In 2014, researchers discovered the male aggregation pheromone of the brown marmorated stink bug (Halyomorpha halys), and others later established its effectiveness in attracting the bugs using a black pyramid-style trap (left). That trap type, however, can be cumbersome to deploy. A clear sticky-panel trap using the same pheromone lure, however, has shown to be equally effective, and a new, large-scale study confirms the trap’s effectiveness in varying agricultural settings and environmental conditions.
