CCD diagnosis – 06/22/2007

  • November 30, 2013 at 11:57 pm #1574

    I (Mike C) have just one question:
    I know CCD started in earnest in the Fall 2006 and Spring 2007;
    How long have the neonicotinoid pesticides mentioned in this article
    been in use? I for one am not buying this explanation until it is
    proven scientifically….

    from mirakulu2003:

    ISIS Press Release 22/06/07
    Emergency Motion on Protecting the Honeybee

    Question Tabled to European Commission by Ms Hiltrud Breyer MEP of

    Honeybees have been disappearing worldwide. 1 Across the United
    States, beekeepers have been losing 30 to 90% or more of colonies in a
    “colony collapse disorder” (CCD) that’s causing huge economic losses
    not only to beekeepers but also to fruit and vegetable growers. CCD
    has been reported from Germany, Switzerland, Spain, Portugal, Italy,
    Greece, and the UK. Many believe that when the honeybee disappears,
    our species will soon follow.

    The most important single factors identified by the Institute of
    Science in Society ( ), in CCD were sub-lethal levels
    of insecticides, 2 in particular, a class of new systemic
    neonicotinoid pesticides widely used to dress seeds and in sprays on
    crops, 3 and microwave radiation from wireless telephone transmitters
    and base stations. 4

    Sub-lethal levels of pesticides, including the Bt biopesticides
    produced in genetically modified (GM) crops covering some 30 percent
    of the global area, disorientate the bees, making them behave
    abnormally, and compromise their immunity to infections.

    A report in the LA Times 5 suggested that a single cell parasitic
    fungus, Nosema ceranae , may be responsible for CCD, though the
    experts involved said the results are “highly preliminary”.

    A new review from ISIS 6 presented compelling evidence that sub-lethal
    levels of neonicotinoid pesticides, particularly imidacloprid, act
    synergistically with parasitic fungi such as Nosema in killing insects
    pests. Fungal spores, widely used as biocontrol agents are applied in
    sprays and baits, and when delivered in suspension with sub-lethal
    levels of pesticides are much more effective in killing insects.

    Equally, Bt biopesticides enhance the killing power of parasitic fungi
    synergistically. Purified Bt Cry1Ab toxin killed Nosema infected borer
    larvae at one-third the dose required for killing the uninfected
    larvae. Bacillus thuringiensis kurstaki (the natural soil bacteria
    producing the Bt biopesticides) in commercial (Dipel) formulations
    killed Nosema pyrausta infected cornborer larvae at a dose 45 times
    lower than that killing the uninfected larvae.

    Regulators have allowed the widespread deployment of systemic
    neonicotinoid pesticides neonicotinoids based on assessments of lethal
    dose in bees of the pesticides alone, ignoring clear evidence that
    sub-lethal pesticide levels act synergistically with fungal parasites
    in killing insects. The honeybees may well be succumbing to such
    synergistic effects. There is every reason to eliminate the use of all
    pesticides that act synergistically with parasitic fungi, and all Bt
    crops should be banned for the same reason.

    Will the European Commission take the appropriate measures to halt the
    colony collapse of the honeybees?

    This would include banning Bt crops and systemic neonicotinoid
    pesticides while their synergistic action in killing honeybees in
    combination with parasitic fungi and other infections are thoroughly
