Abstract

A general description of the life stages and population parameters of Catolaccus hunteri Crawford, a primary ectoparasitoid of pepper weevil, Anthonomus eugenii Cano, and boll weevil, Anthonomus grandis grandis Boheman, is presented. The parasitoids were reared on the unnatural host Callosobruchus maculatus F. The developmental time of C. hunteri at 27 ± 1°C was shorter in males than females. Males completed development in 11.46 ± 0.46 d from egg to adult emergence. Developmental time in females required 13.18 ± 0.81 d from egg to adult at the same temperature. A C. hunteri female (n = 20) laid 466.35 ± 280.39 eggs, of which just 18.35% reached the adult stage; this could be the result of cannibalistic larval behavior combined with high superparasitism observed under laboratory conditions. Female mean longevity was 47.20 ± 12.76 d. The net reproductive rate (Ro), the generation time (G), and the daily intrinsic rate of increase (rm) were 42.713, 33.842, and 0.111, respectively. The fecundity of pepper weevil and boll weevil is discussed.
