目的掌握金华市城区主要病媒生物种群密度及其消长规律,为控制病媒生物的危害提供科学依据。方法采用诱蚊灯法监测蚊密度,笼诱法监测蝇密度,粘捕法监测蜚蠊密度,夹夜法监测鼠密度。结果2005-2007年金华市城区蚊平均密度为12.47只/人工小时,以淡色/致倦库蚊为优势蚊种,占捕获总数的94.46%,其次为骚扰阿蚊和中华按蚊,分别占3.65%和1.16%;蝇密度指数为50.03只/笼,优势种为大头金蝇、丝光绿蝇,分别占捕获总数的36.05%和24.56%;蜚蠊密度为126.74只(/100张·夜),以德国小蠊为优势种,占97.95%;捕鼠135只,鼠密度为0.33%,优势种为褐家鼠,占51.85%。结论淡色/致倦库蚊、大头金蝇和丝光绿蝇、德国小蠊以及褐家鼠是金华市城区防制的主要对象,要降低主要病媒生物密度,应根据它们的孳生、栖息习性及其季节消长特点,采取以环境治理为主的综合性防治措施。
Objective To understand the population density and its growth and decline pattern of major vectors in Jinhua City, and to provide a scientific basis for controlling the harm of vector organisms. Methods The mosquito density was monitored by mosquito lamp method. The density of flies was monitored by cage induction method. The density of cockroaches was monitored by sticking catching method. Results The average density of mosquitoes in Jinhua City from 2005 to 2007 was 12.47 / artificial hour, and the dominant species were Culex pipiens / Culex quinquefasciatus, accounting for 94.46% of the total number of catches, followed by Argiope mosquitoes and Anopheles sinensis, accounting for 3.65 % And 1.16% respectively. The density index of flies was 50.03 / cage, the dominant species were Drosophila melanogaster and Lucilia sericata, which accounted for 36.05% and 24.56% of the total number of captured flies, 126.74 (/ 100 fats · night) cockroaches, The dominant species was Blattella germanica, occupying 97.95% of the total; 135 rats were caught, the density was 0.33%, and the dominant species was Rattus norvegicus (51.85%). Conclusion Culex triturus / Culex quinquefasciatus, Kingfly and Fly green flies, Blattella germanica and Rattus norvegicus are the main control targets in urban area of Jinhua City. To reduce the density of major vector, we should base on their breeding, habitat and habitat Its seasonal growth and decline characteristics, to take environmental governance as the main integrated control measures.
