Economic thresholds were already developed for this pest. The model includes biotic (predator) and abiotic (temperature) factors, which affect the soybean aphid population dynamics.engFuzzy systemsInput variablesMathematical modelPredator prey systemsSociologyStatisticsTrabalho apresentado em evento10.1109/NAFIPS-WConSC.2015.7284183Acesso aberto2-s2.0-84961879725
