    We utilized a biosurveillance sampling method, namely the use of the native ground-nesting hunting wasp Cerceris fumipennis, along with University of Minnesota Insect Collection (UMSP) records, to create a checklist for Buprestidae in Minnesota, USA. We examined 5,127 specimens with Minnesota localities, documenting 107 species. Of these, 37 new state records are noted, including 11 collected from C. fumipennis nesting sites between 2013 and 2018. Maps displaying the number of beetles for a given species caught in each county and the time passed since last collection (within 20 years) are provided here as an appendix.

    Data for: Anomalous outbreaks of an invasive defoliator and native bark beetle facilitated by warm temperatures, changes in precipitation, and interspecific interactions

    Data were analyzed to quantify spatiotemporal patterns of two biotic disturbance agents, the invasive larch casebearer (Coleophora laricella Hübner) and native eastern larch beetle (Dendroctonus simplex LeConte), on eastern larch (Larix laricina (Du Roi) K. Koch)

    Eastern larch beetle reproductive success in western and subalpine larch
    (2024-10-31) Picklo, Rose; Eidson, Erika; Steed, Brytten; Aukema, Brian; bhaukema@umn.edu; Aukema, Brian; University of Minnesota Forest Entomology Lab
    Eastern larch beetle Dendroctonus simplex LeConte has been outbreaking for the past two decades in the Great Lakes region of North America, impacting approximately 400,000 hectares of eastern larch Larix laricina (tamarack) forest in Minnesota, United States, alone. Range expansions of some Dendroctonus species driven by climate change have occurred across North America as rising temperatures increase climatically suitable habitats across latitudes and elevations. The range of eastern larch beetle is currently sympatric to that of its host, eastern larch, but the insect could, in theory, eventually access ranges of other species of Larix native to North America. We compared host suitability of two potential novel hosts, western larch (Larix occidentalis Nutt.) and subalpine larch (Larix lyalli Parl.) against the beetle’s native host, eastern larch, using a reproductive success experiment conducted in cut bolts of all three species. We measured fertility, maternal gallery length, and offspring size and lipid content as metrics of reproductive success. We share data here upon publication of this work in the journal Frontiers in Forests and Global Change.
