Control strategies for Chrysodeixis includens and Spodoptera eridania caterpillars (Lepidoptera: Noctuidae) and selection of resistant cultivars in soybean

Abstract

Chrysodeixis includens and Spodoptera eridania caterpillars have been considered the most important pests for Glycine max in Brazil. This study evaluated different control strategies for these two important soybean caterp illars and the effects on crop productivity. The control strategies adopted were: BC, IPM, PUI and C (without pest control) and 2 cultivars (BMX Desafio -conventional and TEC Power IPRO - transgenic - Cry 1Ac). The experimental design was in randomized blocks in a factorial scheme (2 x 4) with four replications. The transgenic cultivar TEC Power IPRO presents efficiency in the control of Chrysodeixis includens and low efficiency for Spodoptera eridania. Harmonious practices such as IPM are the best alternative for soybean crops, to minimize Chrysodeixis includens and Spodoptera eridania infestations. The control strategy adopted did not influence soybean productivity.
