Abstract The Neotropical brown stink bug, Euschistus heros (F.), and the green belly stink bug, Dichelops furcatus (F.) (Hemiptera: Pentatomidae), are the main sucking pests of soybean and maize in Brazil. Here, we characterized the susceptibility of populations of E. heros and D. furcatus to insecticides and define doses for resistance monitoring of E. heros. Stink bug populations collected in the seasons from 2018 to 2020 were exposed to technical grade insecticides in topical bioassays. Populations of E. heros presented low variation in the susceptibility to acephate (LD50 = 0.22–0.69 μg a.i./stink bug), thiamethoxam (LD50 = 0.0039–0.032 μg a.i./stink bug) and bifenthrin (LD50 = 0.021–0.10 μg a.i./stink bug), with resistance ratios

Euschistus heros 和 Dichelops furcatus (Hemiptera: Pentatomidae) 对杀虫剂的敏感性由局部生物测定和诊断剂量确定，用于监测巴西的 E. heros

摘要 新热带褐臭虫Euschistus heros (F.)和绿腹臭虫Dichelops furcatus (F.) (Hemiptera: Pentatomidae)是巴西大豆和玉米的主要吸食害虫。在这里，我们描述了 E. heros 和 D. furcatus 种群对杀虫剂的敏感性，并定义了 E. heros 耐药性监测的剂量。在 2018 年至 2020 年期间收集的臭虫种群在局部生物测定中暴露于工业级杀虫剂。E. heros 种群对乙酰甲胺磷（LD50 = 0.22–0.69 μg ai/臭虫）、噻虫嗪（LD50 = 0.0039–0.032 μg ai/臭虫）和联苯菊酯（LD50 = 0.1021–0.1021 μg ai/臭虫）的敏感性变化很小臭虫），具有电阻比
