Description

Technical Field

[0001] This utility model relates to the field of extra-egg disinfection of lepidopteran insects, specifically to a tool for extra-egg disinfection of lepidopteran insects. Background Technology

[0002] Extra-egg disinfection of lepidopteran insects is an important means to improve egg hatching rates and reduce the chances of insect infection by pathogens. Maintaining high hatching rates and minimizing pathogen infection in lepidopteran insects within the laboratory is crucial for lepidopteran research. Lepidopteran insects are a globally distributed, omnivorous, herbivorous insect species with a wide host range. Some are major pests in forestry and agriculture, such as the fall webworm, gypsy moth, and poplar leafminer moth. Their hosts include poplar, willow, oak, and birch, causing significant economic losses in Eurasia and North America. Once lepidopteran larvae burst, they can defoliate host plants in a short period, leading to tree decline and subsequent pest and disease outbreaks. High hatching rates and healthy growth of lepidopteran insects in the laboratory facilitate subsequent research and experiments, enabling researchers to more quickly overcome the challenges of controlling lepidopteran pests.

[0003] Currently, lepidopteran insects commonly undergo extra-egg disinfection with 10% formaldehyde before hatching. However, due to the cilia covering the eggs and their small size, the eggs cannot be completely immersed in the formaldehyde solution, resulting in incomplete disinfection. After soaking in the formaldehyde solution, repeated rinsing with distilled water is necessary to completely remove the formaldehyde. Utility Model Content

[0004] This invention addresses the problem that, during the incubation of lepidopteran insect eggs, the eggs cannot be fully immersed in formaldehyde solution, resulting in incomplete disinfection. Therefore, it provides a tool for external disinfection of lepidopteran insect eggs.

[0005] The technical solution of this utility model is: Tools for exochemical control of lepidopteran insect eggs, including an egg mass storage box, a circular buckle plate, a box hanging plate, and a hanging rod assembly; The top center of the egg mass storage box is perpendicularly connected to one end of the hanging rod assembly, and the other end of the hanging rod assembly is perpendicularly connected to the center of the box body hanging plate. The circular buckle plate and the box hanging plate are used together. The circular buckle plate has a stepped hole at its center and is supported by the beaker below. The stepped holes of the circular buckle plate engage with the hanging plate of the box to seal the mouth of the beaker; When placing the egg storage box on the stepped hole of the circular buckle plate, the egg storage box is supported.

[0006] Furthermore, the boom assembly includes a boom with threads at both ends and a threaded sleeve; The lower end of the boom is detachably connected to the threaded sleeve via a threaded structure, and the threaded sleeve is integrally connected to the egg block storage box.

[0007] Furthermore, the egg mass storage box includes a cover, a mesh bag, and a buckle; The cover plate and the tail end of the net bag are rotatably connected, allowing the cover plate to be rotated off the net bag and opened. The cover and the top of the net bag are fastened together by buckles, and the cover closes the opening of the net bag.

[0008] Furthermore, the cover, net, and buckle are made of stainless steel, with the net having a funnel-shaped mesh structure and the cover having a circular structure.

[0009] Furthermore, the outer edge of the cover plate is an annular iron plate structure, the center position is a circular plate structure, and the rest is a metal mesh structure. The annular iron plate structure is integrally connected to the circular plate structure through the metal mesh structure. The circular plate structure at the center of the cover plate is fixedly connected to the threaded sleeve. Furthermore, the top annular surface of the net is a ring-shaped iron plate structure, while the rest is a metal mesh structure, and the ring-shaped iron plate and the metal mesh structure are integrally connected.

[0010] Furthermore, the beaker has a body diameter of 52mm and a height of 72mm.

[0011] Furthermore, the buckle is a metal elastic buckle.

[0012] Compared with the prior art, the present invention has the following advantages: This utility model's egg storage box adopts a funnel-shaped mesh structure, which can increase the contact area between formaldehyde solution and lepidopteran insect eggs (including external cilia). At the same time, the hanging rod assembly and box body hanging plate prevent the egg storage box from floating, ensuring that the egg blocks are completely submerged in the disinfectant solution, thus solving the problem of incomplete disinfection in existing methods.

[0013] After disinfection, the egg mass storage box can be directly placed on the stepped holes of the circular buckle plate for rinsing. The waste liquid flows into the beaker in a concentrated manner, eliminating the need for additional transfer of egg masses, simplifying the rinsing operation and improving experimental efficiency.

[0014] This utility model uses a circular buckle plate and a box hanging plate to form a sealed structure, which can effectively block the volatilization of formaldehyde gas, avoid harming the health of laboratory personnel, and improve operational safety. Attached Figure Description

The circular buckle plate 2 and the box hanging plate 3 are used together. The circular buckle plate 2 has a stepped hole 5 at its center and is supported by the beaker 6 below. The stepped hole 5 of the circular buckle plate 2 is fastened to the box body hanging plate 3 to seal the mouth of the beaker 6; When the egg storage box 1 is placed on the stepped hole 5 of the circular buckle plate 2, the egg storage box 1 is supported.

[0018] The circular buckle plate 2 and the box hanging plate 3 are used together in a matching manner. A stepped hole 5 is opened through the center of the circular buckle plate 2, and the edge of the circular buckle plate 2 rests on the mouth of the beaker 6. When disinfection is carried out, the stepped hole 5 of the circular buckle plate 2 is tightly fastened to the box hanging plate 3, sealing the mouth of the beaker 6 and preventing the volatilization of formaldehyde gas. When cleaning, the egg storage box 1 can be placed directly in the stepped hole 5 of the circular buckle plate 2. The stepped surface of the stepped hole 5 provides stable support for the egg storage box 1, which facilitates the rinsing operation.

[0019] This implementation method provides a basic framework for subsequent disinfection and cleaning operations, ensuring that all components work together and balancing disinfection effectiveness with operational safety.

[0021] The lower end of the boom 41 is detachably connected to the internal thread of the threaded sleeve 42 via an external thread structure, which facilitates the installation and disassembly of the boom 41 and the threaded sleeve 42. Specific implementation method three: Combination Figure 1 — Figure 7 This embodiment describes a tool for exotoxic disinfecting of lepidopteran insect eggs, wherein the egg storage box 1 includes a cover plate 11, a net bag 12, and a buckle 13; The cover plate 11 and the net bag 12 are rotatably connected at their tail ends, so that the cover plate 11 can be rotated open from the net bag 12; The cover plate 11 and the head of the net bag 12 are fastened together by the buckle 13, and the opening of the net bag 12 is closed by the cover plate 11.

[0023] The cover plate 11 and the net bag 12 are rotatably connected. The tail of the cover plate 11 has a post, and the tail of the net bag 12 is symmetrically provided with two posts. The post at the tail of the cover plate 11 is inserted between the two posts at the tail of the net bag 12 and rotates through a shaft.

[0024] A cylindrical insert is welded to the tail of the cover plate 11, and two cylindrical inserts are symmetrically welded to the tail of the net bag 12. The insert at the tail of the cover plate 11 is inserted between the two inserts at the tail of the net bag 12, and a shaft passes through the three inserts to realize the rotational connection between the cover plate 11 and the net bag 12, so that the cover plate 11 can rotate flexibly around the shaft, thereby opening or closing the cover plate 11 from the net bag 12. The top ends of the cover plate 11 and the net bag 12 are fastened together by the buckle 13. When the cover plate 11 is closed, the opening of the net bag 12 can be closed by the cover plate 11 to prevent the lepidopteran insect egg masses placed in the net bag 12 from falling out. When it is necessary to place or remove the egg masses, the buckle 13 can be released and the cover plate 11 can be rotated. The operation is convenient, which not only ensures the stability of the egg masses storage, but also simplifies the operation of placing and removing the egg masses, and is suitable for the needs of batch disinfection in the laboratory.

The cover plate 11, net bag 12, and buckle 13 are made of stainless steel. The net bag 12 has a funnel-shaped mesh structure, and the cover plate 11 has a circular structure.

[0026] The cover plate 11, net bag 12 and buckle 13 are all made of stainless steel. The net bag 12 has a funnel-shaped mesh structure, which can increase the contact area between the formaldehyde solution and the egg mass, allowing the disinfectant to fully wrap the egg mass (including the external cilia), improving the thoroughness of disinfection. At the same time, it facilitates the flow of distilled water during rinsing, quickly removing residual formaldehyde, which meets the special needs of external disinfection of lepidopteran insect eggs. Specific implementation method five: Combination Figure 1 — Figure 7 This embodiment describes a tool for exfoliating lepidopteran insect eggs. The outer edge of the cover plate 11 is an annular iron plate structure, the center is a circular plate structure, and the rest is a metal mesh structure. The annular iron plate structure is integrally connected to the circular plate structure through the metal mesh structure. The circular plate structure at the center of the cover plate 11 is fixedly connected to the threaded sleeve 42. The outer edge of the cover plate 11 is an annular iron plate structure (thickness not less than 1mm) to enhance the edge strength of the cover plate 11 and provide a fastening support point for the buckle 13; The center of the cover plate 11 is a circular iron plate structure, which is used to fix it to the threaded sleeve 42. Except for the outer edge annular iron plate and the central circular iron plate, the rest of the cover plate 11 is a metal mesh structure. The metal mesh structure is integrally formed and connected with the outer edge annular iron plate and the central circular iron plate to ensure the integrity of the structure. Specific implementation method six: Combination Figure 1 and- Figure 7 This embodiment describes a tool for exfoliating lepidopteran insect eggs. The top annular surface of the net 12 is a ring-shaped iron plate structure, while the rest is a metal mesh structure. The ring-shaped iron plate and the metal mesh structure are integrally connected to ensure a sturdy structure that is not easily deformed. The metal mesh structure of the net bag 12 has a mesh density of <0.3mm. This density design ensures that lepidopteran insect egg masses cannot fall through the mesh, while allowing 10% formaldehyde solution and distilled water to penetrate smoothly, achieving thorough disinfection and rinsing of the egg masses.

[0029] It further improves the stability of egg mass storage and the thoroughness of disinfection and cleaning, and is suitable for the characteristics of lepidopteran insect eggs, which are small in size and have cilia on the outside.
