Earlier this spring, instead of hiring commercial honeybee keepers to bring in their hives to apple orchards, Cornell decided to try relying solely on wild bee species for pollination of the blossoms at their Ithaca site. Based on research from the university’s entomology department, the Cornell Orchards knew it had a robust population comprised of twenty-six different wild bee species among the Ithaca apple trees. They counted on this local bee life to do all the pollinating work that the imported European honeybees would have done, and by the end of May it was clear that a full crop’s worth of flowers had been pollinated! We’ve featured plenty of stories about the deeply troubling colony collapse disorder in Apis mellifera and are always eager to emphasize the importance of pollination, so it may seem strange to celebrate the non-use of European honeybees in this case, but the main point here is that the value of wild native bee species should not be forgotten! If commercial honeybees continue to struggle, alternative methods of pollination will be necessary, and fostering local biodiversity is a great way to compensate for that potential eventuality.
As a fun coincidence, I heard about this story because the lead researcher in the wild bee population was my entomology professor sophomore year. You can read more about Professor Bryan Danforth’s role and the Cornell Orchards decision in the piece for the Cornell Chronicle below, by John Carberry:
As the state’s land-grant institution, Cornell University was born to explore science for the public good – a mission that can sometimes require a leap of faith.
Just such a leap is paying off now at Cornell Orchards in Ithaca, as researchers and managers from the Horticulture Section of the School of Integrative Plant Science and the Department of Entomology celebrate a solid spring pollination season for the site’s apple trees. While crisp apples and fresh cider Continue reading →
