Bee Colony Collapse Associated with Viral, Fungal Infection

11.10.2010
The sudden death of bee colonies since late 2006 across North America has stumped scientists. But today, researchers may have a greater understanding of the mysterious colony collapse disorder, said a Texas Tech University biologist.

Shan Bilimoria, a professor and molecular virologist, said the bees may be taking a one-two punch from both an insect virus and a fungus, which may be causing bees to die off by the billions.

Bilimoria is part of a team of researchers searching for the cause of the collapse. Led by research professor Jerry Bromenshenk from the University of Montana in Missoula, the group also includes virologists and chemists from the U.S. Army Edgewood Chemical Biological Center and the Instituto de Ecologica AC in Mexico.

Their study was published this week in the peer-reviewed journal PLoS ONE.

“At this stage, the study is showing an association of death rates of the bees with the virus and fungus present,” Bilimoria said. “Our contribution to this study confirms association. But even that doesn’t prove cause and effect. Not just yet.”

The mysterious colony deaths have caused major concern with scientists since much of agriculture depends on bees to pollinate crops.

To discover what might be attacking bee colonies, the team ground up dead bees that had succumbed to colony collapse disorder. Using analytical equipment, researchers discovered through spectroscopic analysis evidence of a moth virus called insect iridescent virus (IIV) 6 and a fungal parasite called Nosema.

The insect virus is closely related to another virus that wiped out bee populations 20 years ago in India, he said. Also, unlike previous research that found the deaths may be caused by a virus with RNA, the IIV 6 contains DNA.

“Our DNA discovery puts this field in a whole new direction,” he said.

Bilimoria said Texas Tech supplied the virus material for the experiments and were tested on bees with the fungus. Though an association between exposure and death was found, scientists don’t yet know if the two pathogens cause CCD or whether CCD colonies are more likely to succumb to the two pathogens.

“To prove cause and effect, we will have to isolate the virus and fungus from bee colony, and then reinfect with same virus and fungus,” Bilimoria said.

In the next part of the research project, Bilimoria will work to isolate the virus from infected bees.

“Once we isolate and identify the virus, we will have a way of monitoring it,” he said. “It is easier to fight the problem if we know what the culprit is.”

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
