红火蚁Solenopsis invicta Buren是重要的经济害虫,特别是在农业和生态系统危害方面.2004年底在广东和香港的部分地区发现红火蚁入侵.本文用线粒体细胞色素氧化酶Ⅰ(CO Ⅰ)基因对境内的13个种群进行了入侵蚁巢是否独立传入进行了分析.通过对共计28个蚁巢56个体的包含904个碱基的CO Ⅰ基因分析,发现入侵中国的红火蚁中存在3种单倍型.基于未修正的配对序列变异分析表明,单倍型Ⅱ与单倍型Ⅲ之间的变异最小.而香港种群同时具有这三种单倍型,是入侵中国的红火蚁种群中多样性最丰富的地区.这三种单倍型都分别在阿根廷红火蚁种群中有记录.同源性分析显示,中国的红火蚁可能起源于阿根廷或南美洲,而香港可能是所研究种群的第一入侵地点.

The red imported fire ant, Solenopsis invicta, is an invasive species of economic concern (primarily an agricultural and ecosystem pest). Such ant was found in some areas of Guangdong and Hong Kong at the end of 2004. By examining genetic variation of the mitochondrial cytochrome oxidase Ⅰ (CO Ⅰ) gene, we analyzed the colony introduction of 13 populations of such ant. A 904 bp fragment of the CO Ⅰ gene was sequenced for 56 individuals from 28 nests. Three haplotypes were obtained. Using the uncorrected pairwise sequence divergence, we found that the divergence between haplotype Ⅱ and haplotype Ⅲ was smallest. All three haplotypes were observed in the Hong Kong population, while only one or two haplotypes were observed in the other populations. Such data of the highest genetic diversity in Hong Kong population suggested that Hong Kong may be the original place of the ant invading other areas in China. All of the three haplotypes observed in Hong Kong population were reported in Argentina, and it is so inferred that the Chinese fire ant may come from Argentina or South America.
