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。
Through the study on the ecological characteristics of the leafroller, the relationship between its occurrence and environmental conditions (temperature and humidity) was found, and the prediction and forecast of the insect could be conducted accordingly. On the basis of prediction and forecasting, the drug control experiment was conducted on the leafroller. Proved 1400 times 50% dichlorvos + 800 times 40% omethoate best, should be the third generation in August egg hatch peak control, insecticidal rate of up to 95%.
