Chrysodeixis includens (Lepidoptera: Noctuidae) on soybean treated with resistance inducers
Abstract
Plant resistance levels can be boosted to enable better pest management. The objective of this study was to evaluate resistance interaction between four soybean genotypes and three inducers resistant to integrated management of Chrysodeixis includens. The assays were performed in the entomology laboratory. The soybean genotypes were seeded and plants were treated with calcium and magnesium silicate on soil and sodium silicate and Acibenzolar-S-methyl (ASM) spray on leaves. The weight, longevity and viability of the larvae, the duration and viability of the pre-pupal stage; the weight, longevity and viability of the pupae and the duration and viability of the egg to adult stage of C. includens were observed using plants leaves. The resistant cultivars IAC 100 and IAC 17 associated with the calcium and magnesium silicate inducers and sodium silicate lengthened larval stage and induced high mortality in the C. includens adults.
