Honey bees are hardwired to efficiently search the landscape enabling them to continue working for the greater good of their hives even when they are sick, according to new research co-authored by Queen Mary University of London (QMUL).

Radar technology has been used to show for the first time that bees remain nimble and able to search and respond to their environment even when they have infections or viruses.

Honey bees tirelessly commute between rewarding flower patches and their hive, often hundreds or even thousands of metres apart. Their remarkable navigational skills rely on distinct landmarks, such as trees or houses, which they very efficiently find and memorize on orientation flights.

Experts fitted a transponder, a tiny dipole aerial much lighter than the nectar or pollen normally carried by the bee, to the thorax of the bee. Tracking each bee individually they would pick up a radar signal form the transponder showing where and how it was flying.
