摘要 过去约20年间扶桑绵粉蚧Phenacoccus solenopsis Tinsley在许多国家造成严重危害。近年来该害虫传入我国,对农业生产构成严峻威胁。外来入侵物种的快速准确鉴定是科学研究及其管理的基础。本研究对来自海南三亚和陵水地区的扶桑绵粉蚧的线粒体细胞色素氧化酶I(mt COI)测序并与美国佛罗里达州的扶桑绵粉蚧序列进行了比较。系统发育树表明该物种存在两个遗传支系,即海南支系与佛罗里达支系;这两个支系的遗传距离约3%。这是利用mt COI分子标记对我国扶桑绵粉蚧的首次分子鉴定。这些结果提示:(1)扶桑绵粉蚧可能是至少含有两个隐存谱系或姊妹种的复合种;(2)新入侵我国海南三亚和陵水地区的扶桑绵粉蚧是该复合种内的一个隐存谱系或物种,且海南三亚和陵水种群可能不是来自美国佛罗里达州。扶桑绵粉蚧隐存谱系的发现对于该物种的分子鉴定及其入侵生态学研究具有重要意义。 The mealybug species,Phenacoccus solenopsis Tinsley has caused severe economic losses during the last two decades in many countries.Recently this alien invasive species has been introduced in China and threatened the agricultural production.The rapid and accurate identification of the species has been the basis of the scientific research and management of the alien invasive species(IAS).In this study,the mitochondrial cytochrome oxidase subunit I(mt COⅠ)of the P.solenopsis materials collected from Sanya Cit...
