本文通过十种化学杀虫剂对德国小蠊成虫的胃毒及接触毒性测定试验，观察不同杀虫剂在常用浓度下对蜚蠊的主要毒杀作用方式。结果表明白蚁灵、硅白灵、敌敌畏、敌百虫、残杀威、毒死蜱对试虫的经口毒性及接触毒性均较明显，乙酰甲胺磷与灭蚊灵对试虫有经口毒性大于接触毒性的趋势，硼酸对试虫具经口毒性与接触毒性，而双氧威在短期内对试虫的毒效不明显。 In this paper, ten kinds of chemical insecticides on German cockroach adult stomach poisoning and contact toxicity test to observe the different insecticides at the usual concentrations of cockroaches in the main poisoning mode. The results showed that the oral toxicity and the contact toxicity of termitic acid, silibinin, dichlorvos, trichlorfon, propoxur and chlorpyrifos were all significantly higher than those of the control group Toxicity trend, boric acid on the test insect with oral toxicity and contact toxicity, and the toxicity of hexamethonium in the short term test insects is not obvious.
