摘要
竹织叶野螟(Alged012ia GOClesalis Walker)是我省毛竹的重要害虫。作者于1989—1990年对该幼虫食叶量及当年新竹叶面积作了研究测定,幼虫期平均食叶量为101.490±4.1157 cm^2,各径级毛竹平均叶面积为192139.5302±23621.4434 cm^2。本文提出了不同径级毛竹的各为害程度相对应的虫口数量。
Algedonia coclesalis Walker is an important injurious insect of Phyllostachys pubescens in zhejiang. We researched the amount of leaves eaten by its larva and determined the leaf areas of young bamboo in those years-1980～1990. The average amount of leaves eaten by Algedonia coclesalis Walker and the average leaf area in various diameter classes of bamboo measured respectively 101.490±4.1157 cm^2 and 192139.5302±23621.4434cm^2. The larva amount of various harm degrees for different diameter classes bamboo were preliminary demonstrated.
