1984年7～9月,在四川省筠连县沐爱乡通过昆虫学和寄生虫学定量调查,比较了雷氏按蚊嗜人亚种与中华按蚊的传疟作用.观察期60天内当地居民发病率为8.51％(全部为间日疟).雷氏按蚊嗜人亚种和中华按蚊的昆虫接种率分别为0.003367和0.000185,按此比例推算当地疟疾病例中,由雷氏按蚊嗜人亚种传播的占94.3％,中华按蚊传播的占5.7％。结果证明,雷氏按蚊嗜人亚种为高效媒介,它的传疟作用相当于中华按蚊的20倍。
From July to September 1984, a quantitative survey of Entomology and Parasitology was conducted in Mu’ai Township, Junlian County, Sichuan Province to compare the transmission of malaria in Anopheles stephensi and Anopheles sinensis. During the observation period, The incidence rate of residents was 8.51% (all P. vivax) .Infective rates of A. relicts and A. sinensis were 0.003367 and 0.000185, respectively. According to this proportion, 94.3% were transmitted by the human being, while 5.7% were transmitted by the Anopheles sinensis. The results show that the Anopheles venom mosquito is an effective medium, its malaria transmission effect is equivalent to 20 times the Chinese Anopheles.
