Jeffrey L. Littlefield

Research Scientist; Ph.D., 1986 University of Wyoming; M.S. 1980, University of Idaho; B.S. & B.S.F. 1975, University of New Hampshire. Biological control of weeds, including the determination of host and habitat specificity, bionomics, insect-plant interactions, quarantine screening, and field release of potential biocontrol agents.
