This work evaluates the Arctiinae fauna in Altamira, Pará, in an area with strong human pressure, using light-traps during two nights at each stage of the new moon each month, from December 2007 to November 2008. The evaluation parameters were: richness, abundance, constancy, diversity index and evenness (Shannon H ‘and E’) and Brillouin (H and E), dominance of Berger-Parker (BP). The richness estimatives were made by means of non-parametric procedures, Bootstrap, Chao 1, Chao 2, Jackknife 1, Jackknife 2 and Michaelis-Mentem. We captured 420 specimens belonging to 64 species of Arctiinae, and 19 species recorded for the first time in the state of Pará. The values of the parameters analyzed for the total period were: H ‘= 4.69; E’ = 0.781; H = 4.37; E = 0.732 and BP = 0.183. During the less rainy season (June-November) we found the most significant values for all parameters. In the rain season (December to May) we found the most significant percentage of similarity. Richness estimators predicted the gathering of more than 18.7% to 60.9% of species. |
