Our plan is to evaluate the role, causative mechanisms, and interaction effects of biotic stressors (i.e. parasitic mites, pests, andpathogens) and abiotic stressors ((i.e. exposure to pesticides, poor habitat and nutrition, management practices) on the survival,health and productivity of honey bee colonies as well as within pollinator communities. Additionally we plan to develop and recommend "best practices" for beekeepers, growers, land managers and homeowners to promote health of honey bees and pollinator communities.
