RESUMO
Development and reproductive performance of Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) fed with Musca domestica L. (Diptera: Muscidae) larvae was evaluated. Duration of the nymphal phase of this predator was 31.2 days, with a 44.1 percent survival rate. Preoviposition and egg incubation periods and number of eggs/egg mass were 8.14 days, 5.6 days, and 45.4, respectively. B. tabidus presented 44.7 percent egg viability. Female longevity of this predator was 18.4 days. Results are discussed based on this prey use in mass rearing and maintenance of colonies of B. tabidus under laboratory conditions.

A performance reprodutiva e o desenvolvimento de Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) alimentado com larvas de Musca domestica L. (Diptera: Muscidae) foram investigados. A duração da fase ninfal desse predador foi de 31,2 dias, com sobrevivência de 44,1%. Os períodos de pré-oviposição e de incubação e o número de ovos por postura foram de 8,14 dias, 5,6 dias e 45,4 dias, respectivamente. B. tabidus apresentou viabilidade de ovos de 44,7%. A longevidade das fêmeas desse predador foi de 18,4 dias. Esses resultados são discutidos com ênfase ao uso de M. domestica em criação massal e manutenção de colônias de B. tabidus em condições de laboratório.
