摘要
本文研究了 9种杀虫剂对小地老虎 Agrotisypsilon(Rottemberg) 3龄幼虫的触杀毒力。结果得出 ,触杀毒力从大到小的顺序为 :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 10 0 0 0倍以上 ,在生产上可推荐使用。本试验还发现
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.
