摘要
在广西北流地区,采用饵诱法调查了红火蚁入侵对当地蚂蚁群落的影响.对入侵区与未入侵区比较发现不同生境下,红火蚁入侵使本地蚂蚁的个体数量明显降低,丰富度、多样性和均匀性指数均下降,优势度指数升高,红火蚁成为优势种.表明红火蚁入侵对本地蚂蚁群落造成了一定程度的影响.必须加强红火蚁检疫和危害区的普查力度,发现新蚁巢及时处理,同时尽快研制出防治效果更好的药剂,防止危害区域进一步扩大.
The effects of the invasion of the imported fire ant, solenopsis invicta on the communities of the native ants were investigated by bait methods in BeiLiu, GuangXi from Sept. to Oct. , 2005. The results showed that R, J, H＇ index of ants in the invaded sites were lower, while S index of ant was higher than those in the non invaded sites, and the imported fire ant was the dominant species. The results implied that the invasion of the imported fire ant had serious influences on the native ant communities. Therefore, it is very important to inspect the imported fire ants, to survey the invaded areas and produce new pesticides as soon as possible in order to prevent their expansion further.
