| 摘 要： | 利用果树害虫桃小食心虫、山楂叶螨、苹果黄蚜、梨木虱和金纹细蛾进行阿维菌素的毒力测定,按照阿维菌素对哺乳动物的急性经口毒性及对不同害虫的室内生物活性比值计算出药剂的安全指数,并分析阿维菌素适宜防治的害虫种类。通过分析认为,阿维菌素最适于防治山楂叶螨和梨木虱,其次为金纹细蛾、苹果黄蚜,不提倡使用阿维菌素防治桃小食心虫。通过横向分析比较,对于高效利用阿维菌素,减低药剂中毒风险和延缓抗药性有一定的作用。

| Abstract: | The efficacy ofabamectin was tested with peach fruit borer （Carposina sasakii Matsumura）, Hawthorn spider mite （Tetranychus vienensis Zaeher）, apple aphid （Aphis citricola van der Goot）, pear psylla （Psylla chinensis Yang et Li） and apple leaf miner （Lithocolletis ringoniella Matsumura）. The safety coefficient were calculated by LD50mammal/LD50pest （LC50pest）. According to the safety coefficient, the best target pests for abamectin are Hawthorn spider mite and pear psylla, and the abamectin is not suitable for controlling the Peach fruit borer. |
