Feeding behavior can explain how predaceous Pentatomidae use different food sources as a result of ecological and evolutionary changes. This study describes the salivary glands of adults of the predator Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) to assist in understand the feeding habits of this natural enemy. A pair of principal and accessory glands in the prothorax form the salivary system of S. cincticeps. The principal glands are bilobed with a spherical anterior lobe and are smaller than the posterior lobe, which has a prolonged sack form. The accessory glands are present in a long and tubular form that arises from the terminal portion of the curved accessory duct. The salivary system of S. cincticeps presents the same morphological pattern of other Asopinae predators.

The development and survival of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) nymphs fed on larvae of Chlosyne lacinia saundersii Doubleday & Hewitson (Lepidoptera: Nymphalidae) was studied at 25 ± 1ºC, 68 ± 10% relative humidity and 12 h photo phase. P. nigrispinus developed until the adult stage when fed on C. lacinia saundersii caterpillars. However, the survival rate of P. nigrispinus during early instars allowed this predator to complement its diet with other preys and to maintain its populations in areas with the sunflower culture

potes plásticos até a fase de pupa. Dez casais desse lepidóptero foram individualizados em gaiolas para obtenção de ovos à temperatura de 25 ± 2 °C, umidade relativa de 60 ± 10% e fotofase de 12 horas. Halysidota pearsoni teve período de oviposição de 3,5 ± 0,17 com 141,00 ± 9,18 ovos por fêmea, período de incubação de 7,5 ± 0,17 dias e viabilidade de ovos de 53,34 ± 5,24%. A fase larval de H. pearsoni teve seis estádios, com duração total de 28 dias, viabilidade de 91,78 ± 3,24%. A duração e a viabilidade dos períodos pré-pupal e pupal de H. pearsoni foram, respectivamente, de 7,0 ± 00 e 19,39 ± 0,74 dias e de 70,15 ± 5,63 e 93,62 ± 3,60%. O peso médio de suas pupas foi de 464,17 ± 7,70 mg e a razão sexual e de 0,45. A longevidade (dias) de machos e fêmeas de H. pearsoni, com folhas de M. alba, foi de 7,40 ± 0,34 e 9,50 ± 0,45, respectivamente.Palavras chave: Insecta, biologia e Morus alba. 40 ± 0.34 and 9.50 ± 0.45, respectively.
