摘要
选用２０％氰戊菊脂、９０％敌百虫、８０％敌敌畏等三种农药的不同浓度，对茶袋蛾、黑荆大造桥虫，柑桔长卷蛾等黑荆树主要害虫，以正交拉丁方设计进行林间防治试验．结果分析表明，浓度对防治效果有显著影响，以２０％氰戊菊脂２０００倍液、９０％敌百虫８００倍液、８０％敌敌畏８００倍液效果最佳．不同害虫种类对药剂有一定选择性．利用超轻型飞机喷洒２０％氰戊菊脂１００倍液或白僵菌效果较好．
The results of experimental control of the larvae of Ciania minuscula Butler,Ascotis selenaria cretacea Butter and Homona coffearin Megrick,have shown that spraying with 20% Femalerate 2000x,90% Dpeera 800x and 80% bichlorlos 800x pr ove to be most effectics,that different concentrations result in different mortality,that it is therefore necessary to select different kinds of insecticides for various pests,and that the use of a super light plane (A-IB) for distributing the emulsion oil water solvent (1: 100) containing 20% Fenvalerate and Beauveria bossiana proves very effective and promising as well.
