1. Performance of tomato cultivars (Lycopersicon esculentum Mill.) organically-grown under greenhouse conditions. / Desempenho de cultivares de tomate (Lycopersicon esculentum Mill.) sob sistemas orgânicos em cultivo protegido.
Organic agriculture in Brazil has increased about 30% over the last few years since consumers are seeking for healthier foods, i.e. nutritious and free of pesticide residues. Among vegetable crops organically-grown, tomato constitutes an attractive economic opportunity for growers. However, the lack of information about management practices and cultivars ada

2. Interação de inseticidas e controle biológico natural na redução dos danos de Spodoptera frugiperda (J.E. SMITH, 1797) (Lepidoptera: Noctuidae) na cultura do milho (Zea mays).
All the experiments were conducted inside of the experimental area of Embrapa Milho e Sorgo (Embrapa National Maize and Sorghum Research Center) in Sete Lagoas, MG, Brazil with the objective of evaluating the role of natural enemies and insecticides on the damages of Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) in maize crop. In the first experimen

3. Modelagem da evolução da resistência de pragas a toxinas Bt expressas em culturas transgênicas: quantificação de risco utilizando análise de incertezas. / Modeling pest resistance evolution to bt toxins expressed by transgenic crops: risk assessment using uncertainty analisys.
One of the main risks associated to transgenic crops expressing Bacillus thuringiensis (Bt) toxins is the pest resistance evolution, process driven by genetic and ecological inter related factors. A key parameter that influences the rate of resistance evolution is the initial frequency of the resistance allele in the pest population (FreqInicial). Due to com
