摘要: 外来入侵害虫刺槐叶瘿蚊Obolodiplosis robiniae (Haldemann) 原产北美洲东部, 2006 年在中国发现, 危害刺槐叶片, 严重影响刺槐的健康生长, 已经列入我国检疫性害虫名单。在河北省秦皇岛市野外调查, 发现了一种广腹细蜂科天敌——叶瘿蚊广腹细蜂Platygaster robiniae Buhl and Duso, 该寄生蜂属中国新记录种。野外观察表明其对刺槐叶瘿蚊最高寄生率达84.8%, 具有良好的生物防治应用前景。本文对该广腹细蜂的外部形态和初步观察的生物学特性进行了描述。

Abstract: The gall midge Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae) was just recently found in China, it caused severe damage to black locust, Robinia pseudoacacia L. The pest is native to North America. Because the pest threats the health of R. pseudoacacia, it has been listed in the quarantine list in China now. For biocontrol purpose we investigated its insect natural enemy. In Qinghuangdao city of Hebei province, O. robiniae populations are affected by a parasitoid, Platygaster robiniae Buhl and Duso in the family Platygastridae, which is a new record in China. Primary field investigation indicated that the highest parasitism rate of P. robiniae could reach 84.8%, and this wasp has high application value for biocontrol. The external morphology observed with scanning electron microscopy (SEM) and the tentatively observed biology of P. robiniae are described in the present paper
