Christina Grozinger is an American entomologist, the Publius Vergilius Maro Professor of Entomology at Pennsylvania State University[1] and the director at its Center for Pollinator Research.
[2] Her main areas of expertise as a social insect biologist are the molecular, physiological, and ecological determinants that affect the health of honey bees and other pollinators.
Her group has determined that bee's resilience against diseases and pesticides is improved if they have access to high quality nutritional resources from multiple sources.
Understanding bees’ nutritional needs is an important step towards pollinator habitat restoration and the improvement of beekeeping practices.
[5] Grozinger recommends strategies for floral planting in a variety of landscapes to improve pollinator nutrition, and provides support tools for work in agriculture, conservation, and community settings.
[3][11][12] Assessing an area from the viewpoint of research-based bee nutrition makes it possible to create "ecologically functional landscapes".
She has shown that immune challenges can alter the surface chemical profiles of insects, which affect their social interactions and possibly the spread of disease.
