WE WILL USE AN INTEGRATED RESEARCH AND EXTENSION PROJECT TO IMPROVE THE HEALTH OF HONEY BEES AND WILD BEES IN AGROECOSYSTEMS. OUR OVERALL HYPOTHESIS IS THAT BEES CAN THRIVE IN LANDSCAPES COMMITTED TO ANNUAL CROPS BY ADDRESSING THREE SOURCES OF STRESS: INSECTICIDES, FORAGE AVAILABILITY, AND PATHOGEN EXPOSURE. BEES FORAGE ON MANY ANNUAL CROPS WHEN IN BLOOM, INCREASING THEIR RISK OF INSECTICIDE EXPOSURE. WHEN THESE CROPS STOP BLOOMING, LIMITED ALTERNATIVE FORAGE IS AVAILABLE. NATIVE, PERENNIAL HABITAT (E.G. PRAIRIE) CAN PROVIDE ABUNDANT FLORAL RESOURCES FOR BEES AT CROP SENESCENCE TIME. RECENT WORK SUGGESTS HIGH QUANTITY AND QUALITY FORAGE CAN IMPROVE BEE HEALTH, EVEN IN THE FACE OF INSECTICIDE AND PATHOGEN STRESS. WE WILL DETERMINE IF REDUCING INSECTICIDE USE VIA IPM, COMBINED WITH MOVING HONEY BEES TO PRAIRIES AFTER CROP BLOOM, CAN RESCUE THEM FROM THE NEGATIVE IMPACTS OF AGRICULTURAL INTENSIFICATION. BECAUSE HONEY BEES MAY COMPETE WITH OR TRANSMIT PATHOGENS TO WILD BEES, CONSERVATIONISTS MAY RESIST USING PRAIRIE FOR BEEKEEPING. THEREFORE, WE WILL ALSO INVESTIGATE THE EFFECTS OF KEEPING HIVES, IN BOTH CROPS AND PRAIRIES, ON WILD BEE HEALTH INDICATORS. THIS WORK WILL BE ACCOMPLISHED THROUGH ON-FARM, LANDSCAPE-SCALE EXPERIMENTS, LAB STUDIES, AND MEASUREMENTS OF NUMEROUS BEE HEALTH INDICATORS. WE WILL IMPLEMENT OUR RESEARCH RESULTS INTO SOLUTIONS THROUGH AN IN-DEPTH EXTENSION PROGRAM, REACHING OUT TO AND INCREASING THE KNOWLEDGE OF MULTIPLE STAKEHOLDER GROUPS. BY INCORPORATING SURVEY INFORMATION ON STAKEHOLDER ATTITUDES, PRACTICES, AND RESPONSES TO OUR RESEARCH; AND BY COLLABORATING WITH KEY GOVERNMENTAL AND INDUSTRY PARTNERS, WE WILL DEVELOP RECOMMENDATIONS TO ADDRESS POLLINATOR DECLINE, AND BRIDGE INFORMATION GAPS BETWEEN FARMERS, BEEKEEPERS AND CONSERVATIONISTS.
