石梓叶甲(Craspedonta leayana insulana(Gressitt))在盈江县1a发生3代,以成虫在树皮缝隙、阴凉处或土中越冬,翌年5月初出来产卵,6月中旬第1代成虫出现,8月初第2代成虫出现,9月底第3代成虫出现,10月中下旬开始越冬。应用20%灭扫利乳油、2.5%联苯菊酯乳油、90%敌百虫晶体1000倍和2000倍液进行了室内和田间喷雾防治试验,3种药剂的1000倍与2000倍液对成虫和幼虫致死率没有显著的差异。
Craspedonta leayana insulana (Gressitt) occurred in Yingjiang County 1a for three generations. Adults landed in the bark crevice, shade or soil, and spawned in early May the following year.

The effects of 1000 times and 2000 times of three agents on adults and Mortality of larvae did not differ significantly.
