Invasive stink bugs (Hemiptera: Pentatomidae) are responsible for high economic losses toagriculture on a global scale. The most important species, dating from recent to old invasions,include Bagrada hilaris (Burmeister), Halyomorpha halys (Stål), Piezodorus guildinii(Westwood), Nezara viridula (L.), and Murgantia histrionica (Hahn). Bagrada hilaris, H. halys,and N. viridula are now almost globally distributed. Biological control of these pests faces acomplex set of challenges that must be addressed to maintain pest populations below the economicinjury level. Several case studies of classical and conservation biological control of invasive stinkbugs are reported here. The most common parasitoids in their geographical area of origin are eggparasitoids (Hymenoptera: Scelionidae, Encyrtidae, and Eupelmidae). Additionally, nativeparasitoids of adult stink bugs (Diptera: Tachinidae) have in some cases adapted to the novel hostsin the invaded area and native predators are known to prey on the various instars. Improving theefficacy of biocontrol agents is possible through conservation biological control techniques andexploitation of their chemical ecology. Moreover, integration of biological control with othertechniques, such as behavioural manipulation of adult stink bugs and plant resistance, may be asustainable pest control method within organic farming and integrated pest management (IPM)programs. However, additional field studies are needed to verify the efficacy of these novelmethods and transfer them from research to application.
