Litsey, who received her master's degree in entomology in June and is now a laboratory technician in the lab of research entomologist Julia Fine, USDA/ARS, Davis,, will present her exit seminar on "Investigating a Novel Queen Honey Bee Treatment" at 4:10 p.m., Monday, Nov. 4 in 122 Briggs Hall. It also will be on Zoom. The Zoom link:

Later it be archived on the ENT seminar page.
"Juvenile hormone is an insect hormone known to regulate aspects of development and adult reproduction," she says in her abstract. "In honey bees, the role of juvenile hormone in reproduction is not well-explored, though its levels are correlated with many social behaviors and developmental pathways. A recent study demonstrated that queen exposure to the juvenile hormone mimic, pyriproxyfen, leads to higher egg hatching rates, and that the exposed queens' offspring perform more queen supportive behaviors than the offspring of control queens. The goal of this research is to further investigate the effects of queen exposure to pyriproxyfen as a potential queen treatment, using laboratory and field-based assays."
As a graduate student, Litsey specialized in bee biology, reproduction, and environmental toxicology. She also holds a bachelor's degree (June 2019) from UC Davis.
