Research Area
- 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.
