摘　　要：目的 了解湖北省嗜人按蚊和中华按蚊的生态习性以及与疟疾发病的关系。方法调查各县（市）疟疾发病情况及当地传播媒介的种类和生态习性。结果湖北省疟疾流行与媒介的种类、栖息场所、吸血习性等有密切关系，通过调查发现嗜人按蚊人房密度为84．04％，中华按蚊密度为15，96％。嗜人按蚊的媒介能量平均高出中华按蚊44．47倍，嗜人按蚊区疟疾发病数占全省发病数的81．38%-93．84％。结论在嗜人按蚊存在的地区，疟疾发病较高。应根据媒介生态习性、分布特点及发病规律采取不同的抗疟措施。Objective To survey the relationship of A. anthrophagus, A. simensis with malaria morbidity. Methods The status of malaria morbidity, the species distribution and bionomic habits of anopheles vectors in Hubei province were surveyed. Resuits In Hubei province, there malaria prevalence was closely related with population density, habitats and human - biting behavior of vectors. The densities of A. anthrophagus and A. sinensis in human dwellings, were 84.04% and 15.96%, respectively. The average vector capacity of A. anthrophagus was 44.47 times higher than that of A. sinensis. The malaria infections in areas prevalent with A. anthrophagus was accounted for 81.38 % - 93.84 % of the total malaria cases in Hubei Province. Conclusion The malaria morbidity in A. anthrophagus areas is higher than that of areas of A. sinensis. In recently 10 years, the malaria is mainly prevalent in A. anthrophagus area in this province. It suggests that various malaria control strategies should be made based on the ecological habit, distribution of the vectors and the characteristics of malaria cases.
