Description

Technical Field

[0001] This utility model belongs to the field of insect capture technology, specifically relating to a detachable poplar longhorn beetle capture box. Background Technology

[0002] Longhorn beetles are a significant pest in forestry. Their larvae are mostly found on tree trunks, boring into them for food. If not treated and captured promptly, they can cause rapid tree death. Current methods for capturing longhorn beetles primarily use bump traps. These devices are placed on the tips of branches. When longhorn beetles change host trees in the forest, they are attracted by the scent emitted by a built-in attractant, causing them to bump into the bump trap and become trapped. This device has been very helpful in capturing longhorn beetles since its invention, but the capture rate remains limited. This is because longhorn beetles mainly feed on the tree trunk, which is where they congregate most. Therefore, capturing longhorn beetles directly on the trunk would greatly improve capture efficiency. Existing patent CN202222103987.2, patent name... The patent document for a tree trunk-type longhorn beetle trap describes a longhorn beetle trapping device that uses cage-like traps placed on tree trunks with escape-proof treatment at the entrance. When a longhorn beetle crawls into the trap, it is captured. This method has a simple structure and can capture both larvae and adults of longhorn beetles in the tree trunk area. However, processing the captured longhorn beetles is quite complicated, requiring the entire device to be dismantled before processing and transporting them. Furthermore, the main body of the cage-like trap is a woven mesh structure, making it difficult to remove longhorn beetles whose feet or antennae have entered the mesh, increasing the difficulty of cleaning them. Therefore, developing a tree trunk-type trapping device that can quickly process and transport captured longhorn beetles is very much in line with practical needs. Utility Model Content

[0003] In order to solve the problem that existing tree trunk-type longhorn beetle trapping devices have great difficulty in processing and transporting the captured longhorn beetles, this utility model provides a detachable poplar longhorn beetle trapping box.

[0004] A detachable poplar longhorn beetle trapping box, which can be detachably installed on the trunk of a poplar tree, includes two trapping units that are assembled to form a ring-shaped box.

[0005] The capturing unit includes a base, the top of which is detachably connected to a capturing chamber for containing longhorn beetles, and the top of the capturing chamber is detachably connected to a top cover to prevent the longhorn beetles from escaping.

[0006] The fixed base is equipped with a chamber for holding the longhorn beetle trapping agent, and the chamber is connected to the capture chamber. The longhorn beetle trapping agent is released to the outside of the capture box through the capture chamber and the top cover in sequence, and induces the longhorn beetles on the poplar trunk to climb through the top cover into the capture chamber.

[0007] Furthermore, the fixing base includes an annular support plate, on which a clamp half-ring for fixing to the poplar trunk is installed. An annular groove for containing longhorn beetle trapping agent is fixed at the bottom of the annular support plate. Several honeycomb holes are machined on the annular support plate. The annular groove is connected to the top of the annular support plate through several honeycomb holes. An opening for placing the longhorn beetle trapping agent is machined on the side wall of the annular groove. A side wall baffle for preventing the trapping agent from falling is detachably installed at the opening.

[0008] Furthermore, a flexible rubber pad for contacting the tree trunk is fixed to the inner side of the clamp semi-ring;

[0009] Furthermore, a sealing ring is provided between the side wall baffle and the annular groove opening to prevent odor from escaping;

[0010] Furthermore, the capture chamber is a semi-annular chamber body. The capture chamber is detachably connected to the clamp semi-annular body. The bottom of the capture chamber is connected to the annular groove through several honeycomb holes, and the top of the capture chamber is connected to the top cover.

[0011] Furthermore, the top cover includes a mounting groove for detachable connection with the capture chamber, and a cover body for preventing the longhorn beetle from escaping is fixed to the top of the mounting groove, and at least one entry groove is machined on the cover body.

[0012] Furthermore, the groove is processed at the top of the cover, and the inner side of the cover is provided with a reverse ramp to prevent the longhorn beetle from crawling outward;

[0013] Furthermore, the entry groove is machined on the outer wall of the cover. The outer wall of the cover is formed by splicing multiple rectangular walls along an arc trajectory. Each rectangular wall has a corresponding entry groove machined on it. A baffle to prevent the longhorn beetle from crawling outward is installed on the inner side of each rectangular wall, and the baffle is set in correspondence with the entry groove.

[0014] Furthermore, the top of the cover is open, and a nylon mesh is fixed to the top opening of the cover;

[0015] The beneficial effects of this application compared to the prior art are:

[0016] 1. The detachable poplar longhorn beetle trapping box provided by this utility model adopts a modular design, which allows the storage structure of the longhorn beetle to be freely disassembled from the tree fixing structure. When it is necessary to process or transfer the captured longhorn beetles, it is only necessary to directly remove the trapping chamber from the clamp half ring, transfer the trapping chamber and the longhorn beetle together, and then install a new trapping chamber on the clamp half ring for direct use. This design greatly improves the efficiency of longhorn beetle transfer after capture and the convenience of on-site transfer.

[0017] 2. This utility model provides a detachable poplar longhorn beetle trapping box. A cover structure is provided on the top of the trapping chamber to prevent the longhorn beetles from escaping. This effectively traps the captured longhorn beetles inside the chamber, allowing them to be handled by staff. To further improve the trapping efficiency and success rate, an induction chamber is also provided on the main body of the trapping box. This chamber contains a longhorn beetle attractant, which increases the probability of the longhorn beetles crawling into the trapping box, thereby increasing the capture rate.

[0032] Specific implementation method one: Combining Figures 1 to 13 This embodiment describes a detachable poplar longhorn beetle trapping box. The trapping box can be detachably installed on the trunk of a poplar tree. The trapping box includes two trapping units, which are assembled to form a ring-shaped box.

[0033] The capturing unit includes a fixed base 1, and a capturing chamber 2 for accommodating longhorn beetles is detachably connected to the top of the fixed base 1. A top cover 3 for preventing longhorn beetles from escaping is detachably connected to the top of the capturing chamber 2.

[0034] The fixed base 1 is provided with a chamber for containing the longhorn beetle trapping agent, and the chamber is connected to the capture chamber 2. The longhorn beetle trapping agent is released to the outside of the capture box through the capture chamber 2 and the top cover 3 in sequence, and induces the longhorn beetles on the poplar trunk to climb into the capture chamber 2 through the top cover 3.

[0035] The fixing base 1 includes an annular support plate 12, on which a clamp half-ring 11 for fixing to the trunk of a poplar tree is installed. An annular groove 13 for containing longhorn beetle trapping agent is fixed at the bottom of the annular support plate 12. Several honeycomb holes are processed on the annular support plate 12. The annular groove 13 is connected to the top of the annular support plate 12 through several honeycomb holes. An opening for placing longhorn beetle trapping agent is processed on the side wall of the annular groove 13. A side wall baffle 14 for preventing the trapping agent from falling is detachably installed at the opening.

[0036] A flexible rubber pad 15 for contacting the tree trunk is fixed to the inner side of the clamp half-ring 11;

[0037] A sealing ring is provided between the side wall baffle 14 and the opening of the annular groove 13 to prevent odor from escaping;

[0038] The capture chamber 2 is a semi-annular chamber. The capture chamber 2 is detachably connected to the clamp semi-annular 11. The bottom of the capture chamber 2 is connected to the annular groove 13 through several honeycomb holes. The top of the capture chamber 2 is connected to the top cover 3.

[0039] The top cover 3 includes a mounting groove 31 for detachable connection with the capture chamber 2. The top of the mounting groove 31 is fixedly connected to a cover body 32 for preventing the longhorn beetle from escaping. At least one entry groove 33 is machined on the cover body 32.

[0040] This embodiment provides a detachable poplar longhorn beetle trapping box, which innovatively adopts a modular design. The fixing seat 1 in the trapping box is used to install the trapping box on the trunk of a poplar tree. The fixing seat 1 is connected by a clamp structure, and two clamp half-rings 11 are connected together by four bolts. Considering that the outer contour of the trunk clamping area is not a regular circle, a layer of flexible rubber pad 15 is attached to the inner wall of the clamp half-ring 11. The flexible rubber pad 15 has multiple functions. The first function is to protect the tree and avoid damage to the tree surface caused by rigid contact between the clamp half-ring 11 and the flexible rubber pad 15. The second function is to increase the adaptability between the clamp structure and the trunk. The high deformability of the flexible rubber pad 15 can make up for the gap between the clamp structure and the trunk. The third function is to increase the adaptability of the longhorn beetle trapping box. Considering that the tree itself is still in the growth stage and its trunk diameter will continue to thicken at a slow rate, the deformability of the flexible rubber pad 15 can adapt to the growth rate of the trunk and reduce the inhibitory effect of the longhorn beetle trapping box on the tree when it is working.

[0041] The bottom of the fixing base 1 is provided with an annular groove 13, in which a longhorn beetle attractant can be placed. The longhorn beetle attractant used here is mainly a chemical attractant, which mainly simulates the sex pheromones released by adult longhorn beetles to attract adults in the mating period. Alternatively, a sugar-vinegar liquid made of brown sugar, vinegar, wine and water in a certain ratio (generally, the mass fraction ratio of the four is 1:4:1:16) can be used as a food attractant to attract adult beetles to feed. The purpose of designing the attraction structure is to attract longhorn beetles that gather on the outer surface of the tree trunk to achieve efficient capture. This design is also based on the activity habits of poplar longhorn beetles. Generally, longhorn beetles gather at the tips of branches. The larvae, which have not yet grown wings, can only survive by gnawing on the edges of leaves at the tips of branches. As the larvae gradually evolve into adults, they will gradually crawl towards the tree trunk and feed on it. During this period, the male and female longhorn beetles mate and then climb back to the treetops to lay eggs. After laying eggs, the adult longhorn beetles will fly to other trees to choose a new host. The newly hatched larvae will repeat the above process to reproduce. This application selects the tree trunk as the capture area to take advantage of the fact that longhorn beetle larvae need to replenish their energy from the tree trunk during their growth from larvae to adults, as well as their natural instinct to mate, in order to capture longhorn beetles and greatly improve the capture efficiency.

[0042] To allow the pheromone in the longhorn beetle trapping box to fully volatilize to the outside of the box and thus achieve the purpose of trapping the longhorn beetles, multiple honeycomb holes are processed on the annular support plate 12 and the bottom of the trapping chamber 2. This allows the pheromone in the pheromone to be dispersed to the longhorn beetle's activity area through the annular support plate 12, the trapping chamber 2, and the top cover 3. When the longhorn beetle receives the pheromone, it will gradually crawl into the trapping chamber 2 through the entry groove 33 on the top cover 3, thus achieving the purpose of trapping. The purpose of providing a sealing ring between the side wall baffle 14 and the opening of the annular groove 13 to prevent the odor from dissipating is also to increase the probability of the longhorn beetle crawling into the trapping chamber 2 from the top cover 3.

[0043] In this embodiment, the main method of disassembling and connecting the capture chamber 2 and the fixed base 1 is by plugging. Multiple plug holes are machined on the top of the clamp half ring 11. The plug holes can be round holes or strip holes. The capture chamber 2 is provided with an arc-shaped step that meets the clamp half ring 11. At the bottom of the arc-shaped step, there is a pin that cooperates with the plug hole. In order to ensure the smoothness of disassembly and connection, the size of the pin can be smaller than the size of the plug hole. This can ensure the stability of the capture chamber 2 installation and reduce the difficulty of plugging and connecting the two.

[0044] Specific Implementation Method Two: Combining Figures 8 to 10 This embodiment differs from specific embodiment one in that the inlet groove 33 is machined on the top of the cover 32, and the inner side of the cover 32 is provided with a reverse ramp to prevent the longhorn beetle from crawling outwards. Other components and connection methods are the same as in specific embodiment one.

[0045] This embodiment provides a tapered escape-proof top cover, characterized by an entry groove 33 located at the top of the cover body 32, allowing longhorn beetles to crawl into the capture chamber 2 only from the top of the beetle capture box. Furthermore, the reverse ramp on the inner side of the cover body 32 effectively prevents the longhorn beetles from crawling out of the capture box via the entry groove 33 along the inner wall of the cover body 32. The tapered design allows the longhorn beetles to crawl in while the narrow width of the entry groove 33 effectively prevents them from flying out, further suppressing their escape. Moreover, the tapered escape-proof top cover is inexpensive to manufacture, has a simple structure, is highly economical, and is suitable for mass production.

[0046] Specific implementation method three: Combining Figures 11 to 13This embodiment differs from specific embodiment one in that the entry groove 33 is machined on the outer wall of the cover 32. The outer wall of the cover 32 is composed of multiple rectangular walls sequentially spliced ​​along an arc trajectory. Each rectangular wall has a corresponding entry groove 33. A baffle 34 is installed on the inner side of each rectangular wall to prevent the longhorn beetle from crawling outwards, and the baffle 34 is correspondingly set with the entry groove 33. The top of the cover 32 is open, and a nylon mesh 35 is fixed at the top opening of the cover 32. Other components and connection methods are the same as in specific embodiment one.

[0047] This embodiment provides a baffle-type escape-prevention top cover, characterized in that the entry groove 33 is located on the side of the cover body 32, and the outer contour surface of the cover body 32 is a polygonal structure, with a baffle 34 corresponding to each side. The top of the baffle 34 is hinged to the inner side of the rectangular wall, and the baffle 34 is inclined towards the inside of the cover body 32. This ensures that the baffle 34 can be pushed open from the outside to the inside, but cannot be pushed open from the inside to the outside, effectively preventing the longhorn beetle from escaping through the entry groove 33. In order to cooperate with the baffle 34, an extension edge 311 is also provided on the inner side wall of the mounting groove 31. The extension edge 311 can support the end of the baffle 34. The top opening of the cover body 32 is sealed by a nylon mesh 35, which can effectively prevent the adult longhorn beetle from flying out from the top opening of the cover body 32 without hindering the emission of the attractant odor.

[0048] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0049] Working principle

[0050] This application provides a detachable poplar longhorn beetle trapping box. Before use, the various components are assembled according to the connection method described in Specific Embodiment 1, and the trapping box is fixed to the poplar trunk. The side wall baffle 14 located on the annular groove 13 is opened, and the prepared longhorn beetle attractant is placed into the annular groove 13. The side wall baffle 14 is then tightly closed onto the annular groove 13. When the scent emitted by the longhorn beetle attractant is released sequentially through the annular support plate 12, the trapping chamber 2, and the top cover 3 to the longhorn beetle's activity area, it can induce the longhorn beetles to enter the trapping chamber 2 along the entry groove 33 on the top cover 3 to achieve the capture of the longhorn beetles. Regularly, staff will inspect the longhorn beetle trapping boxes in the forest. When it is found that a large number of longhorn beetles have been captured in the trapping box, the trapping chamber 2 can be directly removed from the clamp half-ring 11, and a new trapping chamber 2 can be replaced to continue the capture work. The trapping chamber 2 containing longhorn beetles can be uniformly transported to a safe area for centralized processing of the captured longhorn beetles.

[0051] The trapping chamber 2 in this application can be made of transparent plastic sheet material, and its inner wall is coated with paint to increase the smoothness of the inner wall of the trapping chamber 2, preventing longhorn beetles from climbing. At the same time, the phototropism of longhorn beetles can be taken into account. A light source can be set in the annular groove 13 and lit at night. The light beam will be emitted to the nearby area through the trapping chamber 2, thereby attracting longhorn beetles to move towards the trapping device, thus increasing the trapping ability of longhorn beetles at night.
