“…The life cycle (25.96-33.57 d) and total viability (20-60%) of P. nigrispinus varied among cultivars (Table 2), with lower longevity, reproduction, and viability when predating on S. frugiperda, which had been fed genetically modified NuOpal (Lovei and Arpaia 2005, Lovei et al 2009, Cunha et al 2012). …”

“…Occasional prédation on prey fed on genetically modified plants can affect biological parameters, reduce fecundity, and delay oviposition in Ferillus bioculatus (F.) (Hemiptera: Pentatomidae), but did not affect adult mortality (Schüler et al 1999). Feeding P. nigrispinus on S. frugiperda reared on Acala 90 (Monsanto, Brazil) genetically modified cotton expressing the CrylAC toxin negatively affected tbe digestive structure of the predator, desorganizing the matrix perimicrovillai-midgut, indicating that it had acquired the CrylAC toxin from the prey (Cunha et al 2012).…”

The association of insect-resistant plants with biological control is important in integrated management to reduce the density of pests below the economic injury level. The behavior, development, and prédation of Podisus nigrispinus (Dallas, 1851) (Heteroptera: Pentatomidae) were studied with the prey Spodoptera frugiperda (J, E. Smith, 1797) fed on the leaves of the cotton cultivars 'NuOpal' (transgenic), 'DeltaOpal,' 'EMX 910,' 'EMX 993,' or 'FMX 996' (conventional). The attraction of P. nigrispinus to S. frugiperda larvae fed on different cotton cultivars was similar. The prédation of nymphs and adults, and the life cycle of the P. nigrispinus predator were higher for S. frugiperda larvae fed on the NuOpal; however, the total viability of P, nigrispinus was lower when predating on S. frugiperda fed the NuOpal. S, frugiperda acquires toxins from transgenic cotton, which can affect its natural predator P. nigrispinus.

“…More detailed studies carried out by da Cunha et al [47], with the same insect, showed that the Cry1Ac toxin expressed in this plant generated humoral and cellular changes as a sign of response to a xenobiotic. The toxin ingested by a lepidopteran (third trophic level) induced changes in the distribution of glycogen, lipids, and calcium due to the disorganization of the perimicrovilllar matrix of the gut.…”

Mode of Action and Specificity of Bacillus thuringiensis Toxins in the Control of Caterpillars and Stink Bugs in Soybean Culture

The bacterium Bacillus thuringiensis (Bt) produces delta-endotoxins that possess toxic properties and can be used as biopesticides, as well as a source of genes for the construction of transgenic plants resistant to insects. In Brazil, the introduction of Bt soybean with insecticidal properties to the velvetbean caterpillar, the main insect pest of soybean, has been seen a promising tool in the management of these agroecosystems. However, the increase in stink bug populations in this culture, in various regions of the country, which are not susceptible to the existing genetically modified plants, requires application of chemicals that damage the environment. Little is known about the actual toxicity of Bt to Hemiptera, since these insects present sucking mouthparts, which hamper toxicity assays with artificial diets containing toxins of this bacterium. In recent studies of cytotoxicity with the gut of different hemipterans, susceptibility in the mechanism of action of delta-endotoxins has been demonstrated, which can generate promising subsidies for the control of these insect pests in soybean. This paper aims to review the studies related to the selection, application and mode of action of Bt in the biological control of the major pest of soybean, Anticarsia gemmatalis, and an analysis of advances in research on the use of Bt for control hemipterans.

“…In Troglophilus neglectus (Orthoptera, Rhaphidophoridae) and Sarcophaga ruficornis (Diptera, Sarcophagidae), a few mitochondria extend into the microvilli (Delakorda et al, 2009;Pal and Kumar, 2013). In contrast, there is a lack of mitochondria in the microvilli in Podisus nigrispinus (Hemiptera, Pentatomidae), Graphosoma lineatum (Heteroptera, Pentatomidae), Locusta migratoria (Orthoptera, Acrididae), and Schistocerca gregaria (Orthoptera, Acrididae) (Prado et al, 1992;da Cunha et al, 2012;Amutkan et al, 2015). When compared with the Malpighian tubules of other species, those of G. campestris, which have long microvilli (about 2-5 µm) on the apical surface, do not have mitochondria in the microvilli.…”
