樟缀叶虫Cerace stipatana的初步研究

樟缀叶虫是樟树的一种重要害虫,该虫在福建一年发生4代,以蛹在叶苞中越冬,翌年3月上旬羽化。卵期3—4天,幼虫共5龄,幼虫期18～36天,蛹期8～16天,越冬蛹期148～166天。成虫寿命3～7天。每雌产卵量96～274粒。3～4月期间施放白僵菌粉炮以及喷洒80％敌敌畏、90％氰戊菊酯或90％敌百虫对该虫均有良好防治效果。

PRELIMINARY STUDY ON Cerace stipatana

Cerace stipatana Walker is an important insect pest of campher tree (Cinnamomum camphroa Nees. et Eberm. ) in Fujian Province. The pest has four generations each year and overwinters as pupa. Adult moths begin to appear in early March. The eggs stage lasts 3~4 days. Five instars are observed in the larval development which lasts 18~36 days. The overwin-tering pupal stage lasts 148~166 days and the others last 8~15 days. The adult moth lives for 3 ~7 days. Each female can lay 96~274 eggs. Control experiments showed that using Beauveria bassiana in March to April, spraying with 80% Dichlorvos 1000X ,20% Fenvalerate 4000Xand 90% Dipterxl000Xare very effective.
