In what may be the single largest mass bumblebee die-off on record, some 50,000 plus bees were recently found littering the parking lot of a Target store in Wilsonville, Oregon recently after a landscaping company sprayed surrounding trees with the insecticide Safari. Concerning shoppers and the community, the event also raised significant alarm amongst the Oregon Department of Agriculture, which has now enacted a temporary ban on the pesticide used in this incident, and for an additional 17 other insecticide products containing the chemical dinotefuran.

Dinotefuran, a popular insecticide found in agricultural, professional and household products is an insecticide of the neonicotinoid class, a class of insecticides widely suspected to be the primary cause of the global bee and pollinator die-off we are witnessing today. Neonicotinoidsinclude a number of other insecticides other than dinotefuran, and have for decades been suspected of being especially dangerous to bees:

“Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They includeimidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. According to the EPA, uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they relate to pollinators. Studies conducted in the late 1990s suggest that neonicotinic residues can accumulate in pollen and nectar of treated plants and represent a potential risk to pollinators.” [Beyond Pesticides]

 

Representing over 300 colonies and many potential future queen bees, the Oregon die off has caused considerable alarm and the Oregon department of health is acting swiftly: Read the rest of this entry
