河南省卫生杀虫剂使用现状调查

Investigation on the application of public health insecticides in Henan

目的掌握河南省卫生杀虫剂的使用现状,为科学使用卫生杀虫剂提供依据。方法采用现场调查法对河南省内病媒生物防治机构使用的和商超百货中销售的卫生杀虫剂使用情况进行调查,统计分析其品种数量及使用方法等情况。结果目前河南省内使用的卫生杀虫剂的主要成分以拟除虫菊酯类为主,配方以多种有效成分复配为主,毒性以微毒和低毒为主,防治对象以蚊、蝇、蟑螂和蚂蚁为主。结论拟除虫菊酯类化合物占据了河南省卫生杀虫剂市场的主要份额,病媒生物防治机构所使用的卫生杀虫剂向科学化、专业化发展,商超百货中所销售的卫生杀虫剂更倾向于安全、广谱和易用。同时,杀虫剂的使用情况与主要病媒生物抗药性的发生有相关性,今后应加强对卫生杀虫剂的依法管理,使卫生杀虫剂的使用更加合理规范。
