| In this work, the effect of different densities (1, 3, 5, 7 and 9) of 3rd instar Alabama argillacea (Huebner) larvae on food consumption by Podisus nigrispinus (Dallas) males was evaluated. The densities established were converted to weight of prey offered: 13.4 mg (one larva), 33.3 mg (three larvae), 54.3 mg (five larvae), 81.8 mg (seven larvae), and 110.34 mg (nine larvae). The quantity of food consumed by P. nigrispinus increased with the prey density. The density of preys did not affect the time spent by the predator to ingest the food. The quantity of food extracted per minute was always higher in smaller densities and lower in higher densities. Males mean body weight did not differ statistically between the treatments tested, and weight gain was... |

| The aim of this study was to evaluate the development and reproduction of P. nigrispinus in laboratory when fed with T. arnobia reared on guava leaves. This predator showed nymphal stage of 21.11 days, survival of 60% and periods of pre-oviposition, number of eggs/mass and eggs/female and egg viability of 6.10 days, 26.24 eggs, 314.90 eggs and 82.65%, respectively. These results demonstrated that T. arnobia fed with guava leaves was an adequate supply of food to P.nigrispinus. |
