Abstract
Cottontail rabbits, S. floridanus (24% of 2643), collected in Virginia [USA] from 1949-1975 showed evidence of Cuterebra parasitism. Occurrence was seasonal with greatest prevalence from July to Nov. Some Oryctolagus cuniculus, S. palustris and one S. transitionalis also showed Cuterebra myiasis. Juvenile rabbits had higher infection rates (28%) than did adult rabbits (14.5%, P < .001). Juveniles had greater numbers of larvae per host than adults, with means of 2.14 and 1.62, respectively. Larval development sites were in the genital region of most hosts. Twenty flies reared from wild cottontails were identified as C. buccata. Duration of induced infections in Oryctalagus was 30-33 days. Minimal generation time for C. buccata was 11 wk, allowing up to 4 generations of flies to occur annually in the southern and 1 generation to occur in the northern distributional limits of this bot fly. Peromyscus hosts were refractory to C. buccata infections. C. buccata fecundity averaged 1316 eggs. Field observations of adult flies are described.This publication has 0 references indexed in Scilit:
