Blueberry Gall Midge on Southern Highbush Blueberry in Florida
Oscar Liburd and Doug Phillips
Blueberry gall midge (Dasineura oxycoccana (Johnson)) is a small fly native to North America that feeds on blueberries and cranberries (Vaccinium spp.). It can be found throughout the United States, including in Florida, where its larvae feed on southern highbush blueberry (SHB) and rabbiteye floral and vegetative buds. Reports of blueberry gall midge damage on SHB in Florida have become more common in recent years. In some cases where there was severe feeding damage to floral buds, the midge significantly impacted yield.
