Brown Marmorated Stink Bug

The brown marmorated stink bug is an insect in the family Pentatomidae, native to China, Japan, Korea, and other Asian regions. In September 1998, it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become a season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to countries such as Georgia and Turkey and caused extensive damage to hazelnut production. It is now established in many parts of North America and has recently become established in Europe and South America. Scientific Name: Halyomorpha halys Range: Native to E. Asia; invasive in N.
