First US wild bee map reveals 139 ‘trouble zone’ counties The first-ever study to map U.S. wild bees suggests they are disappearing in the country’s most important farmlands — from California’s Central Valley to the Midwest’s corn belt and the Mississippi River valley. A new study of wild bees identifies 139 counties in key agricultural … More Bee decline threatens US crop production
New research from a team of Florida State University scientists and their collaborators is helping to explain the link between a changing global climate and a dramatic decline in bumble bee populations worldwide. This is Bombus bifarius, one of the three species of bumble bee studied by the Ogilvie and her team. Credit: Jane Ogilvie … More A stinging report: Climate change a major threat to bumble bees
he honey bee gut is colonized by specialized bacteria that help digest components of the floral pollen diet and produce molecules that likely promote bee health. In a study publishing 12 December in the open access journal PLOS Biology, a group of researchers led by Philipp Engel at the University of Lausanne and ETH Zürich, Switzerland, … More How honey bee gut bacteria help to digest their pollen-rich diet
The tiny pollinators are useful sentinels of what’s going on in an ecosystem, and might just be environmentalists’ best asset.

Amini) By Rachel Kaufman It’s a sunny day, and Vancouver’s Downtown Eastside neighborhood is buzzing. Commuters are commuting, delivery trucks are delivering, … More Can Honeybees Monitor Pollution?
Source: National Centre for Biological SciencesSummary:Although at least 75 percent of our crop species depend on animal pollinators, little is known about their flower preferences. As global insect populations decline, it is of utmost importance for us to understand what factors attract wild pollinators to flowers, and how these preferences differ in the face of … More Laws of attraction: Pollinators use multiple cues to identify flowers across continents
Wednesday November 15, 2017 saw the official launch of one of the most ambitious conservation programmes in England – Back from the Brink. Project partners, volunteers and other distinguished guests met at Windsor Great Park to celebrate the launch of the programme, which aims to bring 20 species back from the brink of extinction. This is … More A Grassroots Organization Launch of ‘Back from the Brink’
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
