EDUCATION:

• B.S., Ecology & Evolutionary Biology, Purdue University, 1985
• Ph.D., Entomology, Purdue University, 1990.

DEPARTMENT HEAD RESPONSIBILITIES:

• Administration of teaching and research functions of the Department
• Discipline liaison with Cooperative Extension Service
• Disciplinary support of faculty at research and extension centers statewide
• Represent discipline to state agencies, commodity groups and general public

GENERAL AREAS OF INTEREST:

SPECIFIC AREAS OF RESEARCH:

• Dr. Wiedenmann has conducted basic and applied research on biological control of insects and weed pests, and on the biology of parasitic and predaceous insects. His interests center on the foraging strategies of parasitic Hymenoptera that attack stemboring Lepidoptera; biological control of purple loosestrife, garlic mustard and teasel (exotic, invasive weeds); and integration of transgenic technology into IPM.
