摘　　要：为确定采集到的中国西藏阿里地区飞蝗的分类地位及其与其他地区飞蝗间的亲缘关系,扩增了中国4个地区飞蝗5个mtDNA蛋白基因共长2 974 bp的片段,基于这5个基因序列和片段全长分别分析了西藏阿里地区与新疆、河北、海南和非洲5个地区飞蝗间的遗传距离和亲缘关系。结果显示,西藏新疆阿里地区飞蝗与新疆、河北地区飞蝗间的亲缘关系明显近于其与海南和非洲地区飞蝗间的关系,文末对西藏阿里地区亚洲飞蝗分布的可能性进行了讨论。To confirm the taxon of Locusta migratoria L. in Ali region Tibet and the genetic relationship with L. m. migratorioides in Africa and migratory locusts in other major breeding areas of China, Xinjiang, Hebei, Hainan, 2974bp mitochondrial DNA including 5 protein gene sequences. The genetic distance between migratory locusts in 5 regions based on these 5 protein gene sequences and the phylogenetic tree constructed based on the 2974 bp sequences all showed that the migratory locusts in All region, had significantly closer relationship with L. rn. rnigratoria, living in Xinjiang and Hebei than with those in Hainan （L. m. rnanilensis）and Africa（L. rn. rnigratorioides）which indicated that the locust in All region L. m. migratoria.
