摘要:

目的 了解埃及伊蚊、白纹伊蚊在北海口岸的密度、季节分布规律。方法 采用人工小时法对成蚊进行监测,对幼虫的监测分别采用指数调查法、集卵器法和100 ml记数法。结果 在北海港捕获的697只及铁山港捕获的317只伊蚊成虫及两口岸所监测的幼虫,经鉴定均为白纹伊蚊。两地伊蚊成蚊平均密度分别为17.2和7.4只/人工小时,伊蚊幼虫的房屋指数、容器指数、布雷图指数、诱器指数及100 ml记数法幼虫密度指数分别为4.0%和13.0%,19.2%和27.2%,5.0和17.2,12.0%和23.2%,2.0和2.8条/100 ml。结论 两地伊蚊密度及其幼虫相关指数较高,提示口岸存在登革热流行的潜在危险。通过调查,初步摸清了北海口岸伊蚊的种类构成、密度和幼虫相关的指数等情况,为进一步做好口岸埃及伊蚊、白纹伊蚊的防制以及登革热防控提供技术数据。

Abstract:

Objective To investigate the density and distribution of Aedes aegypti and Ae. albopictus with seasons at the Beihai international port. Methods The labor hour method was used for surveillance of adult mosquitoes, with the index number method, the egg apparatus method, and the 100 ml counting method employed for larva surveillance. Results A total of 697 adult Aedes were captured in Beihai port with 317 adult Aedes sampled in Tieshangang port. All the adult Aedes and larvas collected in the two ports were identified as Ae. albopictus, and the average density of adult Aedes in Beihai port and Tieshangang port was 17.2 and 7.4 per labor hour respectively. The value of HI, CI, and BI of larva Aedes was 4.0% and 13.0%,19.2% and 27.2%,and 5.0 and 17.2, with an ovitrap index of 12.0% and 23.2%, and a larvas Aedes density of 2.0 larvae/100 ml and 2.8 larvae/100 ml at the two ports respectively. Conclusion There exist high density of adult Aedes and index of larvae Aedes in the two ports, suggesting that there is a high potential risk for dengue prevalence. The basic information about species of Aedes, the density and the larvae, etc. in the ports should be taken into account to better develop further control and preventive measures againstAe. aegypti and Ae. albopictus, and dengue epidemic.
