Dissertação (Mestrado em Agronomia) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/9908The soybean is one of the main commodities traded in international markets. Among countries, Brazil is the second largest producer of soybean, beating production records each season. However, despite the increasing soybean production in Brazil, some factors may hinder the development of culture, including the action of insect pests. So the kind of importance quarantine Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), registered in the country in 2013, is a major concern in soybean crops, as both attacks a vegetative and reproductive parts, causing economic damage to the crop. Thus, the objective of this study was to evaluate biological parameters of this pest in vegetative and reproductive stages of soybean, seeking the applicability of this knowledge in the Integrated Pest Management (IPM). For the realization of the experiments, soybean plants were grown in the field in staggered plantings, and the insects were created and maintained in the laboratory with controlled temperature and humidity.Three treatments were used: such as leaves (vegetative stage), leaves with flower (reproductive stage) and pods (reproductive stage). For each treatment were individualized 150 caterpillars in plastic pots, where they remained until they become pupae. After the emergence same age adult couples were individualized in PVC cages, fed with a 10% honey solution. We evaluated the periods of development of the larval stage, pre-pupal and pupa stages, adult longevity, and the feasibility of each of these phases. In addition, we also evaluated pupal weight, sexual ratio, pupa strain percentage and adults, daily and total fertility. It was also built the fertility life table. The leaves in the vegetative phase of soybeans were the most suitable for the development of H. armigera, with higher total viability, completing the cycle (egg to adult) with 33.20 days, while leaves with flower cycle was 35.50 days .The treatment with only Pod had no larval development, dying after exposure to treatment. Fertility was also higher in the treatment with leaves, with 1613 eggs per female, while in the treatment leaves with flower was 520.28 eggs per female. It was no possible construct fertility life table of the flower and leaf treatment, due to high mortality and therefore, obtaining only a few adults. The fertility life table values of the treatment with leaves obtained were: mean generation time (T): 48.30; net reproductive rate (R0): 52.57; intrinsic growth rate (rm): 0.036; and finite rate of increase (λ): 1.04. Soybean leaf in the vegetative stage is more suitable to the development and reproduction of H. armigera. The results serve to support the Integrated Management of H. armigera in soybean.application/pdfAcesso AbertoBiologiaTabela de vidaManejo integrado de pragasBiologyLife tableIntegrated pest managementAGRONOMIA::FITOSSANIDADEDissertação
