Honey bees remain the pollinator of choice for watermelon, readily providing the large numbers of visits required to set high quality fruit. In larger fields at least, addition of honey bees should be added to improve pollination at a rate of 1-2.5 strong colonies per hectare. Shade and water should be provided for the bees on hot days. Managed bumble bees and the hoary squash bee (Peponapis pruinosa) have also been shown to be highly effective pollinators of watermelon. Further investigation of their effectiveness in commercial watermelon production, together with that of other wild solitary bees, is warranted.
