摘要
对云杉小卷蛾的形态特征、生物学特性、生态学习性进行了观察，并对其防治技术进行了研究。该虫在青海为害云杉。一年１代，以幼虫取食芽基、嫩茎，并钻蛀顶芽。以蛹在云杉冬芽内越冬，４月中旬成虫羽化、产卵，５月上旬幼虫出现，６～７月中旬化蛹。在产卵初期根施呋喃丹，幼虫初期喷洒氧化乐果、氯氰菊酯可获较好防效。在成虫羽化初期喷敌敌畏、氧化乐果、高效氯氰菊酯，每隔７～１０天１次，共喷３次，可杀死未产卵的成虫。
The morphological characters,bionomics,ecological habits and control technology of Neobarbara olivacea are studied.N. olivacea injures Picea crassifolia in Qinghai.It occures one generation a year,the larva eats basal buds,tender stems and bores terminal buds.It overwinters as pupa in winter buds of P. crassifolia,the adult emerges and lays eggs in the middle ten days of April,the larva appears in the first tenday of May and becomes pupa in June～the middle ten days of July. Its effective for control to apply Furadan 3 G on to the roots of the trees in early days of oviposition and to spray Dichlorvos,Omethoate and Cypermethrin on to the young larvae and adults.
