Ed Rajotte, Ph.D.
Professor of Entomology and IPM Coordinator
Current Graduate Students:
Department Focus Areas:
IPM, international agriculture, pest management policy, biology of fruit pests, pollination and apiculture (http://www.youtube.com/watch?v=IYKVI8ayzsw)
Integrated Pest Management, Comparative European and U.S. Agriculture
Integrated pest management; international agriculture; IPM in schools, urban IPM programming.
Research Activities & Interests :
My research focuses on insect ecology and management in support of integrated pest management systems. Domestically, I concentrate on biological, social and economic issues in integrated pest management, bee management and pollination, pest management in under-served urban neighborhoods and fruit IPM. Internationally, I have had projects in South Asia, Southeast Asia, Eastern Europe and North Africa primarily designing and testing IPM approaches in tropical vegetables, IPM information systems and impact analysis.
Extension Activities & Interests:
As IPM Coordinator for Pennsylvania Cooperative Extension, I represent and promote IPM with federal, state and municipal governments; represent Pennsylvania to state and federal policy-making bodies on pest management issues; coordinate IPM in schools and urban environments. Our extension IPM programs are team efforts involving close cooperation among members of the entomology department and extension faculty and staff in other departments and in the counties. The Pennsylvania IPM Program represents Penn State's disciplines including entomology, plant pathology, weed science, nematology and others.
