Composição de Carabidae (Coleoptera) em sistema produtivo de soja/milho

Abstract

The Ground beetles occurrence in agricultural areas can contribute to pest control as well as indicate environmental quality. This study aimed to evaluate the composition of the Carabidae community in an agricultural area of annual crops. Ninety-six pitfall traps were installed in a grid 10 meters apart. The experimental area had one hectare in a double-cropping system of soybean (summer) and corn (autumn-winter) followed by a fallow period. Ground beetle composition analysis was performed using ANAFAU software. We collected 42 species and 1537 specimens of Carabidae distributed in 14 tribes. Harpalini tribe was the most common compared to the others. Were considered predominant, in the fauna analysis, the species Calosoma alternans granulatum Perty, 1830, Selenophorus discopunctatus Dejean, 1829, Selenophorus alternans Dejean, 1829, Selenophorus sp.1, Tetracha brasiliensis (Kirby, 1819), Abaris basistriata Chaudoir, 1873 and Galerita collaris Dejean, 1826. Thus, a diverse and abundant Carabidae community was identified in that cropping system.
