Description

Technical Field

[0001] This utility model belongs to the field of fall armyworm larvae rearing, specifically relating to a single fall armyworm larvae rearing device. Background Technology

[0002] Currently, the rearing of fall armyworm larvae mostly adopts traditional artificial rearing methods. Due to the cannibalistic nature of larvae above the 3rd instar, larvae above the 3rd instar are mostly reared individually using petri dishes or finger tubes, or mixed in rearing boxes to control density. However, the following problems still exist: Although the rearing boxes can be reused, they take up a lot of space if large-scale rearing is carried out, and the rearing space inside is relatively fixed. When larvae die, it is difficult for users to quickly replace them. In addition, the integrated rearing method is not convenient for users to observe the larvae.

[0003] Therefore, to address the problem that the internal culture space of existing fall armyworm larvae rearing devices is relatively fixed and inconvenient for users to observe or feed the larvae, a single fall armyworm larvae rearing device has been developed. By adding a flexible and detachable culture structure and a double-opening lid structure to the fall armyworm larvae rearing device, it can be flexibly integrated. If a larva dies, it can be removed. If required by the project, the larvae can be selected from the whole board and integrated into a new board. It is low-cost, can be reused multiple times, and the matching box opening device can save a lot of time required for changing food in the middle. Utility Model Content
