New buzz on bees and crops: New answers, more questions, ‘good potential’ for joint research

How do field crops affect honey bees? And honey bees affect field crops? Recent research by CFAES scientists has found new answers but points to more questions.

Reed Johnson and colleagues have discovered, for example, that honey bees, while foraging, can pick up dust from insecticide-coated corn seeds that has chipped off, drifted away, and landed on trees and flowers. The bees can also pick up the dust when they travel across fields during corn-planting season. Either way, the bees can carry that dust to their hives, where it carries a risk to young bees.

In another study, Johnson and a colleague found that 47 percent of the Ohio honey they tested had pollen from soybeans present in it.

“We know that bees in Ohio are visiting soybeans and that soybeans may be contributing to honey production,” said Johnson, who’s an assistant professor in the Department of Entomology at OARDC in Wooster. “Also, there’s some evidence that pollination by bees can help increase soybean yield.”

Looking ahead, he said, there’s “good potential for people to work together on this line of research. It’s a valuable opportunity to have these two sides of agriculture — field crops and beekeeping — come together and explore mutual benefits.”

Honey bees needed for billions in food

  • Honeybees and other pollinators pollinate about a third of the crops grown in the U.S.
  • Together those crops have a value of more than $14 billion a year.
  • Corn, however, is pollinated by the wind, while soybeans are mostly self-pollinated.
