(2020-04-08) Hallinen, Marie J; Wittman, Jacob T; Steffens, Wayne P; Schultz, Jennifer L; Aukema, Brian H; MarieHallinen@gmail.com; Hallinen, Marie J; University of Minnesota Forest Entomology Lab
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 and code for "Optimizing early detection strategies: defining the effective attraction radius of attractants for emerald ash borer"
(2021-04-30) Wittman, Jacob T; Silk, Peter; Parker, Katie; Aukema, Brian H; wittm094@umn.edu; Wittman, Jacob T
From the publication: 1. Adult emerald ash borers are attracted to green prism traps baited with the ash host volatile (3Z)-hexenol and the sex pheromone of emerald ash borer (3Z)-dodecen-12-olide [(3Z)-lactone]. Quantifying the heretofore unknown range of attraction of such traps would help optimize deployment strategies for early detection. 2. Examining trap captures of traps deployed in pairs at variable distances offers insight into the range of attraction. Recent work has shown the range of attraction can be estimated as half the intertrap distance at which trap catch begins to decrease, which should occur when proximate traps overlap their respective attractive ranges. 3. We illustrate estimation of the traps' attractive range for emerald ash borer using ninety-eight baited green prism traps deployed in pairs, one trap per tree, in an urban park in Saint Paul, Minnesota, USA in summer 2020. 4. We estimate attractive range by fitting a logistic model to trap catch data using Bayesian inferential methods and describe advantages thereof. 5. The attractive range of these baited traps was estimated to be between 16 -- 73m, with a median of 28m. We recommend that green prism traps baited with these semiochemicals be placed 25 - 35m apart near high-risk entry points.
Data and code for forecasting overwintering mortality of Spathius galinae in North America
(2021-04-26) Wittman, Jacob T; Aukema, Brian H; Duan, Jian J; Venette, Robert C; wittm094@@umn.edu; Wittman, Jacob T
From publication: Evaluating the cold tolerance of biological control agents is often necessary to optimize their release and performance. We used field and laboratory assays to determine the cold hardiness of the parasitoid Spathius galinae Belokobylskij & Strazanac, an approved classical biological control agent of emerald ash borer (Agrilus planipennis Fairmaire) in North America. Supercooling points and lower lethal temperature of mature (cocooned) S. galinae larvae were measured in controlled cooling assays in the laboratory. Most S. galinae larvae died after reaching their supercooling point, which occurred at -25.0°C on average. Several larvae, however, initiated freezing but later eclosed, suggesting S. galinae may be partially freeze tolerant. Supercooling points were not affected by chilling rate. In the winter of 2019 – 2020, we monitored development of mature S. galinae larvae in ash segments above and beneath the snow in three locations in Minnesota, USA. Nearly 100% of S. galinae larvae died after air temperatures reached -29°C in Minnesota. Using models developed from our data, we forecast eclosion rates of S. galinae based on minimum winter temperatures across the range of ash (Fraxinus spp.) in North America. Our results indicate that S. galinae populations may suffer high overwintering mortality in areas where winter temperatures regularly decrease below -28°C, but a small portion of the population may be able to survive lower temperatures.

Data from: Development of an aggressive bark beetle on novel hosts: Implications for outbreaks in an invaded range
(2017-11-11) Rosenberger, Derek W; Venette, Robert C; Aukema, Brian H; dwrosenberger@olivet.edu; Rosenberger, Derek W
Mountain pine beetle (Dendroctonus ponderosae Hopkins) is an aggressive bark beetle native to western North America currently expanding its range east. Should it reach northeastern North American pine forests, it is unclear how novel pine hosts might affect traits related to reproduction and development. These data are the result of studies meant to determine how four novel pine hosts might impact mountain pine beetle reproduction and development, relative to two historical hosts.

European fruit lecanium (Parthenolecanium corni) occurrence in hybrid hazelnut plantings in Minnesota and associated parasitoid fauna from 2022
(2023-07-27) Traband, Simone G; Aukema, Brian H; Luhman, John C; Shanovich, Hailey N; hnshanovich@gmail.com; Shanovich, Hailey N
These data were collected in the summer of 2022 as an independent undergraduate research project at the University of Minnesota by Simone Traband (undergraduate student, class of '24) under the mentorship of Hailey Shanovich (graduate student, class of '23). The goals of the project were to collect preliminary data on 1) the abundance of a soft scale insect pest, European fruit lecanium (Parthenolecanium corni), on hybrid hazelnut plants (Corylus americana x Corylus avellana) in experimental plantings at the University of Minnesota research stations, and 2) the prevalence of biological control by Hymenopteran parasitoid wasps and an endoparasitic fungi (Ophiocordyceps clavulata). These data accompany the paper "Synopsis of biological control for European fruit lecanium (Parthenolecanium corni) by parasitoids in North America and preliminary findings in hybrid hazelnut orchards" by Traband et al. 2023 in the Great Lakes Entomologist. The preliminary field experiment was conducted at two experimental hybrid hazel plantings in Rosemount, Minnesota. Full details of study sites and other methodology can be found in the paper by Traband et al. 2023. On 11 July 2022 seven infested hazel plants were chosen to sample for scale insects from one hybrid hazelnut planting (n=7), and then on 22 July 2022 from two hybrid hazelnuts plantings (n = 4, n = 3) for a total of 14 plants. On each date, sampling of each plant was done for 15 person-minutes (i.e., three observers searching each plant for scales for five minutes), during which branches observed to contain one or more scale insects, no matter the status (i.e., showed signs of parasitism or not), were collected via hand pruners. Collected branches were immediately brought back to the lab and thoroughly examined to determine the number and status of every scale insect broken into three categories: showing signs of parasitism by fungus (i.e., fungal stromata protruding from scale insect), showing signs of parasitism by Hymenopteran parasitoids (i.e., containing a parasitoid exit hole in shell), or showing no signs of parasitism (i.e., showing no signs of parasitism). Branches containing scales showing no signs of parasitism were preserved for a duration of three weeks for purposes of parasitoid rearing and inspected every other day and any emerged parasitoids were collected and frozen until they could be identified. On 8 August 2022, all scale insects contained in jars were inspected for parasitoid exit holes, dissected to check for parasitoid larvae, pupae, or adults, and then discarded. All collected Hymenopteran parasitoid wasps were identified to the lowest taxonomic level possible.
Hazelnut and adult hazelnut weevil monitoring at Minnesota sites from 2020-2022
(2023-07-14) Shanovich, Hailey N; Anderson, Pheylan A; Aukema, Brian H; hnshanovich@gmail.com; Shanovich, Hailey N
This data was collected in order to determine the phenology of adult hazelnut weevils (Curculio obtusus) within interspecific hybrid hazelnut (Corylus americana x Corylus avellana) plantings in Minnesota and identify hazelnut factors that might be driving the weevils within-field abundance and infestation/damage in the crop between different hazelnut genotypes. Adult hazelnut weevil lay eggs into developing hazelnuts and their larvae then develop inside hazelnuts, devouring the edible kernel, directly impacting crop yield. Therefore, the objective was to determine when this behavior occurs in the Minnesota crop and to identify any plant-level or nut-level factors driving spatial trends in their abundance and nut infestation within the hazelnut plantings.
