Biofuel crop diversity adds value, Michigan State researchers say

EAST LANSING, Mich. — Diverse biofuel plantings such as native prairie attract more beneficial insects than do single crops such as corn, Michigan State University scientists find. Therefore, biofuel policies should take such added value into account, they urge, based on their pioneering studies of beneficial insects in biofuel crops.

Lady beetles, bees and other beneficial insects provide numerous ecosystem services, including controlling pests and pollinating crops. Earlier research by MSU scientists estimated that such insects in soybeans provide about $240 million worth of biological pest control per year in the U.S.
"We found that the diversity of the plants has a direct effect on the number and diversity of beneficial insects," said Doug Landis, MSU professor of entomology and co-author of the study, to be published in a special issue of the journal BioEnergy Research. "As policymakers consider which biofuel crops to support with incentives, we want to make sure they know about all the benefits provided by a range of crops. Some of these benefits, such as greenhouse gas benefits, pest suppression and pollination, are not currently being counted."
