Honeybee larvae develop into workers but not queens, in part, because their diet of beebread/pollen is enriched in plant miRNAs. While miRNAs are generally negative regulators of gene expression in eukaryotes, they also negatively regulate larval development when honeybee larvae consume beebread/pollen and take up plant miRNAs. Xi Chen and Chen-Yu Zhang’s group in Nanjing … More Cross-kingdom regulation of honeybee caste development by dietary plant miRNAs
Set your meetings, phone calls and emails aside, at least for the next several minutes. That’s because today you’re a bee. It’s time to leave your hive, or your underground burrow, and forage for pollen. Pollen is the stuff that flowers use to reproduce. But it’s also essential grub for you, other bees in your … More You’re a Bee. This Is What It Feels Like.
Bumble bees create foraging routes by using their experience to select nectar-rich, high-rewarding flowers. A study now suggests that bees actually forage more efficiently when flower sizes are large rather than small. This indicates that for these insect pollinators foraging quickly is more efficient than foraging accurately. Bumble bees create foraging routes by using their … More Bumble bees make a beeline for larger flowers
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 … More Climate change threatens domestic bee species
A researcher has devised a new bee monitoring system to better understand what more than 20,000 honeybees housed in hives in a local field are ‘saying’ to each other — looking for clues about their health. Simon Fraser University graduate student Oldooz Pooyanfar is monitoring what more than 20,000 honeybees housed in hives in a … More Technology tracks ‘bee talk’ to help improve honey bee health
The worst beekeeping mistakes come from putting off what you should have done yesterday. Somehow, problems inside a bee hive don’t get better by themselves. I keep thinking they will, but they don’t. I normally remove my honey supers by June 30 because that is the start of our nectar dearth. Once the supers come off, the … More Incredibly stupid things a beekeeper can do
Seemingly indestructible Varroa mites have decimated honeybee populations and are a primary cause of colony collapse disorder, or CCD. Scientists have found genetic holes in the pests’ armor that could potentially reduce or eliminate the marauding invaders. The team’s results have identified four genes critical for survival and two that directly affect reproduction. Michigan State … More Varroa mites — bees’ archenemies — have genetic holes in their armor
