Longevity and survival of the predator Podisus connexivus (Hemiptera: Pentatomidae) were studied in three alternative preys: T1 - Bombyx mori (Lepidoptera, Bombycidae) catterpilars; T2 - Musca domestica (Diptera, Muscidae) larva and T3 - Tenebrio molitor (Coleoptera, Tenebrionidae) larva. Longevity and survival were: 22,1±0,6 days and 54,3±5,3%; 25,2±1,3 days and 56,0±4,9% and 22,0±0,8 days and 34,6±8,6%, for treatments T1, T2 and T3, respectively. Comparing to other researches, a lower survival was found. This is probably because a F2 generation from field material, was used. Since the insect was not well adapted to the laboratory conditions this could have led to lower survival.
