Abstract: 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.

Key words: Liriomyza trifoliata, parasitic wasp, Phaedrotoma
