Honeybees pick up ‘astonishing’ number of pesticides via non-crop plants
Purdue researchers found that honeybees collect pollen from a wide range of plants, even in areas dominated by corn and soybeans. Christian Krupke, professor of entomology, and then-postdoctoral researcher Elizabeth Long collected pollen from Indiana honeybee hives at three sites over 16 weeks to learn which pollen sources honeybees use throughout the season and whether they are contaminated with pesticides. The pollen samples represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes, including neonicotinoids – common corn and soybean seed treatments that are toxic to bees.
