What to know about How a common herbicide affects honeybee brains and behavior

A study from Virginia Tech found that exposure to glyphosate, a common herbicide, reduces honeybee foraging behavior and alters brain chemistry, potentially threatening hive stability. The research highlights the need for further understanding and regulation of glyphosate use to protect pollinators.

Why it matters

Honeybees are attracted to these locations and play a critical role in their success.

Common ground

So what happens when foraging bees pick up a dose of weedkiller?
