潜叶蛾是柑桔夏秋季嫩梢上的主要害虫,尤其是在8月以后抽出的秋梢上为害更为剧烈。为害严重时叶片全部卷缩,嫩芽抽出0.5厘米潜叶蛾就开始产卵,直到新梢伸长到顶叶超过3厘米始止。在嫩梢上的侵害期达20天以上。以往防治潜叶蛾常用的磷胺和西维因药剂,近年来普遍发生抗性,药效显著下降。1980年我们在药剂筛选试验中,找到施用超微剂量的杀灭菊酯防治潜叶蛾有显著的效果。它的杀虫特点是:使用超微量10ppm浓度(即20％杀灭菊酯配水20000倍)能兼治幼虫和卵,击倒力强,不污染环境,持效期长,可减少喷药次数,降
Leaf moths are the major pests on the summer and autumn young shoots of citrus, especially when the autumn shoots are taken out after August. Serious damage when all the leaves curled, shoots out 0.5 cm leaf moth began to spawn, until the tip of the new tip to the top of the leaf more than 3 cm before the start. Infringement on the shoots up to 20 days or more. In the past, the commonly used phosphorus and amine hydrochloride for the control of leaf moths were generally resistant in recent years, and their efficacy was significantly reduced. In 1980 we in the drug screening test found that the application of supermicro doses of fenvalerate control of leaf miner has a significant effect. Its insecticidal characteristics are: the use of ultra-trace amount of 10ppm concentration (ie, 20% of 20% fenvalerate with water distribution) can control larvae and eggs, knockdown strong, does not pollute the environment, long duration, can reduce the number of spraying, drop
