Colony Size Drives Honey Bees’ Overwinter Survival
Research in Pennsylvania shows that overall colony weight and the number of worker bees to be the leading factors in determining overwintering survival of honey bee (Apis mellifera) colonies. For colonies in which the combined weight of adult bees, brood, and food stores exceeded 30 kilograms, overwinter survival rates were about 94 percent.
Why Pesticides Pose Different Kinds of Risk to Non-Honey Bees
A new collection of reports in Environmental Entomology highlights the need for pesticide risk assessments that account for the differing qualities and behaviors between honey bees and bumble bees, solitary bees, and stingless bees.
No Buzz, No Problem: Study Shows How Honey Bees Pollinate Blueberries
Honey bees are incapable of buzz pollination, but they can (and do) perform pollination duties in highbush blueberry. A new study shows that, while honey bees rarely collect blueberry pollen in the pollen baskets on their hind legs, they frequently contact it with other body parts and transfer it to other flowers.
Propolis Power-Up: How Beekeepers Can Encourage Resin Deposits for Better Hive Health
When honey bees produce more propolis, a waxy resin they use for sealing up their hives, overall health benefits to the colony ensue. A new study tests a few simple methods beekeepers can use to encourage more propolis production in their hives.
Bees Stopped Buzzing During the 2017 Total Solar Eclipse
A study conducted during the 2017 total solar eclipse in North America found that bees remained active during partial-eclipse phases, but they essentially ceased flying during totality.
For Good of the Colony, Sick Honey Bee Brood Sounds the Alarm
Honey bees detect and remove brood afflicted with parasites or pathogens. A new study shows that part of this "hygienic behavior" relies on chemical signals emitted by unhealthy brood, and brood coming from colonies bred to be more hygienic are more effective in signaling for their own removal.
Why Smoking Soothes the Stressed-Out Bee Hive
A new study that explores the effect of smoke on honey bee (Apis mellifera) behavior finds that it reduces the instance of bees releasing a venom droplet in their signaling of danger to other bees, which researchers speculate may thereby reduce the amount of alarm pheromone released.
Funny Honey at the Zoo Reveals Bees’ Foraging on Sugar Baits
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
More Research Needed to Better Balance Honey Bees and Native Bees
A review of existing research on floral resource competition between managed honey bees and wild bees shows gaps in our knowledge about such interactions and calls for further research to better inform decisions on honey bee management and pollinator protection.
Beyond the Honey Bee: How Pesticides Affect Solitary, Cavity-Nesting Bees
Solitary bees face different—and less well-understood—challenges from pesticide exposure than their colony-dwelling honey bee cousins. A pair of entomologists encourage colleagues to dedicate more research to these important pollinators.
A Potential New Tool in the Battle Against a Bee-Killing Bacteria
American foulbrood disease is caused by a difficult-to-control and highly destructive bacterium. New research may have found a way to prevent infections of honey bees
Insect Astronauts: Eclipse Watchers Learn About Entomology in Orbit
Insects studied in experiments in outer space were featured at an entomology booth at an Eclipse Watching Event hosted by the Department of Entomology at a University of Illinois at Urbana-Champaign
The Microscopic Spines That Many Bee Species Use to Hatch
Perhaps you’ve seen the 2015 video from photographer Anand Varma (and shared again last week via National Geographic), a time-lapse of bee larvae hatching and growing in their cells: Watch: […]
How the Varroa Mite Co-Opts Honey Bee Behaviors to Its Own Advantage
As the managed honey bee industry continues to grapple with significant annual colony losses, the Varroa destructor mite is emerging as the leading culprit. And, it turns out, the very […]
Get to Know Tropilaelaps Mites, Another Serious Parasite of Honey Bees
By Josh Lancette The plight of honey bees is well documented, as is the cause of much of their grief: parasitic mites. Varroa destructor gets the largest amount of attention […]
Mite-Resistant Russian Honey Bees Might Not Prevent Varroa Infestations
By Meredith Swett Walker Imagine a parasite about the size of a grapefruit, and it’s latched onto your back where you just can’t reach it. Now imagine that parasite is […]
