The results showed that when the larvae were fed with Bt from one to seven days, a series of change happened to different parts of the midgut. The cell membrane of the midgut cells dissolved on the first day, and disappeared on the seventh day. Other symptoms observed included： the karyotheca dissolved, the nucleolus and the endoplasmic reticulum disappeared. Through a series of changes in the midgut cells, the larvae finally died.
