Pesticides offer bees a risky allure

Tests show some pollinators can’t taste certain widely used pesticides that may cause them harm

Bees flit from flower to flower dining on nectar. Sometimes that nectar may contain traces of widely used pesticides. Yet the bees are unlikely to know which nectar is tainted. Indeed, they can’t taste these pesticides, a new study finds. However, the pesticides are similar to nicotine. This can encourage the bees to come back for more. And especially troubing: A second new study suggests the pesticides can harm some wild bees.

The pesticides are known as neonicotinoids (Nee-oh-NICK-uh-tin-oydz). Farmers use them to protect their crops from certain insects. The two new bee studies add to the controversy surrounding the use of these chemicals on corn and other crops.
