Interpretive Summary: Parasitoid wasps are potent natural enemies of many species of pest insect. Correct identification, distribution data, and name usage in parasitoid wasp biology are key factors in the success of biological control. This paper extends the distribution of a newly established beneficial wasp into the Pacific Northwest, and discusses how the species may have gotten there. Biological control workers, extension agents, and APHIS cooperators worldwide will find this research product essential for their own work.
Technical Abstract: Biological agents to control the brown marmorated stink bug, Halyomorpha halys (Stål) (BMSB), in Western Europe, requires reliable taxonomic resources for identification of Trissolcus wasps. To aid this research endeavor, we present a species identification key to females of Palearctic Trissolcus. Morphological characters and concepts of species groups and the genus are discussed. We discovered a number of nomenclatural and identification issues that we have worked to clarify.
