Dasineura jujubifolia was introduced into Korea for the first time in 2011, a gall midge feeding on jujube (Ziziphus jujuba Miller (Rhamnaceae)). Since then the jujube gall midge become a serious insect pest of Jujube in Korea. In this year, we surveyed regulated and alien insect pests by collecting damaged leaf samples from different regions in Korea. Jujube gall midge and its life stage were identified by morphological and genetic characteristics. For molecular identification, we analyzed the cytochrome c oxidase subunit I (COI) sequences of pest. In this study, we report the morphological description and genetic information of D. jujubifolia.
