Two pesticides target same learning centre of bee brain

Research shows combined pesticides impact on bee brain function

Bees become slower to learn and forget floral scents

Two new studies have highlighted a negative impact on bees' ability to learn following exposure to a combination of pesticides commonly used in agriculture. The researchers found that the pesticides, used in the research at levels shown to occur in the wild, could interfere with the learning circuits in the bee's brain. They also found that bees exposed to combined pesticides were slower to learn or completely forgot important associations between floral scent and food rewards.
