Etya Amsalem

Etya Amsalem is an Associate Professor in the Department of Entomology at Pennsylvania State University, affiliated with the College of Agricultural Sciences. Her research focuses on social insect biology, particularly bumblebees (Bombus spp.), examining topics such as reproductive signaling, environmental stressors (e.g., pesticides, CO2), and physiological adaptation. She investigates pheromone communication, caste determination, diapause survival, and the impacts of pollutants on pollinator health.

Key research themes include: 1) Chemical ecology of social insect communication, 2) Ecotoxicological effects of pesticides on pollinators, 3) Hormonal regulation of reproduction and behavior, and 4) Evolutionary mechanisms of social organization. Recent work highlights how sublethal pesticide exposure disrupts mating and chemical signaling, and how CO2 narcosis interacts with juvenile hormone pathways.

Her 15 most recent articles (2022–2025) span topics like bumblebee nutritional choices, pheromone evolution, and diapause resilience. Though no formal student listings are provided, her publications suggest collaborative work with graduate students and postdocs. Awards/grants are not explicitly mentioned in the provided text.
