目的：了解目前我省疟疾暴发点与高发病村庄媒介按蚊种群密度与分布及其生态习性。方法：采用人诱与牛诱半通宵捕蚊法调查。结果：在山林区高发病村庄，捕获大劣按蚊和微小接蚊点,分别占捕蚊点的42．9％和57．1％；在平原丘陵区暴发点，均捕获微小按蚊，无捕获大劣按蚊。其中人诱捕获大劣按蚊、微小按蚊、中华按蚊和吉甫按蚊数，分别占捕蚊总数的9．9％、6.9％、54.5％和2．0％；牛诱捕获上述4种按蚊却分别占捕蚊总数的0％、3．3％、26．0％和12．3％。结论：在山林区高发病村庄主要传疟媒介为大劣按蚊和微小按蚊，而平原丘陵区暴发点仅为微小按蚊。
OBJECTIVE: To understand the current density and distribution of Anopheles vectors and their ecological habits in malaria outbreaks and high prevalence villages in our province. Methods: Survival and cattle induced semi-overnight catch mosquito survey. Results: Anopheles dirus and mosquitoes were captured in the high incidence villages in mountain forest area, accounting for 42.9% and 57.1% of the mosquito points respectively. Anopheles minimus was found in the outbreak areas in the hilly plain area, Catch anopheles sinensis. Among them, the numbers of Anopheles minimus, Anopheles minimus, Anopheles sinensis and Anopheles giganticola accounted for 9.9%, 6.9%, 54.5% and 2.0% of the total mosquitoes, respectively; Anopheles species accounted for 0%, 3.3%, 26.0% and 12.3% of the total number of mosquitoes, respectively. CONCLUSION: Anopheles mosquitoes and Anopheles minimus were the main vectors of transmission of malaria in villages with high prevalence in the mountain forests, while the outbreaks in the hilly plain were only Anopheles minimus.
