** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** COLORADO POTATO BEETLE IS A MAJOR PEST OF POTATO THAT HAS EVOLVED RESISTANCE TO MOST PESTICIDES, SPURRING THE SEARCH FOR ALTERNATIVE MANAGEMENT STRATEGIES SUCH AS BIOLOGICAL CONTROL. AN IMPORTANT COMPONENT OF THE PREDATOR EFFECT ON PREY IS THE NON-CONSUMPTIVE EFFECT, WHICH OCCURS WHEN PREY DETECT AND AVOID PREDATION USING COSTLY RESPONSES. THIS HAS BEEN SHOWN TO REDUCE PEST NUMBERS AND PROTECT PLANTS FROM DAMAGE IN MANY CROPPING SYSTEMS. NON-CONSUMPTIVE EFFECTS REPRESENT A NOVEL TACTIC FOR PEST MANAGEMENT, BUT NOT BEING ABLE TO TRIGGER PREY RESPONSES IN THE ABSENCE OF LIVE PREDATORS HAS LIMITED THEIR USE. WE HAVE FOUND THAT WE CAN ELICIT NON-CONSUMPTIVE EFFECTS IN COLORADO POTATO BEETLE BY RELEASING THE PHEROMONE OF THE PREDACEOUS SPINED SOLDIER BUG PODISUS MACULIVENTRIS, AND IN FIELD TRIALS WE FIND THIS TO REDUCE BEETLE ABUNDANCE AND PLANT DAMAGE, AND TO INCREASE POTATO TUBER YIELD. IN ADDITION, THE COLORADO POTATO BEETLE AGGREGATION PHEROMONE HAS RECENTLY BEEN SYNTHESIZED, AND IS HIGHLY ATTRACTIVE TO BOTH MALE AND FEMALE BEETLES. CRITICAL TO DEVELOPING A DUAL ATTRACTANT-DETERRENT MANAGEMENT SYSTEM USING THESE TWO PHEROMONES IS UNDERSTANDING 1) THEIR COMMUNITY WIDE EFFECTS ON OTHER PESTS AND BENEFICIALS AND 2) THE MOST EFFECTIVE SPATIAL SCALES FOR THEIR DEPLOYMENT. BECAUSE BOTH PHEROMONES CAN BE SYNTHETICALLY PRODUCED, THEY CAN MORE EASILY BE DEPLOYED IN THE FIELD AND THEY HAVE THE POTENTIAL TO FACILITATE A HEALTHIER AND MORE SUSTAINABLE VEGETABLE PRODUCTION SYSTEM. THIS PROJECT SUPPORTS THE PESTS AND BENEFICIAL SPECIES IN AGRICULTURAL PRODUCTION SYSTEMS PROGRAM PRIORITY OF INNOVATIVE BIOLOGICALLY BASED STRATEGIES TO MANAGE PESTS.
