Tim Lysyk is a research scientist at Agriculture Canada's Lethbridge Research Centre. He works in entomology studying the ecology of flies and ticks that affect cattle. Tim holds a B.Sc. in Zoology from the University of Alberta and has an M.S. in Entomology from South Dakota State University and a Ph.D. in Medical-Veterinary Entomology from North Carolina State University. In addition to his research, Tim has also taught courses in entomology and ecology at the University of Lethbridge. Tim was recently awarded the Entomological Society of Canada's prestigious C. Gordon Hewitt Award for outstanding achievement in entomology by a person under 40.

Research Interests

General areas of interest are population ecology, quantitative ecology and physiological ecology. Current areas of research include developing life tables and analyzing demographic statistics of parasitic wasps for biological control; studies of development, diapause, survival and reproduction of insects of veterinary importance; and development of sampling methods and population models for integrated pest management of insects affecting cattle. Particular emphasis is placed on the horn fly, house fly and stable fly. Recently, I have developed an interest in ticks and tick-paralysis have started a research program to examine this trait in Dermacentor andersoni.
