“…The heavier body of instar V nymphs and adult P. nigrispinus when fed T. molitor is important because heavier individuals have better reproductive success (De Bortoli et al 2016;Lemos et al 2003). Podisus nigrispinus females were heavier than the males, which is consistent with reports of adult weights from 45 to 140 mg for females and 35 to 100 mg for males (Torres et al 2006), and independent of diet (Lemos et al 2001(Lemos et al , 2003.…”

“…In more advanced instars of both predators, a greater predation capacity was observed for eggs. This was expected, given that the older the insect, the greater its food requirements (Bortoli et al, 2016;Cruz et al, 1995;Mendes and Bueno, 2001;Mendes et al, 2003;Oliveira et al, 2008;Reis et al, 1988).…”

Understanding the ecological and toxicological relationship between genetically modified cultivars (GM) and biological control agents is of great importance for discussions related to the compatability of GM cultivars and integrated management strategies for pest resistance. The present study evaluated the search behavior and predatory capacity of Orius insidiosus (Say) (Hemiptera: Anthocoridae) and Doru luteipes (Scudder) (Dermaptera: Forficulidae) on eggs and caterpillars of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) resistant or not to the protein Cry1F expressed in Bt corn. To determine the search time, a stopwatch was run until the capture of the first prey, predation capacity was evaluated by counting the prey remaining after 24 hours of infestation. The injuries of S. frugiperda in genetically modified and conventional corn in the presence and absence of predators was also evaluated. The predators were not able to distinguish between resistant and susceptible prey (eggs or caterpillars), given the predatory behaviour observed. There was no difference in searching time or predatory capacity between the predators for eggs and caterpillars of either resistant or susceptible S. frugiperda. In the presence of predators, the injury scores for resistant S. frugiperda on the Bt corn plants were lower. It was concluded that O. insidiosus and D. luteipes did not notice the presence of the protein Cry1F in the prey S. frugiperda, which may facilitate the combined use of GM corn and biological control in integrated management programs and for management of pest resistance. ResumoO entendimento de relações ecológicas e toxicológicas envolvendo culturas geneticamente modificadas (GM) e agentes de controle biológico é de grande importância para discussões relativas à compatibilidade de culturas GM com estratégias de manejo integrado e manejo de resistência de pragas. Este trabalho avaliou o comportamento de busca e a capacidade predatória de Orius insidiosus (Say) (Hemiptera: Anthocoridae) e Doru luteipes (Scudder) (Dermaptera: Forficulidae) sobre ovos e lagartas de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) resistente ou não à proteína Cry1F expressa em milho Bt. Para determinar o tempo de busca foi utilizado um cronômetro que foi disparado até a captura da primeira presa; a capacidade de predação foi avaliada através da contagem das presas remanescentes 24 h após infestação. Também foram avaliadas as injúrias de S. frugiperda em milho transgênico e milho convencional na presença ou ausência dos predadores. Os predadores não foram capazes de distinguir entre presas (ovos ou lagartas) resistentes e suscetíveis, considerando os comportamentos predatórios avaliados. Não houve diferença no tempo de busca e capacidade predatória sobre ovos e lagartas de S. frugiperda resistente ou suscetível entre os predadores. Na presença dos predadores, as notas de injúria de S. frugiperda resistente nas plantas de milho Bt foram menores. Conclui-se que O. insidiosus e D. luteipes não percebem a presenç...

“…The greater mass of females is due to the accumulation of biomass necessary for the beginning of reproduction, since this parameter has been related to the development of their ovaries, as well as egg formation (Oliveira et al, 1999(Oliveira et al, , 2011. The predator's mass reflects its diet, that is, properly fed individuals gain more mass than those who eat less (O'Neil & Wiedenmann, 1990;Angelini & Boiça Junior, 2015;De Bortoli et al, 2016). Thus, it can be inferred that H. armigera confers adequate performance to the predator P. nigrispinus by providing greater body mass when compared to T. molitor.…”

Managing Helicoverpa armigera is still a major challenge for Brazilian farmers, due to limited information available about chemicals and biological control of this pest in Brazil. This study focused on evaluating the biological aspects of Podisus nigrispinus fed with H. armigera, under laboratory conditions, as well as verifying the capacity of the P. nigrispinus in preying on caterpillars of H. armigera in the field, in soybean crops. The experiments were conducted in laboratory under controlled temperature conditions of 25±2 ºC, relative humidity (RH) 60±10% and 14-hour photophase, as well as in the field, at the experimental station of Fundação MS in Maracaju, MS. In the laboratory, second instar nymphs of P. nigrispinus were placed in plastic jars and fed with H. armigera larvae or Tenebrio molitor larvae throughout the nymphal phase. When they reach adulthood, 15 couples were formed, remaining with the same prey of the previous phase. For the field trial, soybean plants were caged, and inside these cages were released eight quarter-instar H. armigera caterpillars. Subsequently, in each cage were released an adult female or a fifth instar nymph, and after 24 hours, the number of prey caterpillars were assessed. Predator nymphal duration was shorter in treatment with H. armigera than with T. molitor. Nymphal viability was similar between treatments. Adult females and males fed with H. armigera presented greater body mass than those fed with T. molitor. The number of postures per female and the number of eggs per female were similar between treatments. The incubation period of eggs was longer for treatment with H. armigera, differing statistically from treatment with T. molitor. Eggs from treatment with H. armigera showed similar viability to treatment with T. molitor, not differing statistically. Females and males under treatment with H. armigera showed longer longevity compared to treatment with T. molitor. Adult females preyed on average 2.26 caterpillars within 24 hours and fifth instar nymphs preyed on 1.73 caterpillars/day. P. nigrispinus showed better development when fed with H. armigera, demonstrating that it can be used as an alternative host for breeding this predator. The predator showed satisfactory performance for predation rate/day. Release of fifth instar nymphs and adult females of P. nigrispinus may reduce the pest population in relation to the absence of the predator under field conditions, an important alternative to be used in H. armigera integrated management programs.
