the tip of the ground stake 7 is severely worn, the old ground stake 7 can be removed by rotating it counterclockwise and replaced with a new ground stake 7 to ensure that it is firmly fixed in the field.

[0039] In summary, the efficient trapping device for flue-cured tobacco aphids and thrips according to the embodiments of this application uses a yellow and blue double-sided sticky insect board with dual pheromones and a cross-shaped sticky insect board structure, which can simultaneously and efficiently trap two types of pests, significantly improving the trapping area and efficiency; the sticky insect board can be replaced individually, and the pheromone slow-release box 511 can be repeatedly replenished, making operation convenient and reducing costs; the protrusion 21 of the fixing box 2 cooperates with the groove 523 of the sticky insect board, and the design of the metal ground cone 7 ensures structural stability; the umbrella-shaped rainproof top cover 6 protects the sticky insect adhesive; and the support rod 1 is adjustable to adapt to the entire growth period of flue-cured tobacco, making it highly practical.
