An attempt was made to quantify the influence of prey scarcity on longevity and on the reproductive variables of females of the predatorPodisus nigrispinus (Dallas) (Heteroptera: Pentatomidae). The predators received prey (Alabama argillacea) of different sizes,viz., 50 mg (small prey) or 220 mg (large prey), for a period of 24 h, daily or every 2, 4, 8 or(More)
The food extraction by adult females ofPodisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) from 3 rd instarAlabama argillacea (Hübner) larvae was evaluated in the laboratory. The densities studied were converted to weight of prey offered: 15.7 (one larva); 44.1 (three larvae); 71.4 (five larvae); 117.4 (seven larvae) and 148.8 mg (nine larvae). The(More)
