摘　　要：三叶草斑潜蝇是我国重大入侵害虫之一,主要分布在热带和亚热带地区,可造成巨大的经济损失。寄生蜂作为膜翅目昆虫的一大类群,在害虫生物防治过程中发挥重要作用。据此,笔者于2021年10—12月在海南省各市县开展三叶草斑潜蝇寄生蜂资源普查时发现一种新的三叶草斑潜蝇幼虫寄生蜂。通过形态学鉴定确定该蜂为膜翅目Hyrmenoptera茧蜂科Braconidae蝇茧蜂亚科Opiina亮蝇茧蜂属Phaedrotoma的一个在中国尚未报道的新种,并命名为斑潜蝇亮蝇茧蜂Phaedrotoma sp.2。基于线粒体COI基因的分子进化树结果显示其与亮蝇茧蜂属寄生蜂聚为一类。本研究为后期三叶草斑潜蝇寄生蜂的人工扩繁打下基础,并有助于推动该蜂在田间害虫生物防治中的应用。Liriomyza trifoliata is one of the major invasive pests in China and is mainly distributed in tropical and subtropical areas,causing huge losses.Parasitic wasps,a large group of hymenopteran insects,play an important role in the biological control of pests.Based on this point,a general survey of wasps parasitizing L.trifoliata was carried out in Hainan Province from October to December 2021.A new species that has not been reported in China was identified by morphological identification,which belongs to the genus of Phaedrotoma(Hymenoptera:Braconidae),it was named as Phaedrotoma sp.2.Molecular identification based on the mitochondrial COI gene further confirmed the taxonomic status of the wasp,and the phylogenetic tree showed that it was clustered into the genus of Phaedrotoma.This study lays a foundation for the artificial breeding of L.trifoliata parasitoids in the future and contributes to the application of biological control of agricultural pests.
