Population Fluctuation of Pseudalus limona (Lepidoptera, Erebidae, Arctiinae) in an Amazonian Savannah of the alter do chão environmental protection area, Santarém, Pará, Brazil

The tiger moth (Lepidoptera: Erebidae: Arctiinae) Pseudalus limona Schaus, 1896 occurs almost exclusively in Brazil. The caterpillar of this polyphagous species primarily feeds on plants from the families Anacardiaceae, Connaraceae, Proteaceae, and Vochysiaceae. In this study, the population dynamic...

Sumario:The tiger moth (Lepidoptera: Erebidae: Arctiinae) Pseudalus limona Schaus, 1896 occurs almost exclusively in Brazil. The caterpillar of this polyphagous species primarily feeds on plants from the families Anacardiaceae, Connaraceae, Proteaceae, and Vochysiaceae. In this study, the population dynamics of P. limona were monitored monthly using light traps in an Amazonian savannah over a one-year period (June 2014 – May 2015). Population data were analyzed and correlated with meteorological variables—mean temperature, relative humidity, and rainfall—using multiple regression analyses. Analysis of variance (ANOVA) was applied to assess population fluctuations across months. A total of 175 individuals were collected, with abundance decreasing significantly from the wet season (135 individuals) to the dry season (40 individuals). Significant correlations of varying degrees were found between meteorological factors and monthly abundance fluctuations. The highest monthly abundances were recorded during periods of lower mean temperatures and higher relative humidity and precipitation.
