Documenting Range Expansion Of Two Invasive Tick (Acari:Ixodidae) Species In Eastern South Dakota, Braden Wojahn
Documenting Range Expansion Of Two Invasive Tick (Acari:Ixodidae) Species In Eastern South Dakota, Braden Wojahn
Dissertations and Theses
This project documents the expanded zoogeographic ranges of the blacklegged tick (Ixodes scapularis) and lone star tick (Amblyomma americanum) within eastern South Dakota. Ticks are important when considering a “One Health” approach, as many species are competent vectors of zoonotic pathogens causing human diseases and conditions such as Lyme disease, tularemia, rickettsia, and alpha gal syndrome. The research involved constitutes two steps. First, tick surveillance was conducted in eastern counties of South Dakota, spanning March 2021 through August 2022. Surveillance took place along edge habitat at recreation areas, state and public parks, wildlife management areas and refuges, and other natural …

Tsetse flies are exclusively hematophagous and vectors of trypanosomes, which cause human and animal African trypanosomiasis. They are widely distributed in Africa, with 33 extant taxa and 22 species in three sub-genera. Despite a low reproductive rate, tsetse can maintain populations large enough to cause the restriction of the economic use of large areas of tropical Africa through the transmission of trypanosomiases. This success is largely due to their ability to navigate in their environments, using olfactory signals, which elicit critical behavioural phenotypes, such as attraction to hosts for blood meals, larviposition and resting sites, as well as avoidance of …

Introduction: Horticulture is an important sub-sector for many African countries. Tephritid fruit flies continue to cause serious direct and indirect damage to the sub-sector. The male annihilation technique (MAT) using methyl eugenol (ME) is among the most revered techniques in fruit fly management. However, ME-based lures are only available to some farmers in Africa. Several basils of the genus Ocimum produce ME. Methods: In laboratory experiments, we used a dual choice olfactometer to assess the attraction of adult oriental fruit fly Bactrocera dorsalis to intact plants, 100 µL commercial methyl eugenol (ME) (positive control), 10 mg/mL of O. tenuiflorum aqueous …
Laboratory Bioassays Of A Native Arkansas Isolate Of Metarhizium Robertsii (Hypocreales: Clavicipitaceae) And The Biopesticide Met52® For The Control Of Amblyomma Americanum (Anactinotrichidea [=Parasitoformes]: Ixodidae)., Allen Szalanski

The lone star tick, Amblyomma americanum, is the predominant human-biting tick in Arkansas and a vector of multiple pathogens of medical and veterinary importance. Increasing concerns over acaricide resistance and environmental contamination have prompted evaluation of alternative control strategies. We assessed the pathogenicity of a native Arkansas isolate of Metarhizium robertsii (Savoy P10N1) against laboratory-reared adult and nymphal A. americanum under controlled conditions. Ticks were immersed in a conidial suspension (1 × 10⁸ conidia/ml) and monitored for mortality and fungal sporulation for 77 days post-inoculation. Cumulative mortality followed a time-dependent logistic pattern, with significant fungal-induced mortality beginning at 14 …

Honey bees (Apis mellifera) are the most economically important agricultural pollinator in North America, as well as being the most frequently studied bee species. Many agricultural systems, such as fruit tree orchards, benefit from having a diversity of bee species present. In this article, we present information about the types of bees that can be found in orchards and explore their mating behaviors, life cycles, genetic differences, flower preferences, and foraging activities. Many orchard-pollinating bees, including bumble bees (Bombus spp.), mason bees (Osmia spp.), and mining bees (Andrena spp.), are often less studied than honey …
Investigation Of Fungal Pathogens And Woodboring Beetles Of Sugarbush Stands In The Central Appalachian Region, Molly A. Sherlock
Investigation Of Fungal Pathogens And Woodboring Beetles Of Sugarbush Stands In The Central Appalachian Region, Molly A. Sherlock
Graduate Theses, Dissertations, and Problem Reports (ETD)
The production of maple syrup is a valuable source of income and cultural identity for many rural communities throughout the central Appalachian region. Regardless, maple syrup producers face difficulties maintaining the health and productivity
of their stands due to various impacts of climate change, which have given rise to extreme weather events that exacerbate damage caused by pests and diseases. To ensure the long-term sustainability of the maple syrup industry, it is crucial to obtain a comprehensive understanding of the current biotic threats within the region, particularly woodboring insects and fungal pathogens. However, insufficient information exists regarding the community assemblages …
Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf
Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …
Hide And Seek: An Exploration Of Antipredator And Predator Avoidance Mechanisms In Orthopodomyia Signifera In Response To Predation From Toxorhynchites Rutilus, Nathaniel Dahlberg
Hide And Seek: An Exploration Of Antipredator And Predator Avoidance Mechanisms In Orthopodomyia Signifera In Response To Predation From Toxorhynchites Rutilus, Nathaniel Dahlberg
Master's Theses
There have been many observations of larval Orthopodomyia signifera coexisting with the predator Toxorhynchites rutilus. There are three hypotheses that could explain how Or. signifera resists predation from Tx. rutilus. The first hypothesis states that larvae adapt behavioral changes that limit predation. The second hypothesis states thoracic setae serve as a physical defense that prevents Tx. rutilus from grasping Or. signifera. The third hypothesis states Or. signifera possess a chemical defense indicated by aposematic coloration. To test the first hypothesis larval Or. signifera were exposed to conspecific and heterospecific predation cues and their behavior was observed. Both cues …
