ABSTRACT
Halyomorpha halys, the brown marmorated stink bug, is a pentatomid species native to Asia, specifically China, Japan, Korea, Myanmar, Taiwan, and Vietnam. Outside North America, it has been found in shipments from the United States and Asia to New Zealand and Australia, has been detected or become established in several European countries and in Santiago, Chile, and has become an agricultural pest in northern Italy. Biological invasion represents a major threat to biodiversity and ecosystem functioning, resulting in great economic losses. Spatial attributes affecting the large-scale movement, distribution, and potential range of Halyomorpha halys include annual mean temperature, maximum temperature of warmest month, minimum temperature of the coldest month, annual precipitation, annual mean radiation, wetland rights-of-way, urban developments, railroads, and elevation. Halyomorpha halys is well-known for causing nuisance problems, as large numbers of adults often invade human-made structures to overwinter inside protected environments. Adults of Halyomorpha halys move into orchards or other crops when the sugar content of fruit increases.
