The association of resistant varieties and biological control has great interest and potential to be used for pest management. lhe aims of this work were to evaluate the effect of cultivars Silvânia (susceptible to stink bug attack), Dowling e IACI00 (resistant) on E. heras nymph development and to investigate the influence of the flavonoids on the resistance [1]. Nymphs of stink bug were placed in Petri dishes on a diet of soybean pods and observed daily. After adult emergence, they were weight and then put in pairs for mating. lhe nymph mortality, the adult longevity, fecundity and the eggs fertility were evaluated for each cultivar. To quantify the flavonoid compounds, extracts of immature seeds (cv Silvânia and Dowling) undamaged and damage by herbivory, were analysed using high performance liquid chromatography (HPLC). lhe nymphs reared on cv Dowling did not complete their biological cycle. Survivorship curves of immatures in cv. Sylvania and IAClOO, analysed by Kaplan-Meier Survival Distribution, did not show significant difference. lhe medium weight of adults on others cultivars was not different. lhe medium male longevity on cv IAClOOwas 11.0 days, while on cv Silvânia was 35.8 days; for females was 13.4 days on cv IAClOOand 40.6 days on cv Silvânia. lhe female fecundity (105.7 eggs/female) and egg fertility (66.3 nymphs) on cv Silvânia were higher than on cv IACI00 (10.2 eggs/female e 5.8 nymphs). Total amount of flavonoids compounds was higher in cv Silvânia than in cv Dowling, but did not differ when compared between herbivory damage and undamaged plants in the same cultivar. These results suggest that the cv IACI00 and Dowling present direct defense (constitutive) against E. heras, and that the herbivory damage did not induce flavonoids production.
