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.

How Bees Naturally Vaccinate Their Babies

Posted On: July 31, 2015

Researchers discover process bees use to protect their offspring Arizona State University With the discovery of how bees naturally vaccinate their babies, researchers can now develop the first vaccine for insects. This vaccine could be used to fight serious diseases¬† that decimate beehives. This is an important development for food production. Credit: Christofer Bang   Continue Reading »

Pesticides Found in Most Pollen Collected from Foraging Bees in Massachusetts

Posted On: July 24, 2015

Boston, MA — More than 70% of pollen and honey samples collected from foraging bees in Massachusetts contain at least one neonicotinoid, a class of pesticide that has been implicated in Colony Collapse Disorder (CCD), in which adult bees abandon their hives during winter, according to a new study from Harvard T.H. Chan School of Continue Reading »

Tagged Bees Causing a Buzz in Disease Research

Posted On: July 15, 2015

James Cook University James Cook University researchers are creating a buzz in bee research, gluing tiny transmitters to the backs of the insects for the first time. Lead researcher, JCU’s Dr Lori Lach, said the team glued Radio-Frequency Identification (RFID) chips to the backs of 960 bees, providing new insights into how disease affects the Continue Reading »

Examining the Neonicotinoid Threat to Honey Bees

Posted On: July 9, 2015

AMERICAN CHEMICAL SOCIETY The decline of honey bees has been a major concern globally for the past decade. One of the factors that could be contributing to the decline is the use of insecticides — specifically neonicotinoids — that persist in rivers and streams. Researchers now report in the ACS journal Environmental Science & Technology Continue Reading »

Surprisingly Few ‘Busy Bees’ Make Global Crops Grow

Posted On: June 17, 2015

University of Vermont A major international study finds that surprisingly few bee species are responsible for pollinating the world’s crops. The paper, published in Nature Communications, suggests that only two percent of wild bee species pollinate 80 percent of bee-pollinated crops worldwide. The study is one of the largest on bee pollination to date. While Continue Reading »
