Can behavior be controlled by genes? The case of honeybee work assignments
What worker bees do depends on how old they are. A worker a few days old will become a nurse bee that devotes herself to feeding larvae (brood), secreting beeswax to seal the cells that contain brood and attending ...
Promiscuous queen bees maintain genetic diversity
By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy.
Use of imidacloprid - common pesticide - linked to bee colony collapse
The likely culprit in sharp worldwide declines in honeybee colonies since 2006 is imidacloprid, one of the most widely used pesticides, according to a new study from Harvard School of Public Health (HSPH).
Plants mimic scent of pollinating beetles
The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has ...
Bees 'self-medicate' when infected with some pathogens
Research from North Carolina State University shows that honey bees "self-medicate" when their colony is infected with a harmful fungus, bringing in increased amounts of antifungal plant resins to ward off ...
Studies say commonly used pesticide may harm bees
(AP) -- A common class of pesticide is causing problems for honeybees and bumblebees, important species already in trouble, two studies suggest.
Study shows insect mimic abilities related to size
Pesticides not sole cause of declining bee numbers
(PhysOrg.com) -- Despite a growing worldwide clamor to ban pesticides linked to honey bee deaths, multiple factors contribute to the declining honey bee population, not just one class of insecticides, says Extension Apiculturist ...
Researchers attempt to solve problems of antibiotic resistance and bee deaths in one
The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans.
Increased honey bee diversity means fewer pathogens, more helpful bacteria
A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more ...
Increasing genetic diversity of honey bees needed
(PhysOrg.com) -- Increasing the overall genetic diversity of honey bees will lead to healthier and hardier bees that can better fight off parasites, pathogens and pests, says bee breeder-geneticist Susan Cobey ...
Honey bees study finds that insects have personality too
A new study in Science suggests that thrill-seeking is not limited to humans and other vertebrates. Some honey bees, too, are more likely than others to seek adventure. The brains of these novelty-seeking bees e ...
Warm winter may bring pest-filled spring
(AP) -- The mild winter that has given many Northern farmers a break from shoveling and a welcome chance to catch up on maintenance could lead to a tough spring as many pests that would normally freeze have not.
Heavy metal pollution causes severe declines in wild bees
Wild bees are important pollinators and numerous studies dealing with pollination of wild plants and crops underline their vital role in ecosystems functioning. While honey bees can be easily transported to ...
