Detecting poisons in nectar is an odour-ous task for honeybees

...e, texture or scent with food. The newly-sequenced honeybee genome has revealed that honeybees do not have as many genes for taste receptors as other animals of a similar size, such as flies and mosquitoes. This prompted scientists to think that perhaps honeybees had a reduced need to detect and learn about ...

Seeley then sprayed the brood colonies of the resulting 49 colonies (24 from "multiple-mate" queens and 25 from singly mated queens) with water tainted with spores of ...

ASU researchers find link between social behavior, maternal traits in bees

... Amdam met professor Robert Page, who was breeding honeybee strains distinguished by whether the worker bees were more likely to collect pollen or nectar. Besides their differing collecting habits, the strains possessed various other physiological and sense-related traits, but researchers did not understand h...

Waggle dance controversy resolved by radar records of bee flight paths

...destinations they have never visited before. If a honeybee worker discovers a good feeding site it is believed that she informs her nest mates through a dance that describes the distance and direction of the feeding site. This 'dance language' was first described by Karl von Frisch in the 1960s but his exper...
