[0002] Chestnut is an important economic forest tree species with a cultivation history of approximately 3,000 years. However, the chestnut borer (Ceratitis mollissima) is a major chestnut fruit borer, causing severe damage to the plant, with a damage rate exceeding 70%, severely impacting the development of the chestnut industry.

[0003] Existing technologies typically use physical and chemical control methods to reduce chestnut weevil infestations. Physical control primarily involves hot water immersion and electric heating, while chemical control primarily involves spraying different pesticides at different times of emergence to kill the pests. However, while these existing physical and chemical control methods can kill the pests to a certain extent, they can easily affect the natural ecological balance of chestnuts and cause environmental pollution. Summary of the Invention

[0004] The present invention provides a chestnut trapping device, which is used to solve the defects of existing physical and chemical control methods that easily affect the original ecological balance of chestnuts and easily cause environmental pollution.

[0006] An insect entrance is provided at the lower end of the insect attraction cover, and an insect exit is provided at the upper end of the insect attraction cover. The insect attraction cover has an initial state and a working state. In the initial state, the inner diameter of the insect attraction cover gradually decreases along the direction from the insect entrance to the insect exit. In the working state, one side of the insect entrance is circumferentially fixed to the tree trunk so that a passage for insects to enter is formed between the other side of the insect entrance and the tree trunk.

[0007] A collecting space is formed in the collector, and the lower end of the collector is covered on the upper end of the insect attractant cover to form a collecting groove between the lower end of the collector and the upper end of the insect attractant cover to prevent insects from escaping.

[0008] The attractant is located in the collecting space and above the insect outlet. The attractant includes a main body. The outer wall of the main body is provided with a spike-like protrusion so that the attractant is shaped like a chestnut with thorns. The attractant is made of a dark red material with a wavelength range of 625nm to 650nm, or the surface of the attractant is provided with a layer of dark red material with a wavelength range of 625nm to 650nm.

[0009] According to the chestnut-like insect trapping device provided by the present invention, the collector is a light-transmitting collector, the insect trap cover includes a guide tube and a light shield, the guide tube is sleeved on the light shield, the insect entrance is located at the lower end of the light shield, and the insect exit is located at the upper end of the light shield.

[0010] According to the chestnut elephant trapping device provided by the present invention, a plurality of slots are provided at intervals along the circumferential direction at the lower end of the collector, and a plurality of connecting plates are provided at intervals along the circumferential direction at the upper end of the guide cylinder, and the connecting plates are plugged into and fitted with the slots in a one-to-one correspondence.

[0011] According to the chestnut insect trapping device provided by the present invention, the insect trap cover further includes a metal support net, and the light shield is sleeved on the metal support net.

[0012] According to the chestnut-like elephant trapping device provided by the present invention, the inner wall of the lower end of the collector is provided with a first frosted surface, and the outer wall of the upper end of the guide tube is in contact with the first frosted surface.

[0013] The chestnut-like insect trapping device provided by the present invention also includes a rainproof cover, which is detachably connected to the upper end of the collector.

[0014] According to the chestnut elephant trapping device provided by the present invention, the rainproof cover is threadedly connected to the upper end of the collector; or, the outer wall of the upper end of the collector is provided with a second frosted surface, and the rainproof cover is clamped on the upper end of the rainproof cover through the second frosted surface.

[0015] According to the chestnut-eating trapping device provided by the present invention, a connecting rope is provided on the inner wall of the rainproof cover, and the connecting rope is connected to the attractant.

[0016] The chestnut-eating trapping device provided by the present invention also includes a fixing member, which is used to fix the collector to the outer wall of the tree trunk.

[0017] According to the chestnut elephant trapping device provided by the present invention, the fixing member is a fixing rope.

[0018] The chestnut beetle trapping device provided by the present invention is provided with an insect trap cover, a collector and an attractant. When in use, the device is fixed as a whole to a set height of a tree trunk, so that one side of the insect entrance is fixed to the tree trunk along the circumferential direction, and a channel for insects to enter is formed between the other side of the insect entrance and the tree trunk. Since the attractant is within the collection space and the attractant is a dark red, thorny chestnut shape with a wavelength range of 625nm to 650nm, according to the habit of chestnut beetles climbing tree trunks, when they sense the attractant, they will enter the insect trap cover along the above channel and then enter the collector through the insect outlet. Since a collection groove is formed between the lower end of the collector and the upper end of the insect trap cover to prevent insects from escaping, it is difficult for chestnut beetles to escape after entering the collection groove, thereby realizing the attraction-blocking-capture of adult chestnut beetles. The overall structure of the device is simple and the capture efficiency is high. In the process of use, no damage is caused to the tree trunk, no chemicals are introduced, and no pollution is caused to the environment.

[0034] The following combination Figures 1 to 7 The present invention provides a trapping device for trapping chestnut elephants.

[0035] See also Figures 1 to 3 As shown, the chestnut insect trapping device provided by the embodiment of the present invention includes: an insect trap cover 10, a collector 20 and an attractant 30.

[0036] An insect entrance is provided at the lower end of the insect trap 10, and an insect exit is provided at the upper end of the insect trap 10. The insect trap 10 has an initial state and an operating state. In the initial state, the inner diameter of the insect trap 10 gradually decreases along the direction from the insect entrance to the insect exit. In the operating state, one side of the insect entrance is fixed to the tree trunk 70 along the circumferential direction, so that a passage for insects to enter is formed between the other side of the insect entrance and the tree trunk 70.

[0037] A collecting space is formed in the collector 20 , and the lower end of the collector 20 is covered on the upper end of the insect trap 10 to form a collecting groove 240 between the lower end of the collector 20 and the upper end of the insect trap 10 to prevent insects from escaping.

[0038] The attractant 30 is located in the collection space and above the insect outlet. The attractant 30 includes a main body. The outer wall of the main body is provided with a spike-like protrusion so that the attractant 30 is shaped like a chestnut with thorns. The attractant 30 is made of a dark red material with a wavelength range of 625nm to 650nm, or the surface of the attractant 30 is provided with a dark red material layer with a wavelength range of 625nm to 650nm.

[0039] The present invention provides a trapping device for trapping insects, which comprises an insect trap cover 10, a collector 20 and an attractant 30. Figure 2 As shown, when in use, the entire device is fixed to a set height on a tree trunk 70, so that one side of the insect entrance is fixed to the tree trunk 70 along the circumference, and a passage for insects to enter is formed between the other side of the insect entrance and the tree trunk 70. Since the attractant 30 is within the collection space and the attractant 30 is a deep red, chestnut-shaped, thorny light with a wavelength range of 625nm to 650nm, according to the habit of chestnut weevils climbing tree trunks 70, when they sense the attractant 30, they will enter the insect trap 10 along the above-mentioned passage and then enter the collector 20 through the insect outlet. Because a collection groove 240 is formed between the lower end of the collector 20 and the upper end of the insect trap 10 to prevent insects from escaping, chestnut weevils find it difficult to escape after entering the collection groove 240, thereby achieving the attraction, isolation, and capture of adult chestnut weevils. The overall structure of the device is simple and the capture efficiency is high. During use, the tree trunk 70 is not damaged, and no chemicals are introduced, which will not pollute the environment.

[0040] See also Figure 1 and Figure 6 As shown, according to some embodiments of the present invention, the collector 20 is a light-transmitting collector, and the insect trap 10 includes a guide tube 110 and a light shield 120. The guide tube 110 is sleeved on the light shield 120, the insect entrance is located at the lower end of the light shield 120, and the insect exit is located at the upper end of the light shield 120.

[0041] By setting the collector 20 as a light-transmitting collector and providing a light shield 120, the phototropism of the real image can be utilized to further enhance the capturing capability of the device.

[0042] Specifically, in the working state, a passage for insects to enter is formed between the outer side of the insect entrance and the tree trunk 70. There is sufficient light at the entrance of the passage. When the insects enter the insect trap 10, the light inside the insect trap 10 is darker due to the shading effect of the light shield 120. The collector 20 maintains brighter light due to its light-transmitting design. The phototaxis of the insects prompts them to move towards the bright area, so the insects will enter the collector 20 through the insect exit.

[0043] The guide tube 110 and the light shield 120 can be clamped and fixed together via a connector 130 disposed on the top.

[0044] See also Figure 1 、 Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, a plurality of slots 210 are provided at circumferential intervals at the lower end of the collector 20, and a plurality of connecting plates 111 are provided at circumferential intervals at the upper end of the guide cylinder 110. The connecting plates 111 are plugged into and matched with the slots 210 in a one-to-one manner.

[0045] By providing a plurality of slots 210 at circumferential intervals at the lower end of the collector 20 and a plurality of connecting plates 111 (not shown in the figure) at circumferential intervals at the upper end of the guide cylinder 110, the connecting plates 111 are plugged into and fitted into the slots 210 in a one-to-one correspondence, thereby achieving a firm connection between the collector 20 and the guide cylinder 110, improving the overall stability of the device, preventing loosening or displacement during use, and facilitating assembly and disassembly.

[0046] As an example, in this embodiment, four slots 210 are provided at intervals along the circumferential direction at the lower end of the collector 20 , and four connecting plates 111 are provided at intervals along the circumferential direction at the upper end of the guide cylinder 110 .

[0047] See also Figure 3 As shown, according to some embodiments of the present invention, the insect trap 10 further includes a metal support net (not shown in the figure), and the light shield 120 is sleeved on the metal support net.

[0048] By providing a metal support net, the metal support net can be used to support and fix the sunshade 120. When in use, the plastic deformation effect of the metal support net can be used to fix the insect trap 10 to the tree trunk 70 in a set shape, and the shape of the insect trap 10 can be adjusted according to the shape of the tree trunk 70 to make it fit the tree trunk 70 more closely, ensuring that the insect trap 10 can be firmly installed on the surfaces of different trees. This not only improves the adaptability and stability of the device, but also enhances the convenience and durability of use, and avoids the insect trap 10 from being displaced by wind or other external forces during use.

[0049] See also Figure 6 As shown, according to some embodiments of the present invention, the lower inner wall of the collector 20 is provided with a first frosted surface 220 , and the upper outer wall of the guide tube 110 contacts the first frosted surface 220 .

[0050] By providing the first frosted surface 220 on the lower inner wall of the collector 20, the friction between the lower inner wall of the collector 20 and the upper outer wall of the guide cylinder 110 can be increased, thereby making the connection between the two more stable and preventing relative rotation.

[0051] Specifically, the first frosted surface 220 can be directly processed on the inner wall of the lower end of the collector 20 by using sandpaper.

[0052] See also Figure 1As shown, according to some embodiments of the present invention, the chestnut elephant trapping device also includes a rainproof cover 40, which is detachably connected to the upper end of the collector 20.

[0053] The rain cover 40 effectively protects the interior of the device from rainwater, ensuring its continued operation even in adverse weather conditions. This prevents rainwater from directly entering the collector 20, extending the lifespan of the trapping device. Furthermore, the rain cover 40 is detachably connected to the upper end of the collector 20, facilitating cleaning, maintenance, or replacement when necessary, enhancing the device's practicality and convenience.

[0054] According to some embodiments of the present invention, the rainproof cover 40 is threadedly connected to the upper end of the collector 20 .

[0055] By configuring the rain cover 40 and the upper end of the collector 20 to be threaded, a more secure and stable connection is achieved, preventing the rain cover 40 from loosening or falling off due to wind or external forces. Furthermore, the threaded connection facilitates quick installation and removal of the rain cover 40, allowing it to be easily disassembled for cleaning, maintenance, or replacement without the need for tools or laborious operation.

[0056] According to some embodiments of the present invention, the outer wall of the upper end of the collector 20 is provided with a second frosted surface 230 , and the rainproof cover 40 is clamped on the upper end of the rainproof cover 40 through the second frosted surface 230 .

[0057] By setting a second frosted surface 230 on the outer wall of the upper end of the collector 20, the friction between the rain cover 40 and the collector 20 can be enhanced, so that the rain cover 40 can be more firmly clamped on the upper end of the collector 20, preventing the rain cover 40 from sliding or loosening under the action of external force, thereby ensuring the stability of the device during use.

[0058] See also Figure 1 As shown, according to some embodiments of the present invention, a connecting rope 50 is provided on the inner wall of the rain cover 40 , and the connecting rope 50 is connected to the attractant 30 .

[0059] By arranging the connecting rope 50 on the inner wall, the attractor 30 can be connected and fixed by using the connecting rope 50, and the structure is simple and the connection method is convenient.

[0060] In a specific implementation, the connecting rope 50 can be made of a material with strong weather resistance, such as nylon rope, stainless steel wire rope, etc.

[0061] See also Figure 2 As shown, according to some embodiments of the present invention, the chestnut elephant trapping device further includes a fixing member 60, which is used to fix the collector 20 to the outer wall of the trunk 70.

[0062] By providing the fixing member 60 , the entire device can be firmly fixed to the outer wall of the trunk 70 through the collector 20 , ensuring that the entire device maintains a stable position during use and avoids displacement or loosening due to external forces.

[0063] See also Figure 2 As shown, according to some embodiments of the present invention, the fixing member 60 is a fixing rope.

[0064] By setting the fixing part 60 in the form of a fixing rope, the collector 20 can be tied and fixed to the outer wall of the trunk 70 during use. Compared with the hard fixing part 60, the fixing rope is more adaptable and can easily cope with trunks 70 of different diameters while avoiding excessive damage to the bark.

[0065] At the same time, when it is necessary to adjust the height of the entire device on the tree trunk 70, the fixing rope can be loosened to adjust the position of the entire device. After the adjustment is completed, the fixing rope can be tightened.

[0066] The following is a specific example of the chestnut trapping device provided by the present invention. Figures 1 to 6 shown.

[0067] In this example, the chestnut-like insect trapping device includes an insect trap 10, a collector 20, an attractant 30, a rain cover 40, and a fixing member 60. The collector 20 is a light-transmitting collector, the insect trap 10 includes a guide tube 110, a light shield 120, and a metal support net, and the fixing member 60 is a fixing rope.

[0068] The collector 20 is made of transparent, colorless polyethylene and is cylindrical, with two through-holes. It is 150 to 170 mm tall, 88 to 90 mm in diameter, and 2 to 3 mm thick. The upper outer wall of the collector 20 is frosted to form a first frosted surface 220, while the lower outer wall is frosted to form a second frosted surface 230 to increase friction and enhance connection stability. Four slots 210, each 12 to 20 mm long, are circumferentially spaced 10 to 15 mm from the bottom of the collector 20.

[0069] The guide tube 110 is made of transparent colorless polyethylene material and is conical in shape as a whole. The bottom diameter is 88-90mm, the top diameter is 15mm to 20mm, and the wall thickness is 2mm to 3mm. There are four connecting plates 111 with a length of 15mm to 20mm at a distance of 40mm to 45mm from the top of the guide tube 110.

[0070] The sunshade 120 is made of black polyethylene film, measuring 500mm to 550mm long and 200mm to 300mm wide. It includes a stainless steel support mesh (metal support mesh) measuring 500mm to 550mm long and 200mm to 300mm wide, making it easier for chestnuts to climb. Two iron hooks, 10mm to 15mm wide and 35mm to 45mm long, are located at the top of the sunshade 120, serving as connectors 130 to the guide tube 110.

[0071] The rainproof cover 40 is made of a transparent colorless polyethylene material, is dish-shaped, has a height of 15 mm to 16 mm, a diameter of 88 mm to 90 mm, and a wall thickness of 2 mm to 3 mm.

[0072] The fixing rope is made of rubber material, has a diameter of 1.5mm to 2mm, and a length of 500mm to 800mm.

[0073] The following describes the method of using the chestnut-like trapping device provided by the present invention. Figures 1 to 7 shown.

[0074] The chestnut weevil trapping device provided by the present invention is suitable for deployment beginning in mid-to-late July each year, before the weevil emerges from the ground, at a density of 50 to 55 traps per mu. The process is as follows: First, hang the attractant 30 from the inner wall of the rain cover 40 via a connecting rope 50 (20 to 30 mm long). Then, place the rain cover 40 over the top of the collector 20, positioning the attractant 30 within the collector 20. Insert the top end of the guide tube 110 inwardly into the bottom end of the collector 20, and insert each connecting plate 111 into the slot 210 at the bottom end of the collector 20. Then, fold the shade net into a cone with a top diameter of 10 to 15 mm and insert it into the guide tube 110. Finally, attach an iron hook to the guide tube 110. Finally, the chestnut weevil trapping device is placed on a tree trunk 70 30 cm to 50 cm above the ground, and the fixing rope is looped around the middle of the collector 20, about 75 mm to 85 mm from the upper end of the collector 20, so that the entire device remains stable.

[0075] After the device has been placed for a period of time (for example, it is checked every week), the number of chestnut weevils captured in the collector 20 is checked. According to the capture situation, the position of the chestnut weevils trapping device on the tree trunk 70 can be appropriately adjusted or replaced and placed on other chestnut trees to continuously trap and prevent chestnut weevils, thereby reducing the damage caused by chestnut weevils to chestnuts and ensuring the yield and quality of chestnuts.

[0076] In the present embodiment, the experiment was conducted in three experimental plots (area of 1.2 mu to 1.5 mu, with a row spacing of 3 m x 4 m). Fifty sets of chestnut beetle trapping devices were placed in each of the three experimental plots, and the chestnut beetles captured were collected and counted every two days. The experimental results are shown in Tables 1 and 2. Figure 7 shown.
