2009-2011年绵竹市蚊、蝇、鼠和蟑螂密度监测

Density Monitoring of Mosquitoes,Flies,Mice and Cockroaches in Mianzhu,2009-2011

目的了解绵竹市蚊、蝇、鼠和蟑螂季节消长规律及种群构成,为制定防制对策,控制危害提供科学依据。方法蚊密度监测采用诱蚊灯法,蝇密度监测采用笼诱法,鼠密度监测采用夹夜法,蟑螂密度监测采用粘捕法。结果2009-2011年监测平均蚊密度1.22只/灯.小时,致倦库蚊为优势蚊种;平均蝇密度2.41只/笼,家蝇为优势蝇种;平均鼠密度1.27%,四川短尾鼩为优势鼠种;平均蟑螂密度0.78只/张,德国小蠊为优势种。蚊、蝇、蟑螂密度高峰在7-9月,鼠密度无明显季节高峰。不同年度鼠密度差异具有统计学意义,不同场所蚊、蟑螂密度差异具有统计学意义。结论近3年绵竹市蚊、蝇、鼠、蟑螂密度和种群构成无明显变化。

Objective To identify the density characteristics of mosquitoes, flies, mice and cockroaches in each season and their population composition, thus to provide scientific evidence for establishing prevention and control strategies. Methods Mosquito - trapping lamps were employed to for monitoring mosquito density, and successively ： fly - trapping cage for fly density, clamp - biting for mouse density and glue - catching for cockroaches density. Results The mean mosquito density was 1.22/lamp/h, and Culexfatigarts were the dominant ones; the mean fly density was 2.41/cage, and Musca domestica are the dominant ones; the mean mouse density was 1.27% , and Sichuart short -tailed shrew were the dominant ones; the mean cockroaches density was 0. 78/piece, and the blattella germanica were the domi- nant ones. The peak season for density of mosquitoes, flies and cockroaches were between July and September, while the mouse density had no evident season peaks. The mouse density differences among different years had statistical meanings, and the mosquito and cockroaches density differences among different places had statistical meanings. Conclusion During 2009 -2011, there is no evident change in the four pests density and population composition.
