| 摘 要： | 橘小实蝇Bactrocera dorsalis(Bactrocera)(Hendel)是我国重要的检疫性害虫,对果蔬生产及其国际贸易造成很大影响。作者运用微卫星分子标记技术,用6对微卫星引物对采自我国福建、广东、云南3个地区及邻近国越南橘小实蝇种群间的遗传关系进行了初步分析,结果显示上述4个橘小实蝇地理种群间存在一定的遗传差异,地理隔离是造成这一差异的主要原因。

| Abstract: | The oriental fruit fly,Bactrocera(Bactrocera) dorsalis(Hendel),is the important quarantine pest in China,creating problems not only for the production of fruits and vegetables but also the relative international trade.Six microsatellite markers were utilized in this study to assess the genetic polymorphism of oriental fruit fly primarily.Sampled populations come from Fujian,Guangdong,Yunnan and Vietnam.The results indicated that genetic differentiation exists among the four populations.The main reason of the genetic differentiation should be related to geographic isolation. |
