Vomiting bumblebees show that sweeter is not necessarily better

Animal pollinators support the production of three-quarters of the world’s food crops, and many flowers produce nectar to reward the pollinators. A new study using bumblebees has found that the sweetest nectar is not necessarily the best: too much sugar slows down the bees. The results will inform breeding efforts to make crops more attractive […]

Smart single mother bees learn from their neighbours

Solitary female bees inspect other nests for signs of danger before making decisions on where to build their own, a new London-based study suggests. The study, led by researchers at Queen Mary University of London, found the clever bees looked for signs of parasite infection in other species‘ nests and used this information to select a […]

Researchers find bee species where males perform babysitting duties

  A team of researchers with Charles University and the Czech Academy of Science has discovered a species of bee where males guard a nest while females are off gathering food for their young. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of Ceratina nigrolabiata and what […]

Bacteria engineered to protect bees from pests and pathogens

  Scientists from The University of Texas at Austin report in the journal Science that they have developed a new strategy to protect honey bees from a deadly trend known as colony collapse: genetically engineered strains of bacteria. An increasing number of honey bee colonies in the U.S. have seen the dwindling of their adult bees. According […]

Bumblebees are going extinct in a time of ‘climate chaos’

Loss of the vital pollinators, due in part to temperature extremes and fluctuations, could have dire consequences for ecosystems and agriculture.   BUMBLEBEES, AMONG THE most important pollinators, are in trouble. Fuzzy and buzzy, they excel at spreading pollen and fertilizing many types of wild flora, as well as crucial agricultural crops like tomatoes, blueberries, and […]

When stuck in water, bees create a wave and hydrofoil atop it, study finds

  Close study of bees in water revealed that they generate asymmetric waves, which they use to propel themselves forward. Credit: Chris Roh and Mory Gharib / Caltech Walking on Caltech’s campus, research engineer Chris Roh (MS ’13, Ph.D. ’17) happened to see a bee stuck in the water of Millikan Pond. Although it was […]

How bees live with bacteria

A solitary bee leaves an artificial nest. The individual breeding chambers are separated and each contains only one larva. This prevents direct contact with sisters or mothers. Credit: Alexander Keller / University of Wuerzburg More than 90 percent of all bee species are not organized in colonies, but fight their way through life alone. They […]
