应用聚丙烯酰胺凝胶电泳分析中华按蚊和嗜人按蚊Ｅｓｔ、ＬＤＨ和ＰＯＤ３种同工酶谱，表明两蚊存在具有分类特征的酯酶带，但又是遗传关系十分相近的近缘种。中华按蚊分布全省各地，而嗜人接蚊局限于１４个县（市）２０５个自然村。以嗜人按蚊为主要媒介的地区，疟疾发病率、疟原虫率和间接荧光抗体率均显著高于以中华按蚊为主要媒介的地区，测试其媒介能量，嗜人按蚊是中华按蚊的１９倍，应是闽北山区的主要传疟媒介。 Analysis of isozyme patterns of Est, LDH and POD among Anopheles sinensis and Anopheles anthropophagus using polyacrylamide gel electrophoresis showed that there existed esterase bands with classified characteristics in both mosquitoes, but closely related species . Anopheles sinensis distributes throughout the province, while the anopheles mosquito limit is limited to 205 natural villages in 14 counties (cities). In the areas of Anopheles anthropophagus as the main medium, the incidence of malaria, the rate of Plasmodium and indirect fluorescent antibody were significantly higher than those of Anopheles sinensis as the main medium, and the media energy was tested. Anopheles anthropophagus was anopheles sinensis 19 times, should be the main malaria transmission media in northern Fujian.
