Description

Technical Field

[0001] This utility model belongs to the field of biological control technology for agricultural and forestry pests, and in particular relates to a device that helps to efficiently separate wasps from eggs when breeding egg parasitic wasps of the genera *Tetranychus*, *Tetranychus*, and *Tetranychus septemlobus* (especially single-egg, single-wasp) using intermediate host eggs (such as tussah silkworm eggs, castor silkworm eggs, and bean worm eggs). Background Technology

[0002] Using parasitic wasps to control pests is an important green pest control technology that aligns with the trend of ecological civilization construction and green development. Among these, egg parasitic wasps have received widespread attention, are the most extensively studied, and have the widest application, as they eliminate pests during their incubation period before they cause harm. For example, the egg parasitic wasp *Agiommatus* Huang can parasitize the eggs of lepidopteran moths such as silkworm moths, hawk moths, and skippers. Egg parasitic wasps of the genus *Anastatus* are widely distributed worldwide, and many species have been developed as natural enemy products. For instance, *A. fulloi* Sheng & Wang are used to control the litchi stink bug *Tessaratoma papillosa* (Drury), *A. japonicus* Ashmead is used to control the tea-winged stink bug *Halyomorpha halys* (Stål), and *A. orientalis* Yang & Choi are used to control the spotted lanternfly *Lycorma delicatula* (White). Parasitic wasps in the genus *Mesocomys* also have many applications in the field of biological control. For example, *M. albitarsis* (Ashmead) is used to control the pine caterpillar *Dendrolimus punctata* (Walker), and *M. trabalae* Yao, Yang & Zhao is used to control the ginkgo silkworm moth *Rinaca japonica* (Moore), achieving significant economic, ecological and social benefits.

[0003] A key aspect of achieving large-scale application of natural enemy insects is large-scale production. Unlike Trichogramma wasps, which are used only once in production, parasitic wasps such as the Scaled Egg Wasp, the Flat-bellied Wasp, and the Short-horned Flat-bellied Wasp have long lifespans and long egg-laying periods, requiring multiple replacements of host eggs during production. However, in the actual process of breeding using intermediate host eggs (such as tussah silkworm, castor silkworm, and bean worm eggs), parasitic wasps often remain on the surface of the host eggs after laying their own, making subsequent wasp-egg separation and management extremely complex. Currently, large-scale breeding still relies mainly on traditional separation methods (such as manual brushing or low-temperature treatment), which are not only time-consuming and labor-intensive but also prone to damaging the parasitic wasp queen, reducing breeding efficiency. Therefore, to optimize the breeding process of these parasitic wasps that require multiple replacements of host eggs during the queen wasp's use and are generally not sensitive to light attraction, a novel parasitic wasp-host egg separation device has been designed. This device aims to effectively separate parasitic wasps from host eggs, allowing the wasps to detach from the eggs after laying them, thus avoiding interference with subsequent breeding processes and improving breeding efficiency. The application of this technology can significantly improve the breeding efficiency and quality of parasitic wasps, which is crucial for promoting their application in the biological control of agricultural and forestry pests and fostering the high-quality development of green agriculture and forestry. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an integrated device for automatic separation and reproduction of parasitic wasps and host eggs. This device enables parasitic wasps to detach from host eggs after laying eggs, avoiding interference with subsequent breeding processes and thus improving breeding efficiency. Furthermore, it enhances the breeding efficiency and quality of parasitic wasps, promoting their application in biological control of agricultural and forestry pests and improving the high-quality development of green agriculture and forestry.

[0005] In view of this, the present invention provides an integrated device for automatic separation and reproduction of parasitic wasps and host eggs, including a protective box, a mounting platform, a box body, an upper plate, and a lower plate. The top of the box body has a through-hole for placing parasitic wasps and host eggs. The box body is movably mounted on the top of the upper plate. Nutrient holes are through-holes on both sides of the box body, allowing the placement of cotton balls soaked in honey water to supplement the parasitic wasps' nutrition. The interior of the upper plate has through-holes, and the lower plate is movably mounted on the bottom of the upper plate. A cylinder of a size corresponding to the holes in the upper plate is fixedly mounted on the top of each lower plate. The upper and lower plates combine to form a flat surface for placing host eggs. This device is designed for only one type of host egg and can adjust the size of the holes in the upper plate and the corresponding cylinder in the lower plate according to the size of the host eggs.

[0006] Based on the above structure, parasitic wasps and host eggs can be introduced through a bee-introducing hole at the top of the box. The host eggs are placed on the plane formed by the junction of the upper and lower plates. When using this device, only one type of host egg is needed; the size of the hole in the upper plate and the corresponding cylinder size of the lower plate can be adjusted according to the size of the host eggs. After the parasitic wasp encounters and parasitizes the host egg inside the box, the lower and upper plates are separated. The host egg exits through the hole at the bottom of the box, completing the wasp-egg separation process. The parasitized eggs are collected, achieving the goal of quickly and effectively separating the host egg and the parasitic wasp, thereby improving the efficiency of parasitized egg collection. Furthermore, the device has a nutrient hole inside for placing cotton balls soaked in honey water, which can supplement the parasitic wasps with nutrients during egg-laying, thereby improving the survival rate and reproductive capacity of the parasitic wasps.

[0007] Preferably, a protective box is movably installed on the outside of the box body. Protective side holes are provided through both sides of the protective box, and a protective top hole is provided through the top of the protective box. A mesh is fixedly installed inside the protective top hole.

[0008] Preferably, side plates are movably installed on both sides of the protective side hole, and side locking blocks are fixedly installed between the side plates. Rubber anti-slip sleeves are fixedly fitted on the outside of the side locking blocks.

[0009] Preferably, the side panels are all made of plastic, and handles are fixedly installed on both sides of the side panels.

[0010] Preferably, a mounting platform is movably mounted on the bottom of the lower plate, and a snap-fit ​​frame is fixedly mounted on the top of the mounting platform.

[0011] Preferably, a support base plate is fixedly installed at the bottom of the mounting platform, and a buffer base plate is fixedly installed at the bottom of the support base plate.

[0012] Preferably, the interior of the support base plate is fitted with mounting bolts, and the exterior of the mounting bolts is fitted with fastening nuts.

[0013] The beneficial effects of this utility model are:

[0014] 1. This integrated device for automatic separation and reproduction of parasitic wasps and host eggs introduces parasitic wasps and host eggs through a bee-inlet hole set through the top of the box. Then, cotton balls soaked in honey water are placed through the nutrient hole, which can supplement the parasitic wasps with nutrients when they lay eggs, thereby improving the survival rate and reproductive capacity of the parasitic wasps.

[0015] 2. This integrated device for automatic separation and reproduction of parasitic wasps and host eggs uses an upper and lower plate to form a flat surface for placing host eggs. It operates on a single type of host egg, and the size of the holes in the upper plate and the corresponding cylinder size of the lower plate can be adjusted according to the size of the host eggs. Once the parasitic wasp encounters and parasitizes the host egg within the box, the lower and upper plates are automatically separated, completing the wasp-egg separation process and collecting the parasitized eggs. This method can quickly and effectively separate host eggs and parasitic wasps, reducing manual operation time and damage to the mother wasp, thereby improving the efficiency of parasitized egg collection.

[0016] 3. Flexibility and adaptability: The design of this device can adapt to the production needs of different scales and is convenient for use in different breeding scenarios. It can be flexibly applied to both small-scale and large-scale breeding. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This application discloses an integrated device for automatic separation and reproduction of parasitic wasp-host eggs. Please refer to [link to relevant documentation]. Figures 1-5 The system includes a protective box 1, a mounting platform 3, a box body 6, an upper plate 7, and a lower plate 702. The system is characterized in that: the upper plate 7 has through holes 701 throughout; the lower plate 702 is movably mounted on the bottom of the upper plate 7; and cylinders 703, corresponding in size to the upper plate 7 and the holes 701, are fixedly mounted on the top of the lower plate 702. It is designed for use with only one type of host egg, and the size of the holes 701 and cylinders 703 can be adjusted according to the size of the host egg. The box body 6 is movably mounted on the top of the upper plate 7. Nutrient holes 601 are through-through on both sides of the box body 6, allowing the placement of cotton balls soaked in honey water to supplement the parasitic wasps' nutrition. A bee-placement hole 602 is through-through on the top of the box body 6.

[0026] Based on the above structure, parasitic wasps and host eggs are introduced through a bee-introducing hole 602 at the top of the box 6. The host eggs are placed on the plane formed by the junction of the upper plate 7 and the lower plate 702. Only one type of parasitic egg is used at a time, but the size of the hole 701 and the cylinder 703 can be adjusted according to the size of different types of host eggs. After the parasitic wasps encounter and parasitize the host eggs inside the box 6, they move to separate the lower plate 702 and the upper plate 7, completing the egg separation process and collecting the parasitized eggs. This method allows for quick and efficient separation of host eggs and parasitic wasps, reducing manual operation time and damage to the mother wasps, thereby improving the efficiency of parasitized egg collection. Furthermore, the device has a nutrient hole 601 inside for placing cotton balls soaked in honey water, which can supplement the parasitic wasps with nutrients during egg-laying, thereby improving their survival rate and reproductive capacity. The size of the hole 701 and cylinder 703 can be varied. For example, the diameter of hole 701 and cylinder 703 can be 3.2 mm when the host is a tussah silkworm egg, 1.8 mm when the host is a castor silkworm egg, and 2.0 mm when the host is a bean worm egg. The design of hole 701 and cylinder 703 must fully consider the average length of the host eggs (tussah silkworm eggs < 3.2 mm, castor silkworm eggs < 1.8 mm, bean worm eggs < 2.0 mm) and the body size of the female parasitic wasp (tussah silkworm egg reproduction > 3.5 mm, castor silkworm egg reproduction > 2.4 mm, bean worm egg reproduction > 2.6 mm). (mm), the design allows the host eggs to fall through the holes 701 while the parasitic wasps are kept inside the box 6. The second layer has circular protrusions 703 corresponding to the holes 701 of the first layer. When the two layers are combined, they form a smooth bottom so that the host eggs can be placed on the surface of the bottom first layer for the parasitic wasps to lay their eggs on.
