“…Possessing hairs or spines on the body is one of the major morphological defense mechanisms of some lepidoperan and coleopteran larvae against predation [30]. Our study showed that P. maculiventris significantly preferred to feed on smooth larvae over spiny or hairy prey.…”

Determination of feeding potential and prey acceptance of natural enemies is crucial to assure that natural enemies can control target pest species. This study was conducted to investigate feeding potential and prey acceptance of a generalist predator, Podisus maculiventris (Say) (Hemiptera: Pentatomidae). A series of laboratory experiments were conducted to quantify feeding potential of P. maculiventris by measuring daily feeding amount and to determine prey acceptance by analyzing feeding behavior of P. maculiventris on various types of prey. The result of this study showed that the amount of prey consumption differed significantly (F = 38.48; d.f. = 5, 44; P <0.05) among stages of P. maculiventris. P. maculiventris attempted to attack Halyomorpha halys (Hemiptera: Pentatomidae), but could not sustain effective feeding due to behavioral and chemical defense of the prey. P. maculiventris showed significantly (P < 0.05) less effective feeding on prey with spines or hairs such as Evergestis rimosalis (Lepidoptera: Crambidae) and Hyphantria cunea (Lepidoptera: Arctiidae). Utilization of P. maculiventris for controlling various types of pests for augmentative biological control is discussed in this article.

“…Development of P. maculiventris in the current study was slower and female weight and survival were higher than in previous studies using wax moth larvae as prey. Also, fecundities and oviposition periods were about half of those reported in earlier studies (De Clercq and Degheele, 1997;De Clercq et al, 1998b). Both developmental and reproductive traits may have been influenced by photoperiod: whereas in above mentioned studies long day conditions were used, the predator was currently reared at a 12:12 h photoperiod.…”

Effects of diet on development and reproduction of the predatory pentatomids Picromerus bidens and Podisus maculiventris

et al. 2006

The effects of five diets (larvae of Galleria mellonella L., larvae of Spodoptera littoralis (Boisduval), eggs of Ephestia kuehniella Zeller, cysts of Artemia franciscana Kellogg and an artificial diet based on bovine meat) on development, survival and reproduction of two predatory stinkbugs, Picromerus bidens L. and Podisus maculiventris (Say), were studied in the laboratory. Both species successfully completed immature development on the foods offered, except for P. bidens on cysts of A. franciscana. Significant effects of diet on developmental duration were found in both species. Total developmental time from second instar to adult ranged from 25.0 to 41.5 days and from 18.7 to 46.0 days in P. bidens and P. maculiventris, respectively. Nymphal survival of P. maculiventris was superior to that of P. bidens on all diets tested. Nymphal survival of P. maculiventris was greater than 92% on all diets except on A. franciscana cysts, yielding only 50% survival to adulthood. Survival of P. bidens fed on eggs of E. kuehniella was higher than that of conspecifics fed on caterpillar prey or artificial diet (89% on flour moth eggs vs. 68 and 80% on G. mellonella and S. littoralis and only 50% on meat diet). Fresh weight of newly emerged females of both pentatomids was affected by the diet offered to the predators during their nymphal stage. Females of P. maculiventris produced viable eggs on all diets except on cysts of A. franciscana and had mean fecundities of 691, 436, 608 and 344 eggs per female on S. littoralis, G. mellonella, E. kuehniella eggs and the meat diet, respectively. Females of P. bidens laid eggs only on live prey with mean fecundities of 94 and 38 eggs per female on S. littoralis and G. mellonella, respectively. The results indicate a lower nutritional plasticity of P. bidens as compared with P. maculiventris.

“…Lightweight females and males were those reared on the D1 diet, whereas heavyweight females and males were reared on the D2 diet. D1 represented a nutritionally incomplete diet (De Clercq and Degheele, 1992), whereas D2 represents a nutritionally complete diet according to Lemos et al (2003).…”

Lightweight males of Podisus nigrispinus (Heteroptera: Pentatomidae) neglect lightweight females due low reproductive fitness

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.
