摘要 目的建立登革热监测预警系统,研制灵敏、高效、易行的登革热传播媒介白纹伊蚊在室内外环境的监测器械.方法根据白纹伊蚊的生态特点和美国疾病预防与控制中心诱卵器监测方法,结合捕蝇笼结构特点,设计具有引诱伊蚊产卵的器械,并在实验室及现场进行验证.结果在模拟现场,新型诱蚊诱卵器诱蚊阳性指数和诱卵阳性指数为100,每个诱蚊诱卵器平均诱捕成蚊12.25只,诱到虫卵1 369.2个;居民家庭诱蚊阳性指数达26.2,诱卵阳性指数达27.1,高于相同环境的容器指数,与布雷图指数相近;野外环境现场诱蚊诱卵阳性指数达18.6.结论新型诱蚊诱卵器具有良好的诱蚊诱卵效果,可作为登革热传播媒介室内外环境监测器械. Objective To establish the system of surveillance and forecast for dengue fever, a sensitive, effective, and feasible appliance was developed for the monitoring of dengue fever vector, Aedes albopictus in field. Methods According to the ecological characters of Aedes albopictus , and the structure of CDC(USA) ovitrap and housefly trap, we invented a Mosq ovitrap in which the mosquito would be attracted to oviposit, and would be caught. The attractive effect was tested in laboratory and in field. Results In laboratory both the positive mosquito and oviposition indexes of new Mosq ovitrap were 100 and the average adults and eggs were 12.25 and 1 369.2 in one trap,while in the dweller environment, the indexes were 26.2 and 27.1 respectively, and they were higher than the container index and similar to the Bretaeu index. The positive oviposition index was 18.6 in field. Conclusion As an appliance for monitoring vector of dengue fever, the new Mosq ovitrap had a high attractive effect for Aedes albopictus .
