TL;DR: A broad survey of pesticide residues was conducted on samples from migratory and other beekeepers across 23 states, one Canadian province and several agricultural cropping systems during the 2007–08 growing seasons, finding 121 different pesticides and metabolites within 887 wax, pollen, bee and associated hive samples.
Journal ArticleDOI
Colony Collapse Disorder: A Descriptive Study
Dennis vanEngelsdorp,Jay D. Evans,Claude Saegerman,Christopher A. Mullin,Eric Haubruge,Bach Kim Nguyen,Maryann Frazier,J. L. Frazier,Diana Cox-Foster,Yanping Chen,Robyn M. Underwood,David R. Tarpy,Jeffery S. Pettis +12 more
TL;DR: This is the first comprehensive survey of CCD-affected bee populations that suggests CCD involves an interaction between pathogens and other stress factors, and presents evidence that this condition is contagious or the result of exposure to a common risk factor.
Journal ArticleDOI
Pesticides and honey bee toxicity – USA
TL;DR: The role that pesticides and their residues in hive products may play in colony collapse disorder and other colony problems is discussed.
Journal ArticleDOI
Four Common Pesticides, Their Mixtures and a Formulation Solvent in the Hive Environment Have High Oral Toxicity to Honey Bee Larvae
TL;DR: It is suggested that pesticide mixtures in pollen be evaluated by adding their toxicities together, until complete data on interactions can be accumulated, and that chronic dietary exposure to a fungicide, pesticides mixtures, and a formulation solvent have the potential to impact honey bee populations.
Journal ArticleDOI
In-hive Pesticide Exposome: Assessing risks to migratory honey bees from in-hive pesticide contamination in the Eastern United States
Kirsten S. Traynor,Jeffery S. Pettis,David R. Tarpy,Christopher A. Mullin,J. L. Frazier,Maryann Frazier,Dennis vanEngelsdorp +6 more
TL;DR: It is found that fungicides with particular modes of action increased disproportionally in wax within colonies that died, and the occurrence of queen events, a significant risk factor for colony health and productivity, was positively associated with all three proxies of pesticide exposure.
