Corn Seed Treatment As Lethal As It Gets For Honey Bees All Season Long, And Long After The Season Has Gone. It Just Keeps On Killing.
Frightening new research shows honey bees are being exposed to deadly neonicotinoid insecticides and several other agricultural pesticides throughout their foraging period. The research, published in the scientific journal PLoS One says extremely high levels of clothianidin and thiamethoxam were found in planter exhaust material produced during the planting of treated maize seed. The work, which could raise new questions about the long-term survival of the honey bee, was conducted by Christian H. Krupke of the Department of Entomology at Purdue University, Brian D. Eitzer of the Department of Analytical Chemistry at the Connecticut Agricultural Experiment Station and Krispn Given of Purdue.
Neonicotinoids were found in the soil of each field we sampled, including unplanted fields, they report. Dandelions visited by foraging bees growing near these fields were found to contain neonicotinoids as well. “This indicates deposition of neonicotinoids on the flowers, uptake by the root system, or both,” the report says. “Dead bees collected near hive entrances during the spring sampling period were found to contain clothianidin as well.” Read more: http://home.ezezine.com/1636/1636-2012.01.04.21.46.archive.html
