Description
En Minas Gerais, Brasil, se estudió el desarrollo ninfal y la reproducción de Supputius cincticeps (Heteroptera: Pentatomidae), comparando alimentación en dieta artificial y alimentación con larvas de Tenebrio molitor (Coleoptera: Tenebrionidae), a 25±20C, 60 ± 10% de humedad relativa y 12 h de fotofase. La dieta artificial estaba constituida de: hígado de res (60 g), carne de res con 15% de grasa (60 g), solución a 5% de sacarosa (15 mI), levadura de cerveza (3 g). yema de huevo (12 g), miel (7.2 g), sales de Wesson (0.6 g), ácido ascórbico (0.3 g), nipagin (0.3 g) y tetraciclina (0.03 g). Los ingredientes fueron licuados hasta la formación de una pasta que fue envuelta en Parafilm-M en forma de larvas artificiales de 2 X 3 cm. El experimento fue iniciado con treinta individuos por tratamiento, individualizados en placas Petri de 90 X 15 mm. La dieta artificial permitió el desarrollo ninfal y la reproducción de S. cincticeps durante dos generaciones, aunque el testigo presentó menor período ninfal, mayor peso de adultos, mayor viabilidad de huevos y mayor número de ninfas.
Nymphal and adult development of Supputius cincticeps (Heteroptera: Pentatomidae) was studied during two generations on an artificial diet in. Minas Gerais, Brazil. It was fed with Tenebrio motilor (Coleoptera: Tenebrionidae) pupae at 25±2oC, relative humidity of 60±10% and photophase of 12 hours. The diet consisted of beef Iiver (60 g), beef meat with aproximately 15% of fa! (60g), sucrose solution at 5% ( 15 mI), beer yeast (3 g), egg yolk ( 12 g), honey (7.2 g), Wesson salt (0.6 g), ascorbic acid (0.4 g), nipagin (0.3 g) and tetraciclin (0.03 g). These ingredients were liquefied to produce a paste which wa, wrapped in Parafilm-M to mould artificial "caterpillars" of 2 X 3 cm. This experiment was initiated with 30 nymphs in each treatment reared individually in Petri dishes with a diameter of 90 x 15 mm. S. cincticeps completed its nymphal and adult development with this diet but the insects reared with T. molitor pupae produced a shorter nymphal period, heayier adults, higher egg viability and more nymphs.
