The objective of this research was to study the effect of previous herbivory in the chemical composition of soybean leaves, and its influence on Anticarsia gemmatalis (Hüeb.) and Piezodorus guildinii (West.) development. Two soybean genotypes, 'Embrapa 4' and 'BR 37', were chemically analyzed. The caterpillars were fed on these genotypes leaves and the bugs on string beans, both injured and non- injured (control), totalizing 4 treatments with 50 replications for each treatment. Herbivory was performed by releasing 3rd instar velvetbean caterpillar. The caterpillars were taken out when 30%-40% of foliar area were consumed. After that, leaves and string beans were used in the experiment. The results obtained during this research indicate that leaves chemical composition was altered and that, in general, A. gemmatalis larvae and P. guildinii nymph have presented better development when fed on non-injured soybean plants, being 'Embrapa 4' genotype the most efficient one concerning insects development.
