Resumo: This study was developed to determine the effect of phosphate-potassic fertilization on the occurrence of soybean insect pests. Plots were arranged in a randomized complete block design in a 4 by 4 factorial experiment (four phosphate levels and four potassic levels) with three replications. The levels of phosphorus and potassic tested were, respectively: 0, 80, 120 and 160 kg/ ha of P2O5 and 0, 40, 60 and 80 kg/ha of K2O. The insect population survey was carried out on a weekly-basis starting from the V2 stage, using ground-cloth. The results showed a tendency of population growth of Piezodorus guildinii (Westwood) for the highest levels of nutrients. Some leaf nutrients were correlated with Diabrotica speciosa (Germar).
