黄斑长翅卷叶蛾行为、习性的研究

黄斑长翅卷叶蛾 ,是我国北方果园重要害虫之一 ,在山西晋中为害尤其严重。本文对黄斑长翅卷叶蛾的取食、化蛹、羽化、求偶、交配、产卵、孵化等行为习性进行研究。结果表明 :黄斑长翅卷叶蛾幼虫分布在东南方位较西北多 ,第一代成虫雌雄性比 1 :1时为羽化高峰。一日内 ,8～ 1 0、1 8～ 2 0时两个羽化高峰 ,凌晨 4:30～ 5 :30为求偶、交尾高峰期。雌虫求偶行为发生与光照强度有关 ,约 1 0～ 5 0 0Lux时 ,求偶率最高。

Study on Behaviour and Habits of Yellow Tortrix (Lepidoptera:Tortricidae)

Yellow tortrix is one of the important pest in Chinese northern orchards, much serious in the middle part of Shanxi. Feeding, pupating, eclosion, calling, mating, oviposition and hatch of yellow tortrix were observed. The result showed that larvae are much in eastern and southern part than western and northern part of the tree. The first generation eclosion peak is that female to male is 1:1, and 8～10,18～20 o'clock are two peaks in a day. Calling and mating activity is at 4:30～5:30 in the morning. Female calling behavior relates to light. During 10～500 Lux, the calling rate is the highest.
