摘　　要：目的通过对无锡、南京和徐州3个市病媒生物的调查,分析江苏省2002-2007年鼠、蚊、蝇和蜚蠊的发生动态,为江苏省病媒生物防治及其传播疾病的控制提供依据。方法鼠和蜚蠊密度全年监测,分别选择夹夜法和粘蟑纸法;成蚊密度和蝇密度监测时间为4-11月,分别选择人工小时法和笼诱法。结果江苏省蚊、蝇和蜚蠊密度2002-2007年年际间消长呈单峰型曲线,高峰值出现在2005年或2006年;鼠密度逐年下降;优势种淡色库蚊构成比呈下降趋势;白纹伊蚊、黄胸鼠构成比总体呈逐年上升,2007年分别在10%和25%左右;优势种德国小蠊构成比越来越高,2007年高达97%。2002-2007年逐月密度分析,蚊类在7月和9月出现2个高峰,蝇类6-9月呈单高峰且高峰值在9月,蜚蠊在8-9月出现高峰,鼠类在各年每月间波动较大,高峰值多出现在3月和8月。结论2007年江苏省对病媒生物的控制有效,但仍需加强病媒生物高峰季节前的控制,同时白纹伊蚊和黄胸鼠有可能成为次优势种,与此相关的传播疾病危险性增强。建议加强对病媒生物及其传播疾病的长期监测、预警、控制对策和措施的研究工作。Objective To analysis annual dynamics of vectors such as rats, mosquitoes, flies and cockroaches in Jiangsu province from 2002-2007 by studying the regularly monitoring data of vectors in Wuxi city, Nanjing city and Xuzhou city. Methods The night trapping and cockroach paste methods were used for the monitor of rats and cockroaches density. The men-hour and eage-trapping methods were conducted to monitor the density of mosquitoes and flies from April to November, respectively. Results Annual density dynamic of mosquitoes, flies and cockroaches was single-peak curve from 2002 to 2007 and the peak appeared in 2005 or 2006. The density of rats decreased year after year and the constituted ratio of the dominant mosquito Culex piens pallens tended to reduce. The constituted ratio of Aeries （Stegomyia） albopictus and Rattus norvegicus （Berkenhout） increased yearly and reached about 10% and 25% respectively in 2007. Blattella germanica （Linnaeus） was the dominant species and its constituted ratio reached 97 % in 2007. According to the analysis data monthly of vectors from 2002 to 2007, the density of mosquito had two peaks, and the peak time was in July and September. The flies density had only one peak from June to September, which mainly centralized in September. The peak of cockroach density was from August to September. That of rat fluctuated greatly every month and its peak time was in March and August. Conclusion The risk of vector -borne disease might be worse than before because of the change of vector population and its structure. It should strengthen monitoring and control of vectors and vector-borne diseases in Jiangsu province.
