“…O número de ovos por fêmea de P. nigrispinus, em todos os tratamentos, foi superior aos valores observados em outros trabalhos que utilizaram essa mesma presa (Oliveira et al, 2004;Freitas et al, 2006;De Bortoli et al, 2011). O maior número de ovos por fêmea com o farelo de trigo pode ser devido ao desenvolvimento diferenciado dos ovários desse predador, em relação à dieta da presa consumida (Lemos et al, 2005). Segundo esses autores, fêmeas de P. nigrispinus alimentadas com dieta artificial apresentaram menor período de oviposição, menor número de posturas, ovos por postura e número de ovos por fêmea.…”

Inimigos naturais são importantes para o controle de pragas em culturas agrícolas e florestais. A criação de insetos predadores em biofábricas deve ser de baixo custo para serem utilizados em programas de Manejo Integrado de Pragas (MIP). O objetivo deste trabalho foi avaliar o desenvolvimento de Podisus nigrispinus Dallas, 1851 (Heteroptera: Pentatomidae), alimentado com larvas de Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae), criadas com as seguintes dietas: farelo de trigo, ração triturada ou peletizada para aves poedeiras e fubá de milho. Foram obtidos os parâmetros de desenvolvimento e reprodução necessários para calcular a tabela de vida do predador. Os parâmetros da tabela de vida revelaram crescimento populacional em todos os tratamentos. No entanto, a taxa líquida de reprodução (Ro) de P. nigrispinus foi menor quando alimentados com larvas de T. molitor criadas com fubá de milho, mostrando ser a alimentação menos adequada para esse predador. Por proporcionar maior número total de ovos, o farelo de trigo constituiu a melhor dieta para P. nigrispinus. Estudos sobre dietas de presas alternativas são importantes, pois podem favorecer a nutrição de inimigos naturais e, consequentemente, melhorar o desempenho das criações massais em laboratório.

“…Pentatomid predators are important to control defoliating caterpillars and other insects (Torres et al, 2006), mainly because they can survive even during prey scarcity (Evangelista Junior et al, 2004). The predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: (Lemos et al, 2005). Mass rearing P. nigrispinus requires alternative prey (Vacari et al, 2007) due to the difficulty of rearing natural prey in the laboratory, but P. nigrispinus performs better with lepidopteran prey (Oliveira et al, 2004a).…”

Mass production of predatory stinkbugs in the laboratory is prioritized to release them into the field as part of IPM programs. Therefore, the aim of this study was to identify the best prey for rearing the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) among five different species of insect (three of Lepidoptera, one of Coleoptera, and one of Diptera). Second-instar P. nigrispinus nymphs were conditioned in transparent 1000-mL plastic pots, adults were placed in Petri dishes for mating, and both stages were maintained under controlled conditions (25 ± 1°C, 12 hours of photophase, 70 ± 10% RH). Nymphs and adults of P. nigrispinus consumed more Musca domestica (Linnaeus, 1758) (Diptera: Muscidae) larvae than the other tested prey. The consumption of fly larvae was 1.5 larvae/day/nymph and adults 1.7 larvae/day/adult. However, the number of eggs per female was less when the predator consumed M. domestica larvae (407.8 eggs/female) and most when consumed the Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) larvae (797.7 eggs/female). Furthermore, the percentage of hatched eggs was greater when the predator females consumed D. saccharalis larvae (90.0%). D. saccharalis larvae is the best prey to rearing P. nigrispinus.

Problem statement: Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) is a common and important species for the biological control of defoliating Lepidoptera caterpillars. Although it has a predatory feeding habit, this species make use of plant resources, which are essential for the maintenance of its population in laboratory colonies as well as in the field during periods of prey shortage. Thus B. tabidus has been considered an obligate zoophytophagous insect. However the impact of the age and herbivory on the morphology of the reproductive organs has been poorly studied in predatory Pentatomidae. The morphology of the reproductive tract of B. tabidus males with different ages and fed on different diets were analyzed. Approach: Nymphs of B. tabidus were maintained in the field with or without plants and fed on T. molitor pupae without plant (T 1 ); T. molitor pupae and Eucalyptus cloeziana plants (T 2 ); T. molitor pupae and Eucalyptus urophylla plants (T 3 ) or T. molitor pupae and guava plants (Psidium guajava L.) (T 4 ). Adults of B. tabidus obtained from each treatment were sexed in the first day of their emergence and thirty-six pairs were formed per treatment. Ten males of B. tabidus 15 and 21 days old, obtained in each treatment were dissected and the reproductive tract submitted to histological analyses. The total area of the testes of B. tabidus was measured and the data were submitted to the variance analysis and means between treatments were compared by the test of Newman-Keuls (p = 0.05). Results: The inner genitalia of B. tabidus males had red color and the testes with six follicles. Males 15 days old presented larger testes when fed on E. cloeziana (0.94 mm 2 ), E. urophylla (0.98 mm 2 ) or only T. molitor pupae (0.99 mm 2 ) than with guava plants (0.76 mm 2 ). Twenty-one days old B. tabidus males presented testes with similar size, independent of the diet. The testes follicles of B. tabidus had larger amount of spermatozoa with all diets and ages showing that the spermatogenesis process was completed. The testes of this predator showed similar histological characteristics with all diets. Conclusion: The herbivory change the morphology of the reproductive tract of B. tabidus males in field conditions resulting in testes with different sizes, but it does not affect the histology of the reproductive organ of this predator. Therefore, the food type supplied to B. tabidus males does not affect the spermatogenesis process in this natural enemy.
