Abstract:The growth of larvae of Cochliomyia hominivorax (Coquerel) in fresh wounds on sheep occurred in 3 phases. The lst phase (initial growth) was characterized by a slow increase in weight (from 0.3 to 11 mg) and was terminated after about 84 hours of feeding. The 2nd phase (critical growth) was characterized by attainment of the weight necessary for successful pupation (about 35-65 mg) and was terminated at about 120 hours after infestation, The third phase (postcritical growth) was characterized by an additional increase in weight beyond the critical weight that determined the size of the subsequent adult body; it was terminated by the migration of the larva from the wound (168-196 hours after infestation). Female flies from larvae weighing less than 40 rug after about 96 hours of feeding were frequently delayed in or were incapable of maturing eggs, However, the percentage with retarded ovarian development declined among flies from larvae weighing more than 56 mg after about 96 hours of feeding.
