Honey bee teenagers speed up the ageing process of their elders
Dec 06, 2016
In honey bee colonies, a single queen is laying eggs from which thousands of worker bees are born. At a young age, workers care for the brood, then build and defend the nest and eventually, towards the end of their lives, ...
Concern over parasites affecting honey bees
Nov 15, 2016
Scientists from The University of Western Australia's Centre for Integrative Bee Research (CIBER) tagged 200 honey bee workers to find out how a highly-contagious fungal parasite (Nosema apis) impacts their ability to pollinate ...
No single protein determines queen development in honeybees
Oct 12, 2016
The proteins in the larval food of honeybees are not specific determinators to make the larvae grow into queens—that includes the protein royalactin, which had been previously claimed to be the 'queen determinator' in a ...
Researchers identify how queen bees repress workers' fertility
Aug 03, 2016
Researchers from New Zealand's University of Otago have discovered the molecular mechanism by which queen honeybees carefully control worker bees' fertility.
'Genetic super switch' separates insect boys from girls and queens from the plebs
Apr 12, 2016
Social insects such as ants, bees and wasps appear to be blessed with a genetic 'super switch' that designates both gender and their status as either a queen or worker, scientists have discovered.
Insecticide increases effect of varroa mite
Feb 04, 2016
Honeybees infected with the Varroa destructor mite have less stamina than those which have been effectively treated against the parasite. Additional exposure to the insecticide Imidacloprid further increases the harmful effect ...
How queen bees control the princesses
Jan 28, 2016
Queen bees and ants emit a chemical that alters the DNA of their daughters and keeps them as sterile and industrious workers, scientists have found.
Conflict among honey bee genes supports theory of altruism
Jan 11, 2016
Using modern genetic approaches, a team of researchers has provided strong support for the long-standing, but hotly debated, evolutionary theory of kin selection, which suggests that altruistic behavior occurs as a way to ...
Urban hives can help safeguard the future of food, says a scientist and beekeeper
Nov 24, 2015
If you eat food, then you like bees. It's estimated that one-third of the typical American diet depends on pollination by bees, and absent such pollination, nearly 100 fruit and vegetable crops would be wiped out. We wouldn't ...
Male bees have more than a one-track mind
Nov 12, 2015
Male bumblebees are just as smart as female worker bees despite their dim-witted reputation, according to new research from Queen Mary University of London (QMUL).
