对蟑螂进行化学防制后产生的害虫抗药性问题,日益引起人们的关注。为了解本地常见蟑螂对杀虫剂的敏感性和抗药性,建立抗性监测基线材料,为防制对策提供依据。我们用七种杀虫剂对长沙市德国小蠊、美洲大蠊的LD_(50)、KT_(50)进行了测定,现报告如下:
Pesticides resistant to cockroaches after chemical control have attracted more and more attention. In order to understand the common cockroach insecticide sensitivity and drug resistance, the establishment of resistance monitoring baseline materials to provide the basis for the prevention and control measures. We used seven kinds of insecticides to determine the LD_ (50) and KT_ (50) of Blattella germanica and Periplaneta americana in Changsha. The results are as follows:
