This study aims to construct essential information on the pests attacking Cnidium officinale Makino, which is one of the most important medicinal plants in Korea and neighboring countries. Based on the current survey, a total of 12 species were identified, including three above-ground pests attacking flowers, leaves, and stems, as well as ten soil pests attacking roots. In the vertical distribution of damaged roots, the dominant species is bulb mite (Rhizoglyphus robini) followed by onion maggot (Delia antiqua). Based on this study and the previous literature, the total number of species of pests reported to attack C. officinale is 36, including 3 on flowers, 16 on leaves, 6 on stems, and 11 on roots. We also investigated and compiled a list of natural enemies based on all available information and the current study, totaling 14 species. Parasitus sp., Macrocheles glaber, and Smicroplectrus sp. were identified as candidate natural enemies of root pests.

The family Glyphipterigidae comprises small-sized moths with a wingspan ranging from 8 to 14 mm. This family is mainly distributed in the Palaearctic and Oriental Regions. In Korea, five species of the genus Acrolepiopsis Gaedike, 1970 have been recorded. However, species-level identification within this genus is often challenging due to high morphological similarity amongst species. In this study, two new species of the genus Acrolepiopsis, A. quinquelobatae sp. nov. and A. koreana sp. nov., are described from Korea. Species delimitation is supported by COI gene analysis and morphological characteristics of genitalia, both of which reveal clear genetic divergence from other Acrolepiopsis species previously recorded in Korea. Photographs of adults and genitalia, along with information on host plants, are also provided.
