“…In northeastern North America S. noctilio is now the most abundant woodwasp attacking pines (Long et al 2009;Ryan et al 2012a;Foelker et al 2016). Unfortunately, there are no records of the population densities or tree use by S. nigricornis before S. noctilio arrived but now, use of suppressed pines by S. nigricornis is much less than use of this resource by S. noctilio (e.g., Table 2).…”

“…Sirex noctilio has a temporal advantage over S. nigricornis as many emerge 1-2 months before S. nigricornis, although there is overlap in emergence between these species in northeastern North America (Ryan et al 2012a;Haavik et al 2013;Hartshorn et al 2016;Suppl. material 1: B).…”

“…Sirex nigricornis is associated with one of two fungal symbionts: either the same fungal symbiont as S. noctilio (A. areolatum) or Amylostereum chailletii Olatinwo et al 2013). Sirex nigricornis can co-occur in pines with S. noctilio (Ryan et al 2012a;Hajek et al 2013). Most adults of S. nigricornis emerge to mate and oviposit approximately 1-2 months after S. noctilio (Ryan et al 2012a;Foelker et al 2016;Suppl.…”

Functional traits are useful for comparing the resource use of invasive and native species, with goals of identifying resource overlap to predict competitive interactions. The invasion of northeastern North America by the woodwasp Sirex noctilio has resulted in competition with the native congeneric Sirex nigricornis for suppressed and weakened pines. We compared sizes of adults, venom glands, fecundity, tree species use, voltinism and abundance of the invasive woodwasp S. noctilio with the native S. nigricornis in northeastern North American pines. Rearing adults from attacked pines showed that these species used the same tree species but S. noctilio were far more abundant, especially with increasing time since establishment. Adults of the invasive S. noctilio were larger than S. nigricornis, female S. noctilio had larger glands carrying phytotoxic venom in relation to body size, average-sized S. noctilio females carried more eggs, and S. noctilio developed faster than S. nigricornis. Sirex noctilio was the dominant woodwasp infesting suppressed pines in our study areas. We hypothesize that the future abundance of S. nigricornis could depend in part on the availability of wood for oviposition by this native that is not available or acceptable to the earlier-emerging S. noctilio.

The Sirex woodwasp, Sirex noctilio, and its fungal mutualist, Amylostereum areolatum, together constitute one of the most damaging invasive pests of pine. Despite a century of research and well-established management programs, control remains unpredictable and spread continues to new areas. Variable success in managing this pest has been influenced by complex invasion patterns, the multilayered nature of biological interactions, the varying local ecologies, and microevolutionary population processes in both the biocontrol organisms and in the wasps. Recent research findings are challenging the historical perspectives on methods to manage the Sirex woodwasp, calling for management programs to incorporate the variable local dynamics affecting this pest complex. In this regard, the Sirex woodwasp provides a superb model to illustrate the need for a different approach to develop efficient and sustainable management tools to deal with the growing and global nature of pest invasions in forests and plantations.

Community resistance to an invasive forest insect–fungus mutualism

Antagonistic species interactions may prevent introduced species from becoming invasive in novel geographic ranges. Within mutualisms, resistance to any partner can impact the mutualism as a whole. Larvae of the globally invasive Sirex woodwasp Sirex noctilio (Hymenoptera: Siricidae) complete their development in the sapwood of Pinus spp. (Pinaceae) only in the presence of the fungus, Amylostereum areolatum (Basidiomycota). In the Southern Hemisphere where Pinus are introduced, Sirex noctilio is an outbreak invasive pest, but in North America where Pinus is indigenous it has not irrupted to economic levels 15+ yr since introduction. To test the biotic resistance hypothesis, we characterized the arthropod community attracted to and co‐infesting Pinus resinosa trees at the geographic frontier of its introduced North American range, quantified antagonistic interactions observed within trees, and assayed competition of fungal species under laboratory conditions. A suite of potential natural enemies and competitors inhabited Sirex‐infested P. resinosa trees. Trees experimentally exposed to ovipositing Sirex noctilio females and to physical wounding attracted greater numbers of saprophagous beetles (Cerambycidae: Xylotrechus sagittatus and Curculionidae: Ips pini) and parasitoid wasps (Ichneumonidae: Ibalia leucospoides) compared to undamaged controls. Recruitment of Xylotrechus and Ibalia was positively related to numbers of oviposition scars left by Sirex females. Within xylem tissue, abundant Xylotrechus larvae killed and consumed more than 10% of Sirex larvae. This facultative intraguild predation was positively density‐dependent but nonlinear, with a unimodal peak at intermediate Sirex density. Sirex density in xylem was weakly, negatively related to Ips bark beetle density, suggesting potential competition between fungal associates (Ascomycota: Ophiostoma ips) for sapwood resources. Benchtop experiments in natural and artificial media supported the hypothesis of competition between Ips and Sirex fungal associates, with faster growth and competitive dominance of the bluestain fungus under most scenarios tested. Altogether, this study provides evidence for multiple mechanisms of biotic resistance, whereby a resident community reduces survival or performance of both an invasive insect and its fungal mutualist.
