The blueberry gall midge, Dasineura oxycoccana (Johnson)(Diptera: Cecidomyiidae), has known as a key pest of blueberries in the southeastern United States, Europe and Canada. It can cause considerable damage to developing blueberry flower buds and also injure vegetative growth by distorting and blackening shoot tips. Similar symptoms of damage, which mighty be caused by D. oxycoccana, have been investigated on blueberry plants(damage rate: 20~80% of total shoot tips), Vaccinium spp., in Hwaseong-si of Gyounggi-do in 2010. And, followed by an investigation on the occurrences of D. oxycoccana and its damages in 2010~2012. We emphasize caution concerning the possibilities that D. oxycoccana could infest flower buds and shoot on blueberries and developed monitoring methods and environment-friendly management strategies for D. oxycoccana on buleberry.
