摘　　要：刺槐叶瘿蚊广腹细蜂Platygaster robiniae Buhl and Duso(膜翅目:细蜂科)是我国外来有害生物刺槐叶瘿蚊Obolodiplosis robiniae(Haldeman)(双翅目:瘿蚊科)十分重要的寄生性天敌,为卵-幼虫跨期寄生蜂,专化性强,在自然抑制害虫虫口密度中起着非常重要的作用。为摸清刺槐叶瘿蚊广腹细蜂在我国的地理分布,探讨其与刺槐叶瘿蚊的相互关系,本文根据寄主刺槐叶瘿蚊在我国的分布范围,采用踏查的方法,对全国17个省、市、自治区的29个地区进行了调查。结果显示,刺槐叶瘿蚊广腹细蜂在其寄主分布区都有分布,分布范围在26°35.451′-43°53.482′N,103°51.816′-125°15.969′E,海拔4-1 097 m。Platygaster robiniae Buhl and Duso (Hymenoptera: Platygastridae) is an important and specialized natural enemy of the black locust gall midge Obolodiplosis robiniae (Diptera: Cecidomyiidae), an invasive insect pest in China. It is an egg-larvae parasitoid of the gall midge and plays a significant role in natural control of O. robiniae . To figure out the geographic distribution of P. robiniae and the relationship between the parasitoid and its host in China, field surveys were conducted in 29 sites of 17 provinces, cities and autonomous regions in China within the distribution range of its host O.robiniae . The results showed that P. robiniae was found in all areas where its host distributed. Based on the collection data, P. robiniae were found broadly distributed in the range of 26°35.451′- 43°53.482′N , 103°51.816′-125°15.969′E at the elevation in between 4-1 097 m in China.
