Technology and connectivity: tipping the balance to save the world’s bees?

From: MemeBurn

As the growing network of smart, connected devices starts to change our world, scientists are increasingly looking to technology for new applications — often in the most unexpected spheres. With global bee populations already declining significantly and under new pressure from disease, an innovative technology-based solution could provide a new source of hope for bee farmers across the world. Called “MiteNot”, the technology is currently being trialled in America, with connectivity being provided by Gemalto’s machine-to-machine (M2M) module. Should trials prove effective, the solution might hold new hope for South Africa’s own bee populations – currently under threat from American Foul Brood Disease.

Researchers realize complexities of colony collapse disorder

As answers remain forthcoming on the toxicity of neonicotinoids to pollinators a mix of scientists and regulators recognize the need for more university research into potential causes of bee deaths know more commonly as colony collapse disorder (CCD).

Are Argentine ants a threat to honeybees?

From: University of California

You know them from the line across the kitchen counter and the swarm around your water faucet: Argentine ants. California sits atop a super-colony of these unwelcome houseguests, and new research suggests they may be doing more harm than previously suspected.

“There’s no evidence that the dicistrovirus found in Argentine ants does anything negative, and the presence of DWV in Argentine ants is only suggestive at this point,” says Tsutsui.

Varroa mite alert from the Honey Bee Lab

From: Oregon State University | College of Agricultural Science

Honey Bee Lab News

Hope all of you had a relatively successful bee year with strong hives and significant honey production, and have prepared your hives for successful overwintering. I just wanted to take this opportunity to alert / caution you about possibility of high mite populations in the colonies this year due to an unusually long bee season. As you all are aware we had a long bee season this year (at least in the Willamette Valley) as a result of warm weather that prevailed for almost more than 7 months. Longer brood cycle (abundance of larvae) usually results in higher mite populations, as the mites get a greater opportunity to breed and increase their populations relative to bees. Most of you might agree that this year was a year with longest brood cycle seen in the recent past (I have been in Oregon only for the past 6.5 years, so can’t go beyond that number). It has been reported that mite populations could increase exponentially (up to about 50 fold increase) in years when the brood is present in colonies almost round the year (Martin 1998).

As honeybees are lost, beekeepers and scientists grapple with potential causes

Which is the bigger threat?

An assistant entomology professor at the University of Maryland is hesitant to lay heavy blame on neonicotoid pesticide use. Dennis vanEnglesdorp, whose research has focused on honeybee health, said there has only been small numbers of beehives with traces of the pesticides in sampling work.

VanEnglesdorp said a big threat to honeybees is the Varroa mites, which is illustrated by the fact that large numbers of beekeepers are not treating for the mites.

USDA to EPA: “simple use of LD 50 toxicity ratings for individual bees. . .provides an inaccurate measure of potential harm. . .”

Editor’s Note: The following are excerpts from USDA Office of Pest Management Policy’s “Comments on the EPA proposed rule: Mitigation of Exposure to Bees from Acutely Toxic Pesticide Products” [EPA-HQ-OPP-2014-0818]. USDA’s complete comments are attached here.

USDA also requests clarification as to why this is listed as a proposed rule in EPA documents posted in the docket in May, June, and July 2015? When this action was first published in the Federal Register on May 29, 2015, it appeared in the Proposed Rules section of the Register and not in the Notices section where four other EPA notices appeared that same day. If this is a proposed rule and not a notice, why did this not follow procedures as described in the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)? An action such as this should be supported by an analysis of costs and benefits.

Argentine Ants Carry Virus Deadly to Honeybees

From: New York Times

By

The Argentine ant, already known as one of the world’s most widespread and damaging pests, may be infecting honeybees with a deadly virus, a new study finds.

***

She and her colleagues found that ants from all three locations can carry the deformed wing virus, a pathogen linked to colony collapse in honeybees. The new study appears in the current issue of the journal Biology Letters.

Researchers target mites that kill honeybees

From: Total Landscape

FROM


Varroa mites feed on bee larvae as well as lay their eggs on them.

The honeybee has to deal with multiple threats, but none as devastating as the varroa mite, according to the University of Florida. However, hope is on horizon for two different ways to possibly minimize the threat of these mites.

Varroa mites are parasites and feed on the blood-like substance of the worker bees and the larvae. Not only do the mites weaken the adult bees, they are also able to infect the larvae with a virus known as deformed wing virus. These infected larvae will not be able to fly as adults.

The ‘Genghis Khan of the ant world’, the Argentine ant, not only invades our suburbs. Researchers have now found it carries and spreads deadly pathogens.

However, ironically it appears the invasive ant may also host the seeds of its own destruction in the form of a killer virus.

A new study of Argentine ants in New Zealand, Australia and Argentina shows they carry a previously undescribed virus that could be connected to mass population collapses of the ants in New Zealand.
