Abstract

Cuterebra jellisoni Curran was colonized in the laboratory. Mating was induced by the tethering method. Infective larvae were introduced via natural body openings into black-tailed jackrabbits (Lepus californicus ) , mountain cottontail rabbits (Sylvilagus nuttalli) , pigmy rabbits (Sylvilagus idahoensis) , domestic rabbits (Oryctolagus cuniculus) , deer mice (Peromyscus maniculatus) , and laboratory mice (Mus musculus). Host specificity was demonstrated in favor of the native host species. Lepus californicus. However, all lagomorph species tested supported larvae to maturity. Infections in Sylvilagus and Oryctolagus were less successful than in Lepus. Rodents were refractory. Terminal development of larvae in lagomorph hosts varied between host species but averaged 35 days. The larvae demonstrated strong preference for development sites on the head. Adult flies emerged from puparia in 125 days.
