Rises in global trade and travel have increased the arrival rates of non-native wood-boring insects. Whereas the movement of wood-boring beetles has received considerable attention, the arrival of woodwasps (Hymenoptera: Siricidae), particularly in the United States, is poorly understood despite the establishment of several non-native tree-killing species (e.g., Sirex noctilio) in this taxon. The objective of this study was to characterize the relative abundance of siricid species arriving in the United States and New Zealand using port inspection records from 1914-2008. We present the types of species intercepted, the number of times each species was intercepted, and the region of origin for infested materials. The species most frequently intercepted were Sirex juvencus (206 interceptions), Urocerus gigas (124 interceptions), and Xeris spectrum (59 interceptions). Italy was the most common source for interceptions, associated with 23% of total interceptions, followed by Germany, associated with 17% of interceptions. Biosecurity threats posed by the movement of siricids in international invasion pathways will be discussed.
