Blueberry Maggot – Rhagoletis mendax

adult fly - Agriculture and Agri-Food Canada

The blueberry maggot was first detected in Maine and New Hampshire in 1914. Since its first detection it has become a important pest of commercially grown low bush and high bush blueberries in the Canadian Maritime Provinces.

The primary host of the blueberry maggot is blueberry, both high bush (Vaccinium corymbosum) and low bush (V. angustifolium, V. myrtilloides and V. vacillans). Other suitable hosts include Hillside blueberry (V. pallidum), Deerberry (V. stamineum) and Huckleberry (Gaylussacia spp).
