The cultivation of wild lowbush blueberry (LB) (Vaccinium angustifolium Aiton; V. myrtilloides Michx) is of significant economic importance in Quebec, Canada, with substantial reliance on insect pollination for fruit set and yield. While both honey bees (Apis mellifera) and bumble bees (Bombus impatiens Cresson) are crucial for LB pollination, the optimal stocking density of these pollinators in LB fields remains unclear, particularly when used simultaneously. This study aims to address this gap by conducting a comprehensive investigation over four growing seasons to determine the ideal hive densities of honey and bumble bees for LB production in Quebec. Additionally, the project will develop a management tool to monitor pollination strength and need and create an agro-economic model to support LB growers in optimizing pollination strategies. Methodologies include field experiments testing various pollination stocking densities, high-definition time-lapse camera monitoring of foraging activities, and developing a predictive model integrating agronomic and economic key variables. Anticipated outcomes include increased crop yields and incomes for LB growers and improved pollination advisory services for industry partners. The research also holds broader implications for sustainable agriculture in Canada, positioning the country as a leader in crop pollination and enhancing its competitiveness in international markets.
