Fruit set, berry size, and berry weight were assessed for pollination by the solitary beeOsmia lignaria(Say) in caged rabbiteye blueberries (Vaccinium asheiReade, Ericales : Ericaceae), and compared to that of uncaged rabbiteye blueberries which were pollinated largely by honey bees (Apis melliferaL).O. linariaproduced berries that were 1.6mm larger in diameter and 0.45g heavier than uncaged blueberries. Fruit set was 40% higher in uncaged blueberries. This suggests thatOsmiabees can produce larger and heavier berry fruit, butO. lignariamay be less efficient at blueberry pollination as compared toA. melliferaunder field cage conditions. |
