摘要
目的掌握宜昌市城区常见病媒生物种群及季节消长规律,为科学制定病媒生物防治方案提供有力依据。方法采用夹夜法监测鼠密度,诱蚊灯法监测蚊密度,笼诱法监测蝇密度,粘捕法监测蟑螂密度。结果宜昌市城区鼠类以褐家鼠、小家属为优势鼠种,分别占捕鼠总数的67.44%和27.91%;蚊类以致倦库蚊、骚扰阿蚊、白纹伊蚊为优势种,分别占捕获总量的40.78%、25.22%、18.07%;蝇类以家蝇、丝光绿蝇、巨尾阿丽蝇为优势种,分别占捕蝇总数的39.66%、15.76%和13.55%;蟑螂以德国小蠊、美洲大蠊为优势种,分别占捕蟑总量的59.17%、25.00%。4种病媒生物密度均有明显的季节性,5-9月为活动高峰期。结论根据不同季节、不同生境,采用科学方法防控病媒生物。
Objective To investigate the population and density of main vector in urban area of Yiehang city. Methods The rat density was monitored by night traps, mosquito density by the light traps, fly density by cage traps and cockroach density by the glue traps. Results Major rat species were Rattus norvegicus（67.44% ） and Mus musculus（27.91% ） ,major mosquito species were Culex pipens quinquefasciatus （40.78%） ,Armigeres subalbatus （ 25.22% ） and Aedes albopictus（ 18.07% ） ,major fly species were Musca domestica（ 39. 66% ） ,Lucilia sericata（ 15.76% ） and Aldrich# na grahami（ 13.55% ） ,major cockroach species were Blattella germanica（ 59.17% ） and Periplaneta americaru,（ 25. 00% ）. The density of main vector was rather higher from May to September. Conclusion It is necessary to take scientific method for controlling vector according to different season and environment.
