At present, research has been carried on about resources of green lacewing and its biology, ecology, ethology of common species, and reproductive technology on a large scale, natural feed and artificial feed as well. However, research on reproductive physiology respect of green lacewing now is less and hasn"t gone too far. This article has carried on certain studies on this respect, aiming at offering theoretical direction for giving play to green lacewing"s reproductive latent, raising artificial reproductive efficiency and field effective protection and utilization.
