New evidence from Japan's Lake Shinji suggests that the widely used family of pesticides called neonicotinoids, already controversial for harming pollinators, could pose risks to fish as well.
Studies are revealing new, unintended threats that neonicotinoid pesticides pose to insects. The chemicals, widely used by farmers, are difficult to control because they persist in the environment.
Bees exposed to a type of insecticides called neonicotinoids dramatically changed their behavior — becoming sluggish, antisocial and spending less time caring for the colony's young, researchers say.
A new study is adding to evidence that a popular class of pesticides can harm wild bees, like bumblebees.
A huge new study conducted in 33 sites across Europe finds that seeds coated with neonicotinoid pesticides harm bees living nearby. The damage, though, depends on local conditions.
Two scientists agree that pesticide-laden dust from planting equipment kills bees. But they're proposing different solutions, because they disagree about whether the pesticides are useful to farmers.
