- 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. © 2022 The Authors. Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.
- Halyomorpha halys (brown marmorated stink bug)Leskey, Tracy C.; Hamilton, G. C.; Biddinger, D. J.; Buffington, M. L.; Dieckhoff, C.; Dively, G. P.; Fraser, H.; Gariepy. T.; Hedstrom, C.; Herbert, D. Ames Jr.; Hoelmer, K. A.; Hooks, C. R. R.; Inkley, D.; Krawczyk, G.; Kuhar, Thomas P.; Lee, D.-H.; Nielsen, Anne L.; Pfeiffer, Douglas G.; Rodriguez-Saona, C.; Shearer, Peter W.; Talamas, E.; Tomasino, E.; Tooker, J.; Venugopal, P. D.; Whalen, J.; Walton, V.; Makkouk, K.; Wiman, M. (2014-09-19)Following the accidental introduction and initial discovery of H. halys in Allentown, Pennsylvania, USA, this species has been detected in 41 states and the District of Columbia in the USA. Isolated populations also exist in Switzerland, France, Italy and Canada. Recent detections also have been reported in Germany and Liechtenstein. BMSB has become a major nuisance pest in the mid-Atlantic region and Pacific Northwest, USA, due to its overwintering behaviour of entering human-made structures in large numbers. BMSB also feeds on numerous tree fruits, vegetables, field crops, ornamental plants, and native vegetation in its native and invaded ranges. In the mid-Atlantic region, serious crop losses have been reported for apples, peaches, sweetcorn, peppers, tomatoes and row crops such as field maize and soyabeans since 2010. Crop damage has also been detected in other states recently including Oregon, Ohio, New York, North Carolina and Tennessee.
- 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.
- Pest status of the brown marmorated stink bug, Halyomorpha halys in the USALeskey, Tracy C.; Hamilton, G. C.; Nielsen, Anne L.; Polk, D. F.; Rodriguez-Saona, C.; Bergh, J. Christopher; Herbert, D. Ames Jr.; Kuhar, Thomas P.; Pfeiffer, Douglas G.; Dively, G. P.; Hooks, C. R. R.; Raupp, M. J.; Shrewsbury, Paula M.; Krawczyk, G.; Shearer, Peter W.; Whalen, J.; Koplinka-Loehr, C.; Myers, Elizabeth; Inkley, D.; Hoelmer, K. A.; Lee, D.-H.; Wright, S. E. (2012-10-01)Since its initial discovery in Allentown, PA, USA, the brown marmorated stink bug (BMSB), Halyomorpha halys (Heteroptera: Pentatomidae) has now officially has been detected in 38 states and the District of Columbia in the USA. Isolated populations also exist in Switzerland and Canada. This Asian species quickly became a major nuisance pest in the mid-Atlantic USA region due to its overwintering behavior of entering structures. BMSB has an extremely wide host range in both its native home and invaded countries where it feeds on numerous tree fruits, vegetables, field crops, ornamental plants, and native vegetation. In 2010, populations exploded causing severe crop losses to apples, peaches, sweet corn, peppers, tomatoes and row crops such as field corn and soybeans in several mid-Atlantic states. Damaging populations were detected in vineyards, small fruit and ornamentals. Researchers are collaborating to develop management solutions that will complement current integrated pest management programs. This article summarizes the current pest status and strategies being developed to manage BMSB in the USA.
- 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.
- Successful management of Halyomorpha halys (Hemiptera: Pentatomidae) in commercial apple orchards with an attract-and-kill strategyMorrison, William R.; Blaauw, Brett R.; Short, Brent D.; Nielsen, Anne L.; Bergh, J. Christopher; Krawczyk, Greg; Park, Yong-Lak; Butler, Bryan R.; Khrimian, Ashot; Leskey, Tracy C. (2018-07-30)Introduction of Halyomorpha halys (Stål) in the USA has disrupted many established integrated pest management programs for specialty crops, especially apple. While current management heavily relies on insecticides, one potential alternative tactic is attract-and-kill (AK), whereby large numbers of H. halys are attracted to and retained in a circumscribed area using attractive semiochemicals and removed from the foraging population with an insecticide. The goal of this study was to evaluate if AK implementation in commercial apple orchards can result in levels of H. halys damage that are equal to or less than those from grower standard management programs.Over 2 years at farms in five Mid-Atlantic USA states, we found that the use of AK resulted in 2-7 times less damage compared with grower standard plots, depending on year and period. At selected trees on which AK was implemented, over 10,000 H. halys individuals were killed in two growing seasons, and the use of AK reduced the crop area treated with insecticide against H. halys by 97%. Using AK had no impact on the natural enemy or secondary pest community over the same period.Overall, the use of AK was effective at managing low to moderate H. halys populations in apple orchards, but must be optimized to increase economic feasibility for grower adoption. © 2018 Society of Chemical Industry.
- Using IPM-CPR as a Management Program for Apple OrchardsAkotsen-Mensah, C.; Blaauw, Brett R.; Short, Brent D.; Leskey, Tracy C.; Bergh, J. Christopher; Polk, D.; Nielsen, Anne L. (2020-08)We have demonstrated how management of key orchard pests including the insect invasive species Halyomorpha halys (Stal) (Hemiptera: Pentatomidae) can be accomplished using a systems-level approach termed IPM-CPR (Integrated Pest Management-Crop Perimeter Restructuring) in apple. We conducted on-farm comparisons of IPM-CPR to standard management program for managing H. halys, Cydia pomonella (L.) (Lepidoptera: Tortricidae), Grapholita molesta (Busck) (Lepidoptera: Tortricidae), and Lygus lineolaris Palisot de Beauvois (Hemiptera: Miridae) in commercial apple orchards in 2014, 2016, and 2017 in New Jersey, Maryland, and Virginia. The presence and abundance of key pests and fruit injury at harvest were used as a measure of success of the program. We compared the amount of insecticide applied for each management program. In majority of instances, there were no differences in the IPM-CPR and the standard management program in terms of H. halys numbers in baited pyramid traps and stink bug injury at harvest. Damage from C. pomonella and G. molesta in the IPM-CPR treatment was significantly lower than the standard management program in 2014 and 2017. Amount of active ingredient used was on average 62.1% lower in the IPM-CPR treatment compared with standard management program. Despite a reduction in insecticide use, there were minimal impacts on beneficial insects. Overall, IPM-CPR in apples successfully managed key orchard pests, including H. halys, and used significantly less insecticide than a standard insecticide-based management program and could be adopted as a systems-level approach for pest population reduction.
