摘要：杏树鬃球蚧在新疆西天山野果林对野杏已造成严重危害。为调查其寄生性天敌,本文通过采集受害枝条和室内饲养,获得了寄生蜂标本,经形态学观察与DNA序列分析,确定其为食蚧蚜小蜂新种,将其命名为天山食蚧蚜小蜂Coccophagus tianshanensis Li&Yao sp.nov.,文中详细描述了其形态特征,拍摄了局部特征照片,提供了COI及28S序列,同时编制了世界寄生杏树鬃球蚧的食蚧蚜小蜂属种检索表。本研究发现了新疆西天山野果林重要害虫杏树鬃球蚧的新天敌,为进一步开展生物防治奠定了基础。
To investigate the natural parasitoid enemies of Sphaerolecanium prunastri,a scale insect which harms wild fruit forests in western Tianshan,Xinjiang,branches seriously damaged by S.prunastri were collected and cultured in glass jars for obtaining natural parasitoids.Coccophagus tianshanensis Li&Yao sp.nov.,a new species of Coccophagus(Hymenoptera:Aphelinidae)was gained and identified based on the morphological and molecular data.Morphological characteristics of C.tianshanensis are described in detail,and COI and 28S sequences are determined.In addition,a key to species of the genus Coccophagus in the world parasitizing S.prunastri was established.This investigation has found a potential natural enemy of the S.prunastri in the wild fruit forests of the West Tianshan Mountains,Xinjiang,and establishes a new natural enemy for biocontrol of this pest.
