This study evaluated the Arctiinae fauna of a pasture area in Altamira, Pará, eastern Amazon, using light traps. The moths were captured at every new moon phase, two nights per phase, from December 2008 to November 2010. We evaluated the following parameters: richness, abundance, dominance, constancy, diversity indexes and evenness (Shannon H' and E'; Brillouin H and E), and Berger-Parker dominance (BP). Richness estimates were made by nonparametric procedures: Bootstrap, Chao1, Chao2, Jackknife1, Jackknife2 and Michaelis-Mentem. We captured a total of 910 specimens belonging to 85 species of Arctiinae. Values of parameters for the total period were: H' = 2.58, E' = 0.581, H = 2.45, E = 0.576 and BP = 0.433. Both richness and abundance were higher in 2009-2010, while diversity and Shannon and Brillouin evenness were higher for the year 2008-2009. Estimators predicted an increase between 18.8% to 85.9% in species richness. |
