Blueberry gall midge, Dasineura oxycoccana

The blueberry gall midge is native to North America and invasive in Asia and Europe. It is a highly specialised pest of Vaccinium crops, such as blueberries and cranberries. The pest targets newly developed buds, stunting growth and reducing crop yield, with severe attacks causing complete crop failure. Hidden within the buds, larvae are difficult to control using pesticides. Generations can reach 5-6 per year. As part of an IPM programme, monitor adults using Delta traps with the highly senstive Dasineura oxycoccana pheromone lures and Optiroll Super Plus (white-midge) for mass trapping.
