Were ancient bees specialists, devoting their pollen-collecting attentions to very specific plant partners? Or were they generalists, buzzing around to collect pollen from a variety of flowers in their midst? Researchers who’ve studied Continue Reading »

Native Field-foraging Bees Exposed to Neonicotinoid Insecticides and Other Pesticides

Posted On: November 5, 2015

United States Geological Survey According to the first-ever study of pesticide residues on field-caught bees, native bees are exposed to neonicotinoid insecticides and other pesticides. This report was conducted by the U.S. Geological Survey and published in the journal Science of the Total Environment. This research focused on native bees, because there is limited information Continue Reading »

Urban Environments Boost Pathogen Pressure on Honey Bees

Posted On: November 4, 2015

North Carolina State University Researchers from North Carolina State University have found that urban environments increase pathogen abundance in honey bees (Apis mellifera) and reduce honey bee survival. The finding raises significant questions as urban areas continue to grow at the expense of rural environments, and urban beekeeping becomes more popular. “We wanted to determine Continue Reading »

Study Explores What We Know About How Neonicotinoids Affect Bees

Posted On: November 2, 2015

University of Guelph An international group of pollination experts – including a University of Guelph professor – has published a second summary in as many years on the scientific evidence about the effects of neonicotinoid pesticides on bees. The report was published this week in Proceedings of the Royal Society B. “The extent to which Continue Reading »

Study Finds Glyphosate and Acetamiprid to Have Relatively Low Toxicity for Honey Bees

Posted On: October 13, 2015

Entomological Society of America Researchers from the U.S. Department of Agriculture’s Agricultural Research Service (USDA-ARS) and Mississippi State University tested 42 commonly used pesticides in a realistic field setting in order to determine their toxicity levels. The results were published in the Journal of Economic Entomology. The researchers found that 26 pesticides, including many (but Continue Reading »

Threat Posed by ‘Pollen Thief’ Bees Uncovered

Posted On: October 12, 2015

This is a pollen thief bee in action. Credit: Dr Mario Vallejo-Marin A new University of Stirling study has uncovered the secrets of ‘pollen thief’ bees – which take pollen from flowers but fail to act as effective pollinators – and the threat they pose to certain plant species. Flowers often need pollinators, such as Continue Reading »

Study Shows Africanized Bees Continue to Spread in California

Posted On: September 14, 2015

University of California – San Diego A study conducted by biologists at UC San Diego has found that the Africanized honey bee–an aggressive hybrid of the European honey bee–is continuing to expand its range northward since its introduction into Southern California in 1994. The study, published in this week’s edition of the journal PLoS ONE, Continue Reading »

Parasitized Bees are Self-medicating in the Wild, Dartmouth-led Study Finds

Posted On: September 2, 2015

Dartmouth College A Dartmouth-led study finds that bumblebees infected with a common intestinal parasite are drawn to flowers whose nectar and pollen have a medicinal effect, suggesting that plant chemistry could help combat the decline of bee species. Credit: Leif Richardson HANOVER, N.H. – Bumblebees infected with a common intestinal parasite are drawn to flowers Continue Reading »
