Introduced Honey Bees Could Cause Plant Extinction

Honey bees out-compete local pollinators, which play vital specialist role in plant pollination New research indicates that introduced 'alien' honey bees are competing for resources with native bees and threatening the survival of plants that rely on interactions with specific pollinators. The study, published in the journal Diversity and Distributions, was led by Dr. Olivia Norfolk of Anglia Ruskin University, who carried …

Agricultural Fungicide Attracts Honey Bees, Study Finds

When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports. The puzzling finding comes on the heels of other studies linking fungicides to declines in honey bee and wild bee populations. One recent study, for example, found parallels between the use of chlorothalonil …

Nectar-Living Microbes Influence Pollinator’s Foraging Preference

Hear that honey bee buzzing toward a flower? It's not just the nectar that she's scented. Nectar-living microbes release scents or volatile compounds, too, and can influence a pollinator's foraging preference, according to newly published research led by UC Davis community ecologist Rachel Vannette. The groundbreaking research, published in the current edition of New Phytologist journal, shows that nectar-inhabiting species of bacteria and fungi …

Clemson, UNCG Researchers Test Honey Bee
Response to Eclipse Totality

By T. DeLene Beeland CLEMSON, South Carolina — About two miles from the Clemson University campus, where 50,000 people gathered to gaze skyward during the Aug. 21 total solar eclipse, bee researcher Jennifer Tsuruda kept her eyes focused earthward to see how honey bees behaved when nighttime darkness momentarily interrupted afternoon sun. The lives of honey bees are intertwined with the sun. They …

Pollen Stays on Bee Bodies Right Where Flowers
Need it For Pollination

Ungroomed sites correspond with flower pollen-sacs and stigmas PLOS After grooming, bees still have pollen on body parts that match the position of flower pollen-sacs and stigmas, according to a study published September 6, 2017 in the open-access journal PLOS ONE by Petra Wester from Heinrich-Heine-University, Germany, and colleagues. Flowers depend on pollen for pollination, and flower-visiting bees collect large quantities of pollen …

Study Finds Parallels Between Unresponsive Honey Bees, Human Autism

University of Illinois at Urbana-Champaign CHAMPAIGN, Ill. -- Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found. The findings, reported in …

Climate Change Threatens Domestic Bee Species

University of Würzburg There are around 550 different bee species in Germany. Most of them are solitary bees. They don't live in large beehives like the honeybee, but each female bee often builds multiple nests and feeds her offspring alone. Solitary bees use their short lifespan of a few weeks exclusively to reproduce and to provide food for their brood to …
