Resumo: | The objectives of the studies was to collect, to identify and to compare the main species of Lepidoptera found in native and planted forests, by the use of light traps and also to study the populacional fluctuation of the main species, to apply and analyse faunal indices (dominance, abundance, frequency, diversity and constancy) and Cluster. The experiment was conducted at farm São Nicolau, municipality of Cotriguaçu, Sate of Mato Grosso, Brazil, propryet of the Organizacion Nationale du Fôret/Peugeot - ONF Brazil. The survey was done from July 2007 to June 2008, which included the installation of 15 light traps model "Luiz de Queiroz" adapted, distributed in three traps for each environment: plantation of Tectona grandis, intercropped planting composed of species of Ficus spp., Astronium sp., Jacaranda copaia, Syzygium jambolanum and Aspidosperma sp., native forest, secondary forest and riparian forest. The data were submitted to wildlife program ANAFAU determining indices of dominance, abundance, frequency, diversity and consistency. The fluctuation was done taking into account the most frequent species classified as dominant, very abundant, very frequent and constant. In the study of similarities of the areas was used cluster analysis by the software Statistic. Were collected in five environments a total of 4,160 individuals, 34 species common to the sampled environments, and the families Crambidae, Noctuidae, and Arctiidae quantitatively the most significant with 44.60%, 20.62% and 18.67% respectively. The native forest (H ': 4,08) and secondary forest (H': 3,76) were the most diverse environments in species, while the environments Tectona grandis and intercropped planting were the most representative number of individuals collected. In the classification of communities there was similarity in secondary forest environments and riparian forest. In a general context, the specie Maruca vitrata was quantitatively the most representative. The population peak of most species occurred at the beginning of the rainy season in the region. |
