“…The number of testicular follicles varies from four to six. It is different from those found in other Heteropterans (Davis, 1955;Pendergrast, 1956;Chapman, 1998;Lemos et al, 2005;Pires et al, 2007;Rodrigues Agna et al, 2008). Testicular follicles of D. baccarum are lined by a layer of cells (peritoneal sheath), an epithelial sheath, and a non-cellular layer (tunica propria) (Figs.…”

“…The internal reproductive morphology of some Pentatomids, Nezara virudula (Linnaeus, 1758) (Pendergrast, 1956;Ramamurty, 1969), Chrysocoris stolli Wolf. (Singh, 1968), Perillus bioculatus (Fabricius, 1775) (Adams, 2001), Oebalus poecilus (Dallas, 1851) (Santos et al, 2003), Podisus nigrispinus (Dallas, 1851) (Lemos et al, 2005;Rodrigues Agna et al, 2008) have been the subject of detailed studies with emphasis on function. Morphologically, the male reproductive system consists of paired testes which each containing a series of testicular tubes or follicles (in which spermatozoa are produced).…”

“…A diversifi cação de cópulas por fêmeas de P. nigrispinus e outros pentatomídeos , McLain 1992 pode resultar em ganho genético para as fêmeas por permitir a heterogeneidade dos descendentes (Thornhill & Alcock 1983). Além disso, múltiplas cópulas são necessárias para a manutenção do estoque de espermatozóides em P. nigrispinus (Rodrigues et al 2008).…”

“…Fêmeas do percevejo predador Podisus nigrispinus (Dallas) realizam múltiplas e longas cópulas (Torres et al 1997, Rodrigues et al 2008, sendo a longevidade das fêmeas reduzida com o aumento no número de cópulas (Torres et al 1997, Sousa-Souto et al 2006. Consequentemente, fêmeas que acasalam com menor frequência são mais fecundas, produzindo, em média, 150 ovos a mais do que fêmeas continuamente acasaladas (Torres et al 1997).…”

“…Copulation by Nezara viridula (L.) (Heteroptera: Pentatomidae) was longer in the presence of more than one male (McLain, 1980). Longer copulations by P. nigrispinus were attributed to the protracted movement of the aedeagus to reach the spermatheca and release the sperm, rather than the length of copulation acting as a guarding behavior (Rodrigues et al, 2008). However, the production of polymorphic sexual cells by P. nigrispinus males suggests that there are distinct functions to these cells and indicates the evolutionary importance of intrasexual competition (Araújo et al, 2011).…”
