摘要
杨桃鸟羽蛾(Diacrotricha fasciola Zeller)属鳞翅目(Lepidopter)羽蛾科(Pterophoridae),以幼虫取食嫩梢叶片造成叶片孔洞或缺刻、或在花期同时蛀食为害花蕾造成落花和花穗枯死,对杨桃生产造成严重影响。本文通过田间调查和室内饲养观察,阐述了鸟羽蛾的形态特征、生物学特性;通过系统调查,探明了杨桃鸟羽蛾的为害率和自然种群动态。
Diacrotricha fasciola Zeller belongs to Pterophoridae in Lepidopter.It＇s larvae feed on both the young sprout leaves and flower buds,caused to falling or dying of the flower and to the production of Averrhoa carambola L.reduced.The morphological and biological characteristics of D.fasciola were reported by field investigation and laboratory observation,and the damage rate in field and natural population dynamics of D.fasciola were verified by systematical investigation in this paper.
