Ensuring pumpkin pollination

Pumpkin is entirely dependent on insects for pollination.  We first review the flower structure and the pollen and nectar rewards pumpkins offers to achieve pollination, and what that means for fruit set.  We overview the range of bee species that interact with these flowers in commercial settings, and then focus on the three dominant species for providing pollination: bumble bees, squash bees, and honey bees.  We review their biology and ecology, and detail visitation rates and population levels observed in commercial settings.  We discuss how management - rotation, tillage, IPM practices,  floral provisioning with perennial meadows or cover crops, rental of managed honey and bumble bees, and irrigation - at the farm and landscape scale can help conserve both wild and managed bees that provide the ecosystem service of pollination to pumpkins.
