摘　　要：目的探讨嗜人按蚊在云南省昭通地区的分布和防制后的变化特征。方法通过资料收集分析,了解云南省20世纪80年代以来嗜人按蚊的分布范围、种群密度和传病关系;在5个乡12个村调查了解该蚊的分布特征;选择2个监测点开展防制后的种群密度监测。结果嗜人按蚊分布于全省35个县,但主要在滇东北8个县起传疟作用,其影响人口占全省人口的8.0%。嗜人按蚊防制后的平均密度为0.2只/人工小时,比防制前下降了99.5%～99.3%;平均50顶蚊帐的密度为0.08只;半通宵叮人率为0.13只/(人·夜)。8个嗜人按蚊传播县防制后期有5个继续发现嗜人按蚊,疟疾发病率亦由1980年的10.32/万下降到1997年的1.01/万。结论采用DDT滞留喷洒和菊酯类浸泡蚊帐效果显著,经控制后的嗜人按蚊分布范围、密度明显下降。Objective To explore the relationship of malaria transmission with Anopheles anthropophagus and its change characteristics after malaria control measures. Methods To understand the relation between An.anthropophagus distributing range, species density and malaria transmission through collecting and analyzing the data from field investigation in 12 villages of 5 townships for their distributed features in Yunnan province since 1980s. Two sentinel sites have been chosen to carry out species density monitoring after malaria control measure. Results An.anthropophagus distributed in 35 counties in Yunnan but only in 8 counties were found as vector of transmission malaria and accounted for 8% population of Yunnan. Average density for per hours was 0.2 and have decreased 99.5% 99.3% compared with before malaria control measure. The density of nets was 0.08 per net. Biting rate of half night was 0.13 per person per night. Only five of the 8 counties which An.anthropophagus can transmit malaria found malaria continually after malaria control measure. The malaria incidence also decreased from 10.32 per ten thousand people in 1980 to 1.01 per ten thousand people in 1997 in the 8 counties. Conclusion The malaria control measure of DDT residue spraying and insecticide treating nets are suit for vector control in these area.
