A New Genus And Species Of Tiger Beetle, Pseudocollyris Shooki (Coleoptera: Cicindelidae), From Yunnan, China, Wen-Xuan Bi, Jürgen Wiesner

Insecta Mundi

A new genus, Pseudocollyris Bi and Wiesner, is established for the new species Pseudocollyris shooki Bi and Wiesner (Coleoptera: Cicindelidae), from Western Yunnan, China. A description, diagnostic features and illustrations of habitus are provided.

In 2017, the first author collected one remarkable tiger beetle during a survey in Western Yunnan, China. The beetle shows an elongated body, a metallic purple elytral surface with a pair of bright median spots and coarse punctation. Such appearance superficially resembles species of the tribe Collyridini (e.g. Collyris Fabricius, 1801 or Neocollyris Horn, 1901). However, detailed investigations of the beetle indicate it belongs to …

Occurrence Status Of The Fall Armyworm (Lepidoptera: Noctuidae) In South Korea, Soo-Jung Suh, Deuk-Soo Choi, Sol-Moon Na

Insecta Mundi

To respond to the growing risk from Spodoptera frugiperda (J.E. Smith), the migratory fall ar­myworm (Lepidoptera: Noctuidae), the National Fall Armyworm Surveillance Program (NFASP) for early detection for this pest ran from April to November during 2019 and 2020. The fall armyworm surveillance program involved seasonal monitoring of the pest with pheromone traps placed in fields of cereal crops at high-risk locations. The trapping season ran from early spring to late autumn, with a total deployment of 396 traps. During the survey of 2019 to 2020, a total of 120 male adults of S. frugiperda were captured in these …

Taxonomic Revision Of Eunota Togata (Laferté-Sénectère, 1841) (Coleoptera: Cicindelidae) In North America With A New Subspecies From Western Texas And New Mexico, United States, Robert E. Acciavatti

Insecta Mundi

Within Nearctic Cicindelidae, Cicindelini, Eunota togata (LaFerté-Sénectère, 1841) (Coleoptera: Cicindelidae) exists as several distinct phenotypes, some described as subspecies whose taxonomic status has been misinterpreted. Eunota togata togata applies to adults marked with broadly sinuate inner margins on shiny brown elytra common across northern coastal Gulf of Mexico. Eunota togata fascinans (Casey, 1914), new synonymy, incorrectly applied to populations in western Texas and New Mexico, United States, is considered a junior synonym of E. togata globicollis (Casey, 1913), the predominant subspecies with broadly sinuate inner margins on coppery elytra found from eastern New Mexico and western Texas into the …

Increased Cave Use By Butterflies And Moths: A Response To Climate Warming?, Otto Moog, Erhard Christian, Rudolf Eis

International Journal of Speleology

Between 2015 and 2019, the list of Lepidoptera from “cave” habitats (i.e., proper caves, rock shelters and artificial subterranean structures) in Austria grew from 17 to 62 species, although the effort of data collection remained nearly constant from the late 1970s onwards. The newly recorded moths and butterflies were resting in caves during daytime in the the warm season, three species were also overwintering there. We observed Catocala elocata at 28 cave inspections, followed by Mormo maura (18), Catocala nupta (7), Peribatodes rhomboidaria, and Euplagia quadripunctaria (6). More than half of the species have been repeatedly observed in caves …

Title: Soil Macroinvertebrate Responses to Wildfires in the Blue Ridge Mountains, USA Authors: 1Madeline N. Olliff, 1Bruce A. Snyder, 2Melanie K. Taylor, and 2Mac A. Callaham

1Georgia College and State University, Milledgeville, Georgia, USA; 2USDA Forest Service, Southern Research Station, Athens, Georgia, USA

Abstract: Wildfires are of increasing concern in light of climate change, more frequent late summer droughts, and increasing incidence of human ignitions. There have been few studies examining the effects of wildland fires on soil macroinvertebrates in the Blue Ridge Mountains, in spite of the importance of these animals to soil processes, and their contributions to the …

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 …

Macroinvertebrate Responses To Hydrological Variation In Experimental Wetlands., Sergio A. Sabat-Bonilla

College of Graduate Studies: Theses & Dissertations

Predicted increases in the frequency of intense storms and periods of severe drought due to climate change represent a threat to wetland macroinvertebrate communities through alterations to the hydrological regime. I used experimental ponds to assess the effects of water permanence (i.e., duration of flooding) on the communities of aquatic macroinvertebrates. I predicted that permanent ponds would harbor higher diversity of longer-lived taxa whereas temporary ones will favor colonization by quick turnover, short-lived taxa and support lower consumer diversity. Results show differences in macroinvertebrate communities between permanent and temporary ponds can be mostly explained by hydrology and the amount of …

The Reconstruction Of Hatchery Creek: Effects On Macroinvertebrate And Fish Community Dynamics, Patrick Vrablik

Murray State Theses and Dissertations

Hatchery Creek is a restored stream in Jamestown, KY that drains Wolf Creek National Fish Hatchery. The previous degraded channel of Hatchery Creek caused large sediment plumes in the Lower Cumberland River and was restored to decrease sediment loss and provide the opportunity for a self-sustaining trout population. I predicted that the increased amount of habitat would increase taxa richness, abundance and biomass of macroinvertebrates. Macroinvertebrates were monitored in three periods; the degraded period, a one-year recovery period, and a restored period using surber and kicknet samples in order to determine biomass, abundance, diversity, taxa richness, and macroinvertebrate biotic index. …

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 …

Lepidopteran Granivory Reduces Seed Counts In A Rare Species Of Riparian Scour Prairies, Cheyenne Moore, Angela J. Mcdonnell, Scott Schuette, Christopher T. Martine

Faculty Journal Articles

In Pennsylvania Baptisia australis var. australis is found along only four waterways: the Allegheny River, Youghiogheny River, Clarion River, and Red Bank Creek. Because of its limited distribution and small number of extant populations, the species is considered state-threatened in Pennsylvania. In addition, the riparian prairie habitat that Pennsylvania Baptisia australis var. australis is restricted to is also in decline and considered vulnerable. Because of these conservation concerns, insights into the natural history of the taxon in the state is valuable and will inform conservation efforts. Field surveys and fruit collections along the Allegheny River and herbarium collections were used …

Scoping Review Of Distribution Models For Selected Amblyomma Ticks And Rickettsial Group Pathogens, Catherine A. Lippi, Holly D. Gaff, Alexis L. White, Sadie J. Ryan

Biological Sciences Faculty Publications

The rising prevalence of tick-borne diseases in humans in recent decades has called attention to the need for more information on geographic risk for public health planning. Species distribution models (SDMs) are an increasingly utilized method of constructing potential geographic ranges. There are many knowledge gaps in our understanding of risk of exposure to tick-borne pathogens, particularly for those in the rickettsial group. Here, we conducted a systematic scoping review of the SDM literature for rickettsial pathogens and tick vectors in the genus Amblyomma. Of the 174 reviewed articles, only 24 studies used SDMs to estimate the potential extent …

Importance Of Instream Habitat To Recruitment And Community Structure Of Aquatic Invertebrates, Catherine R. Billé

Master’s Theses

This thesis investigates how mechanisms of colonization by aquatic insects, both by ovipositing adults and or larval drift, operate at either micro-, meso-, or macro-scales to influence larval community assemblage in streams. Our study took place in a forested floodplain stream characterized by uniform soft clay and loose detritus substrate. Within this study reach we built three sets of riffles, with each set comprised of three identical riffles built either 15, 10, or 5 m apart. We examined microscale influences on community assemblage by studying recruitment of egg masses to our constructed riffles. We found that riffle habitat additions were …

The Social Behavior Of Pine Sawflies In The Genus Neodiprion, John W. Terbot Ii

Theses and Dissertations--Biology

Group living is found across the animal kingdom ranging from temporary mating aggregations to complex, eusocial lifestyles. A particularly common form of group living found among insects are larval or nymphal herds. This lifestyle consists of immature insects living together and results in several proposed costs and benefits. Benefits of this lifestyle include improved ability to regulate a group’s microenvironment, more efficient use of their host, and the ability to engage in collective predator defenses. Offsetting these benefits are costs resulting from living in close proximity to conspecifics which include increased competition, greater visibility to predators, and heightened disease risks. …

Solifuge (Camel Spider) Reproductive Biology: An Untapped Taxon For Exploring Sexual Selection, Alfredo V. Peretti, David E. Vrech, Eileen Hebets

Eileen Hebets Publications

The exploration of new and diverse animal groups in the study of sexual selection is both necessary and important to help better understand broad patterns and test sexual selection hypotheses regarding the evolutionary origins and maintenance of reproductive tactics and associated traits. Solifuges are, in this matter, an exceptional group and very little explored from the sexual selection point of view. At first glance, mating is apparently quite simple and conserved within this arachnid order, but solifuge reproductive behavior is unique among arachnids and more diverse than previously thought. In particular, these voracious animals appear to exhibit high sexual conflict, …

Spiders (Araneae) Collected As Prey By The Mud-Dauber Wasps Sceliphron Caementarium And Chalybion Californicum (Hymenoptera: Sphecidae) In Southeastern Nebraska1, Tyler B. Corey, Earl Agpawa, Eileen Hebets

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) …

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 …

Weak Olfactory Preferences Of The Gall Midge Asphondylia Borrichiae, Associated Fungal Endophytes And Implications On Gene Flow And Host Range Expansion, Frances S. Nagle

UNF Graduate Theses and Dissertations

Asphondylia borrichaie is a small fly (Diptera: Cecidomyiidae) that is currently undergoing host-associated sympatric divergence. Asphondylia borrichaie is an ambrosia galler, these insects utilize a host plant for oviposition, but its offspring also rely on a symbiotic fungus (or fungal community) to promote the formation of the gall as well as serve as a food source for the developing larvae. Previous studies indicate that A. borrichaie consists of two host- associated populations based on its original host plant Borrichia frutescens (Asterales: Asteraceae), and another one from the two Iva species (I. frutescens (Asterales: Asteraceae) and I. imbricata …

Response Of Forest Birds To Spotted Wing Drosophila (Drosophila Suzukii Matsumura), A Novel Invasive Fruit Pest, At Allegheny National Forest, Daniel P. Roche

Graduate Theses, Dissertations, and Problem Reports (ETD)

Non-native invasive insect pests can have dramatic impacts on native ecosystems, feeding on plant foliage, wood, or sap. Little is known, however, about how fruit-targeting NNIIPs may affect native ecosystems. Spotted wing Drosophila (Drosophila suzukii Matsumura, SWD) is a recently introduced invasive vinegar fly that parasitizes the fruits of many plant species in the United States. While its activity in agricultural systems is well-documented, little is known about its activity in forest ecosystems, despite growing evidence of its presence and parasitism of fruits there. Parasitism could reduce fruit attractiveness for vertebrate fruit consumers, including migratory birds. As such, this …
