摘　　要：采用访问调查、踏查法和诱饵法等调查了嘉禾县不同生境(农田、村居、道路两侧、学校、小河旁、荒地)下红火蚁的发生情况。结果表明:红火蚁疫情发生区在嘉禾县石丘村呈中心辐射分布,可能是随建筑木料从广东携带至该村后蔓延传播,疫情发生区面积约8.91 hm^2,疫情潜在发生区36.20 hm^2,疫情发生区踏查发现蚁巢数量5 857个,蚁巢密度为657.35个/hm^2,达到严重发生程度;其中以荒地的蚁巢密度最大(0.38个/m^2),诱集的红火蚁数量最多(7 890只);各生境严重程度由高到低排列依次为荒地>农田>小河旁>道路两侧>村居>学校。最后针对嘉禾县红火蚁的疫情提出了2点建议。In order to explore the impact of invasive red imported fire ant(Solenopsis invicta Buren)in Jiahe County,Hunan Province andprovide basic data for the prevention and control of the pest,the scope and area of the epidemic,nest and active ant density of the ant wereinvestigated in different ecological environments,especially the farmland,village,roadside,school,riverside and wasteland in epidemicarea such as Shiqiu Village,Zhuquan Town in this study.The ant which distributed as hub-and-spoke at the village may be carried backin construction wood from Guangdong Province,and then spread away.The epidemic area was8.91hm2,and the potential epidemic areawas36.20hm2.The average nest number per square meter in different habitats was0.081,and the average number of lured ant per bottlewas194.57.The nest number per square meter,the proportion of lured ant to bait and the average number of the lured ant per bottle in thewasteland were0.38,82.14%and343.04respectively,which was the highest in the different habitats.In Jiahe County,there was seriousinvasion by the red imported fire ant and the effective measures must be adopted as soon as possible to control the pest.
