Abstract

The diet of Podager n. nacunda in the Paraná (Entre Ríos) airport was analyzed, with specimens collected in summer of 1987. The diet included 19 taxa; Nezara viridula was the most common prey reaching high numbers and volume in the stomachs. This Hemiptera is the main pest in the study site, as during the last years soybean cultivation has been increased.
