摘要
为使防治竹织叶野螟工作达到最佳的生态效益和经济效益,对其防治指标进行研究。结果表明,损叶50％以下为轻度为害,损叶50～75％为中度为害,损害75％以上为严重为害;并根据害虫损叶量和毛竹产量损失的关系,提出了防治竹织叶野螟的指标。
The amount of defoliating and leaf-lossing caused by the bamboo leaf-roller, Algedonia coclesalis (Walker), simulation of artificial defoliating and the loss of Moso bamboo leftover raw material in current year, the Moso bamboo timber in following bumper year and the total yields of Moso bamboo shoot were studied at Gao Wuling village, Anji county, Zhejiang province durin 1988～1991. The results:showed that range of<50%, 50-70% and>75% of defoliating rate were light,middle and heavy.damage respectively. The control threshold of A. coclesalis was proposed based on the relationship between the amount of defoliating and the loss of Moso bamboo yield.
