BEES PROVIDE IMPORTANT POLLINATION SERVICES THAT CONTRIBUTE TO NEARLY ONE THIRD OF OUR FOOD SUPPLY. HONEY BEES IN PARTICULAR PROVIDE THE MAJORITY OF POLLINATION TO CROPS; HOWEVER, DUE TO THEIR DECLINES, IT IS IMPERATIVE TO UNDERSTAND NATIVE BEE ECOLOGY TO PROVIDE THEM WITH SUITABLE HABITAT AND REDUCE POTENTIAL POLLINATION DEFICITS CAUSED BY FEWER HONEY BEES. FURTHERMORE, MANY AGROECOSYSTEMS BECOME A FOOD DESERT FOR BEES AFTER CROP BLOOM. BUMBLE BEES ARE IMPORTANT NATIVE POLLINATORS IN A VARIETY OF POLLINATION DEPENDENT CROPS DUE TO THEIR ABUNDANCE AND ABILITY TO BUZZ POLLINATE. THE COMMERCIAL AVAILABILITY OF BUMBLE BEES (BOMBUS IMPATIENS AND BOMBUS HUNTII) IN THE UNITED STATES OFFERS AN ALTERNATIVE TO HONEY BEES IN MANY CROP SYSTEMS. UNFORTUNATELY, THEIR FORAGING ECOLOGY IS POORLY UNDERSTOOD, ESPECIALLY IN REGARDS TO FORAGING RANGE AND NESTING DENSITY. ILLUMINATING BASIC QUESTIONS SUCH AS FORAGING RANGE CAN SHED LIGHT ON UNKNOWN FACTORS PLAGUING NATIVE BEE POPULATIONS SUCH AS REALISTIC FORAGE AVAILABILITY AND RATE OF PATHOGEN SPREAD, WHICH CAN HELP US BETTER INFORM CONSERVATION PRACTICES IN AGROECOSYSTEMS.THE OBJECTIVES OF THIS STUDY ARE TO (1) DETERMINE FORAGING RANGE OF COMMERCIALLY AVAILABLE B. IMPATIENS COLONIES, (2) DETERMINE FORAGING RANGE AND NESTING DENSITY OF WILD BUMBLE BEE SPECIES IN AGRICULTURAL LANDSCAPES, AND (3) MODEL DISEASE TRANSMISSION IN BUMBLE BEES BASED ON FORAGING RANGE IN AGRICULTURAL LANDSCAPES. RESULTS FROM THIS STUDY WILL INFORM BEST HABITAT MANAGEMENT PRACTICES TO CONSERVE NATIVE BUMBLE BEE POPULATIONS BY PROVIDING AN ENHANCED UNDERSTANDING OF WHERE HABITAT ENHANCEMENT IN AGROECOSYSTEMS SHOULD BE PLACED IN RELATION TO PRIME NESTING HABITAT.
