Abstract:	Considering the importance of noctuids-pests (Lepidoptera: Noctuidae) for agricultural production, this thesis aimed to provide information for the understanding of the space-time relationships between the population variations of these insects with climatic factors and ecoclimatic classifications (vegetation, climate, life zones and biomes). Widespread species were studied in the American continent [Anicla infecta (Ochsenheimer), Elaphria agrotina (Guenée) and Spodoptera frugiperda (J.E. Smith)] whose caterpillars are polyphagous, but with different habits. Those of A. infecta preferentially feed on the leaf blade, those of E. agrotina, of dry plant tissues and those of S. frugiperda, of developing or reproductive plant tissues. The first study was carried out in an agricultural area in the Federal District during four crops (from July 2013 to June 2017) analyzing the population variations of the three species and the effect of climatic factors and El Niño. The second study evaluated the population variations of A. infecta in 12 locations in Brazil (Mojuí dos Campos, PA; Petrolina, PE; Rio Branco, AC; Porto Nacional, TO; Sinop, MT; Planaltina, DF; Uberaba, MG; Domingos Martins and Alegre, ES; Londrina, PR; Passo Fundo and Bagé, RS), during the 2015-2016 and 2016-2017 seasons. Variations were evaluated using Generalized Linear Models (GLM) such as Poisson Regression; Non-Parametric Tests such as Kruskal-Wallis and Cluster Analysis. The results of the first study showed that the three species showed similar annual (but not monthly) population declines at least in the first three crops. These population variations were significantly influenced by climatic factors and the Oceanic Niño Index (ONI). In the second study, it was found that A. infecta moths were constant (collected in more than 50% of the sampled months) in practically all places and their populations varied significantly depending on the months, places, vegetation, climate, life zones and biomes. The results indicated a greater association between the monthly number of moths captured with the type of vegetation and life zones (Cophenetic Correlation Coefficient greater than 0.9), showing the need to consider parameters of these classifications in monitoring studies of this specie.
