Two of the parasitic wasps, which previously reported as Apanteles spp. (Hymenoptera: Braconidae: Microgastrinae), can play important role in controlling Ectropis spp. during the larval stage in nature. In order to determine the species names and morphological differences of the two wasps, and to confirm whether these two species are common parasitic wasps of E. obliqua and E. grisescens, we identified the wasp specimens emerged from E. obliqua and E. grisescens that were collected from 22 locations in 8 provinces of China and reared in the laboratory, and compared the COI sequences of the voucher specimens with those of known species recorded in the BOLD database. The findings revealed that both parasitic wasps emerged from E. obliqua as well as E. grisescens during the larval stage. Based on morphological and molecular data, these two species of Apanteles spp. were identified as Protapanteles immunis (Haliday, 1834) and Parapanteles hyposidrae (Wilkinson, 1928). In conclusion, this study has confirmed the specific species names and morphological characteristics of the two wasps reported as Apanteles sp. in China more than 40 years ago, which are common larval parasitic wasps of E. obliqua and E. grisescens, and the P. immunis is recorded for the first time in China. These results provide a scientific basis for accurately identifying indigenous dominant parasitic wasps, which might help manage E. obliqua and E. grisescens. %U http://www.zgswfz.com.cn/EN/10.16409/j.cnki.2095-039x.2022.01.003
