摘要
目的了解兰州市安宁区主要病媒生物的种类、密度、季节消长情况,为有效预防和控制病媒生物的危害提供科学依据。方法监测方法采用鼠夹法、诱蚊灯法、诱蝇笼法和粘蟑纸法。结果 2014年兰州市安宁区鼠密度为0.5%,优势种为褐家鼠,高峰在2月和4月。蚊密度为2.74只/(灯·h),优势种为淡色库蚊,高峰在8月和9月。蝇密度为0.8只/笼,优势种为家蝇,高峰在5月和8月。蟑螂密度为0.39只/张,种类是德国小蠊,高峰在10月。结论基本掌握了兰州市安宁区主要病媒生物的种群、密度和季节消长规律。
Objective To understand the population composition,distribution and seasonal fluctuation of medical vectors in Anning District of Lanzhou City. Methods Mouse traps,lamp traps,cage traps and glue traps were used respectively to monitor the dynamics of rodents,mosquitoes,flies and cockroaches. Results The density of rats was0. 5%,and the dominant species was Rattus norvegicus,and the density peak appeared in February and April. The density of mosquitoes was 2. 74 /（ h·lamp）,and the dominant species was Culex pipiens,density peak in August. The density of flies was 0. 80 pieces per cage,and the dominant species was Musca domestica,density peak in May and August. The density of cockroaches was 0. 39 pieces per sheet,and the dominant species was Blattella germanice,density peak in October. Conclusion The population composition,distribution and seasonal fluctuation of medical vectors in Anning District of Lanzhou City were preliminary known.
