Protecting Bee Health is a Long-Term Commitment

From: ValdostaToday.com

U.S. Congressman Austin Scott (GA-08), Chairman of the House Agriculture Committee’s Subcommittee on Horticulture, Research, Biotechnology and Foreign Agriculture for Valdosta Today:

For those in agriculture, harvest season is a busy time. Farmers nurture their fields all year, which leads to feeding our families and much of the world. Most growers involved in horticulture production know that their long hours are matched by the non-stop effort of bees, which remain a critical component of our nation’s food supply. The harvest of fruits, nuts, vegetables, ornamentals, and greenhouse crops are dependent upon the bee colonies in the United States.

50 million year old mite attached to ant head found in piece of amber

From: Phys.org

by Bob Yirka

A small team of researchers with members from several countries has identified the oldest known instance of a type of mite fossil. In their paper published in the journal Biology Letters, the team describes how they obtained a piece of amber with an ant embedded inside of it along with a mite that was attached to the ant’s head, and what their work revealed.

EXTENSION CONNECTION: Pesticide labels help protect bees

From: Crestville News Bulletin

By SHEILA DUNNING / University of Florida Institute of Food and Agricultural Sciences Extension

Watch for changes on pesticide labels that contain pollinator-protection language.

Language to protect pollinators has always been on the label, but now the verbiage specifically prohibits foliar applications while bees or flowers are present, or until all petals have fallen off. Presence of all blooming plants, including weeds such as clover and Spanish needle, must be evaluated before treating with certain pesticides.

How do Varroa Mites Know when to Leave Honey Bee Hives? It’s all in the Bees’ Wax

From: Entomology Today

 by

Although they are really tiny, the Varroa mite has the potential to bring large parts of western agriculture to its knees by infesting and destroying honey bee hives. Varroa mites are the “single most detrimental pest of honey bees,” according to the USDA National Honey Bee Health Stakeholder Conference Steering Committee. In addition to attaching to and feeding on the bees, Varroa mites can spread harmful viruses and reduce bee immunity.

Bee careful out there – a parasitic marauder is nearly at our shores

From: The Sydney Morning Herald

Honeybees lead something of a charmed life, as they flit about collecting nectar and pollen and producing oodles of honey and wax. But now, it seems, their carefree days might soon be numbered.

Populations of the four-winged insects, which pollinate the flowers of at least one-third of wild and farmed plants that humans eat, have decreased over the past three decades in the US and Britain. In part, this has been due to the prevalence of crop pesticides, the destruction of flower-rich habitats and pests.

Use caution when reading new bee and pesticide research

From: University of Minnesota

By Jeffrey Hahn, Extension Entomologist, May 23, 2014

New research about bees and pesticides from Harvard University was recently published by Lu et al. in the Bulletin of Insectology. This research examined honey bee colonies that were fed high fructose corn syrup (HFCS) contaminated with two common neonicotinoids (imidacloprid or clothianidin) during late summer and then observed in the following spring. Both the control colonies and the insecticide exposed colonies did well going into fall. While both sets of colonies then declined, the control colony numbers rebounded while the insecticide exposed colonies suffered large losses. The authors’ conclusions are that insecticides are the leading explanation for colony collapse disorder (CCD).

Of Bees, Mites and Viruses

From: Asian Scientist

A study documents the spread of bee-killing viruses through New Zealand via the parasitic mite Varroa destructor.

AsianScientist (Aug. 27, 2014) – Honeybee colonies are dying at alarming rates worldwide. A variety of factors have been proposed to explain their decline, but the exact cause—and how bees can be saved—remains unclear. An article published in PLOS Pathogens examines the viral landscape in honeybee colonies in New Zealand after the recent arrival of the parasitic Varroa destructor mite.

The Killer Mite Wiping Out Honey Bees Around The World Has Reached New Zealand

From: Business Insider Australia

Chris Pash

The Varroa mite, the main suspect behind the collapse of bee populations around the world, has landed in New Zealand.

And scientists are using the opportunity to monitor the effects of early infestation on bees and their viruses.

So far, they’ve found seven different bee virus species which have responded in a unique way to the arrival, establishment and persistence of the mite.

Varroa feeds on the blood of pupae and adult bees and can transmit several honeybee viruses with high efficiency.

Scientists, beekeepers unite to stop parasitic varroa mite from threatening Australia’s honey industry

From: Australian Broadcasting Corporation/News

By Selina Bryan

The Tasmanian Government, CSIRO and beekeepers have teamed up to fight a pest that could threaten Australian food production.

The varroa destructor is a parasitic mite that attacks honey bees.

Around the world it has already reduced honey bee numbers and affected food crop pollination.

“Estimates from a report released last year have put [the potential cost] to at least about $1.3 billion over the next 30 years,” said Stephen Quarrell, an entomologist from the University of Tasmania.
