Responsibilities and Past Research:
Ms. Zarrillo has provided assistance in the field and laboratory for research projects dealing with bee pollination, pesticides, floral preference trials, and wild bee diversity in Connecticut. She initiated and coordinates the Wild Bee Monitoring Program in Connecticut, which includes cooperators at the White Memorial Conservation Center in Litchfield, the Stewart B. McKinney National Wildlife Refuge in Westbrook, and CAES campuses around the state. She has examined wild bee communities living in Connecticut's maritime habitats and has identified potential threats due to climate change and non-native plant species. In addition to her bee work, she has also assisted in natural history surveys of longhorn beetles, exotic insect surveys, and surveys of bio-control agents for emerald ash borer throughout Connecticut.
Focus of Current Research:
Ms. Zarrillo is currently writing a checklist of the wild bees of Connecticut. She is also collaborating with the Connecticut Department of Energy and Environmental Protection on a meadow restoration project and will be monitoring the response of wild bees and monarchs to the improved habitat over time. She conducts surveys for rare and/or threatened wild bee species in Connecticut and is interested in the biology of bees that specialize on specific types of pollen.
