Abstract:The bionomics of Chilo suppressalis (Walker) had been studied by artificial raising in laboratory andinvestigation of fields from 1992 to 1995. The results showed that C suppressalis generally occurred two generationsecah year, but a few of individuals occurred only one generation. The life cycle and the meSt serious injury periodwere clarified at the same time. The mest serious injury period. of the first generation larvae was from the middle ofJune to the middle of July, and the second generation larvae from the middle of August to the harvest time. Severalliving habits of C suppressalis were also oberved.
Keywords:Chilo suppressalis (Walker)  bionomics
