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。
Objective To comprehensively grasp the distribution of mosquito vectors in Chenzhu Town, Tongchuan City, analyze the harm degree of mosquito vectors and provide basis for scientific prevention and control. Methods Adult mosquitoes were investigated by mosquito lamp method and human-book method. The larvae examined the positive rate of hydrops in the external environment of houses, and evaluated the index of larvae, housing index and index of hundred larvae. Results The mosquito density of mosquitoes was 0.0874 / (lamp · h), mosquito density was 0.2018 / (lamp · h) in July. The highest density of adult mosquitoes in each environment was 0.1429 / (lamp · h), followed by residential houses, 0.1078 / (lamp · h). The net mosquito density was 7.4419 / (account.h). The adult mosquito density was the highest in August at 30.6000 / (account.h). The average residential container index was 14.48%, the highest in August (21.87%), the housing index of 35.88% and the household index of 76.08%. Conclusion There are a large number of breeding places for Aedes mosquitoes in the scenic spot of Chenlu Town, mainly in various water storage containers, and the density of Aedes albopictus is relatively high. Therefore, measures should be taken to remove the accumulated water and control the Aedes albopictus density.
