摘　　要：本试验对柑桔粉虱进行了室内饲养和田间调查。结果表明:柑桔粉虱在四川一年发生4代,世代重叠,主要以大龄若虫和蛹在秋稍叶背越冬,其成虫和幼虫全年在四川有4个消长高峰期,其中4月中、下旬发生数量最多和危害最重,是控制柑桔粉虱的关键时期。In this experiment, Dialeurocles citri Ashmead were raised in laboratorial rearing and investigated in field. The result showed that it had 4 generations for a year in Sichuan area, and the generations overlapped, and the old larvae and pupae were on the leave back of autumn shoots through the winter. There were four adult peaks and the most serious harmfulness in middle to late April which was a key period for controlling Dialeurodes citri Ashmead.
