    摘要:

    【目的】股带针蓟马,又称温室条带蓟马,是一种多食性农业害虫,寄主超过50种,在一些国家被列为检疫性生物。2020年9月,在北京发现其成虫和幼虫危害海芋叶片,本文介绍了其形态特征、分子鉴定数据、分布地区及寄主植物等数据,以期为其准确鉴定和防治提供参考。【方法】采用拍打法收集标本;采用非破坏性方法提取单头蓟马DNA,扩增线粒体细胞色素c氧化酶Ⅰ基因(COⅠ)的部分序列,进行分子鉴定和系统发育分析;制作永久玻片进行形态鉴定。【结果】结合形态和分子数据鉴定其为股带针蓟马,海芋是该种新记录的寄主植物。股带针蓟马与该属其他种的主要区别在于该种前翅的亚中部浅色带比端部暗带短。COⅠ分子序列分析表明,北京种群与国外种群聚集成一个分支,序列相似性高达100%。【结论】应采取进一步调查、监测和管理措施,防止该种外来有害蓟马的传播。

    Abstract:

    【Aim】The banded greenhouse thrips, Hercinothrips femoralis, is a polyphagous agricultural pest with more than 50 host plants and listed as a quarantine insect in some countries and regions worldwide. In September 2020, both the adults and larvae of this species were found to damage the leaves of Alocasia odora in Beijing, China. We provide information on their morphological and molecular characteristics, geographical distribution, and host plants for their identification and control. 【Method】 Specimens were collected by the stick-beating method; genomic DNA was extracted using nondestructive methods; partial sequences of the mitochondrial cytochrome c oxidaseⅠgene (COⅠ) were amplified for molecular identification and phylogenetic analysis; permanent slides were mounted with Canada balsam. 【Result】 The specimens were identified as H. femoralis through morphological and molecular methods. A. odora was the host plant of this alien thrips. H. femoralis is distinguished from other species of this genus by the submedian pale area of the forewing, which is shorter than that of the distal dark band. Molecular sequence analysis of the mitochondrial cytochrome c oxidaseⅠ(COⅠ) gene suggested that the Beijing population clustered in a branch with foreign populations, with sequence similarity as high as 100%. 【Conclusion】 Further investigations, monitoring, and management measures should be taken immediately to prevent the spread of this alien thrips.
