摘要
在北京的洋白蜡Fraxinus pennsylvanica Marsh.上发现了一种卷叶绵蚜,小枝端部卷叶里的蚜群在植物生长季节均有发生,绵蚜的寄生造成卷叶,部分卷叶会枯黄,影响美观。这是一种我国新记录的外来种,为原产于北美的洋白蜡卷叶绵蚜Prociphilus fraxinifolii(Riley,1879)。本文描述了该种绵蚜的鉴别特征,记录了其5种捕食性天敌(异色瓢虫Harmonia axyridis,大草蛉Chrysopa pallens,黑带食蚜蝇Episyrphus balteata,食虫齿爪盲蝽Deraeocoris punctulatus和斑楔齿爪盲蝽Deraeocoris ater)和3种访问的蚂蚁(日本弓背蚁Camponotus japonicus,丝光褐林蚁Formica fusca和黑褐草蚁Lasius niger)。
The green ash,Fraxinus pennsylvanica Marsh.,is infested with a leafcurl ash aphid in Beijing,China. Colonies of compact aphids live in curled leaves on the tips of twigs throughout the vegetation period. It causes malformations and some curled leaves turn to yellow. It was identified as an alien species,the Nearctic species Prociphilus fraxinifolii（ Riley,1879）. This is the first record of the species in China. The present paper described its diagnostic characteristics and recorded five predatory natural enemies（ Harmonia axyridis,Chrysopa pallens,Episyrphus balteata,Deraeocoris punctulatus,and Deraeocoris ater） and three attending ants（ Camponotus japonicus,Formica fusca,and Lasius niger） of this aphid found in Beijing.
