Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Distribution data of Polydrusus spp. north of Mexico and seasonal phenology of two nonindigenous Polydrusus species in Minnesota hybrid hazelnut orchards
    (2023-02-01) Shanovich, Hailey N; Lisak, Sarah C; Lindsey, Amelia R I; Aukema, Brian H; hnshanovich@gmail.com; Shanovich, Hailey N
    1. Polydrusus_sampling_data.csv: This data was compiled to examine the seasonal phenology of adult Polydrusus weevils in hybrid hazelnut orchards and examine the relative phenologies and sex-ratios between the nonindigenous species found. 2. Daily_temperatures_and_GDD.csv: This data was compiled in order to calculated accumulated growing degree days for the collected Polydrusus weevils each year. Data was collected via a datalogger at the field sites.

    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.
