“…Moreover, the mating period allowed was four hours, which is longer than that observed in other studies. The lack of mating in P. nigrispinus was identified by several movements without a defined behavioral sequence and by periods of immobility, both of which have been previously reported for both sexes in other species of Asopinae before either copulation (Carvalho et al, 1995) or predation (Lemos et al, 2005a).…”

Sexual choice by male stink bugs is important because females that experience food shortages lay fewer eggs with lower viability compared with well-fed females. In this study, we investigated whether Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) males fed with a low-quality diet during its nymphal stage show selectivity for sexual partners resulting in high-quality progeny. Lightweight males and females were obtained from nymphs fed weekly with Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae. By contrast, heavyweight males and females were fed three times a week and received an extra nutritional source: cotton leaves, Gossypium hirsutum L. (Malvaceae). Lightweight males preferred to mate with heavy females (77.78 ± 14.69%), whereas heavyweight males did not discriminated between light or heavyweight females. Females mated with lightweight males showed similar levels of reproduction to those mated with heavyweight males. The results provide an indication of the importance of male and female body weight for sexual selection in Asopinae stink bugs.Keywords: body weight, reproductive success, stink bug, predation, sexual selection. Machos leves de Podisus nigrispinus (Heteroptera: Pentatomidae) negligenciam fêmeas leves devido ao baixo desempenho reprodutivo ResumoA seleção sexual por machos de percevejos é importante porque fêmeas que passaram por escassez alimentar poem poucos ovos com baixa viabilidade em comparação com fêmeas bem alimentadas. Nesse estudo, investigamos se machos de Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) alimentados com dieta de baixa qualidade durante seu estágio ninfal apresenta seletividade por parceiras sexuais resultando em progênie de alta qualidade. Machos e fêmeas leves foram obtidos de ninfas alimentadas semanalmente com pupas de Tenebrio molitor L. (Coleoptera: Tenebrionidae). Em contraste, machos e fêmeas pesados foram alimentados três vezes por semana e receberam uma fonte nutricional extra: folhas de algodão, Gossypium hirsutum L. (Malvaceae). Machos leves preferiram acasalar com fêmeas pesadas (77,78 ± 14,69%), enquanto machos pesados não distinguiram fêmeas leves ou pesadas para acasalamento. Fêmeas que acasalaram com machos leves apresentaram níveis de reprodução semelhantes em comparação com aquelas acasaladas com machos pesados. Os resultados fornecem uma indicação da importância do peso corpóreo de machos e fêmeas para a seleção sexual em percevejos Asopinae.Palavras-chave: peso corpóreo, sucesso reprodutivo, percevejo, predação, seleção sexual.

“…We recorded individual's attack behaviors for 2 h with uninterrupted direct observation or a digital video camera (NV-GS320; Panasonic, Tokyo, Japan). We recorded the following predator behaviors: (1) touch: light contact on the prey with its antennae or other parts of its body; (2) attack: insertion of stylets into the prey body; (3) prey paralysis: immobilization of the prey after insertion of its stylets; and (4) retreats: the predator retreats after defensive movements of the prey (Lemos et al 2005). We recorded the number of successful attacks as the number that led to prey paralysis.…”

Group predation promotes foraging efficiency because it increases the size of prey that can be killed and improves hunting success compared to solitary predation. However, group predation may increase competition among group members during feeding. Earlier studies have focused on the advantages of group predation, but little is known about the costs and benefits of group predation for individual members of the group. Here, we show that the costs and benefits of group predation for individuals of the predatory stink bug Andrallus spinidens vary with prey size in laboratory experiments. We found that when A. spinidens fed on small prey, group predation did not significantly increase foraging efficiency but did increase competition for food among group members. In contrast, when prey was large, group predation promoted foraging efficiency, and competition over food was not detected. Our results suggest that group predation by A. spinidens nymphs is advantageous for individual members because it enables each member to hunt larger prey that could not be hunted alone. However, when group size was large or prey size was small, group predation increased competition among group members.

“…For this reason, these natural enemies act as agents for the evolution of the prey by selecting stronger and vigorous individuals. On the other hand, the predators develop more efficient techniques to attack their preys (Azevedo and Ramalho, 1999a, b;Lemos et al, 2005). Factors such as the densities of the prey and predators, environmental conditions, mechanisms of prey defense and strategies of attack of the predator can interfere in the predation process (Holling, 1959).…”
