福建樗蚕生物学特性的观察

Observations about the Bionomics of Ailanthus Silkmoth Philosamia cynthia Walker et Feldor in Fujian Province

樗蚕是樟树的一种害虫。在福建一年发生二代,以蛹越冬,翌年4月中旬成虫开始羽化,卵产于叶上,幼虫6龄,少数5龄。黑瘤姬蜂、绒茧蜂、广大腿蜂和家蚕追寄蝇是其主要天敌。

The ailanthus silkmoth philosamia cynthia Walker et Feldor is a pest of camphor trees, Cinnamomum camphora Nees. et Eberm. It has two genera tions a year and overwinters as pupa in Fujian province. The overwintering pupae begin to emerge in mid-April next year. They lay their eggs on the leaf blade. The larvae generally have six instars, but a few of them only have five instars. Coccygomimus disparis Curtis, Apenteles sp, Brachymeria lasus(Walker) and Exorista sorbillas Wiedemann are major natural enemies of the ailanthus silkmoth.
