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

Journal of Applied Entomology, EarlyView.
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.
