ABSTRACT
Males behavioral, morphological, and physiological characteristics have been considered important to the females’ reproductive success and the quality of their offspring. Thus, the present study investigated the effect of the size and previous mating status of predatory stinkbug Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) males on offspring development. Two male body-size classes: small, < 40 mg and; large, > 50 mg; and the males’ mating status: virgin and previously mated males were investigated. Mated males were considered with 4 copulas within 15 days interval. The results show that male mating status presented a significant effect on offspring performance based on the second egg batch produced. Females mated with virgin males produced a higher number of eggs and nymphs, and larger eggs. Also, nymphs originated from the second egg batch by females mated with virgin males developed faster and achieved higher viability. Thus, based on these results the development of the offspring is related to the mating status of males.
