摘要
通过对杨黄卷叶螟生态学特性的研究，找出了其发生危害与环境条件（温、湿度）的关系，可依此进行该虫的预测预报。在预测预报的基础上对杨黄卷叶螟进行了药物防治试验。证明１４００倍５０％敌敌畏＋８００倍４０％氧化乐果液效果最好，宜在８月份第３代卵孵化高峰期进行防治，杀虫率可达９５％以上。
Ecological characteristics of Botyodes diniasalis Walker were studied in the paper
to find out the relationship between its ocurrence,harm and environmental wnditions,Which also
make forecast and prediction of the pest available.Medication control tests were also carried
out based on its forecast and prediction. The result showed that,1,400fold of 50%DDT+800fold
of 40% omethoate solution presented the best reults. The most suitable control season was Au
gust when the 3rd generation eggs are in fastigium for hatching. The killing rate could reach
more than 95%.
