Gene regulation underlies the evolution of social complexity in bees

Posted by External 12 days ago General — Explaining the evolution of insect society, with sterile society members displaying extreme levels of altruism, has long been a major scientific challenge, dating back to Charles Darwin's day. A new genomic study of 10 species of bees representing a spectrum of social living -- from solitary bees to those in complex, highly social colonies -- offers new insights into the genetic changes that acco Read More

Why Bees Can't Avoid Pesticides

Posted by External 29 days ago General — Pesticides such as as neonicotinoids are already under close scrutiny because research appears to show that, certainly for honey bees at least, they may interrupt the insect’s normal behaviors and they are suspected to play a part in colony collapse disorder.

Poor diet may contribute to the decline in British bees

Posted by External 34 days ago General — The changing British landscape could be contributing to the decline in its bee populations, according research. Analysis of 35 hives in 20 sites in North West England found that honeybees living near areas of extensive farmland were surviving on a lower protein diet than those in hives near natural grasslands and woodlands.

Pesticide harms wild bees, unique field study shows

Posted by External 34 days ago General — For the first time, a research project has investigated how a neonicotinoid pesticide, clothianidin, affects both honeybees and wild bees in an agricultural landscape. The study shows that honeybees can cope with exposure to the pesticide, but that it has a strong negative impact on wild bees. Read More

Manganese speeds up honey bees

Posted by External 59 days ago General — The industrial metal manganese, once scarce, is now ubiquitous in our environment. New work suggests that it addles honey bees, which often act as sentinel species for environmental contaminants, even at levels considered safe for humans. Read More
