海南省应用溴氰菊酯浸泡蚊帐的灭蚊防疟效果

EFFECT ON MALARIA AND MOSQUITO CONTROL BY BEDNETS IMPREGNATED WITH DELTAMETHRIN IN HAINAN PROVINCE

本文报告海南省1990～1992年采用溴氰菊酯浸泡蚊帐替代DDT室内滞留喷洒作为疟疾综合性防治措施中防制媒介的主要措施的防疟结果。在以微小按蚊为主要传疟媒介的4个市县,发病率、居民带虫率、发热病人原虫率分别下降了53.61％、85.95％和46.11％;在以大劣按蚊为主要传疟媒介的10个市县,上述指标分别下降了51.05％、39.14％和60.92％。微小按蚊和大劣按蚊密度分别下降了95.46％和74.46％。证明溴氰菊酯浸泡蚊帐灭蚊防疟效果显著。

This paper reports the result of the extensive use of bednets impregnated with deltamethrin in 4 counties (cities) with An. minimus as main vector and 10 counties (cities) with main vector of An. dirus in Hainan Province. Compared with 1989, in An. minimus endemic area, the incidence rate, parasite rate in residents and fever cases reduced 53.61%, 85.95% and 46.11%, while in An. dirus endemic area, the reduction rate were 51.05%, 39.14% and 60.92% respectively. The density of An. minimus and An. dirus dropped by 95.46% and 79.46%. The results showed that the bednets impregnated with dehamethrin had remarkable malaria and mosquito control effect.
