摘要

[Objective] In order to construct the specific equine disease-free zone of of the Guangzhou Asian Games,to ensure that the equestrian events of Guangzhou Asian Games be smoothly held.[Methods] The species,quantities,distribution and seasonal variations of insects and wild animals in related zones were investigated from 2008 to 2010,and the collected samples of the insects and wild animals were tested in laboratory for related equine diseases.[Results] The investigations indicated that there were some mosquitoes,flies,horseflies,punkies,ticks,bats,wild birds and wild boars in equestrianism venue and peripheral regions of disease-free zone of the Guangzhou Asian Games,the laboratory results of Japanese encephalitis,vesicular stomatitis,Nipah virus disease,West Nile fever,and Trypanosomiasis evansi,were all negative.According to the investigations and test results,the risk assessments of insect and wild animal vectors in the prevalence of related equine diseases were made to confirm that the risk was relatively low or very low,and comprehensive prevention and control measures with prevention as major measures and insecticides application and environment managements as supplementary means were made on the basis of the risk assessment conclusions.[Conclusions] This research has laid a solid foundation for the successful building of the first specific equine disease-free zone in our country,ensured the smooth holding of the 16th equestrian competition in Guangzhou Asian Games.
