Honey bees show more resistance to pesticides if they eat a natural diet of pollen than artificial diets such as soy protein, say researchers at Penn State University.
Some 23,300 bee keepers nationwide would be contacted about honeybee mortality under a pair of surveys proposed by the Agriculture Department.
Landowners in five states in the upper Midwest are eligible for $8 million in payments if they establish new habitat for honey bees on land enrolled in the Conservation Reserve, says USDA.
