Controle agroecológico de Aphis craccivora Koch (Hemiptera: Aphidedae) em Feijão-de-Praia

Abstract

Beach beans constitute, in the North and Northeast regions, one of the main socioeconomic alternatives for providing protein food and generating employment. Among the phytosanitary problems that occur in this crop is the black aphid Aphis craccivora, which attacks the most tender parts of the plant. The organosynthetic active ingredient flupyradifurone is the main authorized form of black aphid control. Thus, the objective of the study was to evaluate agroecological alternatives for controlling black aphids on beach beans. Natural products were used: extract of Selaginella amazonica, leaves and inflorescence of Piper aduncum and Piper hispidum, in addition to natural products, the insecticide flupyradifurone and water were used. It was observed that the use of extracts of P. aduncum, P. hispidum and S. amazonica, with two applications spaced 7 days apart, shows promise for controlling black bean aphid.
