摘要
目的调查黑龙江省3个监测点2006-2008年鼠、蚊、蝇和蜚蠊等病媒生物的种群构成和密度,为病媒生物防制提供科学依据。方法鼠和蜚蠊监测分别采用夹夜法和粘蟑纸法,全年监测;成蚊和蝇类监测分别采用诱蚊灯法和笼诱法,5-10月监测。结果2006-2008年鼠密度分别为2.02%、2.17%和2.36%,农村自然村鼠密度最高,以褐家鼠为优势鼠种;成蚊密度3年分别为18.03、7.36和2.58只﹙/灯·h),牲畜棚密度最高,以中华按蚊、三带喙库蚊和淡色库蚊为优势蚊种;蝇密度3年分别为24.90、14.91和8.69只﹙/笼·d),农贸市场密度最高,以蝇科和丽蝇科蝇种为优势种;德国小蠊密度3年分别为3.05、3.71和1.91只/张,侵害率分别为23.35%、26.05%和23.75%,均以农贸市场最高。结论通过3年监测掌握了黑龙江省监测点主要病媒生物的种群构成和密度动态,监测工作应继续开展。
Objective To determine species composition and densities of rodents,mosquitoes,flies,cockroaches and other vectors at three monitoring sites in Heilongjiang province from 2006 to 2008,providing scientific evidence for the development of vector control. Methods Night traps and sticky traps were used to monitor rats and cockroaches throughout the years; lamp traps and cage traps were used for mosquitoes and flies from May to October each year. Results The rat densities reached 2.02%,2.17% and 2.36% from 2006 to 2008,respectively,the highest found in rural villages,and the dominant species being Rattus norvegicus. The densities of adult mosquitoes reached 18.03,7.36 and 2.58 per lamp hour in the three years,respectively,the highest density found in livestock sheds,with Anopheles sinensis,Culex tritaeniorhynchus and Cx. pipiens pallens as the dominant species. The fly densities were 24.90,14.91 and 8.69 per cage day,respectively,the highest found in farmers＇ markets,the dominant species being Muscidae and Calliphoridae. The densities of Blattella germanica reached 3.05,3.71 and 1.91 per sticky sheet,the encroachment rates being 23.35%,26.05% and 23.75%,respectively,with the highest density found in farmers＇ markets. Conclusion The 3-year monitoring program revealed the species composition and population dynamics of major biological vectors in Heilongjiang. Further surveillance and monitoring would be necessary.
