A New Sawfly Pest, Monocellicampapruni Wei (Hymenoptera, Tenthredinidae) Attacking Fruitlets of Japanese Plum in South Korea

摘要

A larval attack leading to severe loss to fruit production of Japanese plum (Prunus salicina Lindl.) was reported in the orchards in Gwangyang, Jeonnam province, South Korea during the spring seasons of 2018 and 2019. As the result of investigation, the damage was identified to be caused by Monocellicampa pruni Wei of the family Tenthredinidae. In this study, we present the first report of this pest in Korea and describe the damage caused by the larvae as well as taxonomic information by illustratingthe characteristics of male genitalia.
