Abstract: In order to provide references for an in-depth understanding of genetics and evolution on the citrus psyllid in southern China, mitochondrial cytochrome coxidase I (COI) genes of 5 geographic populations were cloned, and genetic distance and phylogeny were analyzed. The results showed that 5 geographic populations had a very closely genetic relationship (0.0%—0.2%). The genetic distance of Guangzhou, Zhanjiang populations was 0. The genetic distance among Xiamen, Guilin and Nanning populations was also 0. The phylogenetic analysis based on COI showed that genetic differentiation between the five populations in southern China was low. In addition, there was no obvious correlativity between the geographic distance of populations and the level of homology distance comparing with other 21 populations in other districts.

Key words: citrus psyllid, mitochondrial COI gene, phylogeny, genetic differentiation

摘要: 柑橘木虱Diaphorina citri是重要的柑橘害虫,其传播的黄龙病对华南地区柑橘产业造成严重危害。为了解华南地区柑橘木虱不同地理种群间的遗传多样性和进化关系,测定该地区5个地理种群线粒体COI基因900 bp序列,对不同地理种群柑橘木虱遗传距离和系统发育进行分析。结果表明,5个地理种群柑橘木虱间的遗传距离小(0.0%~0.2%)。其中,广州种群和湛江种群的柑橘木虱之间的遗传距离,以及南宁种群、桂林种群和厦门种群的柑橘木虱之间的遗传距离均为0,序列间的相似度极高。基于COI基因系统发育分析显示,位于中国的5个柑橘木虱地理种群之间分化程度较低,与国外其他地区21个种群相比,各种群间的同源性与地理距离无显著相关性。
