Abstract: The sea lamprey is an ancient vertebrate - one of the oldest - with a fascinating history. The chapter covering the last century reveals its decimating effect on the fisheries of the Great Lakes, where it thrives as an invasive pest. Current sea lamprey control programs there rely heavily on the use of a larvicide (TFM). Various multidisciplinary, collaborative studies between researchers in my laboratory and those of Professors Peter Sorensen1-3 (Department of Fisheries, Wildlife, and Conservation Biology; University of Minnesota) and, more recently, Weiming Li4-5 (Department of Fisheries and Wildlife and the Department of Physiology; Michigan State University) have led to the discovery of various chemical compounds that are emitted by larvae and elicit olfactory responses in adults. Some induce conspecific behavioral activity, marking them as components of lamprey pheromones. It is alluring to consider the possibility of using migratory pheromones for the development of alternative and environmentally benign lamprey control strategies. Aspects of the biology and chemistry that drive these sorts of studies will be presented.

Speaker Bio: Thomas R. Hoye attended Bucknell University where research experiences in heterocyclic chemistry in the laboratories of Professor Harold W. Heine convinced him to lay aside study of chemical engineering to concentrate on organic chemistry. He completed the B.S./M.S. degrees in 1972 and proceeded to graduate studies in the laboratory of Professor Robert B. Woodward at Harvard University, earning the Ph.D. degree in 1976. That fall he joined the faculty in the Department of Chemistry at the University of Minnesota, where he has spent his independent career leading a research program in synthetic and mechanistic organic and polymer chemistries.
