Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. adult nymphal captures on clear sticky traps in black pyramid were compared 18 states across Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest Western regions United States. Traps baited with commercial lures containing H. pheromone synergist, deployed at field sites bordering agricultural or urban locations host plants. Nymphal greater than those...
Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled annual seasonal common pest, Helicoverpa zea (Boddie), based on three suitability zones throughout North America using four decades soil temperatures: southern range (able persist through winter),...
Aerial traps, using combinations of color and attractive lures, are a critical tool for detecting managing insect pest populations. Yet, despite improvements in trap efficacy, collection nontarget species ("bycatch") plagues many surveys. Bycatch can influence survey effectiveness by reducing the available space target increasing screening time, especially areas where thousands insects captured as bycatch given season. Additionally, may negatively impact local populations, including...
Each year, federal and state agencies, including universities, conduct field surveys for invasive species in an attempt to detect new introductions early the invasion process. National insects are administered coordinated by United States Department of Agriculture's Animal Plant Health Inspection Service-Plant Protection Quarantine (USDA-APHIS-PPQ) Forest Service through Farm Bill § 10007 (www.aphis.usda.gov), Cooperative Agricultural Pest Survey (CAPS) (caps.ceris.purdue.edu), Early...
Habitat structure is of great importance for the distribution and abundance various organisms. Spiders are especially sensitive to structural features their environment. Although spiders influenced by habitat structure, it remains unclear whether respond architecture, differences in prey availability associated with different architectures, or both. Here, we investigated effects shrub architecture interactions on a spider community shrub-steppe environment northern Utah, USA. Big sagebrush...
The highly polyphagous and invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has become a significant insect pest in North America since its detection 1996. It was first documented northern Utah 2012 reports of urban nuisance problems plant damage have increased. Biological control is the preferred solution to managing H. other invaded regions due alignment with integrated management sustainable practices. Native non-native biological agents, namely...
Brown marmorated stink bug, Halyomorpha halys, is native to Asia and has invaded North America Europe inflicting serious agricultural damage specialty row crops. Tools monitor the spread of H. halys include traps baited with two-component aggregation pheromone (PHER), (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol (3R,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol, synergist, methyl (2E,4E,6Z)-decatrienoate (MDT). Here, an international team researchers conducted trials aimed at evaluating prototype...
Invasive species threaten the productivity and stability of natural managed ecosystems. Predicting spread invaders, which can aid in early mitigation efforts, is a major challenge, especially face climate change. While ecological niche models are effective tools to assess habitat suitability for such have rarely been created invasive pest with rapidly expanding ranges. Here, we leveraged national monitoring effort from 543 sites over 3 years factors mediating occurrence abundance brown...
Abstract Bumble bees are integral pollinators of native and cultivated plant communities, but species undergoing significant changes in range abundance on a global scale. Climate change land cover alteration key drivers pollinator declines; however, limited research has evaluated the cumulative effects these factors bumble bee assemblages. This study tests assemblage (calculated as richness abundance) responses to climate use by modeling species‐specific habitat requirements,...
Brown marmorated stink bug (Halyomorpha halys Stål) is an invasive and economically important agricultural ornamental insect pest now established in 46 U.S. states. It was first detected Utah 2012 began causing damage 2017. Tart cherry (Prunus cerasus Linnaeus) a major processed commodity Utah; yet, its susceptibility to brown unstudied.

Plants are exploited by a diverse community of insect herbivores and phytopathogens that interact indirectly through plant-mediated interactions. Generally, plants thought to respond insects pathogens different defensive signaling pathways. As selected for resistance one phytophagous organism type (insect vs. pathogen) in managed systems, it is not clear how this selection may affect This study examined the effect nematode-resistant varieties on aphid (Acyrthosiphon pisum) suppression, then...
Abstract The invasive Halyomorpha halys (Stål) is a significant agricultural and urban nuisance pest in many parts of the world. In North America, biological control H. by parasitoid wasps families Scelionidae Eupelmidae has shown promise. An effective technique for detection monitoring native exotic parasitoids deployment yellow sticky cards; however, cards also attract nontarget arthropods, reducing efficiency accuracy screening. This study sought to identify an alternative yet trapping...
The invasive and highly polyphagous brown marmorated stink bug, Halyomorpha halys (Stål), is a severe agricultural urban nuisance pest in North America. Since its initial invasion into Utah 2012, H. has become well established suburban locations along the western foothills of Wasatch Front northern Utah. Bordering Great Basin Desert, this area unique from other American with due to high elevation (> 1200 m), aridity (30-year mean RH = 53.1%; dew point -1.9 °C) extreme temperatures...
Abstract Commercialized bumble bees (Bombus) are primary pollinators of several crops within open field and greenhouse settings. However, the common eastern bee (Bombus impatiens Cresson, 1863) is only species widely available for purchase in North America. As an species, concerns have been expressed over their transportation outside native range. Therefore, there a need to identify regionally appropriate candidates commercial crop pollination services, especially western U.S.A. In this...
In its native range, Halyomorpha halys (Stål) is suppressed by parasitoids in the genus Trissolcus (Hymenoptera: Scelionidae). to Utah have demonstrated low parasitism of H. halys, while adventive japonicus (Ashmead) shown up 20%. Custom rubber septa lures containing stink bug kairomones, n-tridecane (attractant), and (E)-2-decenal (repellent), at 100%, 90%, 80% levels attractant (10 mg load rate), were placed adjacent sentinel egg masses northern field trials.
