Interpretive Summary: The brown marmorated stink bug (BMSB) is an invasive species native to Asia that has been found in North America and Europe. Researchers in the United States have recently identified the pheromone of the species and have found that when combined with the pheromone from another stink bug species native to Asia, there is increased attraction. The current study evaluated whether BMSB is attracted to the same stimuli in its native range in South Korea by using pyramid traps baited with the above odors. We found that both nymphal and adult BMSB are most attracted to the combination of the two odors in traps, similar to the results found reported in the United States. This work has global implications, as it suggests that these stimuli can be used in worldwide surveillance programs and as effective components of management programs.

Technical Abstract: The brown marmorated stink bug or Halyomorpha halys is a globally invasive species that causes agricultural and nuisance problems. Researchers in the United States recently identified the H. halys aggregation pheromone from populations in the introduced range and found that when it is combined with the pheromone synergist methyl decatrienoate (MDT), it results in reliable, season-long captures of H. halys throughout the United States. However, no one has assessed whether populations in its native range in South Korea can also reliably be captured by the combination of these stimuli. In this study, our goal was to evaluate the response of H. halys adults, nymphs, and nontarget organisms to traps baited with MDT and the aggregation pheromone alone or in combination at three locations in South Korea. We found that traps with combined stimuli reliably captured the greatest abundance of H. halys adults and nymphs, and that each lure caught a unique community of nontarget organisms. Finally, we found that Plautia stali was cross-attracted to the H. halys aggregation pheromone. Overall, we demonstrate that the pheromone-based tools developed in the United States may be used for worldwide detection and surveillance programs for H. halys.
