Spatial distribution of nymphs and adults of Euschistus heros (Fabricius, 1794) (Heteroptera: Pentatomidae) in transgenic soybean cultivars of different maturing cycles

Semina: Ciências Agrárias, 2018
The neotropical stink bug Euschistus heros is the predominant and most important insect pest affecting soybean cultivation. Knowledge of the spatial pattern of the pest in an area is critical to understanding its behavior.

Variable Levels of Resistance of Soybean Genotypes on the Performance of Euschistus heros (Hemiptera: Pentatomidae) [PDF]

Journal of Economic Entomology, 2017
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.

Soybean induced resistance to Spodoptera eridania herbivory

Pest Management Science, EarlyView.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Valorization of Ficus carica Pruning Residues as Selective Botanical Insecticides: Optimized Furanocoumarin Extraction, Efficacy Against Neotropical Stink Bugs, and Mechanistic Insights via Molecular Docking

Archives of Insect Biochemistry and Physiology, Volume 122, Issue 4, August 2026.
Optimized extracts from Ficus carica pruning waste exhibit strong biological activity against major stink bug pests. Complementary in silico analyses suggest this efficacy relies on pest‐specific acetylcholinesterase inhibition, predicting a promising, pollinator‐safe alternative for sustainable agriculture.

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

Journal of Applied Entomology, Volume 150, Issue 7, Page 914-922, August 2026.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Mode of Action and Specificity of Bacillus thuringiensis Toxins in the Control of Caterpillars and Stink Bugs in Soybean Culture

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
The bacterium Bacillus thuringiensis (Bt) produces delta‐endotoxins that possess toxic properties and can be used as biopesticides, as well as a source of genes for the construction of transgenic plants resistant to insects. In Brazil, the introduction of Bt soybean with insecticidal properties to the velvetbean caterpillar, the main insect pest of ...
