目的 2010-2011年通过对大学生运动会(大运会)相关场所主要病媒生物进行监测,掌握病媒生物的种群分布和密度消长情况,为病媒生物控制提供科学依据。方法成蚊监测采用CO2诱蚊灯法,伊蚊专项监测采用诱蚊诱卵器法,蝇类、鼠类监测采用笼诱法,蜚蠊监测采用粘捕法。结果大运会场馆蚊虫的优势种为淡色库蚊,占捕获总数的89.47%(476/532);蝇类优势种为大头金蝇,占捕获总数的37.83%(2428/6419),铜绿蝇占19.16%(1230/6419),棕尾别麻蝇占17.36%(1114/6419);鼠类优势种为褐家鼠,占捕获总数的88.37%(38/43);蜚蠊优势种为德国小蠊,占捕获总数的97.15%(477/491)。2011年主要病媒生物密度与2010年相比下降显著,在大运会期间均处于低密度水平,成蚊密度下降20.55%,伊蚊诱卵指数下降77.70%,蝇密度下降91.29%,鼠密度下降44.38%,蜚蠊密度下降73.10%。结论及时开展监测和控制使得大运会相关场所主要病媒生物密度大幅度下降,确保了大运会不受病媒生物危害影响。
Objective By 2010-2011, the main vectors of the venues related to the Universiade (Universiade) are monitored and the population distribution and density of vectors are monitored to provide a scientific basis for vector control. Methods CO2 mosquito lamp method was used to monitor adult mosquitoes, mosquito attractant method was used to monitor the mosquito, mosquito-trap method was used to monitor flies and mice, and stick catcher was used to monitor cockroaches. Results The predominant species of mosquitoes in the venues of the Universiade were 89.47% (476/532) of the total number of captured mosquitoes, and the dominant flies were 37.83% (2428/6419) and 19.16% (1230/6419) and brown flies accounted for 17.36% (1114/6419). Rattus norvegicus was the dominant species in Rattus norvegicus, accounting for 88.37% (38/43) of the total catches; the dominant species was Blattella germanica 97.15% (477/491) of the total captured. In 2011, the main vector bio-density decreased significantly compared with that in 2010, both at the low density level during the Universiade, the adult mosquito density decreased 20.55%, the Aedes albopictus index decreased 77.70%, the flies density decreased 91.29% and the mouse density decreased 44.38 %, Cockroach density decreased by 73.10%. Conclusion The prompt monitoring and control make the density of main vectors of Universiade related places drop significantly, ensuring that the Universiade will not be affected by the vector biohazards.
