“Our results suggest that current levels of pesticide exposure could be significantly affecting how bees are interacting with wild plants, and impairing the crucial pollination services they provide that support healthy ecosystem function,” he said.
In other words, if herbicides hinder bumblebees’ ability to learn and adapt, then wild bees could become increasingly sensitive to changes in the environment. According to a separate review, an estimated 57 different herbicides are poisoning European honey bees, which is contributing to the rapidly declining bee population worldwide.
