| Podisus nigrispinus is a generalist predator naturally occurring in agricultural and forestry systems that effectively contributes to the population balance of phytophagous insects, especially defoliating caterpillars. Histological changes were evaluated in the salivary glands and midgut of P. nigrispinus caused by ingestion of systemic herbicide isoxaflutole. These predator females were fed with leaves of eucalyptus plants, Tenebrio molitor pupae or water, contaminated or not by herbicide. Salivary glands and midguts were dissected, processed and analyzed under a light microscope. Activity level and cell morphology of the salivary glands and midgut showed differences among insects fed on plants, contaminated water or pupae. The epithelia of the salivary... |

| The effect of temperature on the development of Podisus nigrispinus (Dallas, 1851) and Supputius cinctceps (Stål, 1860) was studied in order to adjust equations to predict the development of these predators under 18, 20, 25, 30, 32 and 35º±0.2ºC, relative humidity of 65±10% and photophase of 12 hours. Incubation period of the eggs and duration and viability of nymphal stage were quadratically influenced by temperature while egg viability decreased linearly with increased temperature. The best temperature for egg development was 29ºC for both species and for nymphal development of P. nigrispinus and S. cincticeps they were 29º and 28ºC respectivelly. Nymphal viability was highly affected by extreme temperatures, with optima around 24ºC for S. cincticeps and... |
