**AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** SOCIAL INSECT POLLINATORS ARE CRITICAL TO SUCCESSFUL AGRICULTURAL PRACTICES. SPECIFICALLY, BEES PROVIDE BUZZ-POLLINATION TO ESSENTIAL FOOD CROPS. HOWEVER, NATURAL POPULATIONS OF BEES MAY BE HARMED BY ANTHROPOGENIC PESTICIDE USE IN THE ENVIRONMENT. UNFORTUNATELY, THE INDIRECT EFFECTS OF PESTICIDE EXPOSURE ON THE INTEGRATED DEVELOPMENT FOUND IN SOCIAL INSECT SOCIETIES REMAINS POORLY UNDERSTOOD. IN PARTICULAR, PESTICIDES MAY LEAD TO UNUSUAL DEVELOPMENTAL EFFECTS IN SOCIAL INSECTS BECAUSE QUEENS, WORKERS, AND MALES ALL ARISE FROM THE SAME GENOME. OUR LACK OF UNDERSTANDING OF HOW ENVIRONMENTAL CONTAMINANTS, SUCH AS PESTICIDES, AFFECT THE DEVELOPMENTAL GENETICS OF SOCIAL POLLINATORS REPRESENTS A MAJOR GAP IN OUR UNDERSTANDING OF THE EFFECTS OF PESTICIDES ON POLLINATORS, SPECIFICALLY, AND SOCIAL INSECTS, IN GENERAL. THIS PROJECT WILL INVESTIGATE HOW PESTICIDES AFFECT THE INTEGRATED DEVELOPMENTAL PROCESSES THAT SOCIAL INSECT POLLINATORS REQUIRE BY EXAMINING CHANGES IN GENETIC CORRELATIONS OF MORPHOLOGY AND GENE EXPRESSION WHEN PESTICIDES STRESS THE COLONY. THIS RESEARCH WILL PROVIDE NOVEL INSIGHT INTO HOW ENVIRONMENTAL TOXICANTS AFFECT THE DEVELOPMENTAL PROCESSES DISPLAYED BY SOCIAL INSECT POLLINATORS.
