Effects of insecticides on the alfalfa leaf-cutting bee
Many agricultural crops are dependent on bee pollination for proper growth. The alfalfa leaf-cutting bee is an important pollinator of blueberries in Atlantic Canada. The insecticide flubendiamide appears to be non-toxic to both immature and adult alfalfa leaf-cutting bees. The insecticides phosmet, deltamethrin, spinosad, and spinetoram may have negative effects on leaf-cutting bees and therefore on crop pollination.
