摘要
刚竹毒蛾Pantana phyllostachysae Chao防治指标研究结果表明:损叶50％以下为轻度为害,损叶51—75%为中度为害,损叶75%以上为严重为害,并根据害虫损叶量和毛竹产最损失的关系,提出了刚竹毒蛾的防治指标。
The results of studies on control threshold showed that ranges of <50%, 51 ?75% and >75% of defoliating rate were light, middle and heavy damage, respectively, The control threshold of Pantana phyllostachysae Chao was based on the relationship between the amount of defoliating and the loss of Moso bamboo yield.
