黑斑瘤蛾生物学特性及防治策略

Biological Characteristics and Control of Nola melanota Hampson

黑斑瘤蛾 N ola melanota Ham pson的寄主植物和生活史在国内外都未见报道 ,1995年首次在贵阳发现时危害紫薇十分严重 .为了探索该虫的发生规律和防治方法 ,在贵阳和长沙对其生物学特性进行了观察 .对黑斑瘤蛾卵、幼虫及蛹茧进行了描述 ,报道了该虫的年生活史、发生特点、危害习性等生物学特性 。

This paper is on the insect pest Nola melanota Hampson including its new host Lagerstroemia indica L., which was seriously harmed by the pest in Guiyang, Guizhou Province in 1995. In order to study its natural dynamics and the control method, surveys on the insect were taken in Guiyang (1997～1998) and in Changsha, Hunan Province (2000～2001). The description of its egg, larva, pupa, cocoon and the biological characteristics including yearly generations, population dynamics and habit is put forward, and the control measure of the pest is suggested according to the study.
