Two stink bug-resistant soybean cultivars, Dowling and IAC 100, and one sucepible, Silvânia were selected to evaluate their influence on Euschistus heros development. Evaluation of the biology of E. heros was conducted on nymph development, adult longevity, female fecundity and egg fertility in seeds of each cultivar. The results showed that E. heros nymphs reared on cv Dowling did not complete their biological cycle, but it was completed on cvs Silvânia and IAC 100. The total amount of six isoflavonoids identified and one flavonol was higher in cv Silvânia compared to the levels quantified in cv Dowling. The results showed that cvs Dowling and IAC 100 have constitutive resistance affecting E. heros development and that the major falvonoids quantified in these cultivars are not involved in soybean antibiotic effect observed in this study.

选择了两个抗臭虫的大豆品种Dowling和IAC 100，以及一个可食用的Silvânia，以评估它们对Euschistus英雄发展的影响。对每个品种的种子中若虫发育，成年寿命，雌性繁殖力和卵育性进行了大肠杆菌英雄生物学评估。结果表明，在c。Dowling上饲养的E.英雄若虫并没有完成其生物学周期，但在cvsSilvânia和IAC 100上完成了该过程。与定量的水平相比，在cvSilvânia中鉴定出了6种异黄酮，其中一种黄酮含量更高。在简历道林。结果表明cvs Dowling和IAC 100具有影响E. heros的本构抗性 在这些研究中观察到的主要黄酮类化合物的发育没有涉及大豆抗生素的作用。
