摘要
目的了解山东省中华按蚊生态习性和对杀虫剂的抗性状况,为山东省蚊传疾病的防控提供科学依据。方法 2008-2011年选择山东省微山县作为中华按蚊监测点,采用夜间室外通宵帐内人饵诱捕法进行密度和季节变化调查;采用WHO生物测定方法,测定不同地区中华按蚊对4种杀虫剂的抗药性。结果 2008-2011年山东省微山县疟疾媒介监测点捕到中华按蚊,其密度高峰出现在7月;部分地区中华按蚊对溴氰菊酯产生抗性(抗性级别为R),对三氯杀虫酯、残杀威和氯氰菊酯仍为敏感或产生初步抗性。结论疟疾防治中仍应继续加强媒介的监测与控制,警惕因中华按蚊密度升高而致疟疾疫情回升。
Objective To investigate the habits and insecticide resistance of Anopheles sinensis and provide a scientific basis for the control of mosquito-borne diseases in Shandong province, China. Methods During 2008-2011, we chose Weishan county of Shandong province as the An. sincnsis monitoring site and carried out seasonal surveys using outdoor bait trapping method overnight. The WHO bioassay method was used to test the resistance of An. sinensis to four insecticides. Results According to the situation at the monitoring site during 2008-2011, the An. sinensis density peaked in July. In some areas of Shandong province, An. sinensis had evolved resistance to dehamethrin （resistance level： R） and was still susceptible or developed an initial resistance to aeetofenate, propoxur, and eypermethrin. Conclusion AAs for malaria control, the monitoring and control of vector mosquitoes should he strengthened in ease that rising An. sincnsis density may cause malaria epidemic to return.
