Transgenic plants expressing Bacillus thuringiensis proteins can indirectly affect natural enemies of target insects, and the assessment of these effects is essential in risk analysis of genetically modified plants. The biology of Podisus nigrispinus (Dallas) (Hemiptera Pentatomidae) and changes in the predation behaviour of this insect when fed with Bt (Cry1Ab) maize-fed Spodoptera frugiperda (J. E. Smith) larvae (Lepidoptera Noctuidae) was evaluated. The predator showed 43.7% delay in the nymphal development time and 15% biomass reduction in the fifth instar, probably due to low nutritional quality of prey exposed to Bt maize. Survival curves were similar in predators fed with S. frugiperda larvae exposed and not exposed to Bt maize. The predator search time was slightly influenced by the developmental delay of S. frugiperda fed with Bt maize. In a greenhouse assay P. nigrispinus was important in controlling S. frugiperda density in Bt maize expressing the Cry1Ab protein. Our laboratory results indicate that Bt maize may cause indirect effects on P. nigrispinus, and suggest that nutritional prey-quality factors other than the Bt protein determine the observed negative effects. However, the semi-field greenhouse assays demonstrate that indirect negative effects of Bt maize on the predator?s performance and search behaviour is not substantiated, and that plant damage is lowest if Bt maize is used concurrently with biological control by P. nigrispinus for managing S. frugiperda.

The organomineral fertilizers can release organic compounds during their solubilization, and those compounds can affect the plant growth. The aim of this study was to evaluate the initial development of wheat, nutrient accumulation in the plant and soil chemical changes, with the use of organic, mineral and organomineral fertilizers. The experiment was conducted in a greenhouse using an Acrisol cultivated with wheat (Triticum aestivum). Six treatments were tested: 100% of the nutrient recommendation in organomineral form (OMF 100); broiler litter in the same amount present in the OMF 100 (BL 10); mineral fertilizer in the same quantity present in the OMF 100 (MF 90); 100% of the nutrient recommendation in the form of broiler litter (BL 100); 100% of the nutrient recommendation in mineral form (MF 100); and a control without fertilization (CONT). The treatments were evaluated at six sampling times: 2, 4, 8, 15, 30 and 80 days after implantation. No significant differences were observed between fertilizers in dry matter yield. In the soil, there was a decrease in availability of N, P and K over time. By equivalence, all the sources tested can be used in the supply of nutrients to the wheat crop.Key words:biofertilizer; broiler litter; fertilization; Triticum aestivu |
