摘要: 目的:查明湖北省嗜人按蚊分布范围、生态习性与传疟作用。方法:全省定点和扩大范围调查嗜人按蚊分布,以卵块和成蚊形态鉴定蚊种,观察嗜人按蚊成蚊的生态及传疟能量。结果:全省调查42个县(市区场)287个乡镇1151个村,捕获按蚊57448只,鉴定46130只,其中嗜人按蚊3967只,中华按蚊42014只,八代按蚊149只,在19个县(市区场)104个乡镇696个村发现有嗜人按蚊分布。范围人口约1456万,面积4.6万km2。嗜人按蚊夜间活动高峰在0~2时,白天主要栖息在人房,其次为牛房及猪栏,构成比依次为84.40%、10.30%、9.25%,少数栖息于室外。该蚊吸人血指数为0.868。传疟能量5~11月平均为0.0667,比同域中华按蚊(0.0015)高44.47倍。结论:嗜人按蚊分布在大洪山麓与桐柏山之间的低山、丘陵、岗地及江汉平原结合部,是鄂中疟疾的重要传播媒介。

Abstract: Aim: To ascertain ecology,character and transmission of malaria in An.anthropophagus in Hubei province.Methods: To investigate An.anthropophagus in certain and extension areas in Hubei province. The identification of mosquitoes were by eggs,adults and observation the ecology and role of malarial transmission in An. Anthropophagus. Results: Investigation on character of distribution of An.anthropophagus was taken place in 1 151 villages of 287 towns of 42 counties in Hubei. There were 46 130 adults and eggs classified. It includes 3 967 An.anthropophagus, 42 014 An.sinensis, and 149 An.yatsushiroensis. The An.anthropophagus were scatter in 696 villages,104 towns and 18 counties with a population of about 14.56 million, about 46 000 km2. The An.anthropophagus located in east longitude 112°08′-113°51′,and north latitude 30°48′-32°25′with an elevation of 40-400 meters. There were two peaks in two rice harbests areas and one peaks in one rice harvest areas. The nocturnal feeding peak of An.anthropophagus were from 0-2∶00 o'clock . It was found that the composition of An.anthropophagus resting in the house,catter pen and pigsty were 84.40%, 10.30% and 9.25 % respectively. The vectorial capacity was 0.0667 which was 44.47 times as that of An sinensis. Conclusion:The An.anthropophagus was distributed in low hill,hilly land in Da Hong and Tong Be mountain chain. It is an important vector in malarial transmission.
