“…Predicting future potential ranges of pests is essential for pest control because such information can aid the identification of priority regions for pest control. Studies of the potential ranges of pests have thus received much attention in previous decades [1][2][3][4][5]. For example, Hof and Svahlin (2016) detected the range expansions of pests under future change scenarios in the Swedish boreal forest and identified priority regions for pest control in the peripheral regions of Norrland [6].…”

Future Range Shifts Suggest That the Six-Spined Spruce Bark Beetle Might Pose a Greater Threat to Norway Spruce in Europe than the Eight-Spined Spruce Bark Beetle

Both the eight-spined spruce bark beetle (eight-spined beetle, Ips typographus) and the six-spined spruce bark beetle (six-spined beetle, Pityogenes chalcographus) have major deleterious effects on Norway spruce (i.e., Picea abies, the host tree) in Europe. However, future potential range shifts of the two pests and their range overlap with Norway spruce have not yet been characterized. Through range dynamic models, we characterized their future range expansions, as well as their range overlap with their host tree under current–future change scenarios in 2100. Host availability was the greatest contributor to the range shifts of the two pests, and climatic changes were the main drivers of the range expansion of the host. The potential range, expanded range, and overlapped range were larger for the six-spined beetle than for the eight-spined beetle. The host tree, i.e., Norway spruce, might face increasing threats from the two pests in the future. Future climate change will likely indirectly facilitate range shifts of pests by promoting increases in the area capable of sustaining the host tree. The six-spined beetle might pose a greater threat to Norway spruce than the eight-spined beetle, albeit the latter has previously been considered to have more deleterious effects on Norway spruce.

“…Eleven families and approximately 180 named species are currently recorded from Washington State (Smith 1979a, Gibson 1980, Goulet 1986, Smith 1989, Goulet 1996, Looney et al 2012, Schiff et al 2012. Most sawfly species are herbivores, including leaf-and stem-mining species, chewing defoliators, wood-borers, and leaf-tying defoliators.…”

“…The 2009 discovery of the introduced alder-feeding sawfly Monsoma pulveratum (Retzius, 1783) in the Pacific Northwest (Looney et al 2012) provided impetus to conduct a broad sawfly survey in Washington State from 2010 through 2012. Specimens collected during that survey revealed that the Pacific Northwest range of many sawfly species is incompletely delineated, and that relatively few contributions have been made towards understanding Pacific Northwest Symphyta during recent decades.…”

Examination of museum specimens, unpublished collection data, and field surveys conducted between 2010 and 2014 resulted in records for 22 species of sawflies new to Washington State, seven of which are likely to be pest problems in ornamental landscapes. These data highlight the continued range expansion of exotic species across North America. These new records also indicate that our collective knowledge of Pacific Northwest arthropod biodiversity and biogeography is underdeveloped, even for a relatively well known and species-poor group of insects. Notable gaps in the knowledge of Washington State's Symphyta remain for the Olympic Peninsula, the Cascade Mountain Range, and the arid interior of the state. Washin gton's shrub-steppe appears to be particularly poorly surveyed for sawflies.

“…Sawfly larvae are voracious herbivores, defoliating riparian alder stands where present. First records of invasive sawflies are from Newfoundland in the 1990s (Smith & Goulet, 2000), and are currently distributed across southcentral Alaska and the Pacific Northwest (Kruse et al, 2010;Looney et al, 2012). Although the full distribution is currently unknown, invasive sawflies may present a threat in a wide range of habitats.…”

Riparian defoliation by the invasive green alder sawfly influences terrestrial prey subsidies to salmon streams

Invasive species in riparian forests are unique as their effects can transcend ecosystem boundaries via stream‐riparian linkages. The green alder sawfly (Monsoma pulveratum) is an invasive wasp whose larvae are defoliating riparian thin‐leaf alder (Alnus tenuifolia) stands across southcentral Alaska. To test the hypothesis that riparian defoliation by this invasive sawfly negatively affects the flow of terrestrial prey resources to stream fishes, we sampled terrestrial invertebrates on riparian alder foliage, their subsidies to streams and their consumption by juvenile coho salmon (Oncorhynchus kisutch). Invasive sawflies altered the composition of terrestrial invertebrates on riparian alder foliage and as terrestrial prey subsidies to streams. Community analyses supported these findings revealing that invasive sawflies shifted the community structure of terrestrial invertebrates between seasons and levels of energy flow (riparian foliage, streams and fish). Invasive sawfly biomass peaked mid‐summer, altering the timing and magnitude of terrestrial prey subsidies to streams. Contrary to our hypothesis, invasive sawflies had no effect on the biomass of native taxa on riparian alder foliage, as terrestrial prey subsidies, or in juvenile coho salmon diets. Juvenile coho salmon consumed invasive sawflies when most abundant, but relied more on other prey types selecting against sawflies relative to their availability. Although we did not find effects of invasive sawflies extending to juvenile coho salmon in this study, these results could change as the distribution of invasive sawflies expands or as defoliation intensifies. Nevertheless, riparian defoliation by these invasive sawflies is likely having other ecological effects that merits further investigation.
