| 摘 要： | 本研究了９种杀虫剂对小地老虎Ａｇｒｏｔｉｓ ｙｐｓｉｌｏｎ（Ｒｏｔｔｅｎｂｅｒｇ）３龄幼虫的触杀毒力。结果得出，触杀毒力从大到小的顺序：功夫菊酯、溴氰菊酯、农哈哈、卡死克、拉维因、米满、辛硫磷、锐劲特、敌百虫。其中功夫菊酯、溴氰菊酯和农哈哈的触杀毒力最强，比敌百虫高出１００００倍以上，在生产上可推荐使用。本试验还发现３龄幼虫的体重对毒力也有一定的影响。

| Abstract: | In this paper, toxicity of 9 insecticides for the third instar larvae of Agrotis ypsilon (Rottemberg) was tested. The results showed that the order from high to low of relative toxicities was arranged as follows: cyhalothrin, deltamethrin, bosswell, flufenoxuron, thiodicarb, mimic, phoxim, regent and trichlorphon. The toxicities of 2.5% cyhalothrin, 2.5% deltamethrin and 1% bosswell were much higher than others, their LD 50 were 10000 times more than 50% trichlorphon. As a result, the three insecticides were suggested to be used in chemical control. However, the weight of the third instar larvae affected toxicity too. |
