Research

The mission of the Veterinary Entomology Laboratory is to investigate the ecological relationships between vertebrates and their ectoparasites and other arthropod pests to facilitate the development of control methods and integrated pest management strategies. We don't study a specific taxa or phenomenon but rather problems associated with non-human vertebrates. Of particular interest are filth flies affecting livestock, poultry, and equids and ticks and tick-borne disease ecology.
