玉树地震灾区病媒生物监测结果分析

目的 了解玉树地震灾区病媒生物的种类、密度情况,为科学开展病媒生物控制提高可靠依据.方法 在每个灾民安置点选5顶帐篷(活动房、临时住所等),采用目测法监测蚊虫密度；在每个监测点选择厕所和垃圾堆(桶)、帐篷(活动房、临时住所等)内、外3类环境各5处,采用目测法监测蝇密度；鼠密度监测采用盗食法.结果 玉树地震灾区未发现蚊虫活动,蝇、鼠总体密度分别为0.69只/m2和4.12％；蝇密度6月最高,3类环境中垃圾堆和厕所的蝇密度较高；鼠密度5月较高,当代社区安置点的鼠密度相对较高.结论 蝇密度除6、7月较高,达到杀虫指标以外,蝇、鼠总体密度较低；根据监测结果,指导灾区在保护三江源生态环境和灾区人民健康的前提下,科学合理开展病媒生物控制,防止相关疾病的发生流行.

Analysis on vector surveillance in Yushu earthquake-stricken areas

Objective To determine the species composition and density of vectors in Yushu quake-stricken areas to inform vector control.Methods The mosquito and fly density was investigated by visual estimation for five types of habitat at five tents or mobile houses in each of the temporary shelter.The rodent density was measured by bite - stealing method.Results No mosquito activity was found in the areas.The densities of flies and rats were 0.69/m~2 and 4.12%,while the highest fly density was observed in June,as we...
