Virus Attracts Bumblebees to Infected Plants by Changing Scent

Posted On: August 12, 2016

University of Cambridge Plant scientists at the University of Cambridge have found that the cucumber mosaic virus (CMV) alters gene expression in the tomato plants it infects, causing changes to air-borne chemicals – the scent – emitted by the plants. Bees can smell these subtle changes, and glasshouse experiments have shown that bumblebees prefer infected Continue Reading »

Pesticides Used to Help Bees May Actually Harm Them

Posted On: August 9, 2016

Pesticides beekeepers are using to improve honey bee health may actually be harming the bees by damaging the bacteria communities in their guts, according to a team led by a Virginia Tech scientist. The discovery, published in the journal Frontiers in Microbiology, is a concern because alterations can affect the gut’s ability to metabolize sugars Continue Reading »

Researchers Identify How Queen Bees Repress Workers’ Fertility

Posted On: August 4, 2016

University of Otago  Researchers from New Zealand’s University of Otago have discovered the molecular mechanism by which queen honey bees carefully control worker bees’ fertility. It has long been known that worker bees have a very limited ability to reproduce in a hive with a queen and brood present, but in their absence, a third Continue Reading »

Deformed Wing Virus: Honeybees Threatened by a More Virulent Virus

Posted On: July 5, 2016

According to an international research group, a genetic variant of the deformed wing virus (DWV) is more dangerous to honeybees than the original virus strain. The consortium of researchers is based at Freie Universität Berlin and Martin Luther University Halle-Wittenberg. The emerging variant could represent a threat to honeybees worldwide and is probably already widespread Continue Reading »

USDA Scientists and Beekeepers Swap Colonies to Better Bees

Posted On: June 21, 2016

By Kim Kaplan Agricultural Research Services, USDA BELTSVILLE, Md., June 21, 2016 —The U.S. Department of Agriculture‘s (USDA) Agricultural Research Service (ARS) Bee Research Laboratory and Geezer Ridge Farm apiary have begun an unusual partnership that may help honey bees take another step up the survival ladder. “Usually with science, researchers finish a study and Continue Reading »

New Study on Grooming Behaviour by Honey Bees Against Varroa

Posted On: June 13, 2016

In a new study, scientists have compared the ability of two strains of honey bees to defend themselves against the parasitic mite varroa by grooming the mites from their bodies. The varroa mite Varroa destructor is generally considered to be the greatest threat to honey bees worldwide because it transmits virus diseases which lead to Continue Reading »

Parasitic Cape Honey Bees Out-Reproduce Other Bees Using a Few Unusual Gene Regions

Posted On: June 13, 2016

Genes related to hormone signaling and sex cell division let worker bees reproduce asexually PLOS Parasitic cape honey bees exploit and overrun other honey bee colonies by triggering changes that let worker bees reproduce. This social parasitism is enabled by differences in several gene regions, including some related to hormone signaling and chromosomal segregation, report Continue Reading »

Honey Bees Pick Up ‘Astonishing’ Number of Pesticides Via Non-crop Plants

Posted On: May 31, 2016

Purdue University WEST LAFAYETTE, Ind. – A Purdue University study shows that honey bees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season. Christian Krupke, professor Continue Reading »

Dancing Hairs Alert Bees to Floral Electric Fields

Posted On: May 31, 2016

(University of Bristol)   Tiny, vibrating hairs may explain how bumblebees sense and interpret the signals transmitted by flowers, according to a study by researchers at the University of Bristol. Although it’s known that flowers communicate with pollinators by sending out electric signals, just how bees detects these fields has been a mystery – until Continue Reading »
