摘要
研究发现嘉兴地区危害香樟树的丛螟科害虫为橄绿瘤丛螟Orthaga olivacea(Warren),对该虫的生物学特性和发生规律做了研究。该虫较为喜欢危害5~10年生香樟树,多头幼虫聚集在一起取食叶片,并缀合受害叶片成鸟巢状虫苞。在嘉兴地区1年发生2代。根据计算幼虫可分为7龄,符合Dyer生长规律。
An insect pest on the camphor trees in Jiaxing area of Zhejiang Province was identified as Orthaga olivacea (Warren) (Lepidoptera: Pyralidae) and its biological characteristics and occurrence were studied. The caterpillars of this species preferred to feed on camphor trees of 5 to 10 years old, and damaged tree leaves by aggregative feeding within nests formed by infested leaves.
