Halyomorpha halys (Stål), the brown marmorated stink bug, is an invasive, polyphagous insect that causes serious economic injury in particular to specialty crops in the United States. Growers have been forced to respond by increasing the frequency of broad-spectrum insecticide (e.g., neonicotinoid, pyrethroid, and carbamate) applications. One strategy to(More)
The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a highly polyphagous and mobile pest causing crop damage aggregated at the perimeters of crop fields. Understanding the dispersal biology of H. halys is critical for the development of reliable monitoring and management strategies. In this study, dispersal(More)
The brown marmorated stink bug, Halyomorpha halys, is an invasive insect in the United States that is capable of inflicting significant yield losses for fruit, vegetable, and soybean growers. Recently, a male-produced aggregation pheromone of H. halys was identified as a 3.5:1 mixture of (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and(More)
Halyomorpha halys is an invasive species from Asia causing major economic losses in agricultural production in the mid-Atlantic region of the United States. Unlike other crop pests, H. halys is also well-known for nuisance problems in urban, suburban, and rural areas, as massive numbers of adults often invade human-made structures to overwinter inside(More)
Halyomorpha halys (Stål), brown marmorated stink bug, is an invasive insect native to Asia that was accidently introduced into the United States. The species is a polyphagous pest that has caused serious economic injury to specialty and row crops in the mid-Atlantic region. Growers have targeted H. halys with broad-spectrum materials by increasing the(More)
Tumor necrosis factor-α (TNF-α) plays an important role in inflammatory responses. Deregulated activation of TNF-α signaling is associated with various inflammatory diseases. In view of the finding that the seventy percent ethanol extract of Litsea japonica (LJE) interferes with TNF-α-induced NF-κB activation, activity- guided fractionation was performed to(More)
The brown marmorated stink bug, Halyomorpha halys, is considered a serious invasive species capable of causing significant agricultural and nuisance problems. Researchers in the USA recently identified the two-component H. halys aggregation pheromone from populations in North America and found that when it is combined with the pheromone synergist methyl(More)
The brown marmorated stink bug, Halyomorpha halys (Stål) is a recent example of a serious biological invasive species, especially in the United States. It has also emerged as a global invasive pest, being detected in Canada, Switzerland, Liechtenstein, Germany, France, Greece, Hungary, and Italy. Halyomorpha halys is native to Asia and described as an(More)
Tagged Colorado potato beetles (CPB), Leptinotarsa decemlineata (Say), were released on potato plants, Solanum tuberosum L., and tracked using a portable harmonic radar system to determine the impact of host plant spatial distribution on the tendency of the pest to remain on the colonized host plant or patch. Results confirmed the long residency time on the(More)
This study examined habitat use patterns by adult whiteflies, Bemisia argentifolii Bellows and Perring, in response to predators, Delphastus catalinae (Horn), at different spatial scales. When female whiteflies were confined to small arenas with leaf discs from which they could not escape, whiteflies significantly delayed settling on leaf discs when(More)
