Study Shows Fruit-Crop Yields Declining from Lack of Pollinators

Research led by Rutgers and published in Proceedings of the Royal Society B: Biological Sciences shows that crop yields for apples, cherries, and blueberries across the United States are being reduced by a lack of pollinators. Scientists collected data on insect pollination of crop flowers and yield at 131 farms across the United States and in Canada. Apples, sweet cherries, tart cherries, and blueberries showed evidence of being limited by pollination, indicating that yields are currently lower than they would be with full pollination. The findings suggest that adopting practices that conserve or augment wild bees, such as enhancing wildflowers and using managed pollinators other than honey bees, is likely to boost yields.
