Description

Technical Field

[0001] The utility model relates to the technical field of insect breeding devices, in particular to an artificial feeding and breeding device for Pachycrepoideus vindemmiae Background Technique

[0002] During the cultivation of pest-infected sea buckthorn collected from sea buckthorn forests in Xinjiang Uygur Autonomous Region, it was found that Pachycrepoideus vindemmiae is a dominant parasitic natural enemy of Rhagoletis batava. Through long-term research, the biological characteristics of Pachycrepoideus vindemmiae have been deeply understood, and on this basis, artificial breeding methods have been explored, making it possible to control Rhagoletis batava with Pachycrepoideus vindemmiae.

[0003] Patent document CN116897891A discloses a method for raising Drosophila parasitic wasps and a raising and propagation device, and the protected claim "comprises the following steps: (1) enabling adult Drosophila to lay eggs on a Drosophila culture medium, collecting the eggs, and culturing them until they pupate into larvae; (2) when the Drosophila pupae in step (1) develop into 2-day-old pupae, inoculating the parasitic wasps 24 hours later and then removing the Drosophila culture medium; (3) collecting the Drosophila pupae parasitized by the parasitic wasps and continuing to culture; (4) removing the unparasitized Drosophila adults; (5) collecting the parasitized Drosophila pupae before the parasitic wasps emerge; (6) after the parasitic wasps emerge, performing cryogenic treatment and quickly collecting the adult wasps to preserve the wasp species. The raising method of the present invention is simple and easy to implement, requires less space for raising, has a lower cost, and can continuously breed Drosophila parasitic wasps. The raising method of the present invention can make the emergence rate of Diachasmimorpha longicaudata reach 70.25%", but the device used in this method is a modified ordinary insect breeding cage. Since it is impossible to isolate house flies and parasitic wasps, after the parasitic wasps mature, they will leave the host and fly around. It is not easy to clearly observe them with the naked eye in the insect breeding cage in the breeding room, and it is difficult to capture a sufficient number of parasitic wasps by hand or conventional tools, resulting in a poor breeding effect for the parasitic wasps.

Specific embodiments

[0024] The following will cooperate with the accompanying drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0025] Embodiment 1

[0026] Referring to Figures 1 - 5 , this embodiment proposes an artificial breeding device for Nasonia vitripennis. Through the setting of the isolation device 2, the problem that the parasitoid flies away from the host after maturity and it is difficult for conventional tools to capture a sufficient number of parasitoids, resulting in poor breeding effect of the parasitoid, is solved. The device includes a device housing 1, which is made of transparent acrylic plastic material for easy observation of the parasitoid parasitism behavior. A base 6 is fixedly installed at the bottom of the device housing 1, and a plurality of groups of triangular grooves 7 are evenly opened on the base 6. An isolation device 2 for isolating house flies and parasitoids is installed inside the device housing 1, and an adjustment device 3 for adjusting the size of the isolation area is installed on the isolation device 2. The device housing is divided into four areas by the isolation device 2, which is convenient for capturing a sufficient number of parasitoids and results in a better breeding effect of the parasitoids. By controlling the size of the parasitoid breeding area and the house fly breeding area through the adjustment device 3, the situation of the house flies and parasitoids escaping during separation can be avoided;

[0027] The isolation device 2 includes a first baffle 21 fixedly installed in the device housing 1. A connection groove 22 is formed on the first baffle 21. A rotating column 23 is rotatably installed in the connection groove 22. Two groups of symmetric second baffles 24 are fixedly installed on the rotating column 23. The interior of the device housing 1 is divided into four areas by the first baffle 21 and the second baffles 24, namely the Nasonia vitripennis breeding area for housefly pupae, the housefly pupa breeding area, the housefly adult breeding area, and the housefly larva breeding area, so as to isolate houseflies and parasitic wasps, avoiding the situation that after the parasitic wasps mature, they will leave the host and fly around, making it difficult for conventional tools to capture a sufficient number of parasitic wasps, resulting in poor breeding effect of parasitic wasps.

[0028] Embodiment 2

[0029] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the drawback that after the parasitic wasps mature, they will leave the host and fly around, making it difficult for conventional tools to capture a sufficient number of parasitic wasps, resulting in poor breeding effect of parasitic wasps. Since the breeding areas for houseflies and parasitic wasps are relatively large, when separating houseflies and parasitic wasps, there will be a situation where houseflies and parasitic wasps escape, affecting the breeding of Nasonia vitripennis.

[0030] Refer to Figures 1 - 5 , the adjusting device 3 includes a damping rotating shaft 31 fixedly installed on the rotating column 23. One end of the damping rotating shaft 31 passes through the device housing 1 and extends to its outside to prevent the second baffle 24 from rotating when the knob 32 is accidentally touched, affecting the isolation of houseflies and parasitic wasps. A knob 32 is fixedly installed at the top of the damping rotating shaft 31. Rotating the knob 32 drives the rotating column 23 connected to the damping rotating shaft 31 to rotate. The rotation of the rotating column 23 drives the second baffle 24 to rotate, which is used to adjust the area sizes of the Nasonia vitripennis breeding area for housefly pupae and the housefly adult breeding area, making its cross-section the same size as the cross-section of the triangular box 4, facilitating the collection of houseflies and parasitic wasps through the triangular box 4, and avoiding the situation that houseflies and parasitic wasps escape when separating houseflies and parasitic wasps.

[0031] A triangular box 4 is slidably installed in the triangular groove 7. A box cover 41 is slidably installed on the triangular box 4. A handle 42 is fixedly installed on the triangular box 4. A pull rod 43 is fixedly installed on the box cover 41. Since the bred insects have phototaxis, the box cover 41 is divided into four types: transparent with holes, transparent without holes, opaque with holes, and opaque without holes. The setting of the holes enables houseflies and Nasonia vitripennis for housefly pupae to be bred in the triangular box 4. The triangular box 4 can not only play the role of placing food but also observe the insects in the triangular box 4.

[0032] In order to screen out the already parasitized housefly pupae and Pachycrepoideus vindemmiae, a screening device 5 is installed on the device housing 1. The screening device 5 includes two groups of air blowing openings 51 formed on the device housing 1. A threaded cap 52 is threadedly connected to the air blowing opening 51. After the Pachycrepoideus vindemmiae in the device housing 1 are reared for 24 hours, rotate the threaded knob 32 to open the air blowing opening 51, blow air into the device housing 1 through the air blowing opening 51. After the Pachycrepoideus vindemmiae are blown into the triangular box 4 and lose their mobility, insert the box cover 41 to screen out the already parasitized housefly pupae and Pachycrepoideus vindemmiae.

[0033] It should be noted that in this text, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
