Lowbush blueberry (syn. ‘‘wild blueberry’’), Vaccinium angustifolium Aiton (Ericaceae), is a native plant of northeastern North America. Over the past 100 yr, lowbush blueberry has become a major horticultural crop with thousands of hectares of intensively managed wild stands in production in the Atlantic provinces, Quebec, and the state of Maine (Kinsman 1986, 1996). Lowbush and highbush species of blueberries constitute approximately 50% of Canada’s land area in fruit and nut production, and blueberries are now the most important horticultural crop in the country in terms of farmed area and value (Robichaud 2006) The importance of insect-mediated pollination for successful lowbush blueberry production has long been appreciated.
