Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen

Mahurin Honors College Capstone Experience/Thesis Projects

The Nimba Mountain Range in Guinea, Ivory Coast, and Liberia is within the Upper Guinean Forests, a critical biodiversity hotspot highly threatened by various human activities. The region is home to many endemic species including the viviparous Nimba toad, Nimba otter-shrew, and the discrete Bossou chimpanzee population. Dung beetles can act as a focal taxon from which extrapolation to the diversity of other taxa and ecosystem health can be made. Elevational trends in dung beetle diversity were investigated on the Nimba Mountain Range and in the nearby Bossou Chimpanzee reserve in Guinea. Dung beetle species diversity surveys aimed to document …

A Comparison Of Bee Abundance And Species Richness In Three Managed Grassland Types, Emily Russ

Mahurin Honors College Capstone Experience/Thesis Projects

Bees are threatened by environmental changes, pathogens, and pesticides (Pettis, 2012, Meeus et al., 2018). The goal of the study is to compare and evaluate the bee abundance and species richness in three different field types. My hypothesis is that bees would favor the fields planted for their benefit, and that the tall grass dominated plantings would be preferred over mowed fescue. My findings have low power considering few replicates and the use of relative abundance and relative species richness for statistical analyses. Bee abundance and species richness had an overall positive relationship of varying degrees across habitat types. Relative …

A Review And Comparison Of U.S. State Wildlife Action Plans For Stonefly (Insecta, Plecoptera) Species Of Greatest Conservation Need, Kathryn Greene

Mahurin Honors College Capstone Experience/Thesis Projects

State Wildlife Action Plans (SWAPs) were created in order to identify Species of Greatest Conservation Need (SGCN) and develop plans to prevent their populations from further decline and the possibility of being listed as threatened or endangered. Which SGCNs are included are decided based on characteristics that determine their vulnerability. As of early 2021, approximately 720stoneflies (Insecta, Plecoptera) species are found in the U.S., but only 143 are listed as SGCN. Only 29 states have stoneflies included on their SGCN lists, but 37 states use EPT (Ephemeroptera + Plecoptera + Trichoptera) metrics when assessing water quality issues in running water …

Visual Control Of Refuge Recognition In The Whip Spider Phrynus Marginemaculatus, Kaylyn A.S. Flanigan, Daniel D. Wiegmann, Patrick Casto, Vincent J. Coppola, Natasha R. Flesher, Eileen Hebets, Verner Peter Bingman

Eileen Hebets Publications

Amblypygids, or whip spiders, are nocturnally active arachnids which live in structurally complex environments. Whip spiders are excellent navigators that can re-locate a home refuge without relying on visual input. Therefore, an open question is whether visual input can control any aspect of whip spider spatial behavior. In the current study, Phrynus marginemaculatus were trained to locate an escape refuge by discriminating between differently oriented black and white stripes placed either on the walls of a testing arena (frontal discrimination) or on the ceiling of the same testing arena (overhead discrimination). Regardless of the placement of the visual stimuli, the …

Identification And Quantification Of 11 Airborne Biochemicals Emitted By The Brown Recluse And Another Primitive Hunting Spider Using Headspace Solid-Phase Microextraction-Gc/Ms, Zachary Foulks, Jennifer Parks, William Stoecker, Charles Kristensen, Eileen A. Hebets, Honglan Shi

Eileen Hebets Publications

Loxosceles reclusa, or brown recluse spider, is a harmful household spider whose habitat extends throughout the Midwest in the USA and other regions in the world. The pheromones and other biomolecules that facilitate signaling for brown recluses and other spider species are poorly understood. A rapid and sensitive method is needed to analyze airborne spider signaling biomolecules to better understand the structure and function of these biochemicals in order to control the population of the spiders. In this study, we developed a novel headspace solid-phase microextraction (HS-SPME)-GC/MS method to analyze potential pheromones and biomolecules emitted by the brown recluse …

Multisensory Integration Supports Configural Learning Of A Home Refuge In The Whip Spider Phrynus Marginemaculatus, Kaylyn A.S. Flanigan, Daniel D. Wiegmann, Eileen Hebets, Verner Peter Bingman

Eileen Hebets Publications

Predator diets represent a potential interaction between local prey availability, prey antipredator defenses, and predator foraging behavior. Female spider-specialist muddauber wasps (Hymenoptera: Sphecidae) collect spiders and provision them intact, but paralyzed, to their developing larvae, providing a unique means of quantifying the diversity and abundance of prey that they capture. Mud-dauber wasps are hypothesized to be a major source of selection on antipredator defenses in web-building spiders, and the spiny and thickened abdomens of female spiny orb-weaving spiders (Araneae: Araneidae) are hypothesized to function as antiwasp defenses. We inventoried spider prey from nests of the mud-dauber wasps Sceliphron caementarium (Drury) …

Evaluation Of Biotype 4 Aphis Glycines (Hemiptera: Aphididae) Induced Susceptibility On Soybean And Soja, Jakob David Hicks

Electronic Theses and Dissertations

Soybean aphids have been a significant pest of soybeans in North America since 2000. Before 2000, soybeans did not face significant insect pest pressure from any arthropods with piercing-sucking mouthparts. It is estimated that economic damage from soybean aphids range from $1billion to $4.7 billion annually. Research efforts focused on the identification of host plant resistance genes in soybean and discovered many resistant to Aphis glycines genes (i.e., Rag genes) in soybean. However, the adoption of commercially released Rag soybean cultivars has been limited. The prospect of management with Rag genes was further complicated by the identification of three virulent …

Use Of Lymesim 2.0 To Assess The Potential For Single And Integrated Management Methods To Control Blacklegged Ticks (Ixodes Scapularis; Acari: Ixodidae) And Transmission Of Lyme Disease Spirochetes, Shravani Chitineni, Elizabeth R. Gleim, Holly D. Gaff

Undergraduate Honors Theses

Annual Lyme disease cases continue to rise in the U.S. making it the most reported vector-borne illness in the country. The pathogen (Borrelia burgdorferi) and primary vector (Ixodes scapularis; blacklegged tick) dynamics of Lyme disease are complicated by the multitude of vertebrate hosts and varying environmental factors, making models an ideal tool for exploring disease dynamics in a time- and cost-effective way. In the current study, LYMESIM 2.0, a mechanistic model, was used to explore the effectiveness of three commonly used tick control methods: habitat-targeted acaricide (spraying), rodent-targeted acaricide (bait boxes), and white-tailed deer targeted acaricide (4-poster …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein

Department of Entomology: Faculty Publications

Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

Landscape Characterization Of Floral Resources For Pollinators In The Prairie Pothole Region Of The United States, Autumn H. Smart, Clint R.V. Otto, Alisa L. Gallant, Michael P. Simanonok

Department of Entomology: Faculty Publications

Across agricultural areas of the Prairie Pothole Region (PPR), floral resources are primarily found on public grasslands, roadsides, and private grasslands used as pasture or enrolled in federal conservation programs. Little research has characterized the availability of flowers across the region or identified the primary stakeholders managing lands supporting pollinators. We explored spatial and temporal variability in flower abundance and richness across multiple grassland categories (i.e. general grassland, conservation grassland, and engineered pollinator habitat) in the PPR from 2015 to 2018 and used these data to estimate the number of flowering stems present across the region on private and public …

Characterizing The Relationship Between Western Corn Rootworm (Coleoptera: Chrysomelidae) Larval Survival On Cry3bb1-Expressing Corn And Larval Development Metrics, Jordan D. Reinders, David S. Wangila, Emily Robinson, B. Wade French, Lance Meinke

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a significant pest of field corn, Zea mays L. (Poales: Poaceae), across the United States Corn Belt. Widespread adoption and continuous use of corn hybrids expressing the Cry3Bb1 protein to manage the western corn rootworm has resulted in greater than expected injury to Cry3Bb1-expressing hybrids in multiple areas of Nebraska. Single-plant bioassays were conducted on larval western corn rootworm populations to determine the level of resistance present in various Nebraska counties. The results confirmed a mosaic of susceptibility to Cry3Bb1 across Nebraska. Larval development metrics, including head capsule width …

Overview Of The Insect Food And Feed Industry, Daniel J. Seckman

Department of Entomology: Distance Master of Science Projects

The entomophagy field is one that when you immerse yourself in it, you will feel like the entire world is talking about insects as food and feed. Yet, from the outside, the industry is virtually nonexistent. In the United States, the North American Coalition for Insect Agriculture (NACIA) is the leading organization dedicated to growing the insect food and feed sector. While the organization has grown extensively in recent years, most individuals in the food, feed, and entomological industry have never heard of the organization. The Wall Street Journal presents the annual Food Forum, which aims to “tackle the critical …

Mosquitoes Of Wisconsin: The Biology, Life History, Identification And Control, Timothy Wucherer

Department of Entomology: Distance Master of Science Projects

In the past 60 years, weather in Wisconsin has generally been getting warmer, and in many areas of the state, wetter (Moran et al., 2015). Long-term analysis of Wisconsin’s climate has indicated an increase in average annual precipitation, longer growing seasons, and an increase in average temperatures (Moran et al., 2015). Increases in temperatures and rain have been directly correlated with increases in vector-borne diseases such as pathogens carried by mosquitoes (Moran et al., 2015). With this, Wisconsin communities should prepare for possible increases in mosquito activity and the health and veterinary concerns that come with direct exposure to certain …
