| 摘 要： | １９９２～１９９５年，通过室内外人工饲养及田间调查研究，明确了二化螟在辽宁省每年发生两代，但少数个体仅发生１代；同时明确了二化螟的生活史与害虫的为害盛期，第１代幼虫为害盛期为６月中旬至７月中旬，第２代幼虫为害盛期为８月中旬至收获期；观察了二化螟的若干生活习性。

| 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. |
