The design was then divided into two groups based on addition or without addition of vegetable leaves to study the effects of compound feed and vegetable leaves on growth and de- velopment of T. molitor. The results showed that body weight, duration, crude protein content and pupation rate of larvae and emergence rate of adults were significantly affected by compound feed and vegetable leaves （ P 〈 0.05）. The larvae bred with feed 5 had the largest body weight, with the shortest duration; the larvae bred with feed 3 had the highest pupation rate; the larvae bred with feed 7 had the highest crude protein content; the adult bred with feed 9 had the largest emergence rate. Overall breeding effect of feed 7 ＋ vegetable leaves was better than any other groups, with ideal indicators, higher utilization rate and lower breeding cost. Its formula was w （wheat bran） = 33.33%, w （corn） = 33.33%, w （corn stalks） = 33.33%. Therefore, the growth of T. molitorwas significantly affected by feed types, and feed 7 ＋ vegetable leaves could be promoted in the production.展开更多

In addition, a two-time coating method is used to improve the numerical apertures of the compound lenses.
