Resumo: | The Asopinae insects are generalist predators, and Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is the most studied species of this group in Brazil. The objective was to study ovarian development, egg production and oviposition of mated and virgin P. nigrispinus females. Five 24-hours-old females were dissected and the ovaries were analyzed. Fifteen females of this predator were mated (T1), and another fifteen were individualized without mating (T2). The ovaries of five females per treatment were dissected and mature and immature eggs were counted. Five virgin females of P. nigrispinus at twenty days old were also analyzed. Twenty-four-hours-old P. nigrispinus females had low ovary development without the evidence of oocyte production. The females of the T1 had completely developed ovaries, with 22.67 ± 7.26 mature eggs and 31.33 ± 1.33 oocytes in the maturation process. Ovaries of females of T2 had a lower quantity of eggs in the early maturation stage (15 ± 1.73). Females of T2 that were dissected at day 20 had 28.33 ± 2.31 and 15 ± 1.96 mature and immature eggs, respectively. Podisus nigrispinus females begin oogenesis and egg maturation soon after their emergence but mating is important to maintain egg production and oviposition. |
