Interpretive Summary: Brown marmorated stink bug (BMSB) is an invasive species native to Asia that is now present in many states throughout the USA. While pyramid traps baited with the BMSB aggregation pheromone and pheromone synergist are good tools for monitoring their presence, abundance and seasonal activity, other trap designs such as clear sticky traps deployed on wooden posts offer additional flexibility as they are easier to deploy. Here, we evaluated captures on baited pyramid and sticky traps in 18 states across the Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest and Western regions of the USA. We found that while pyramid traps typically capture greater numbers of adults and nymphs than clear sticky traps, their captures are strongly correlated at low, moderate and high population densities and at early-, mid- and late-season time frames. Among regions, greatest captures were in the Southeast and Mid-Atlantic, and lowest in the West. Results show that either trap type when baited with pheromonal stimuli offers reliable, season-long monitoring for BMSB activity.

Technical Abstract: Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. Halyomorpha halys adult and nymphal captures on clear sticky traps were compared with captures in black pyramid traps in 18 states across the Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest and Western regions of the USA. Traps were baited with commercial lures containing the H. halys pheromone and synergist, and deployed at field sites bordering agriculture or urban locations with H. halys host plants. Nymphal and adult captures in pyramid traps were greater than those on sticky traps, but captures were positively correlated between the two trap types within each region and during the early-, mid- and late-season across all sites. Sites were further classified as having a low, moderate or high relative H. halys density and again showed positive correlations between captures for the two trap types for both nymphs and adults. Among regions, the greatest adult captures were recorded in the Southeast and Mid-Atlantic on pyramid and sticky traps, respectively, with lowest captures recorded in the West. Nymphal captures, while lower than adult captures, were greatest in the Southeast and lowest in the West. Nymphal and adult captures were, generally, greatest during July-August and September-October, respectively. Trapping data were compared with available phenological models. Results demonstrated that sticky traps offer a simpler, less expensive alternative to pyramid traps, but both can be reliable tools to monitor H. halys populations in different geographical locations with varying population densities throughout the season.
