“…Zanuncio et al (2000) recommended to rear the stinkbug Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) with prey and seedlings of Eucalyptus in order to reduce nymphal mortality and to increase adult longevity and number of eggs and nymphs produced per female of this predator. Therefore, these results suggest that pentatomid predators can obtain nutrients from plants, as well as from prey which agree with reports of other authors (Valicente & O'Neil, 1995;Lemos et al, 2001).…”

-Considering the importance of predatory Pentatomidae as biological control agents it is necessary to optimize mass production facilities of these species. The objective of this research was to evaluate the influence of body weight on survival and reproductive parameters of females of Podisus rostralis (Stål) (Hemiptera: Pentatomidae). Treatments were represented by females of this predator with the following mean weight: 39.5 mg, 45.5 mg, 51.5 mg, 57.5 mg and 63.5 mg. Heavier females of P. rostralis showed shorter preoviposition period while the number of eggs and of nymphs per day presented a positive linear relationship with female weight of this predator. Longevity of females of P. rostralis was similar between treatments with no tendency of variations as a function of body weight of these females. Since the objective of mass rearing facilities of predatory bugs is to produce the maximum possible number of nymphs per day it is recommended to use females of P. rostralis with weight above 60.0 mg.Index terms: biological control, mass rearing, reproductive performance, survival. Efeito do peso corporal na fecundidade e na longevidade do percevejo predador Podisus rostralisResumo -Considerando a importância dos percevejos predadores como agentes de controle biológico e a necessidade de se otimizar sua produção massal, realizou-se o presente trabalho para avaliar a influência do peso corporal sobre a sobrevivência e a reprodução de fêmeas de Podisus rostralis (Stål) (Hemiptera: Pentatomidae). Os tratamentos foram constituídos por fêmeas desse predador com peso médio de: 39,5 mg, 45,5 mg, 51,5 mg, 57,5 mg e 63,5 mg. O período de preoviposição foi menor nas fêmeas mais pesadas, enquanto o número de ovos e de ninfas por dia apresentou relação linear positiva com o peso das fêmeas de P. rostralis. A longevidade das fêmeas desse predador foi semelhante entre tratamentos, porém não apresentou tendência de variação em razão do seu peso corporal. Como o objetivo de uma criação massal é produzir o maior número possível de ninfas por dia, recomenda-se o uso de fêmeas de P. rostralis com peso acima de 60,0 mg. Termos para indexação: controle biológico, criação massal, desempenho reprodutivo, sobrevivência.

“…In the field, plant-derived substances can be an alternative or complementing the diet of predatory bugs (Crum et al, 1998), allowing them to maintain their longevity (Valicente and O'Neil, 1995;Zanuncio et al, 2004). The use of plants as dietary supplement may or may not lead to a better establishment of predatory bug populations, depending on the composition of the agroecosystems .…”

“…The prey availability and quality can influence the development of P. nigrispinus (Valicente and O'Neil 1993;De Clercq et al, 1998;Molina-Rugama et al, 1998a;Mourão et al, 2003). However, this predator can also feed on plants without damaging them (Naranjo and Stimac, 1985;Ruberson et al, 1986;Naranjo and Stimac, 1987;De Clercq and Degheele, 1992;Lemos et al, 2001).…”

The purpose of this study was to investigate the development and reproduction of the zoophytophagous predator Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) fed kale, broccoli and cabbage affects its. Nymphs and adults of this predator were fed on larvae of Plutella xylostella (L.) (Lepidoptera: Plutellidae) as prey with kale, cabbage, or broccoli. In the nymph period, the duration and prey consumption were similar with all the Brassicacea cultivar. However, nymph viability was higher for predators with broccoli leaves. The mean weight of 5 th -instar nymphs, newly emerged females and the sex ratio were similar among the Brassicacea cultivars, while newly emerged males were heavier with kale and broccoli leaves. The supply of broccoli leaves resulted in greater oviposition, higher number of eggs per egg mass and longer longevity of P. nigrispinus males and females. Furthermore, the consumption of P. xylostella larvae by adult predators was higher with these cultivars. The net reproductive rate (R 0 ) and mean generation time (T) were highest for predators with prey and broccoli leaves. The reproductive parameters of P. nigrispinus were enhanced when fed on P. xylostella larvae with and broccoli leaves, which can be an alternative diet in laboratory rearing of this predator.Keywords: biological control, mass rearing, predatory stinkbug, zoophytophagous.Fitofagia do predador Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) em diferentes brassicáceas Resumo O objetivo deste estudo foi verificar o desenvolvimento e reprodução do zoofitófago Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) em couve, brócolis e repolho. Ninfas e adultos deste predador foram alimentados com lagartas de Plutella xylostella (L.) (Lepidoptera: Plutellidae) como presa e receberam folhas de couve, repolho ou brócolis. Durante o período ninfal, a duração do período e o consumo de presas foram semelhantes com as diferentes cultivares de brassicácea. Porém, a viabilidade ninfal foi maior para predadores com folhas de brócolis. O peso de ninfas de quinto instar e de fêmeas recém-emergidas e a razão sexual de P. nigrispinus foram semelhantes entre as cultivares de brassicáceas, enquanto que o peso de machos recém-emergidos foi maior com folhas de couve e brócolis. Folhas de brócolis proporcionaram maiores número de oviposições, ovos por postura e longevidade de machos e fêmeas de P. nigrispinus. Além disso, o consumo de lagartas de P. xylostella por adultos desse predador fora maiores com esta cultivar. A taxa líquida de reprodução (R 0 ) e o tempo médio de geração (T) foram maiores para predadores com presa e folhas de brócolis. Podisus nigrispinus alimentados com lagartas de P. xylostella e folhas de brócolis apresentaram melhores parâmetros reprodutivos, podendo ser uma alternativa para a criação deste predador em laboratório.Palavras-chave: controle biológico, criação massal, percevejo predador, zoofitófago.

“…Likewise, Dicyphus hesperus Knight (Miridae), although considered a biological control agent, can switch its diet on greenhouse whiteflies and tomato plants, and when provided a diet consisting only of prey, they exhibit very low survival (Gillespie and McGregor, 2000). Predatory hemipterans, having access to plant materials, exhibit greater survival, larger body weight, greater fecundity, and live longer, and shorter developmental time (Stoner, 1970;Naranjo and Stimac, 1985;Ruberson et al, 1986;Valicente and O'Neil, 1995;Oliveira et al, 2002;Evangelista et al, 2004). Those species exhibiting improved life history traits might benefit as a result of acquiring extra sources of nutrients and steroids, such as campesterol, for synthetizing molting hormones (Thummel and Chory, 2002).…”

“…Campesterol is found in plants, especially in the legume family. Legumes are known hosts for phytophagous hemipterans and provide the best results as supplementary food for predaceous hemipterans (Valicente and O'Neil, 1995;Coll, 1998;Evangelista et al, 2004). Under this scenario, predatory hemipterans presumably ingest certain nutrients or hormones derived from plants which they cannot derive from prey.…”
