To study prevalence of brown marmorated stink bug (Halyomorpha halys) in host trees, researchers led by Nicole Quinn at Virginia Tech used an eye bolt and pulley system so that the pheromone-baited traps could be raised or lowered along the height of the tree. Their findings suggest that monitoring efforts for the stink bug and its egg parasitoid wasp Trissolcus japonicus should seek higher placement in tree canopies and that ground-based traps may miss or underestimate presence of both the pest and its parasitoid.
