    Default 25,000 bumblebees killed, dropping from trees in Wilsonville; pesticide suspected

    An estimated 25,000 bumblebees have been found dead in a Target parking lot in Wilsonville since Saturday, the largest known incident of bumblebee deaths in the United States, according to the Xerces Society. Preliminary information suggests pesticides may be at fault.

    The Oregon Department of Agriculture received reports of bees and other insects falling out of 55 blooming European linden trees Monday from the Xerces Society for Invertebrate Conservation.

    The bees were still dying on Wednesday. Yellow-faced bees fell from the trees, twitching on their backs or wandering in tight circles on the asphalt. Some honeybees and ladybugs were also found dead. A few dead bumblebees even clung to linden flowers, while hundreds littered the lot.

    Dan Hilburn, director of plant programs at the state Agriculture Department, surveyed the damage after an earlier assessment from pesticide experts.

    "I've never encountered anything quite like it in 30 years in the business," he said Wednesday outside the Argyle Square Target.

    Hilburn said initial findings indicate the trees were sprayed Saturday with an insecticide called Safari. Tests to confirm what killed the bees will take at least two or three days, department officials said. The department of agriculture is also investigating other possible culprits, which may include other pesticides used in the surrounding area.

    Safari is part of the neonicotinoid pesticide family. When it is sprayed on a plant, the leaves, flowers and nectar become toxic to almost all insects. The product's label on the distributor's website warns it is "highly toxic" to bees and tells applicators not to apply it "if bees are visiting the area."

    "Bumblebees are the single most important natural pollinator in Oregon," said Mace Vaughan, pollinator program director for Xerces.

    They play a crucial role in pollinating berries, flowers and other plants. The decline of the honeybee, whose populations have been decimated by Colony Collapse Disorder, has received much attention, but bumblebee populations are decreasing as well.

    Elliot Associates Inc., the company that rents and manages the Argyle Square land, did not respond to multiple calls by The Oregonian. The landscapers that care for the grounds couldn't be reached for comment.

    The Agriculture Department is working with the Xerces Society to help mitigate any further insect deaths at Argyle Square. As precautionary moves, they are considering either putting up netting around the trees, stripping off flowers and leaves or finding non-toxic repellents to keep bees and insects from eating the leaves or nectar.

    Dale Mitchell, pesticide compliance program manager for the state agriculture department, said if test show pesticide is the culprit, the department will assess if the company responsible violated any state or federal laws, and if so, the severity of those violations. Fines for pesticide regulation infractions can range from $1000 to $10,000.

    The bumblebee deaths marked an inauspicious start to National Pollinator Week, which runs through June 23.

    How does this relate to CCD?

    CCD is related to the use and overuse and misuse of pesticides. by the looks of it, a colony of bumblebees **** the bed.

    a rather small drop in the bucket i suppose....but it just goes to show those using chemicals need to be more responsible for the deaths of our pollinators.

    Conservation groups keep telling us bumblebees are in worrisome decline due, in part, to urbanization causing a loss of habitat. If that is true
    then how come there were 25,000 bumblebees in the Oregon shopping center parking lot in question?

    I expect they planted the linden trees specifically to attract pollinators.

    Because that shopping center is right next to some giant open fields which is probably host to the lion's share of bumbles in the whole area.

    I don't believe CCD has been attributed to anyone cause. I also don't believe anyone is attributing acute pesticide kills to CCD.

    Bumble bee colonies are significatly smaller than honey bee colonies. Bumble bee colonies often consist of only 50 adults. So, the killing of 25,000 bumble bees represents thousands of colonies.

    1) The 25,000 dead bees figure must be wildly exaggerated because there are only 55 Linden trees in the Target store parking lot and likely only dozens of bumblebees per tree. So that means only hundreds of bumblebees likely died.

    2) Collisions with cars likely kill hundreds of bumblebees PER (sunny) DAY in Wilsonsonville. So this parking lot kill is minor and trivial by comparison.

    3) The fact that there were at least hundreds of bumblebees nectaring in the Target store parking lot Linden trees proves bumblebees are abundant in the region despite urbanization and associated pesticide use and daily car collision kills.

    Update: Thousands of bumblebees did really die in a shopping center parking lot: http://www.xerces.org/wp-content/upl...8-1024x768.jpg

    I find it ironic that will all the hype of "vanishing bumblebees due to habitat loss" thousands of them could actually be found in a 1 acre suburban asphalt habitat!

    Ah. More bees! I hear neonics will kill pollinators for a long time yet.
