[0026] It should be understood that, in order to clearly show the contents therein, the drawings herein are not drawn to scale, and the same or similar reference numerals indicate the same or similar components or parts. In addition, it should be understood that any embodiments described in this application and the technical features included therein can be combined with each other.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-7As shown, a trapping device for fall armyworms comprises a first trapping mechanism and a second trapping mechanism slidably mounted on the top of the first trapping mechanism; the first trapping mechanism comprises a hollow first cylinder, the side of the first cylinder has an entrance, and a one-way insect entry assembly is installed at the entrance to ensure that the fall armyworms cannot escape once they enter; the first cylinder has a tray inside, and the tray is loaded with an attractant, which can emit pheromones that are very attractive to the fall armyworms, thereby effectively attracting them into the device. The second trapping mechanism comprises a hollow second cylinder, the second cylinder is slidably mounted on the top of the first cylinder, the top of the second cylinder has a trapping lamp, and the lamp has a strong attraction to the fall armyworms; the bottom of the second cylinder has an electric insect net, wherein, when the fall armyworms are attracted by the attractant to enter the first cylinder in one direction, they are attracted to the vicinity of the second cylinder by the trapping lamp and touch the electric insect net to be electrocuted and killed. The first cylinder and the second cylinder are both cylindrical, and the diameter of the first cylinder is larger than the diameter of the second cylinder. The entrance is located above the tray. The entrance is rectangular, with a length of 0.8cm-1.2cm and a width of 0.3cm-0.5cm. It can ensure the smooth entry of fall armyworms and effectively prevent other large insects from entering by mistake. Of course, the shape of the entrance can be adjusted according to actual needs, such as round, oval, diamond-shaped rectangle, etc. When trapping, just pull the second trapping mechanism out of the first trapping mechanism and fix it on top. When it needs to be stored or moved, just turn and press the second trapping mechanism into the first trapping mechanism, and the entire device can be quickly stored, which is convenient to carry and move to other locations for use.

[0029] Among them, attractants play a vital role in trapping fall armyworms. The attractants are neutral attractants, and their core ingredients are artificially synthesized sex pheromones. This sex pheromone is an important chemical substance used by fall armyworms for courtship communication in nature, and is composed of cis-9-tetradecene acetate and cis-7-dodecene acetate in a specific mass ratio. This neutral attractant should take into account multiple factors, including the biological characteristics, behavioral habits and environmental factors of fall armyworms. It has a high degree of specificity and attraction, and can accurately attract target insects to the trapping device without affecting other non-target insects.

[0030] like Figure 2-4As shown, the top of the first cylinder has an opening for installing the second cylinder, and sliders are provided on both sides of the bottom of the second cylinder. An annular groove is provided on the inner side of the opening. The shape of the slider matches the shape of the annular groove. The slider slides in the annular groove. Notches are provided on both sides of the bottom of the annular groove. Vertical slide rails are connected below the two notches, providing a moving path for the storage and deployment of the second cylinder. A blocking block is provided at the bottom of the vertical slide rail. When the second cylinder is stored, the slider is driven to slide in the annular groove by rotating the second cylinder. The slider reaches the notch and moves downward along the vertical slide rail, so that the second cylinder is sleeved inside the first cylinder. Among them, the height of the second cylinder is equal to the length of the vertical slide rail. When stored, the slider just rests on the blocking block to ensure that the second cylinder is stored in the designated position inside the first cylinder. Among them, when the trapping device needs to be deployed, first, the second cylinder is pulled upward, and the slider will slide upward in the vertical slide rail until the slider passes through the notch smoothly and reaches the annular groove. Next, rotate the second cylinder to drive the slider to slide in the annular groove, and finally the slider is clamped in the appropriate position in the annular groove. At this time, the second cylinder is successfully extended and fixed on the top of the first cylinder, completing the deployment of the trapping device. When the trapping device needs to be stored, just reverse the operation, that is, rotate the second cylinder to make the slider slide in the annular groove. When the slider reaches the notch, it will pass through the notch and be smoothly clamped in the vertical slide rail. Then, the slider slides downward along the vertical slide rail, driving the second cylinder to move downward, and finally fits inside the first cylinder. After storage is completed, the top of the second cylinder is flush with the top of the first cylinder.

[0031] like Figure 1 , 2As shown in Figure 7, the one-way insect entry assembly includes a flat plate, an insect entry opening is provided on the flat plate, the insect entry opening is connected to the entrance opening through a pipeline, a plurality of inclined baffles are provided on the inner side of the insect entry opening in the circumferential direction, and the plurality of inclined baffles together form a one-way insect entry opening, and the inclination direction of the plurality of inclined baffles is the same as the insect entry direction of the one-way insect entry opening, forming a natural guide, when the fall armyworm tries to enter, they will move along the inclination direction of the inclined baffles, and smoothly enter the interior of the device from the one-way insect entry opening, because the inclination direction of the inclined baffles is one-way, when the insects try to move in the reverse direction, they will encounter resistance in the opposite direction of the forward direction, and therefore cannot easily find the exit, thereby ensuring that the fall armyworm can only enter but not exit, and enter in one direction. A protective cover is provided on the outer side of the flat plate, which can prevent the external environment from interfering with the one-way insect entry opening. In this embodiment, the length of the insect entrance is 1 cm, the width is 0.4 cm, and the number of the entrances is four, corresponding to four one-way insect entrance components. Of course, the number of the entrances and the one-way insect entrance components can be adjusted as needed, such as one, two, six, etc. In areas with a high density of fall armyworms, the number of the entrances and the one-way insect entrance components can be appropriately increased to improve the trapping efficiency. The number of inclined baffles is four, and the four inclined baffles are circumferentially arranged on the inner side of the insect entrance, and the four inclined baffles form a trumpet-shaped structure. In addition, the position of the entrance is also related to the position of the attractant release. In an embodiment not shown, multiple entrances are circumferentially arranged on the side of the device at a certain interval, and are all in the same horizontal position. The tray loaded with the attractant is arranged at the center of the bottom of the device to ensure that each entrance can be evenly distributed with the attractant, thereby ensuring the utilization rate of each entrance and improving the overall trapping effect.

[0032] like Figure 2-5 As shown, the side of the first cylinder is also provided with an inspection door. The inspection door is used to clean the insect excrement, corpses and other debris inside the first cylinder, and to replenish the attractant.

[0033] like Figure 6 As shown, the inner wall of the second cylinder also has an annular sticky insect board. If the fall armyworm is not electrocuted by the electric insect net, it may pass through the electric insect net and enter the second cylinder. The annular sticky insect board can trap the fall armyworm for a second time, achieving double protection for killing. Under the interception of the electric insect net, most of the fall armyworms will be electrocuted to death, but some individuals may still escape. At this time, the annular sticky insect board in the second cylinder plays a vital role. The annular sticky insect board is made of high-efficiency sticky insect glue and special materials, and the surface is covered with sticky substances. When the fall armyworm contacts the annular sticky insect board, it will be firmly stuck and unable to escape, thereby effectively trapping the fall armyworm that has not been electrocuted for a second time, further improving the efficiency of insect control.

[0034] like Figure 4-6As shown, the top of the second cylinder has a cover, which can be opened to clean up the debris in the second cylinder, a solar panel is provided on the top of the cover, and the trapping lamp is located at the bottom of the cover. The second cylinder is a cylinder that passes through from top to bottom, the top of the second cylinder is threadedly connected to the cover, and the bottom of the second cylinder has a connecting port, through which the internal space of the first cylinder and the second cylinder are connected, and an electric insect net is provided at the connecting port. A connecting hole is provided in the middle of the solar panel, and a handle can be fixed at the connecting hole, and the handle is used to extract and store the second cylinder.

[0035] like Figure 6 As shown, the trapping lamp is an ultraviolet lamp with a wavelength of 365nm. The ultraviolet lamp has the best effect on attracting fall armyworms when the wavelength is 365nm. Fall armyworms are an insect with strong phototaxis and are very sensitive to light of a specific wavelength. When light of this wavelength shines on the compound eyes of the insect, it can stimulate its nervous system and cause it to have a strong flight reaction, so that it is attracted by the trapping lamp and guided to the electric insect net for killing. Light of this wavelength has strong penetrating power and can maintain a good trapping effect even at night or in foggy weather. In addition, the ultraviolet lamp has a long service life and low maintenance cost, which provides convenience for long-term use.

[0036] like Figure 1 and Figure 2 As shown, the bottom of the first cylinder is hinged with a plurality of supporting feet, so that the supporting feet can be folded and stored to the bottom of the first cylinder. Specifically, there are three supporting feet, which are evenly distributed at the bottom of the first cylinder. The supporting feet are hinged to the bottom of the first cylinder by hinges, so that the supporting feet can switch between unfolded and folded states. When the trapping device needs to be used, the supporting feet only need to be unfolded from the bottom of the first cylinder, and they will automatically lock in the unfolded position to provide support for the entire device. When the device needs to be moved or stored, the supporting feet can be folded back to the bottom of the first cylinder for quick storage, reducing space occupancy and facilitating transportation and storage. The top of the first cylinder has a handle, which is used to move and transfer the trapping device.

[0037] In an embodiment not shown, a battery is fixed to the bottom of the first cylinder, and the trapping lamp, solar panel and electric insect net are electrically connected to the battery respectively. As the core component of energy collection, the solar panel can continuously convert solar energy into electrical energy and store it in the battery. At night or when there is insufficient sunlight, the battery can continuously power the trapping lamp and the electric insect net to ensure the all-weather operation of the trapping device. At the same time, it also improves the efficiency of energy utilization and reduces the energy consumption cost of the device.

[0038] The working method of the utility model is as follows:

[0039] When the trapping device needs to be deployed, first, pull the second cylinder upward, and the slider will slide upward in the vertical slide rail until the slider passes through the notch and reaches the annular groove. Then, rotate the second cylinder to drive the slider to slide in the annular groove, and finally the slider is engaged in the appropriate position in the annular groove. At this time, the second cylinder is successfully extended and fixed above the first cylinder, completing the deployment of the trapping device.

[0040] When the fall armyworms are attracted by the attractant in the first cylinder, they will enter the first cylinder through the one-way insect inlet of the one-way insect inlet assembly. Due to the setting of the inclined baffle, the fall armyworms can only enter in one direction and cannot return to the outside. The fall armyworms entering the first cylinder will be attracted by the trapping lamp, and the fall armyworms will fly near the second cylinder. Specifically, the trapping lamp is an ultraviolet lamp with a wavelength of 365nm. When the fall armyworms touch the electric insect net at the bottom of the second cylinder, they will be electrocuted and killed. At the same time, the annular sticky insect plate on the inner wall of the second cylinder can also perform secondary trapping on the fall armyworms that have not been electrocuted. Over time, the attractant in the first cylinder may gradually be consumed and can be replenished through the inspection door. Similarly, if there are a large number of fall armyworms in the first cylinder, they can also be cleaned through the inspection door. During use, the entire trapping device can be conveniently moved by the handle to adapt to different environmental requirements.

[0041] When the trapping device needs to be stored, the operation is reversed, that is, the second cylinder is rotated to make the slider slide in the annular groove. When the slider reaches the notch, it passes through the notch and is smoothly engaged in the vertical slide rail. Then, the slider slides down along the vertical slide rail, driving the second cylinder to move downward, and finally fits inside the first cylinder. After storage is completed, the top of the second cylinder is flush with the top of the first cylinder.

[0042] In general, the utility model provides a trapping device for fall armyworms, which realizes efficient and convenient trapping and elimination functions, and is easy to carry and transfer. The device adopts a double-layer trapping mechanism, in which the first cylinder attracts fall armyworms through attractants, and ensures one-way entry of fall armyworms with the help of a one-way insect feeding component; the second cylinder uses a trapping lamp to attract fall armyworms to the electric insect net to achieve electric shock elimination. The first cylinder and the second cylinder are designed to slide, allowing the second cylinder to be stored in the first cylinder, which is easy to carry and transfer. The support feet hinged at the bottom and the handles on the top further enhance the stability and portability of the device, providing a comprehensive and effective solution for trapping fall armyworms.

[0043] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
