Resumo: | (Effects of ester fractions from leaf epicuticular waxes of Bauhinia rufa (Steud.) Bong. and Stryphnodendron adstringens (Mart.) Coville from the cerrado on the aphid Rhopalosiphum maidis (Fitch.)). Ester fractions were isolated from the leaf epicuticular waxes of Bauhinia rufa (Steud.) Bong. and Stryphnodendron adstringens (Mart.) Coville collected in the Cerrado de Emas (Pirassununga, SP, Brazil). The bioassays of toxicity and reproductive index were carried out with esters from these species and the aphid Rhopalosiphum maidis (Fitch.). It was observed that the ester fractions from Bauhinia rufa and Stryphnodendron adstringens had a negative effect on the survival of Rhopalosiphum maidis. The ester fraction from Stryphnodendron adstringens also had a negative effect on the reproductive index of the aphid. These parameters decreased with the increase of ester concentration of artificial diets.
