Entomology (Biological Control) (60% Research / 20% Extension / 20% Teaching)


Dr. Frank conducts research, teaching, and extension in biological control.  Dr. Frank serves as the coordinator of UF/IFAS mole cricket research program and his current projects are against Scapteriscus mole crickets (pests of turf, pasture grasses, and vegetables), biological control of pest insects using parasitoids, predators, or pathogens, and Metamasius callizona (pest of bromeliads).  Current extension responsibilities are partially on biological control of mole crickets in forage grasses and turf.
