- 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.
- 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.
- Refining Pheromone Lures for the Invasive Halyomorpha halys (Hemiptera: Pentatomidae) Through Collaborative Trials in the United States and EuropeLeskey, Tracy C.; Andrews, Heather; Bady, Angelika; Benvenuto, Luca; Bernardinelli, Iris; Blaauw, Brett R.; Bortolotti, Pier Paolo; Bosco, Lara; Di Bella, Emanuele; Hamilton, George; Kuhar, Thomas P.; Ludwick, Dalton; Maistrello, Lara; Malossini, Giorgio; Nannini, Roberta; Nixon, Laura J.; Pasqualini, Edison; Preti, Michele; Short, Brent D.; Spears, Lori; Tavella, Luciana; Vetek, Gabor; Wiman, Nik (2021-08)Brown marmorated stink bug, Halyomorpha halys, is native to Asia and has invaded North America and Europe inflicting serious agricultural damage to specialty and row crops. Tools to monitor the spread of H. halys include traps baited with the two-component aggregation pheromone (PHER), (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and (3R,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol, and pheromone synergist, methyl (2E,4E,6Z)-decatrienoate (MDT). Here, an international team of researchers conducted trials aimed at evaluating prototype commercial lures for H. halys to establish relative attractiveness of: 1) low and high loading rates of PHER and MDT for monitoring tools and attract and kill tactics; 2) polyethylene lure delivery substrates; and 3) the inclusion of ethyl (2E,4E,6Z)-decatrieonate (EDT), a compound that enhances captures when combined with PHER in lures. In general, PHER loading rate had a greater impact on overall trap captures compared with loading of MDT, but reductions in PHER loading and accompanying lower trap captures could be offset by increasing loading of MDT. As MDT is less expensive to produce, these findings enable reduced production costs. Traps baited with lures containing PHER and EDT resulted in numerically increased captures when EDT was loaded at a high rate, but captures were not significantly greater than those traps baited with lures containing standard PHER and MDT. Experimental polyethylene vial dispensers did not outperform standard lure dispensers; trap captures were significantly lower in most cases. Ultimately, these results will enable refinement of commercially available lures for H. halys to balance attraction and sensitivity with production cost.
