Description

Technical Field

[0001] This utility model relates to the field of insect breeding technology, specifically to a device for efficiently and quickly carrying out mating and egg collection of lepidopteran insects. Background Technology

[0002] Lepidoptera is one of the most diverse groups of insects, with approximately 180,000 known species, mainly including butterflies and moths. These insects play a vital role in ecosystems, serving as crucial mediators of plant pollination networks and also as major pests in agricultural and forestry production. Due to their complex metamorphic development processes—from egg to larva to pupa to adult—research on the control of lepidopteran pests requires a systematic understanding of their biological characteristics, ecological patterns, and pesticide resistance mechanisms. This research relies on standardized population breeding systems under laboratory conditions. Effective adult mating and oviposition techniques are key steps in achieving population expansion.

[0003] The commonly used method is to collect the pupae of lepidopteran insects together, identify the male and female adults after they emerge, and then transfer them individually for mating. However, if the transfer is not handled properly, the antennae or other tissues of the adults can be accidentally damaged, thus affecting their mating behavior or ability to find a host. Furthermore, this method is inefficient. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a highly efficient and rapid device for the mating and egg collection of Lepidoptera insects, which can effectively improve experimental efficiency and the quality of adult insect breeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for efficient and rapid collection of mating and egg-laying of lepidopteran insects, comprising a collection cup, the top of which is provided with a detachable mesh cover, the bottom of which is covered with a moisture-retaining paper, a water injection hole on the periphery of the collection cup, two feeding ports symmetrically arranged on the periphery of the collection cup and arranged above the water injection hole, and two slots symmetrically arranged on the periphery of the collection cup in a direction perpendicular to the axis of the feeding ports, through which the egg-laying cloth is inserted into the inside of the collection cup.

[0006] Preferably, the feeding port is threadedly connected to the feeding cover, cotton is placed inside the feeding port, and a water inlet is opened at the closed end of the feeding cover.

[0007] Preferably, the mesh cover has a mesh opening at its center, the mesh is bonded to the mesh cover and covers the mesh opening, and the mesh is a 50-mesh mesh.

[0008] Preferably, the upper edge of the collecting cup is provided with an outwardly turned cup rim, and the inner side wall of the mesh cover is provided with an inwardly protruding elastic locking ring, which is locked and fixed to the cup rim.

[0009] Preferably, the egg-laying cloth is a coarse yarn steamer cloth.

[0010] Compared with existing technologies, the advantages of this invention are as follows: By placing a certain proportion of male and female pupae into a collection cup, and using moisturizing paper at the bottom to replenish moisture and promote eclosion, the moisturizing paper is removed promptly after eclosion. The egg-laying cloth is then inserted into the collection cup through a slot on its periphery. This slot secures the egg-laying cloth, preventing it from collapsing and affecting the egg-laying process. Adult insects receive nutrition through their feeding openings. After mating and egg-laying, the egg-laying cloth is removed after the adults die, and the insects are placed in a suitable environment for incubation. The entire process eliminates the need to transfer the adults, preventing accidental damage to their antennae or other tissues, thus avoiding interference with mating or host-seeking behaviors. Furthermore, the operation is simple and effectively improves experimental efficiency. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0017] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0018] Example 1

[0019] like Figures 1 to 3As shown, this utility model provides a device for efficient and rapid collection of mating and egg-laying of lepidopteran insects, including a collection cup 1. The top of the collection cup 1 is provided with a detachable mesh cover 2, and the bottom is covered with a moisture-retaining paper 3. A water injection hole 101 is opened around the collection cup 1. Two feeding ports 102 are also symmetrically arranged around the collection cup and arranged above the water injection hole 101. Two slots 103 are symmetrically arranged around the collection cup 1 in the direction perpendicular to the axis of the feeding ports 102. An egg-laying cloth 4 is inserted into the collection cup 1 through the slots 103.

[0020] A specific ratio of male and female pupae is placed in a collection cup 1. Moisturizing paper 2 (placed at the bottom) provides moisture to the pupae, promoting eclosion. After eclosion, the moisturizing paper 2 is removed, and an oviposition cloth 4 is inserted into the collection cup 1 through a slot 103 around its perimeter. The slot 103 secures the oviposition cloth 4, preventing it from collapsing and affecting the oviposition process. Adult insects receive nutrition through the feeding opening 102. After mating and oviposition, the oviposition cloth 4 is removed after the adults die, and the insects are placed in a suitable environment for incubation. The entire process eliminates the need to transfer the adults, preventing accidental injury to their antennae or other tissues, thus avoiding interference with mating or host-seeking behaviors. Furthermore, the operation is simple and effectively improves experimental efficiency. In this embodiment, the beet armyworm was used as the experimental subject. The method for identifying the sex of the pupal stage was as follows: the junction of the 7th and 8th abdominal segments of the male pupa was smooth, and there was a longitudinal crack in the center of the ventral surface of the 9th abdominal segment, which connected two semi-circular tubercle-like protrusions. This crack was the male genital opening on the 9th abdominal segment; the junction of the 7th and 8th abdominal segments of the female pupa was not smooth, and there was a protruding structure close to the center of the 8th abdominal segment, which was the female genital opening and oviposition opening on the 8th abdominal segment.

[0021] Furthermore, the feeding port 102 is threadedly connected to the feeding cover 5, and cotton 6 is placed inside the feeding port 102. A water inlet 501 is provided at the closed end of the feeding cover 5. The feeding port is sealed by the feeding cover 5 to prevent external dust from entering the feeding port 102 and contaminating the nutrient solution. The cotton 6 is placed to absorb the nutrient solution, thus avoiding waste. The water inlet at the closed end of the feeding cover 5 is used to replenish the nutrient solution to the cotton 6. When the cotton 6 becomes yellow or smelly, it can be removed and replaced by rotating the feeding cover 5.

[0022] Furthermore, a mesh opening 201 is provided in the center of the mesh cover 2, and a mesh 7 is bonded to the mesh cover 2 and covers the mesh opening 201. The mesh 7 is a 50-mesh mesh. To prevent adult insects from escaping while also ensuring breathability, a mesh opening 201 is provided in the center of the mesh cover 2, and the rest is sealed. The mesh 7 is fixed by adhesive, making it easy to disassemble and replace.

[0023] Furthermore, the upper edge of the collecting cup 1 is provided with an outwardly turned cup rim 104, and the inner wall of the mesh cover 2 is provided with an inwardly protruding elastic locking ring 202. The cup rim 104 is locked and fixed to the elastic locking ring 202. The mesh cover 2 is locked under the cup rim 104 by the deformation of the inwardly protruding elastic locking ring 202, and is locked by the rebound force. It can be installed and removed by pressing with one hand, which is suitable for frequent opening and closing scenarios.

[0024] Furthermore, the egg-laying cloth 4 is a coarse yarn steamer cloth. The coarse yarn steamer cloth is of rough material, and female insects prefer to lay eggs on the cloth, which increases the number of eggs laid by female insects.

[0025] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
