Stephen L. Clement

Adjunct Faculty, Department of Entomology, Washington State University, Pullman, WA.

(Retired) Research Entomologist and Lead Scientist, U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS), Plant Germplasm Introduction and Testing Research Unit, Washington State University. Pullman, WA. 1986-2010.

Areas of Interest:

-Development and implementation of sustainable solutions (biological control, host-plant resistance) for pest problems that adversely affect food legume, rice, maize, wheat, and forage grass production in the U.S. and other countries. Overseas work in southern Europe, Australia, New Zealand, and India.

-Plant and microbial biodiversity (acquisition, conservation, re-generation, use).

-Biological weed control (foreign exploration, host-specificity).

-Pollination biology, insect behavior.
