Diesel exhaust stops honeybees from finding the flowers they want to forage

Exposure to common air pollutants found in diesel exhaust pollution can affect the ability of honeybees to recognise floral odours, new University of Southampton research shows.

Honeybees use floral odours to help locate, identify and recognise the flowers from which they forage.

The Southampton team, led by Dr Tracey Newman and Professor Guy Poppy, found that diesel exhaust fumes change the profile of flora odour. They say that these changes may affect honeybees' foraging efficiency and, ultimately, could affect pollination and thus global food security.
