Researchers in Connecticut, during the 2007 growing season monitored pesticides found in pollen collected in pollen traps. Colonies studied were under normal conditions and were not collapsing or in any other way ill. No colonies died during the experiment.

The researchers collected the pollen twice a week from four locations in Connecticut during the season. 102 Samples were collected and analyzed using HPLC/MS. (High Performance Liquid Chromatography/ Mass Spectrometry)

Results: 37 pesticides were detected. 15 insecticide/ acaracides, 11 fungicides, 10 herbicides and 1 plant growth regulator. All samples had at least one pesticide detected.

The most commonly detected pesticide was coumaphos. Carbaryl and phosmet, both highly toxic to bees were the most commonly detected field pesticides. Imidacloprid was detected 30 times, mostly at low levels. The pesticides found at the highest levels were both fungicides: myclobutanil and boscalid.
