摘要
竹笋夜蛾主要为害淡竹、红竹、哺鸡竹和刚竹,据1988年在安吉县调查,其发生面积达6500亩,有虫株率10～80％,平均为45％。该虫以卵在禾本科、莎草科杂草上越冬,3月上旬幼虫孵化于杂草中取食,4月下旬蛀笋为害。竹林中杂草多少,决定该虫发生和危害程度,1988～1991年,进行了三次以竹林除草为主的防治试验。结果表明,利用百草枯水剂0.2 kg/亩或人工及时除草,防治效果都在90％以上。
The bamboo shoot moth, Oligia vulgaris (Bulter), is a main pest of the bamboos, such as Phyllostachys glauca, Ph. iridenscens, Ph. dutis and Ph. viridis in Zhejiang province. The area of bamboo forests damaged by it has been reachd to 6,500 mu and the rate of bamboos infested has been 10～80%, or average of 45% at Anji County, Zhejiang province in 1988. The pest overwintered as eggs on the grasses of Gramineae or Cyperaceae, its larvae hatched on early March, feeded on the grasses and subsequently bored into bamboo shoots on late April. Its occurence and damage degree was depended on abundance of the grasses in bamboo stands. The three-time trial of weeding against the pest was carried out respectively in bamboo stands during 1988～1991. The results indicated that control efficiency has been over 90% by weeding with paraquat of 0.2 kg/mu or artificial weeding.
