The Neotropical brown stink bug Euschistus heros (Fabr.) (Hemiptera: Pentatomidae) is one of the major soybean pests in South America. This species is responsible for high levels of infestation, causes critical damage to seeds, it is associated with leaf retention on plants, and it is extremely difficult to manage. Host plant resistance is a notable technique to assist in reducing the stink bug population in soybean crops. The antibiosis resistance of soybean genotypes to E. heros was evaluated in laboratory. Genotypes L1-1-01, 'IAC 100', 'IAC 23', and 'Coodetec 208' increased the length of nymphal developmental time. PI 274453 and PI 227687 reduced egg viability and also adult body weight. PI 274454, 'IAC 19', PI 227687, and PI 229358 led to low nymphal viability. These results suggest that these genotypes may be useful in soybean breeding programs that focus on the development of genotypes resistant to E. heros.
新热带褐蝽Euschistus heros（法布尔）（半翅目：蝽科）是南美洲大豆的主要害虫之一。该物种造成大量虫害，对种子造成严重损害，与植株叶片滞留有关，且极难防治。寄主植物抗性是协助减少大豆作物中蝽虫数量的一项重要技术。在实验室中评估了大豆基因型对E. heros的抗生性。基因型L1-1-01、“IAC 100”、“IAC 23”和“Coodetec 208”延长了若虫发育时间。PI 274453和PI 227687降低了卵的活力以及成虫体重。PI 274454、“IAC 19”、PI 227687和PI 229358导致若虫活力低下。这些结果表明，这些基因型可能对专注于培育抗E. heros基因型的大豆育种计划有用。
