摘　　要：麻楝蛀斑螟在云南石岩寨地区１年发生４代，以蛹越冬．该虫以幼虫钻蛀珍贵速生树种红椿树主梢和侧梢，造成枝条中空、断折，从而形成多头树而难以成材．云南省红椿主产区的林分，６０％～１００％的植株受其危害，且幼林受害尤重．生产实践证明，螟害是造成省内红椿造林多年未获成功的主要因素．该文就麻楝蛀斑螟的分布、危害、生物学特性、发生规律和有效防治方法进行了较深入的探讨。The life of the pest. Hypsipyla robusta has 4 generations in a year in Shiyanzhai area,Yunnan Province.It overwinters as pupa. The larva bores the branches of toon, a kind of valuable tree which grows fast. In the above area,60%～100% of the trees has been injured, at the thicket stage. It has been proved by practice that some kinds of pyralid moths have played a significant role in the longterm failure of silviculture of toon in Yunnan Province. The regularity of distribution,injury,occurrence, the biology and control of this pest have been introduced in this paper. The control of this pest,should be based on silvicultural management,pest forecast and survey. It includes manual control in winter and spring, proper chemical control in summer and autumn,biological control of the population. 
