Abstract: The brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) has a very broad host range and is a key pest in vegetable and fruit production. Native to China, Republic of Korea, DPR Korea and Japan, it has been accidentally introduced into the United States, Canada, Switzerland, Liechtenstein, Germany, France, Italy, Hungary and Greece since the mid-1990s. With its rapid expansion, this insect is possibly becoming a serious agricultural pest worldwide. In the newly invaded areas, little nature enemy is found to control this pest efficiently. For example, indigenous parasites Telenomus podisi and Trissolcus flavipes in Canada and Switzerland respectively can attack H. halys eggs, but neither wasp can complete development successfully. As chemical pesticides would cause social and ecological side effects, classical biological control is consider a promising management approach, which leading to permanent establishment and long-term control H. halys in invaded areas by introducing a co-evolved host specific biological control agent. In this paper, we reviewed taxonomy, distribution, damage, biology, ecology and biological control of H. halys, with particular focus on nature enemies in the area of origin.
