Description

A large-scale breeding equipment and feeding tray for mosquito larvae

technical field

The invention relates to the technical field of equipment for raising and cultivating sterile males, in particular to a large-scale breeding equipment and a feeding tray for mosquito larvae.

Background technique

In pest control, sterile male insect release technology is an emerging technology, that is, to cultivate sterile male insects and release them, so that the male and female insects cannot reproduce after mating, so as to achieve the purpose of eliminating the insects. Mosquitoes can carry viruses and germs in the blood of animals and spread diseases, so how to use sterile male release technology to eliminate mosquitoes has become a research topic.

The life cycle of mosquitoes can be divided into four stages, namely eggs, larvae, pupae, and adults. The larvae are called larvae. The larvae breathe through straws and feed on organic matter and microorganisms. The bristles in the mouth produce water flow and flow to the mouth. This period lasts about 5 to 10 days, and becomes a pupa after molting 4 times.

In a large-scale male mosquito release program, large-scale breeding of male mosquitoes is required, and one of the key links is the large-scale rearing of mosquito larvae.
