Abstract
Egg viability and nymphal development of the predatory bug Supputius cincticeps (Stal, 1860) were evaluated during two generations in the Biological Control Laboratory of the Nucleo de Biotecnologia Aplicada a Agropecuaria (Bioagro/UFV) in Vicosa (Minas Gerais, Brazil) at 24.72±1.10oC and photophase of 12 hours. Three treatments were represented by S. cincticeps fed with Zophobas confusa Gebien, 1906, Tenebrio molitor Linnaeus, 1758 and Musca domestica Linnaeus, 1758 larvae. Higher egg viability of this predator was found when the preys were Z. confusa and T. molitor, 74.46% and 80.91 %, than in M. domestica, 57.02%, but incubation period showed no differences between preys. Shorter nymphal development and higher nymphal viability were found with Z. confusa and T. molitor than with M. domestica. Higher weight increase was found for nymphs which originated males and females in the second generation specialy with the first two preys.
