摘要
通过室内饲养和林间调查,研究刺股沟臀肖叶甲在油茶林发生的生物学特性。结果表明:该虫在福建1 a发生1代,成虫取食油茶叶片,幼虫在土壤中生活。翌年4月中旬越冬幼虫化蛹,4月下旬成虫始见,高峰期在5月中旬—6月中旬;每雌成虫可产卵35～100粒。垦复措施可降低油茶林的受害率。
Through rearing in lab and survey in the field ,the biological characters of Colaspoides opaca in C.oleifera forest were stud-ied.The results showed that C.opaca occurred for 1 generation one year.The adults feed on leaves of C.oleifera,and the larvae feed in land.It overwintered in soil as larvae.Pupation occurred in last 10 days of April.The peak period of adults was from mid-May to mid-June;Every female adult laid 35~100 eggs.The insect made less damage on C.oleifera forest.
