- Biology, ecology, and management of brown marmorated stink bug (Hemiptera: Pentatomidae)Rice, Kevin B.; Bergh, J. Christopher; Bergmann, Eric J.; Biddinger, David J.; Dieckhoff, Christine; Dively, Gale; Fraser, Hannah; Gariepy, Tara; Hamilton, George; Haye, Tim; Herbert, D. Ames Jr.; Hoelmer, Kim A.; Hooks, Cerruti R. R.; Jones, Ashley; Krawczyk, Greg; Kuhar, Thomas P.; Martinson, Holly; Mitchell, William; Nielsen, Anne L.; Pfeiffer, Douglas G.; Raupp, Michael J.; Rodriguez-Saona, Cesar; Shearer, Peter W.; Shrewsbury, Paula M.; Venugopal, P. Dilip; Whalen, Joanne; Wiman, Nik G.; Leskey, Tracy C.; Tooker, John F. (2014)Brown marmorated stink bug, Halyomorpha halys Stål, is an invasive, herbivorous insect species that was accidentally introduced to the United States from Asia. First discovered in Allentown, PA, in 1996, H. halys has now been reported from at least 40 states in the United States. Additional invasions have been detected in Canada, Switzerland, France, Germany, Italy, and Lichtenstein, suggesting this invasive species could emerge as a cosmopolitan pest species. In its native range, H. halys is classified as an outbreak pest; however, in North America, H. halys has become a major agricultural pest across a wide range of commodities. H. halys is a generalist herbivore, capable of consuming >100 different species of host plants, often resulting in substantial economic damage; its feeding damage resulted in US$37 million of losses in apple in 2010, but this stink bug species also attacks other fruit, vegetable, field crop, and ornamental plant species. H. halys has disrupted integrated pest management programs for multiple cropping systems. Pesticide applications, including broad-spectrum insecticides, have increased in response to H. halys infestations, potentially negatively influencing populations of beneficial arthropods and increasing secondary pest outbreaks. H. halys is also challenging because it affects homeowners as a nuisance pest; the bug tends to overwinter in homes and outbuildings. Although more research is required to better understand the ecology and biology of H. halys,we present its life history, host plant damage, and the management options available for this invasive pest species.
- Evaluating invasion risk and population dynamics of the brown marmorated stink bug across the contiguous United StatesIllán, Javier Gutierrez; Zhu, Gengping; Walgenbach, James F.; Acebes-Doria, Angel; Agnello, Arthur M.; Alston, Diane G.; Andrews, Heather; Beers, Elisabeth H.; Bergh, J.

(Wiley, 2022-11-01)BACKGROUND: Invasive species threaten the productivity and stability of natural and managed ecosystems. Predicting the spread of invaders, which can aid in early mitigation efforts, is a major challenge, especially in the face of climate change. While ecological niche models are effective tools to assess habitat suitability for invaders, such models have rarely been created for invasive pest species with rapidly expanding ranges. Here, we leveraged a national monitoring effort from 543 sites over 3 years to assess factors mediating the occurrence and abundance of brown marmorated stink bug (BMSB, Halyomorpha halys), an invasive insect pest that has readily established throughout much of the United States. RESULTS: We used maximum entropy models to estimate the suitable habitat of BMSB under several climate scenarios, and generalized boosted models to assess environmental factors that regulated BMSB abundance. Our models captured BMSB distribution and abundance with high accuracy, and predicted a 70% increase in suitable habitat under future climate scenarios. However, environmental factors that mediated the geographical distribution of BMSB were different from those driving abundance. While BMSB occurrence was most affected by winter precipitation and proximity to populated areas, BMSB abundance was influenced most strongly by evapotranspiration and solar photoperiod. CONCLUSION: Our results suggest that linking models of establishment (occurrence) and population dynamics (abundance) offers a more effective way to forecast the spread and impact of BMSB and other invasive species than simply occurrence-based models, allowing for targeted mitigation efforts. Implications of distribution shifts under climate change are discussed.
- Halyomorpha halys (Hemiptera: Pentatomidae) response to pyramid traps baited with attractive light and pheromonal stimuliRice, Kevin B.; Cullum, John P.; Wiman, Nik G.; Hilton, Richard; Leskey, Tracy C. (Florida Entomological Society, 2017-06)Halyomorpha halys Stal (Hemiptera: Pentatomidae) is an invasive insect that causes severe economic damage to multiple agricultural commodities. Several monitoring tools, including pheromone and light-baited black pyramid traps, have been developed to monitor H. halys. Here, we evaluated the attractiveness of these traps baited with only light, only pheromone, or the combination in comparison with unbaited traps throughout the growing season in regions with high and low H. halys population densities. In regions with high population densities in the Mid-Atlantic, all traps baited with pheromone or lights performed better than control traps. During mid-season, traps containing lights captured more H. halys adults, whereas pheromone-baited traps captured greater numbers during the late season. In low density regions in the Pacific Northwest, traps with lights or pheromone captured more H. halys adults than control traps. In addition, we evaluated the influence of competing light sources associated with anthropogenic structures. When light traps were deployed next to these additional light sources, H. halys captures in pyramid traps baited with light were not significantly reduced. Overall, our results indicate that both light and pheromone traps can be used to detect H. halys activity in low and high density populations.
- Indigenous arthropod natural enemies of the invasive brown marmorated stink bug in North America and EuropeAbram, Paul K.; Hoelmer, Kim A.; Acebes-Doria, Angelita L.; Andrews, Heather; Beers, Elizabeth H.; Bergh, J.

(2017-09)Since the establishment of the brown marmorated stink bug, Halyomorpha halys (Stal) (Hemiptera: Pentatomidae) in North America and Europe, there has been a large, multi-group effort to characterize the composition and impact of the indigenous community of arthropod natural enemies attacking this invasive pest. In this review, we combine 98 indigenous natural enemy datasets spanning a variety of sampling methods, habitats, and geographic areas. To date, the vast majority of H. halys biological control research has focused on the egg stage, using sentinel egg masses to characterize indigenous parasitoid and predator communities and their contribution to H. halys egg mortality. Although egg parasitism and predation levels by indigenous natural enemies are low (typically <10% each) in most surveys, total egg mortality attributable to natural enemies can be higher (typically between 5 and 25%; up to 83%)-even though these values were likely underestimated in most cases because some mortality due to biological control was not recognized. In North America, where the most data are available, it appears that the relative prevalence of different indigenous parasitoid species varies among habitat types, particularly between crop and non-crop habitats. Predator species responsible for egg mortality are much less commonly identified, but appear to include a wide variety of generalist chewing and sucking predators. To date, studies of natural enemies attacking H. halys nymphs and adults are relatively rare. Based on our review, we identify a number of key research gaps and suggest several directions for future research.
- Invasion of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) into the United States: Developing a National Response to an Invasive Species Crisis Through Collaborative Research and Outreach EffortsLudwick, Dalton; Morrison, William R. III; Acebes-Doria, Angelita L.; Agnello, Arthur M.; Bergh, J. Christopher; Buffington, Matthew L.; Hamilton, George C.; Harper, Jayson K.; Hoelmer, Kim A.; Krawczyk, Gregory; Kuhar, Thomas P.; Pfeiffer, Douglas G.; Nielsen, Anne L.; Rice, Kevin B.; Rodriguez-Saona, Cesar; Shearer, Peter W.; Shrewsbury, Paula M.; Talamas, Elijah J.; Walgenbach, James F.; Wiman, Nik G.; Leskey, Tracy C. (2020-03-11)Halyomorpha halys (Stal), the brown marmorated stink bug, is a globally invasive stink bug species. Its first major outbreak was in the United States, where it has caused millions of dollars in damage, threatened livelihoods of specialty crop growers and impacted row crop growers, and become an extreme nuisance pest in and around dwellings. The BMSB IPM Working Group, funded by the Northeastern IPM Center, was central to providing a mechanism to form a multidisciplinary team and develop initial and subsequent research, Extension, regulatory and consumer priorities. Ultimately, a project team consisting of over 50 scientists from 11 institutions in 10 states obtained the largest ever USDA-NIFA Specialty Crop Research Initiative CAP grant, totaling over $10.7 million, to tackle this crisis over a 5-yr period (2011-2016). Researchers and Extension educators integrated stakeholder feedback throughout the course of the project, and priorities evolved according to needs of affected growers and public stakeholders. Initially, the team focused on identification of H. halys, its damage symptoms and crop-specific risks, and short-term mitigation strategies for crop protection. Subsequently, work focused on its biology, ecology, and behavior leading to the development of potential longer-term IPM tactics and landscape level management solutions, including biological control. This work continues under a second SCRI CAP grant (2016-2021). The information from the initial team reached an estimated 22,000 specialty crop stakeholder contacts via Extension efforts, and over 600 million people via mainstream media. We highlight the main lessons learned from coordinating a national response to the threat posed by H. halys to agriculture in the United States.
- Season-Long Monitoring of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) Throughout the United States Using Commercially Available Traps and LuresAcebes-Doria, Angelita L.; Agnello, Arthur M.; Alston, Diane G.; Andrews, Heather; Beers, Elizabeth H.; Bergh, J. Christopher; Bessin, Ric; Blaauw, Brett R.; Buntin, G. David; Burkness, Eric C.; Chen, Shi; Cottrell, Ted E.; Daane, Kent M.; Fann, Lauren E.; Fleischer, Shelby J.; Guedot, Christelle; Gut, Larry J.; Hamilton, George C.; Hilton, Richard; Hoelmer, Kim A.; Hutchison, William D.; Jentsch, Peter; Krawczyk, Greg; Kuhar, Thomas P.; Lee, Jana C.; Milnes, Joshua M.; Nielsen, Anne L.; Patel, Dilani K.; Short, Brent D.; Sial, Ashfaq A.; Spears, Lori R.; Tatman, Kathy; Toews, Michael D.; Walgenbach, James D.; Welty, Celeste; Wiman, Nik G.; Van Zoeren, Janet; Leskey, Tracy C. (2020-02)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 and in black pyramid traps were compared in 18 states across the Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest and Western regions of the United States. Traps were baited with commercial lures containing the H. halys pheromone and synergist, and deployed at field sites bordering agricultural 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 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 showing comparable population peaks at most locations. Results demonstrated that sticky traps offer a simpler alternative to pyramid traps, but both can be reliable tools to monitor H. halys in different geographical locations with varying population densities throughout the season.
