摘要:  枸杞线角木虱Bactericera gobica (Loginova)是一种严重危害宁夏枸杞Lycium barbarum L.的害虫,对枸杞的生长和产量造成影响甚大。在对宁夏中卫地区枸杞线角木虱的天敌调查中,我们发现一种寄生率较高的寄生蜂——枸杞木虱跳小蜂Psyllaephagus arenarius Trjapitzin。这是该种在中国首次记录,同时枸杞线角木虱也是该种的一个新寄主记录。本文对该种进行了描述,同时提供了形态特征图。

Abstract: Bactericera gobica (Loginova) is an important pest of medlar (Lycium barbarum L.), that can attack buds or tender leaves, causing damage as early leaf drop and fruit drop, and leading to big economic loss. In the investigation of natural enemies conducted in Zhongwei, Ningxia, China, we discovered a species of Psyllaephagus, P. arenarius Trjapitzin, which attacks B. gobica and has high parasitism rate. This is the first record of P. arenarius from China, and B. gobica also a new host record for P. arenarius. In this paper, the species P. arenarius was redescribed and illustrated with photomicrographs.
