How are pesticides impacting honey bee populations?
Several studies have been conducted on honey bee colony collapse disorder (CCD). It’s unclear the overall impact of pesticides on honey bees. Studies have revealed honey bees die from large pesticide concentrations that potentially interact with other pesticides. However, the studies have not tested environmentally relevant pesticides with concentrations more appropriate to farm usage. Further, the pesticides detected with the greatest frequency and quantities are those used by beekeepers to control mites. According to the USDA Agricultural Research Service, “Although a number of factors continue to be associated with CCD, including parasites and pathogens, poor nutrition, pesticides, bee management practices, habitat fragmentation, and agricultural practices, no single factor or pattern of factors has been proven to be “the cause” of CCD.” http://www.ars.usda.gov/is/br/ccd/ccdprogressreport2012.pdf
