摘要
阿维菌素是一种新型的生物杀虫制剂。本试验筛选出了利用阿维菌素防治美国白蛾的最佳体积浓度，即1～3龄为1：12000，4～5龄为1：8000，最佳体积浓度下第5天的杀虫效果为97．7％，其杀虫效果优于苏芸金杆菌，而成本却低于苏芸金杆菌。
Avermectin is a new biological pesticide. Screening test for best concentration to control Hyphantria cunea by Avermectin was conducted, following results were obtained： 1 ： 12 000 for 1 - 3 instars and 1 ： 8 000 for 4 - 5 instars are the optimum concentration,respectively; insecticidal effect has attained 97.7% in fifth day after use which exceeded Bacillus thuringiensis, but the cost is lower than Bacillus thuringiensis.
