Description

Technical Field

[0001] This utility model relates to the field of insect breeding technology, specifically to a breeding device for American serpentine leafminer. Background Technology

[0002] The American serpentine leafminer (S. cerana) feeds on animals of the genus *S. cerana* in the family Lepidoptera. Other names include vegetable leafminer, snake-shaped leafminer, and cabbage leafminer. Morphologically, the adult American serpentine leafminer is 1.3-2.3 mm long, light grayish-black, with a glossy black thorax and a yellow ventral surface. Females are larger than males. The larvae are maggot-like, initially colorless, later turning light orange-yellow to orange-yellow, reaching 3 mm in length. The posterior spiracles are conical projections with three forks at the apex, each with an opening.

[0003] The American serpentine leafminer is a typical polyphagous pest, with over 100 known plant species as hosts, primarily cucurbitaceous and leguminous crops. The larvae burrow into leaves and petioles, creating irregular, serpentine white tunnels. This damage destroys chlorophyll, impairing photosynthesis; severely affected leaves wither and fall off; flower buds and fruits are scorched; and in severe cases, seedlings are destroyed. Therefore, research into the life cycle and reproductive characteristics of the American serpentine leafminer is crucial for effectively preventing its infestations in agricultural production.

[0004] However, in the experimental research of leafminer flies, the current method of breeding leafminer flies in conventional containers is not feasible. Firstly, it is not easy to simulate the wild living environment of adult leafminer flies. Secondly, when adding food and collecting pupae, the adults are prone to flying out of the container, which makes the collection of pupae and the transfer of adults difficult, thus bringing certain challenges to the indoor breeding of leafminer flies. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a breeding device for American serpentine leafminer, which ensures good air permeability, provides a good living environment for adult leafminers, and effectively prevents adults from flying out when adding food and collecting pupae, making it easy to collect pupae and transfer adults, thus realizing indoor breeding of leafminers.

[0006] This utility model provides a rearing device for American serpentine leafminer, including an insect cage structure. A feeding structure is detachably mounted on the top of the insect cage structure, and a pupa collection structure is detachably mounted on the bottom of the cage structure. Wherein:

[0007] The insect cage structure includes a cylindrical cage frame with an opening at the top and a mesh screen at the bottom, forming a slot between the lower side of the mesh screen and the bottom of the cage frame.

[0008] The feeding structure includes a top frame, which is detachably mounted on the top of the cage frame. A feeding port is provided in the middle of the top frame. Several feed trough connecting rods are vertically arranged below the feeding port. The lower end of the feed trough connecting rods is connected to the feeding trough. A top cover is detachably mounted on the feeding port.

[0009] The pupa collection structure includes a pupa receiving tray, which can be detachably placed inside the slot.

[0010] Preferably, the lower part of the cage frame is provided with an outer support ring and an inner support ring, and the outer support ring and the inner support ring are connected by several support rods, with the mesh disposed on the upper side of the support rods and the inner support ring.

[0011] Preferably, the cage frame includes a base plate, several vertical rods are vertically arranged on the base plate, a cage frame top ring is provided at the top of the vertical rods, and a cage frame nylon net is laid on the vertical rods.

[0012] Preferably, the top frame includes an outer ring and an inner ring, the outer ring and the inner ring are connected by several top frame connecting rods, and a top frame nylon net is laid between them. The inner ring is a feeding port.

[0013] Preferably, the cage has an outlet on one side, a connecting collar is provided on the outlet, and a side cover is detachably provided on the connecting collar.

[0014] Preferably, the connecting collar is fitted with an adult insect transfer structure, which includes an outlet support, an outlet nylon net is laid on the outlet support, and two vertically detachable insert plates are installed on the outlet support, with a card plate on the upper side of the insert plates.

[0015] Preferably, the cage frame contains a breeding structure, which includes a hydroponic chamber filled with water and nutrient solution, and a planter is detachably mounted on its upper part.

[0016] Preferably, the pupal receiving tray is provided with several baffles, which divide the interior of the pupal receiving tray into several pupal receiving slots, and the outer wall of the pupal receiving tray is provided with handles.

[0017] Preferably, the top cover is provided with a handle on its upper side.

[0018] Preferably, an escape-proof net is provided on the feeding trough connecting rod, and the edge of the feeding trough is inclined outwards.

[0019] The working principle of this invention is as follows: This American serpentine leafminer rearing device utilizes a cage frame as a supporting structure. A nylon mesh is laid around the vertical rods to provide living space for the leafminers, preventing them from flying out of the cage and ensuring good ventilation. Secondly, the device features a feeding structure at the top of the cage structure. Food can be added to the feeding trough by opening the top cover, facilitating feeding and preventing the leafminers from flying out during feeding. In addition, a strainer and a pupal collection structure are installed at the bottom of the insect cage structure. The pupal collection tray is placed in the slot below the strainer in the form of a drawer. After the leafminer lays its pupae, the pupae fall into the pupal collection tray through the holes in the strainer. To ensure that the pupae fall into the pupal collection tray smoothly, the strainer can be set to be inclined, so that the pupae can fall through the holes more easily when rolling. When collection is needed, the pupal collection tray can be pulled out to collect the pupae, which is convenient for removing the pupae. The pupal collection tray is divided into several small squares of equal area by a partition. By observing which direction the leafminer pupae fall, it can help to analyze the influence of environmental factors on the leafminer's pupal laying habits. Additionally, the device includes an adult transfer structure on one side of the insect cage structure. A set of insert plates is installed on the outlet support, with locking plates on the upper side of the insert plates to overlap and support the upper side of the outlet support. When it is necessary to remove adult leafminers, the adult transfer structure is fitted onto the connecting collar. First, the insert plate on the side closer to the insect cage structure is opened. Once the leafminer flies into the space between the two insert plates, the insert plate is closed. The opening of another container is then aligned with the outlet of the adult transfer structure, and the insert plate on the side closer to the outlet is opened, transferring the leafminer from the insect cage structure into another container. Furthermore, a breeding structure can be placed inside the insect cage structure, consisting of a hydroponic chamber and a planter. By using hydroponics to cultivate green plants, a more suitable environment for the host plant is provided.

[0020] The beneficial effects of this utility model are as follows: The American serpentine leafminer breeding device of this utility model can ensure good air permeability, provide a good living environment for adult leafminers, and effectively prevent adults from flying out when adding food and collecting pupae. It facilitates the collection of pupae and the transfer of adults, and can realize the breeding of leafminers indoors. Moreover, the device has a simple structure and is easy to operate.
