中国首次发现椰枣种子害虫棕榈核小蠹OA
First record of the date palm seed pest Coccotrypes dactyliperda in China
在我国近年来引进具有重要经济价值的果树椰枣Phoenix dactylifera上,发现一种严重危害其种子的害虫.采用传统形态学鉴定及线粒体细胞色素c氧化酶亚基I(cytochrome c oxidase subunit I,COⅠ)基因序列系统发育分析,明确该害虫的分类地位,并描述其形态特征.结果表明:该害虫与棕榈核小蠹Coccotrypes dactyliperda(Fabricius,1801)形态特征相符,并与棕榈核小蠹形成一个单系群.结合形态学与分子生物学特征,确定危害椰枣种子的外来有害生物为棕榈核小蠹.该虫为我国首次发现,研究结果可为该害虫的监测、准确鉴定及制定有效防治策略提供重要的科学依据.
A pest that seriously damages the seeds of Phoenix dactylifera,a fruit tree with important economic value introduced in China in recent years,was discovered.The taxonomic status of this pest were clarified with traditional morphological identification and phylogenetic analysis based on mitochondrial cytochrome c oxidase subunit I(COI)gene sequences,and the morphological characteristics were described.The results showed that the pest was consistent with Coccotrypes dactyliperda(Fabricius,1801)in morphological characteristics and formed a monophyletic clade with C.dactyliperda.Based on morphological and molecular characteristics,the invasive pest damaging date palm seeds was identified as Coccotrypes dactyliperda(Fabricius,1801).This is the first report of this pest in China,and the findings provide important scientific evidence for the monitoring,accurate identification,and the development of effective control strategies of this pest.
