Abstract:

Objective To investigate the distribution of mosquitoes in Chenlu scenic spot of Tongchuan, Shaanxi province, China to provide guidance for mosquito control. Methods Lamp-baited trap and human-baited net trap were used for assessing the density of adult mosquitoes. The positive rate of water containers in the external environment of residential area was determined, and the container index, house index, and Breteau index were determined to assess the density of mosquito larvae. Results According to the data collected using lamp-baited trap, the mean density of adult mosquitoes was 0.0874 mosquito/lamp·hour; the density of adult mosquitoes was highest in July (0.2018 mosquito/lamp·hour) and in farm for tourism (0.1429 mosquito/lamp·hour), followed by residential area (0.1078 mosquito/lamp·hour). According to the data collected using human-baited net trap, the mean density of adult mosquitoes was 7.4419 mosquitoes/net·hour; the density of adult mosquitoes was highest in August (30.6000 mosquitoes/net·hour). In the residential area, the mean container index was 14.48%, and the container index was highest in August (21.87%); the house index and Breteau index of residential area were 35.88% and 76.08%, respectively. Conclusion There are plenty of breeding places for Aedes, especially various water containers, in the environment of Chenlu scenic spot, and the density of Aedes albopictus is the highest. Measures should be taken to remove accumulated water and control the density of Ae. albopictus.

摘要:

目的 全面掌握铜川市陈炉镇景区蚊媒分布情况,分析蚊媒危害程度,为科学防制提供依据。方法 成蚊调查采用诱蚊灯法和人帐诱法,幼虫检查民居外环境容器积水的阳性率,计算容器指数、房屋指数、百户指数评价幼虫密度。结果 诱蚊灯法蚊密度为0.0874只/(灯·h),成蚊密度7月最高为0.2018只/(灯·h)。各环境中以农家乐成蚊密度最高,为0.1429只/(灯·h);其次为民居,为0.1078只/(灯·h)。帐诱法蚊密度为7.4419只/(帐·h),成蚊密度以8月最高,为30.6000只/(帐·h)。民居容器指数平均为14.48%,以8月最高(21.87%),房屋指数为35.88%,百户指数为76.08%。结论 陈炉镇风景区环境中存在大量伊蚊孳生地,主要以各种储水容器为主,而且白纹伊蚊密度较高,应落实积水清除措施,控制白纹伊蚊密度。
