目的了解辽宁各口岸医学媒介生物(蚊、蝇、鼠、螨、蜚蠊)的种群分布、季节消长及病原携带现状,为媒介传染病的流行病学分析和控制病媒生物的危害提供科学依据。方法成蚊监测采用人工小时法,蝇类监测采用笼诱法,蜚蠊监测采用蜚蠊诱捕器法,鼠类监测采用夹夜法,螨类监测采用革螨指数法。结果鼠形动物2科4属6种,褐家鼠为优势种群;蝇类5科18属41种,丝光绿蝇为优势种;蚊类3属14种,淡色库蚊为优势种;蜚蠊1科1属1种,为德国小蠊;螨1科1属1种,为耶氏厉螨。结论褐家鼠、丝光绿蝇、淡色库蚊和德国小蠊是辽宁各口岸媒介防控的主要对象,应当根据其孳生习性和季节消长规律,采取环境治理和药物控制等综合性防治措施。
Objective To understand the population distribution, seasonal fluctuation and pathogen carriage of medical vector organisms (mosquitoes, flies, rats, mites and cockroaches) at all ports of Liaoning and to provide a scientific basis for the epidemiological analysis of vector-borne infectious diseases and the control of vector-borne diseases . Methods The artificial mosquito method was used to monitor adult mosquitoes. Cage method was used to monitor flies, cockroach catcher was used to monitor the cockroaches, and nocturnal cats were used to monitor the mites. Results There were 6 species of 4 genera in 2 families and 2 dominant species in Rattus norvegicus; 41 species of 18 genera in 5 families; 5 dominant species in 18 genera and 5 dominant genera in 3 genera of Mosquito; dominant species of Culex pipiens pallens; 1 genus and 1 genus, for the German cockroach; mites 1 families and 1 genus, is Yeh-mili. Conclusion Rattus norvegicus, Lucilia serpina, Culex pipiens pallens and German cockroach are the main targets of media control in Liaoning ports. Comprehensive control measures such as environmental control and drug control should be taken according to their habit of breeding and seasonal fluctuation.
