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

[0007] The collector has a collection space inside, and the lower end of the collector covers the upper end of the insect-attracting cover to form a collection groove between the lower end of the collector and the upper end of the insect-attracting cover to prevent insects from escaping.

[0008] The attractant is located within the collection space and above the insect exit. The attractant includes a main body with spiked protrusions on the outer wall of the main body to make the attractant resemble a spiky chestnut. The attractant is made of a deep red material with a wavelength range of 625nm to 650nm, or the surface of the attractant has a layer of deep red material with a wavelength range of 625nm to 650nm.

[0009] According to the chestnut weevil trapping device provided by this utility model, the collector is a light-transmitting collector, the insect trapping cover includes a guide tube and a light-shielding cover, the guide tube is sleeved on the light-shielding cover, the insect inlet is located at the lower end of the light-shielding cover, and the insect outlet is located at the upper end of the light-shielding cover.

In use, the entire device is fixed to a predetermined height on the tree trunk, with one side of the insect entrance fixed circumferentially to the trunk. A passage is formed between the other side of the insect entrance and the trunk, allowing insects to enter. Because the attractant is a deep red, chestnut-shaped device with a wavelength range of 625nm to 650nm, it is designed to attract the chestnut weevil's climbing habits. Upon sensing the attractant, the weevil will enter the hood along the passage and then exit through the insect exit into the collector. Since a collection groove is formed between the lower end of the collector and the upper end of the hood to prevent insect escape, the weevil has difficulty escaping once inside. This achieves the attraction-blocking-capture of adult chestnut weevils. The device has a simple overall structure, high capture efficiency, and does not damage the tree trunk during use, nor does it introduce chemicals or pollute the environment.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0035] The following is combined Figures 1 to 7 This invention describes the chestnut pheromone trapping device provided by this utility model.

[0036] See Figures 1 to 3 As shown, the chestnut worm trapping device provided in this embodiment of the present invention includes: a worm trap 10, a collector 20, and a lure 30.

[0037] The insect trap 10 has an insect entrance at the lower end and an insect exit at the upper end. The insect trap 10 has an initial state and a working 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 working state, one side of the insect entrance is fixed to the tree trunk 70 circumferentially so that a passage for insects to enter is formed between the other side of the insect entrance and the tree trunk 70.

[0038] The collector 20 has a collection space inside, and the lower end of the collector 20 covers the upper end of the insect trap 10 to form a collection trough 240 between the lower end of the collector 20 and the upper end of the insect trap 10 to prevent insects from escaping.

[0039] The attractant 30 is located in the collection space and above the insect exit. The attractant 30 includes a main body with spike-like protrusions on the outer wall of the main body to make the attractant 30 resemble a spiky chestnut. The attractant 30 is made of a deep red material with a wavelength range of 625nm to 650nm, or the surface of the attractant 30 is covered with a layer of deep red material with a wavelength range of 625nm to 650nm.

[0040] The chestnut weevil trapping device provided by this utility model consists of an insect-attracting cover 10, a collector 20, and an attractant 30. (See also...) Figure 2 As shown, during use, the entire device is fixed at a set height on the tree trunk 70, with one side of the insect entrance fixed circumferentially to the tree trunk 70, and a channel for insects to enter is formed between the other side of the insect entrance and the tree trunk 70. Since the attractant 30 is a deep red, chestnut-shaped insect with a wavelength range of 625nm to 650nm, based on the habit of chestnut weevils climbing the tree trunk 70, when they sense the attractant 30, they will enter the insect trap 10 along the aforementioned channel, and then enter the collector 20 through the insect exit. Since 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, it is difficult for chestnut weevils to escape after entering the collection groove 240. Thus, the attraction-blocking-capture of adult chestnut weevils is achieved. The overall structure of the device is simple, the capture efficiency is high, and it will not damage the tree trunk 70 during use, nor will it introduce chemicals or cause environmental pollution.

[0041] See 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-attracting cover 10 includes a guide tube 110 and a light-shielding cover 120. The guide tube 110 is fitted onto the light-shielding cover 120, the insect inlet is located at the lower end of the light-shielding cover 120, and the insect outlet is located at the upper end of the light-shielding cover 120.

[0042] By setting the collector 20 as a light-transmitting collector and setting the light shield 120, the phototaxis of the chestnut elephant can be utilized to further enhance the capture capability of the device.

[0043] Specifically, in the working state, a passage is formed between the outer side of the insect entrance and the tree trunk 70, allowing insects to enter. The entrance of the passage is well lit. When insects enter the insect trap 10, the light inside the insect trap 10 is relatively dim due to the light-blocking effect of the light shield 120, while the collector 20 maintains relatively bright light due to its light-transmitting design. The insects' phototaxis causes them to move towards the bright area, so the insects will enter the collector 20 through the insect exit.

[0044] The guide tube 110 and the light shield 120 can be clamped and fixed together by the connector 130 provided at the top.

[0045] See Figure 1 , Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, the lower end of the collector 20 is provided with a plurality of slots 210 spaced apart along the circumference, and the upper end of the guide tube 110 is provided with a plurality of connecting plates 111 spaced apart along the circumference. The connecting plates 111 and the slots 210 are inserted and engaged in a one-to-one correspondence.

[0046] By providing multiple slots 210 at circumferential intervals at the lower end of the collector 20 and multiple connecting plates 111 (not shown in the figure) at circumferential intervals at the upper end of the guide tube 110, the connecting plates 111 and slots 210 are inserted and matched one by one, which can realize the stable connection between the collector 20 and the guide tube 110, improve the overall stability of the device, prevent loosening or displacement during use, and facilitate assembly and disassembly.

[0047] As an example, in this embodiment, the collector 20 has four slots 210 spaced circumferentially at its lower end, and the guide tube 110 has four connecting plates 111 spaced circumferentially at its upper end.

[0048] See Figure 3 As shown, according to some embodiments of the present invention, the insect trap 10 also includes a metal support net (not shown in the figure), and the light shield 120 is fitted onto the metal support net.

[0049] By setting up a metal support net, the light-blocking cover 120 can be supported and fixed. In use, the shaping and deformation of the metal support net can be used to fix the insect-attracting cover 10 to the tree trunk 70 in a set shape. The shape of the insect-attracting cover 10 can be adjusted according to the shape of the tree trunk 70 to make it fit the tree trunk 70 better. This ensures that the insect-attracting cover 10 can be stably installed on different tree surfaces. This not only improves the adaptability and stability of the device, but also enhances the convenience and durability of use, and prevents the insect-attracting cover 10 from shifting due to wind or other external forces during use.

[0050] See 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 is in contact with the first frosted surface 220.

[0051] By providing a 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.

[0052] Specifically, the first frosted surface 220 can be directly sanded on the lower inner wall of the collector 20.

[0053] See Figure 1As shown, according to some embodiments of the present invention, the chestnut elephant trapping device also includes a rain cover 40, which is detachably connected to the upper end of the collector 20.

[0054] By providing a rain cover 40, the internal components of the device can be effectively protected from rainwater corrosion, ensuring that the device can still function normally under harsh weather conditions. The rain cover 40 also 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 part of the collector 20, facilitating cleaning, maintenance, or replacement when needed, increasing the practicality and convenience of the device.

[0055] According to some embodiments of the present invention, the rain cover 40 is threadedly connected to the upper end of the collector 20.

[0056] By configuring the rain cover 40 and the upper end of the collector 20 with a threaded connection, a more secure and stable connection can be achieved, preventing the rain cover 40 from loosening or falling off under wind or external force. At the same time, the threaded connection also facilitates the quick installation and removal of the rain cover 40, allowing for easy disassembly for cleaning, maintenance, or replacement without the need for tools or strenuous operation.

[0057] According to some embodiments of the present invention, the upper outer wall of the collector 20 is provided with a second frosted surface 230, and the rain cover 40 is secured to the upper end of the rain cover 40 through the second frosted surface 230.

[0058] By providing a second frosted surface 230 on the upper outer wall of the collector 20, the friction between the rain cover 40 and the collector 20 can be enhanced, making the rain cover 40 more firmly fixed on the upper end of the collector 20, preventing the rain cover 40 from sliding or loosening under external force, and ensuring the stability of the device during use.

[0059] See Figure 1 As shown, according to some embodiments of the present invention, the inner wall of the rain cover 40 is provided with a connecting rope 50, which is connected to the lure 30.

[0060] By setting a connecting rope 50 on the inner wall, the lure 30 can be connected and fixed using the connecting rope 50. Its structure is simple and the connection method is convenient.

[0061] In practice, the connecting rope 50 can be made of materials with strong weather resistance, such as nylon rope or stainless steel wire rope.

[0062] See 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.

[0063] By setting the fastener 60, the entire device can be firmly fixed to the outer wall of the trunk 70 by the collector 20, ensuring that the entire device maintains a stable position during use and avoiding displacement or loosening caused by external forces.

[0064] See Figure 2 As shown, according to some embodiments of the present invention, the fixing member 60 is a fixing rope.

[0065] By setting the fixing member 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 rigid fixing member 60, the fixing rope is more adaptable and can easily cope with trunks 70 of different diameters, while avoiding excessive damage to the bark.

[0066] Meanwhile, when it is necessary to adjust the height of the entire device on the tree trunk, 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.

[0067] The following is a specific example of the chestnut pheromone trapping device provided by this utility model. (See attached image) Figures 1 to 6 As shown.

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.

[0069] The collector 20 is made of transparent, colorless polyethylene material, and is cylindrical in shape with two through sides. It has a height of 150mm to 170mm, a diameter of 88mm to 90mm, and a wall thickness of 2mm to 3mm. The upper outer wall of the collector 20 has a first frosted surface 220, and the lower outer wall has a second frosted surface 230, to increase friction and improve connection stability. The collector 20 has four slots 210, each 12mm to 20mm long, spaced circumferentially at a distance of 10mm to 15mm from the bottom.

[0070] The guide tube 110 is made of transparent colorless polyethylene material and is cone-shaped with a bottom diameter of 88-90 mm, a top diameter of 15 mm to 20 mm, and a wall thickness of 2 mm to 3 mm. It has four connecting plates 111 with a length of 15 mm to 20 mm at a distance of 40 mm to 45 mm from the top of the guide tube 110.

[0071] The light shield 120 is made of black polyethylene film, measuring 500mm to 550mm in length and 200mm to 300mm in width. It includes an internal stainless steel support mesh (metal support mesh), also 500mm to 550mm in length and 200mm to 300mm in width, to facilitate climbing by chestnut elephants. The top of the light shield 120 has two iron hooks, 10mm to 15mm wide and 35mm to 45mm long, serving as connectors 130 to the guide tube 110.

[0072] The rain cover 40 is made of transparent, colorless polyethylene material, is dish-shaped, 15mm to 16mm high, 88mm to 90mm in diameter, and 2mm to 3mm thick.

[0073] The fixing rope is made of rubber material, with a diameter of 1.5mm to 2mm and a length of 500mm to 800mm.

[0074] The following describes the method of using the chestnut shrike trapping device provided by this utility model. (See attached image.) Figures 1 to 7 As shown.

[0075] The chestnut weevil trapping device provided by this utility model is suitable for deployment starting in mid-to-late July each year before the chestnut weevil emerges from the soil, with a deployment density of 50 to 55 individuals per acre. The process is as follows: First, the attractant 30 is suspended from the inner wall of the rain cover 40 by a connecting rope 50 with a length of 20mm to 30mm. Then, the rain cover 40 is placed over the upper end of the collector 20, so that the attractant 30 is located inside the collector 20. The top of the guide tube 110 is inserted inward into the lower end of the collector 20, and each connecting plate 111 is inserted into the slot 210 at the bottom of the collector 20. Finally, the light-shielding net is folded into a cone with a top diameter of 10mm to 15mm and inserted into the guide tube 110, and the iron hook is hung on the guide tube 110. Finally, place the chestnut elephant trapping device on the tree trunk 70, which is 30cm to 50cm above the ground, and attach the fixing rope to the middle of the collector 20, about 75mm to 85mm from the top of the collector 20, to keep the device stable.

[0076] After the device has been in place for a period of time (e.g., checked weekly), check the number of chestnut weevils captured in collector 20.
