| 摘 要： | 调查研究了红火蚁在特定的生态环境类型中的自然传播扩散规律．结果表明在局部区域传入8年后，红火蚁扩散面积约为226hm^2，扩散边界分别为：向河的上游扩散至262m处，向河的下游扩散至3770m处．红火蚁在几种生境类型中的为害程度也不相同，大小依次为田埂〉河堤〉路边〉房屋周围空地〉河床．红火蚁在该区域的扩散速度为187．9m／年，同时，红火蚁蚁巢在扩散过程中向源头有明显的聚集倾向．

| Abstract: | The location expansion of the red imported fire ant, Solenopsis invicta Buren,in a special ecology system were investigated and analyzed.The result showed the square area of the infestation was up to(226 hm~2) about 8 years after it was introduced to this area;Expansion distance were as follows: it spread to upper and lower reaches with the distance of(262) and(3 770 m) respectively.Active mounds densities were different among different types of habitat,with field bank>riverbank>roadside>village >riverbed. Average expansion speed of red imported fire ant was(187.9 m/year) in this area. |
