目的 :查明嗜人按蚊生态习性及吸血趋性 ,为制定疟疾防制措施提供科学依据。方法 :7～ 9月每旬 1次 ,调查嗜人按蚊在人房、牛栏、猪栏内密度 ,室外人帐诱蚊密度及季节和夜间活动高峰。调查该蚊对不同宿主吸血趋性和栖性、吸血习性。结果 :嗜人按蚊在人房内平均密度为 5 .70只 5 0顶 ,室外人帐诱 7.44只 (人·半通宵 ) ,牛栏 6.41只 (人工·h) ,猪栏 2 .3 7只 (人工·h)。嗜人按蚊季节高峰为 8月下旬至 9月上旬 ,夜间活动高峰为 2 3时～ 1时 ,叮人率为5 .0 493。吸血习性为 0 .2 40 6,比中华按蚊高 7.76倍 ,趋吸人血蚊占 89.75 %。传疟能量为 1.73 15 ,比中华按蚊高 8.2 5倍。结论 :嗜人按蚊主要栖息在人房 ,趋吸人血 ,是主要的传疟媒介。
Objective: To identify the anopheles anthropophagus ecological habits and vampire tendency, to provide a scientific basis for the development of malaria control measures. Methods: From July to September every ten days, the anopheles anthropophagus density in the human, oxen and pigsty, density of mosquitoes in outdoor decking and peak season and night activities were investigated. Investigate the mosquito to different hosts vampire tendency and habitat, vampire habits. Results: The average density of Anopheles anthropophagus in the human room was 57.50 and the outdoor person account was 7.44 (half night). There were 6.41 cattle (h) and 2.37 Only (artificial · h). The season of Anopheles anthropophagus peaked from late August to early September, and peak night activities ranged from 2300 to 1, leaving a rate of 5.0493. The blood-sucking habit was 0.2406, 7.76 times higher than that of Anopheles sinensis, and 89.75% of the sucking human mosquitoes. The malaria energy is 1.73 15, 8.25 times higher than that of Anopheles sinensis. Conclusion: Anopheles anthropophagus mainly inhabit the human room and inhale human blood, which is the main vector of transmitting malaria.
