The survival of wild bees is of concern for natural and agricultural ecosystems, since crop yields may be negatively affected by insufficient native pollinators. Bee diversity and abundance were assessed in commercial blueberry fields and cranberry bogs in the Fraser Valley of British Columbia, Canada during crop bloom to assess populations of managed honey bees and wild bumble and other bees. Percent crop yield, average berry weight and number of mature seeds were assessed with respect to bee populations.


Species 1: Hymenoptera Apidae Bombus sp (Bumble Bee)
Species 2: Hymenoptera Andrenidae Andrena sp
Species 3: Hymenoptera Apidae Apis mellifera (honey bee)
Keywords: Berry agriculture, Crop yield
