“…In studies with species of Hemiptera, such as aphids and planthoppers, no Cry protein or only a small amount of Cry protein was detected after they were fed Bt plants (Burgio et al., ; Romeis & Meissle, ; Yu et al., ; Chen et al., ; Zhao et al., ). The use of transgenic plants has become a tactic widely used in the world specifically for the management of lepidopteran soybean pests (Schünemann et al., ).…”

Euschistus heros (Hemiptera: Pentatomidae) is considered a major insect pest in soybean production in Brazil. The indiscriminate application of pesticides to fields leads to reduction in biodiversity, selection of resistant populations, emergence of new pest outbreaks, and damage to non‐target organisms. The objective of this research was to evaluate the effects of exposure to Cry proteins present in new isolates of Bacillus thuringiensis Berliner, commercial formulations, and Bt soybean on E. heros development. The feeding preference of E. heros for Bt‐ vs. non‐Bt soybean was also evaluated. All treatments caused significant mortality to E. heros except the Bt soybean. Tests with combinations of isolated Bt‐toxins indicated that combinations had greater efficacy than other treatments (>98% mortality). The results demonstrate that E. heros is susceptible to B. thuringiensis toxins, which may contribute to the management of this insect in soybean agro‐ecosystems.
