Description
Technical Field
[0001] This utility model relates to the field of pest control, specifically a device for the outdoor propagation and release of wheat moth parasitic wasps. Background Technology
[0002] In agricultural production, lepidopteran moths cause serious damage to crops. Currently, there are various methods for controlling lepidopteran moths. While chemical control has played an important role in the past, its long-term use has led to many problems, including increased pest resistance, pesticide residues, and environmental pollution. Physical control utilizes the phototaxis of noctuid moths, employing LED traps of different wavelengths, combined with insect sex pheromones, resulting in significant insecticidal effects. However, this method has limited effectiveness against larvae that have already laid eggs or are damaging crops.
[0003] Biological control, as a sustainable strategy, has attracted widespread attention due to its advantages in reducing or avoiding the negative problems of chemical control. The wheat moth parasitoid wasp, as a dominant parasitic wasp for many lepidopteran moths, has great potential in the field of biological control.
[0004] However, the use of braconid wasps to control lepidopteran pests in China is still in the preliminary research and application stage and has not yet been widely promoted. Currently used propagation devices rely primarily on the wasps' voluntary flight to induce them to emerge. This method is entirely governed by the wasps' own behavioral will; if they are unwilling to fly out due to unsuitable environment or poor physiological condition, it will directly lead to low propagation efficiency, and the entire process is poorly controllable. Alternatively, a driving rod can be used to tap the side wall, forcing the wasps to fly out through vibration. This method is also cumbersome, and the tapping force is difficult to control precisely, potentially causing physical damage to the wasps and affecting their survival and parasitic ability. Utility Model Content
[0005] The present invention aims to provide a device for the propagation and release of wheat moth parasitic wasps in the wild, so as to facilitate the propagation of wheat moth parasitic wasps and to gently encourage the wheat moth parasitic wasps to fly out of the device.
[0006] To solve the above technical problems, the specific solution adopted by this utility model is as follows: a device for the wild propagation and release of wheat moth parasitic wasps, including a box, two layers of partition nets spaced apart inside the box, and two layers of partition plates spaced apart between the two layers of partition nets;
[0007] The partition is a foldable panel, and the box is equipped with a control mechanism that can control the extension and retraction of the partition. The control mechanism includes two winding wheels on one side of the box and a reversing wheel on the opposite side of the box. One end of the traction rope is wound around one of the winding wheels, and the other end is wound around the other winding wheel after passing over the reversing wheel. One end of the partition is fixed to the traction rope, and the other end is fixed to the inner wall of the box.
[0008] A honeycomb mesh is installed on the side wall of the box between the two partition boards.
[0009] As a further optimization of the above technical solution, a control mechanism is installed on each partition plate, and the vertical projection of the traction rope of the control mechanism on the partition plate is located on the center line of the partition plate; or, two control mechanisms are installed on each partition plate, the traction ropes of the two control mechanisms are parallel to each other, and the vertical projections of the traction ropes of the two control mechanisms on the partition plate are symmetrical on both sides of the center line of the partition plate.
[0010] As a further optimization of the above technical solution, a support rod is provided at each end of the expansion and contraction direction of the partition plate. One support rod is fixed to the inner wall of the box, and the other support rod has a through hole for the traction rope to pass through and be fixed.
[0011] As a further optimization of the above technical solution, multiple creases are arranged parallel to each other on the partition plate, and the length direction of the creases is perpendicular to the length direction of the traction rope.
[0012] As a further optimization of the above technical solution, multiple limiting posts are spaced along the outer edge of the plate along the extension and retraction direction of the partition plate, and a strip-shaped limiting groove is opened on the inner wall of the box for the insertion of the limiting posts.
[0013] As a further optimization of the above technical solution, a roller is installed at the end of the limiting post away from the partition plate, and the cross-section of the strip limiting groove is T-shaped.
[0014] As a further optimization of the above technical solution, multiple creases are arranged parallel to each other on the partition plate. The creases include V-shaped creases with the opening facing upwards and V-shaped creases with the opening facing downwards, and the two types of creases are distributed alternately. Multiple limiting posts are arranged at intervals along the outer edge of the plate along the extension and contraction direction of the partition plate. The limiting posts are arranged in pairs and located at both ends of the V-shaped creases with the opening facing downwards.
[0015] As a further optimization of the above technical solution, both the winding wheel and the reversing wheel are fixed to the outer wall of the housing.
[0016] As a further optimization of the above technical solution, the beehive mesh panels are two pieces and are set on opposite sides of the box.
[0017] As a further optimization of the above technical solution, the separator is made of mesh silk yarn with a mesh diameter of 0.9mm.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. This utility model, by setting a partition net inside the box, allows the maize moth parasitic wasps to pass freely after propagation while restricting the escape of the host. By setting the partition plate as a retractable plate, when both partition plates are in the extended state, a release zone is formed between the two partition plates, and two propagation zones are formed on the outside of the two partition plates, allowing the larvae and eggs of the maize moth parasitic wasps to grow in the propagation zone. When the maize moth parasitic wasps emerge and grow to the release stage, the two partition plates are retracted, the two propagation zones are connected, and the maize moth parasitic wasps can enter the release zone and fly out from the release net plate on the side wall of the box.
[0020] 2. The operation is simple: the extension and folding of the partition is controlled by pulling the traction rope. When the adult insects are released, the extension and folding of the partition is controlled to disturb the wheat moth wasps in the box and make them fly out of the box.
[0021] 3. By controlling the folded partition to be located below the traction rope, one of the folded partitions is located in the bee release area. The side wall of the bee release area is equipped with a bee release net. Natural wind can enter the box through the bee release net, causing the folded partition to shake and prompting the wheat moth parasitic wasps to fly out of the box. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.
[0029] like Figure 1-3 As shown, this utility model discloses a device for the outdoor propagation and release of wheat moth parasitic wasps, including a box 1, two layers of partition nets 7 spaced apart inside the box 1, and two layers of partition plates 3 spaced apart between the two layers of partition nets 7. The box 1 has a rectangular structure and is made of lightweight, anti-corrosion wood or high-strength plastic, and its size can be set according to the needs of outdoor operations.
[0030] In use, the box 1 is placed vertically, and the two layers of partition nets 7 and two layers of partition plates 3 are placed horizontally inside the box 1. The partition nets 7 and partition plates 3 are parallel to each other. The upper partition plate 3, the top of the box and its surrounding side walls enclose a propagation area 2, the lower partition plate 3, the bottom of the box and its surrounding side walls enclose a propagation area 2, and the two layers of partition plates 3 and their surrounding side walls enclose a bee release area 5. The two partition nets 7 are respectively placed in the two propagation areas 2.
[0031] Feed inlets are provided on the side walls of the box 1 above the upper partition net 7 and below the lower partition net 7, and are fitted with hinged covers. The covers are connected to the box 1 via hinges and are equipped with a snap-locking structure to ensure the airtightness of the box 1 during the propagation process. Hosts carrying *Pteris vittata* are fed into the box 1 through the two feed inlets. The host in the upper propagation area 2 is placed on the partition net 7, and the host in the lower propagation area 2 is placed at the bottom of the box. *Pteris vittata* completes its emergence, growth, and reproduction processes in the corresponding propagation area 2.
[0032] The separating mesh 7 is made of mesh silk yarn, a material with good air permeability and flexibility, and is unlikely to cause physical damage to the wheat moth parasitic wasps. The mesh size of the separating mesh 7 is 0.9mm, which allows adult wheat moth parasitic wasps to pass through freely while effectively restricting the escape of the host, ensuring the stable progress of the reproduction process. When the wheat moth parasitic wasps emerge and grow to the release stage, the two reproduction areas 2 are connected, allowing the wheat moth parasitic wasps to enter the release area and fly out from the release mesh plate 4 on the side wall of the box 1.
[0033] Specifically, the two propagation zones 2 are connected by controlling the folding of the partition plate 3. The partition plate 3 is a foldable plate, made of thin plastic sheet or coated paperboard, possessing a certain degree of rigidity and flexibility, facilitating folding and extension. A control mechanism 8 is installed on the housing 1 to control the extension and retraction of the partition plate 3; the control mechanism 8 includes two winding wheels 801 located on one side of the housing 1 and a reversing wheel 802 located on the opposite side of the housing 1. Both the winding wheels 801 and the reversing wheel 802 are fixed to the outer wall of the housing 1 by mounting bases 6, which are bolted to the housing 1 for easy disassembly and maintenance. The winding wheels 801 are manual winding wheels with crank handles, facilitating manual control by the operator. Anti-slip textures can be provided on the crank handle to improve the operating feel. The traction rope 803 is made of high-strength nylon rope, which is wear-resistant and not easy to break. One end of the rope is wound on one of the winding wheels 801, and the other end is wound on another winding wheel 801 after passing over the reversing wheel 802. The traction rope 803 can be wound and released by rotating the winding wheel 801, thereby controlling the state of the partition plate 3.
[0034] One end of the partition plate 3 is fixed to the traction rope 803, and the other end is fixed to the inner wall of the box 1. Each partition plate 3 is equipped with a control mechanism 8. The vertical projection of the traction rope 803 of the control mechanism 8 onto the partition plate 3 is located on the center line of the partition plate 3. By pulling the traction rope 803, the partition plate 3 can be folded or unfolded, which is simple to operate. This setting can ensure that the partition plate 3 is subjected to uniform force during folding and unfolding, avoiding skewing or jamming.
[0035] A support rod 9 is provided at each end of the partition plate 3 in the telescopic direction. The support rod 9 is made of lightweight metal or rigid plastic and serves to enhance the strength of the ends of the partition plate 3. One support rod 9 is fixed to the inner wall of the box 1 by welding or bolting, and the other support rod 9 has a through hole for the traction rope 803 to pass through and be fixed. The through hole is located in the middle of the support rod 9. After the traction rope 803 passes through the support rod 9, it is fixed by knotting or setting a rope buckle to ensure that the traction rope 803 can effectively drive the partition plate 3 to move.
[0036] like Figure 4 As shown, to enable the partition plate 3 to fold at a specific angle, multiple parallel creases 12 are provided on the partition plate 3, with the length direction of the creases 12 perpendicular to the length direction of the traction rope 803. The spacing of the creases 12 can be set according to the size of the partition plate 3 and the required compactness after folding. The creases 12 include V-shaped creases 12 with openings facing upwards and V-shaped creases 12 with openings facing downwards, and the two types of creases 12 are distributed alternately. This design allows the partition plate 3 to fold in a zigzag pattern, greatly reducing the volume after folding while ensuring the smoothness of the folding process.
[0037] like Figure 4 , 5As shown, multiple limiting posts 10 are spaced apart along the outer edge of the partition plate 3 in the direction of extension and retraction. The limiting posts 10 have a cylindrical structure and are made of the same material as the support rod 9. A strip-shaped limiting groove 11 is provided on the inner wall of the box for the insertion of the limiting posts 10. During the folding or unfolding of the partition plate 3, the limiting posts 10 remain within the limiting groove 11 to prevent the partition plate 3 from shifting vertically and to ensure that the partition plate 3 moves along a predetermined trajectory. The limiting posts 10 are arranged in pairs at both ends of the creases 12, with a pair of limiting posts 10 placed every other crease 12. Specifically, the limiting posts 10 are located at both ends of the downward-facing V-shaped creases 12. This layout ensures that the folded partition plate 3 is located below the traction rope 803, facilitating subsequent natural wind action.
[0038] To ensure smooth sliding of the limiting post 10 within the strip-shaped limiting groove 11, a roller is installed at the end of the limiting post 10 furthest from the partition plate 3. The inclined surface of the strip-shaped limiting groove 11 is T-shaped, including an enlarged inner cavity and a channel connecting the inner cavity to the outside. In use, the roller is located in the enlarged inner cavity of the T-shaped groove, and the limiting post 10 is located within the channel of the strip-shaped limiting groove 11. This structural design not only reduces the resistance during the state switching of the partition plate 3 through the rolling of the roller, making operation more effortless, but also constrains the roller through the enlarged inner cavity, effectively preventing the limiting post 10 from detaching from the limiting groove 11 and ensuring the stability of the device.
[0039] Release mesh panels 4 are installed on the side wall of the box 1 between the two partition panels 3. There are two release mesh panels 4, which are set on opposite sides of the box 1. The mesh size is slightly larger than the size of the adult parasitic wasp, ensuring that the parasitic wasp can fly out smoothly, while preventing large insects or debris from entering the box 1. The two release mesh panels 4 are set opposite each other, which is conducive to the formation of air convection. Natural wind can enter the box 1 from one release mesh panel 4, causing the folded partition panels 3 to shake slightly, further disturbing and prompting the parasitic wasps to fly out from the release mesh panel 4 on the other side, thus improving the release efficiency.
[0040] In other embodiments of this utility model, depending on actual needs, two control mechanisms 8 can also be installed on each partition plate 3. The traction ropes 803 of the two control mechanisms 8 are parallel to each other, and their vertical projections on the partition plate 3 are symmetrically distributed on both sides of the center line of the partition plate 3. This dual control mechanism 8 setting can further improve the stability and reliability of the state switching of the partition plate 3, and is suitable for partition plates 3 with larger sizes.
[0041] The working process of this utility model is as follows:
[0042] Propagation stage: Hosts carrying eggs or larvae of the wheat moth parasitic wasp are placed into two propagation zones 2 through the feed inlet. At this time, the partition plate 3 is extended, and the two propagation zones 2 are independent of each other. The wheat moth parasitic wasps grow and develop within the propagation zones 2 using the host. The partition net 7 restricts the escape of the host while allowing the adult wheat moth parasitic wasps to move around.
[0043] Release preparation stage: When the wheat moth parasitic wasps grow to the release stage, the operator rotates the winding wheel 801, and the traction rope 803 drives the partition plate 3 to fold, so that the two propagation areas 2 are connected, and the wheat moth parasitic wasps can enter the release area 5 from the propagation area 2.
[0044] Release phase: The folded partition 3 is located in the bee release area 5. Natural wind enters the box 1 through the bee release net 4, causing the folded partition 3 to shake, creating a gentle disturbance to the wheat moth corydalis wasps, prompting them to fly out of the box 1 from the bee release net 4, thus completing the release process.
[0045] In addition, during the release phase, the state switching between the extension and folding of the partition plate 3 can be controlled by pulling the traction rope 803, which is simple to operate; when the adult insects are released, the state switching between the extension and folding of the partition plate 3 can be controlled to disturb the wheat moth parasitic wasps in the box 1 and cause them to fly out of the box.
[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
