摘要:

目的 通过对辖区世博会园区建设前(2006-2008年)连续3年的主要病媒生物监测,了解其消长情况和种群构成,为2010年世博会控制病媒生物提供科学依据。方法 蚊虫监测采用CO2诱蚊器法、紫外线灯诱蚊器法和诱卵器法,成蝇监测采用笼诱法,鼠类监测采用鼠夹法。结果 连续3年监测显示,蚊密度2006年显著低于2007年和2008年;蝇密度2008年最低,为18.13只/笼,2006年和2007年分别为39.31和34.17只/笼;鼠密度3年基本持平。共捕获蚊类5种4781只,其中优势蚊种为淡色库蚊(占74.75%),其次为白纹伊蚊(占24.83%);捕获蝇类16种11 447只,优势蝇种为丝光绿蝇(占44.96%),其次为大头金蝇(占28.98%);捕获鼠类2种34只,其中黄胸鼠占76.47%,褐家鼠占23.53%。结论 环境的改变和卫生管理情况,对病媒生物密度有较大的影响;该地区主要病媒生物将对世博会的召开存在潜在危害。

Abstract:

Objective To determine the seasonal fluctuation and population composition of  major vectors by a 3-year surveillance in the Shanghai World Expo area at Luwan district in the early period of construction (2006-2008), providing science evidence for vector control strategies for 2010 Expo. Methods CO2 traps, light traps and ovi-traps were used for mosquito monitoring, cage traps for fly monitoring, and snap traps for rat monitoring. Results Surveillance results indicated that the density of mosquitoes in 2006 was significantly lower than that in 2007 and 2008. The density of flies in 2008 was the lowest, being 18.13/cage, as compared to 39.31/cage in 2006 and 34.17/cage in 2007, respectively. No significant change in rat density was found during the three years. A total of 4781 mosquitoes of 5 species were captured, the dominant species being Culex pipiens pallens (74.75%), followed by Aedes albopictus (24.83%). A total of 11 447 flies of 16 species were captured, Lucilia sericata being the dominant species (44.96%), followed by Chrysomya megacephala (28.98%). About 34 rats of 2 species were captured, among which Rattus tanezumi accounted for 76.47% and R. norvegieus accounted for 23.53%. Conclusion Environmental changes and sanitation management exert great impact on vector density. Potential hazards of vectors shall be noticed in the Expo area.
