摘  要：
利用分子生物学技术对内蒙古驯鹿未定种皮蝇蛆线粒体CO1基因种属特异性序列进行了研究。DNA核苷酸测序结果证实:该种皮蝇线粒体CO1种属特异性基因UEA7到UEA10特殊目标编码区域片段长度约为689 bp;种系发生进化树和同源性分析显示其与鹿皮蝇法国株同源性非常接近,因此确定内蒙古地区感染驯鹿的皮蝇蛆为鹿皮蝇(Hypoderma diana)。不同蝇种间差异性分析显示:皮蝇科(Hypodermatidae)与狂蝇科(Oestridae)之间序列差异明显,差异性为19.3%~25.5%;寄生于鹿的不同蝇蛆种间差异性为1.9%~25.5%;皮蝇属(Hypoderma)不同种间差异性为6.7%~18.7%;鹿蝇属(Cephenemyia)不同种间差异性为1.9%~9.6%;而同种不同株的鹿皮蝇差异性为6.0%;说明生物线粒体CO1基因核苷酸序列在一定程度上可反映出种属及株间在进化上的差异性。

摘  要：
The specificity of mitochondrial cytochrome oxidase 1(CO1)gene sequence of warble fly larvae of unknown species from reindeer in Inner Mongolia region of China were analyzed by molecular biological techniques.The results showed that the size of CO1 gene fragment from UEA7 to UEA10 was approximately 689 bp.The analysis of phylogenic tree showed that the unknown species from the reindeer in Inner Mongolia had high homology with Hypoderma diana France isolate.The differences analysis between the different fly species showed: the sequences between Hypodermatidae and Oestridae were obviously different,ranged from 19.3% to 25.5%.The divergences of different fly larvae in deer ranged from 1.9% to 25.5%.The divergences of Hypoderma.ranged from 6.7% to 18.7%.The divergences of Cephenemyia.ranged from 1.9% to 9.6% and the variation of the different Hypoderma diana strains was 6.0%.It suggested that the nucleotide sequences of the mitochondrial CO1 genes could indicate the phylogenetic relationships among different genera,species and strains to some extent.
