Popular Herbicide Weakens Bumblebees’ Colour Vision
Researchers at the Universities of Turku and Oulu, Finland, found out how Roundup, a herbicide containing glyphosate, affects the learning and memory of bumblebees. Already a small dose affected their ability to learn and memorise connections between colours and taste. The weakened fine colour vision can severely impair bumblebees’ foraging and nesting success.
