| This study aimed to evaluate the development, survival and reproductive capacity of Spodoptera eridania in four soybean cultivars. The experiment was conducted in the laboratory, in a climatic chamber at 25 °C ± 1 °C, 70 ± 10% relative humidity and 12 h photophase. The cultivars used were: FMT Tabarana, BRS/MT Pintado, FMT Tucunaré and Monsoy 8757, all conventional cultivars with medium cycles. All cultivars tested allowed the development of S. eridania. However, Monsoy 8757 was the cultivar that most affected the prolonged in the duration larval, pupal and total cycle, showed lower pupal weight as well as reduction in the intrinsic rate increase. These results contribute to the management of this species in regions of outbreaks in soybean areas. |

| This research aimed to evaluate the insecticide potential of the leaves extract of Piper aduncum (L.) (Piperaceae) on development of brown stink bug, Euschistus heros (F.), major pest in soybean crop in Mato Grosso State. For this a bioassay was conducted with eggs, nymphs and adults of this stink bug, using the concentrations 0.5; 1.0; 2.0; 4.0 and 8.0%, of the extract acetonic of P. aduncum and acetone for control. It was evaluated the numbers of unviable eggs, nymphs death and longevity, fecundity and fertility of the adults. In the immersing eggs bioassay, all concentrations greater than 1% unviable more than 70% of the eggs, while in the contact bioassay only 19% of the eggs were unviable in 8% concentration, differing of control. In nymphs bioassay... |

| Algumas espécies de tesourinhas (Dermaptera: Forficulidae) são importantes predadoras da lagarta-do-cartucho do milho Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Neste trabalho, avaliou-se o efeito de temperaturas constantes no desenvolvimento de Doru luteipes (Scudder) e Doru lineare (Eschs.). D. luteipes não completou seu desenvolvimento nas temperaturas de 30 e 32°C, enquanto D. lineare não completou apenas na temperatura de 32°C. O período de incubação variou de 8,0 (25°C) a 17,2 dias (18°C) e de 4,6 (30°C) a 14,5 dias (18°C), para D. luteipes e D. lineare, respectivamente. A duração do período ninfal variou de 30,4 dias (25°C) a 63,6 dias (18°C), para D. luteipes, e de 20,4 dias (30°C) a 60,5 dias (18°C), para D. lineare. A duração do... |
