根据线粒体COI基因片段分析,柑橘黑刺粉虱Aleurocanthus spiniferus (Quaintance)种群和茶园黑刺粉虱种群之间的遗传距离(0.185-0.247)明显高于柑橘黑刺粉虱不同地理种群之间的遗传距离(0.002-0.076),也明显高于茶园黑刺粉虱不同地理种群之间的遗传距离(0-0.053)。由此推断柑橘黑刺粉虱和茶园黑刺粉虱属于黑刺粉虱的不同生物型,或不同种的Aleurocanthus属粉虱。地理距离和柑橘黑刺粉虱遗传距离具有较大的相关性,同类寄主专化型黑刺粉虱,岳阳洞庭湖区地理种群与其他地区地理种群遗传距离最远。长沙不同柑橘品种上的黑刺粉虱种群之间遗传距离小于0.01。
According to the mitochondrial COI gene fragment analysis, the genetic distance (0.185-0.247) between Aleurocanthus spiniferus (Quaintance) population and T. glauca population was significantly higher than that between different geographic populations The distance (0.002-0.076) was also significantly higher than the genetic distance (0-0.053) between different geographical populations of B. persicae in tea plantations. It is concluded that the different species of T. tabaci and the tea planthopper Blackjack whitefly belong to the different species of B. tabaci or different species of Aleurocanthus. Geographical distance and citrus blackfly whitefly genetic distance has a greater correlation, the same host specialized black tick whitefly, Yueyang Dongting Lake geographical populations and other geographical genetic distance the most. The genetic distance between T. tabaci populations on different citrus cultivars in Changsha was less than 0.01.
