Changes in land use negatively affect bee species richness and diversity, and cause major shifts in species composition, reports a recent study of native wild bees, conducted at the Sierra de Quila Flora and Fauna Protection Area and its influence zone in Mexico. Having registered a total of 14,054 individual bees representing 160 species, 52 … More Bee diversity and richness decline as anthropogenic activity increases, scientists confirm
Scientists from the University of Würzburg have investigated the impact of a new pesticide on the honeybee. In high doses, it has a negative impact on the insects’ taste and cognition ability. In February 2018, the European Food Safety Authority (EFSA) confirmed that the pesticide group of neonicotinoids is harmful to bees. A novel pesticide … More Pesticides give bees a hard time
Coles and Woolworths are abandoning an insecticide product which contains a controversial ingredient that has been linked to harming bee populations essential for pollination, The New Daily can reveal. More than 30,000 Australians have signed a petition, launched by global consumer group SumOfUs, calling on Australian retailers to stop selling insecticides containing neonicotinoids, including Yates Confidor which has been … More Woolworths and Coles cave in to pressure to abandon product accused of killing bees
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
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
