湖北省浅丘双季稻区嗜人按蚊生态及传疟作用

Studies on the Bionomics and the Role of Anopheles anthropophagus inmalaria Transmission in Low Mountain and Hilly Area, Hubei province

本文报道浅丘与平原接壤地带双季水稻区嗜人按蚊的生态习性及传疟作用，调查结果表明浅丘与平原交接地段嗜人按蚊成蚊主要栖息在人房内，室内平均密度为０．４６只／帐，在繁殖季节该蚊有两个季节性高峰，第１高峰为６月下旬至７月上旬，第２高峰为９月中、下旬，该蚊在人房、牛房、猪栏、室外诱蚊笼内所占的按蚊构成比依次为８４．０４％、１０．３０％、９．２５％、０％。该蚊嗜吸人血，传疟能量为０．１３７９。

In order to understand the role of Anopheles anthropophagus in malaria transmission in riceland of low mountain and hilly areas.The bionomics and role of An.anthropophagus in malaria transmission was carried out in Ying Chen city,Hubei province.The results showed that the anthropophagus adults stayed mostly in human houses and the average density was 0.46 per bednet.Two seasonal peaks were existed in a year, from late June to early July and from middie to late September.The proportion of An.anthropophagus in human houses, cattle sheds, pig sheds and the outside mosquito traps was 84.04%, 10.30%, 9.25% and 0.00% respectively.The vectorial capacity of An. anthropophagus Was 0. 1379.
