警惕一种潜在的入侵性有害生物多孔曼粉蚧

【目的】明确北京口岸从泰国进口的红毛丹果实表皮中检出活体粉蚧的种类及其分类地位、分布、潜在入侵危害性等情况。【方法】通过形态特征和DNA条形码技术对截获样本进行比对鉴定,并结合相关文献对其进行综合分析。【结果】该粉蚧为多孔曼粉蚧Maconellicoccus multipori(Takahashi,1951),隶属于半翅目Hemiptera粉蚧科Pseudococcidae蔓粉蚧属Maconellicoccus。同时详细介绍了该粉蚧的形态特征,以及我国口岸对曼粉蚧属的截获情况,讨论了多孔曼粉蚧的检疫意义。【结论】口岸应对该虫引起足够的重视,加强针对该虫的检疫措施,严防该虫入侵我国。

Precautionary analysis of a potentially invasive pest Maconellicoccus multipori (Takahashi, 1951)

Aim] To clarify the species, classification status, distribution and potential invasion harmfulness of the live mealybug in the epidermis of rambutan fruit imported from Thailand at Beijing port.Method] Morphological characteristics and DNA barcoding were used to compare and identify the intercepted sample.Result] The mealybug Maconellicoccus multipori (Takahashi, 1951), belongs to the Hemiptera, Pseudococcidae and Maconellicoccus. The COI sequence of the mealybug with the serial number KY372754 (M. multipori) in GenBank was 99% consistent. The morphological characteristics of Maconellicoccus multipori were introduced. The intercept situation of Maconellicoccus in China was reviewed. And also the quarantine importance of the pest was discussed.Conclusion] The pest should be paid high attention by customs departments. Strengthening quarantine measures against to the pest is needed.
