Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets

Eileen Hebets Publications

Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …

Modeling The Geographic Distribution Of Ixodes Scapularis And Ixodes Pacificus (Acari: Ixodidae) In The Contiguous United States, Micah B. Hahn, Catherine S. Jarnevich, Andrew J. Monaghan, Rebecca J. Eisen

Entomology Papers from Other Sources

In addition to serving as vectors of several other human pathogens, the black-legged tick, Ixodes scapularis Say, and western black-legged tick, Ixodes pacificus Cooley and Kohls, are the primary vectors of the spirochete (Borrelia burgdorferi) that causes Lyme disease, the most common vector-borne disease in the United States. Over the past two decades, the geographic range of I. pacificus has changed modestly while, in contrast, the I. scapularis range has expanded substantially, which likely contributes to the concurrent expansion in the distribution of human Lyme disease cases in the Northeastern, North-Central and Mid-Atlantic states. Identifying counties that contain …

Investigating Ichneumonidae: Insights Into Species Identification And Venom Composition, Victoria G. Pook

Theses and Dissertations--Entomology

Parasitoid wasps are hyperdiverse, with current estimates suggesting that they may account for up to 20% of all insect species. Though their ecological significance and their importance in integrated pest management cannot be denied, these taxa remain understudied and, due to their small size, are often overlooked. However, recent advances in molecular techniques are helping to reverse this trend by providing tools which scientists can use to better understand species limits and host interactions.

Parasitoid wasps are often morphologically cryptic and their accurate delimitation requires the analysis of DNA sequence data from fast-evolving genes in addition to morphological characters. The …

Evidence For Use Of Alliaria Petiolata In North America By The European Cabbage White Butterfly, Pieris Rapae, Sam L. Davis, Don Cipollini

Biological Sciences Faculty Publications

Pieris rapae L., an invasive crop pest, may have recently begun using Alliaria petiolata Bieb. (Cavara & Grande), a European invasive biennial. We investigated how P. rapae uses forest habitats for nectar and oviposition and examined larval performance on A. petiolata in the field and laboratory. Being known primarily to occupy open habitats, we found that P. rapae regularly uses forest edge habitats, most surveyed A. petiolata plants had P. rapae damage, and P. rapae successfully used both stages of A. petiolata for larval development.

Dna Barcoding Of The First Recorded American Burying Beetle, Nicrophorus Americanus, In Clark County, Arkansas, J. Kelly, T. Files, N. Reyna, B. Baley

Journal of the Arkansas Academy of Science

The American Burying Beetle (ABB), Nicrophorus americanus, is a red-listed endangered species under the Endangered Species Act (16 U.S.C. 1531 et seq.). We serendipitously recorded 3 individuals of this species during a forensic study in the summer of 2013. These specimens represent the first known records for Clark County, AR and the southeastern-most record in the State since the extirpation of the species from the region in the late 1800’s. Two males and one female were collected, photographed, sexed and measured. One male specimen was deceased upon discovery. The remaining two individuals were released. The U.S. Fish and Wildlife Service …

Biogeographical Patterns In The Hard-Tick Genus Amblyomma Koch 1844 (Acari: Ixodidae), Matthew H. Seabolt

College of Graduate Studies: Theses & Dissertations

Amblyomma Koch is a genus of hard-ticks with approximately 130 species. Its geographical range is typical for organisms with a Gondwanan origin. A majority of these species are endemic to the Neo- and Afrotropical regions, with the remaining taxa dispersed throughout Southeast Asia, Australia and the Pacific islands. Based on this distribution, we hypothesize that the genus dispersal patterns will mirror the fragmentation and continental drift of the Gondwanan supercontinent. Maximum parsimony, maximum likelihood, Bayesian inference and node-dating analyses of nuclear 18S rDNA gene sequences reveal a more recent origin and radiation patterns within the genus and suggest that Amblyomma …

Effects Of Olfactory Cues On The Movement Behavior Of The Predatory Beetle Calosoma Wilcoxi, Kennesha Myrick-Bragg

Theses and Dissertations

Arthropod predators often use prey and conspecific cues to make foraging decisions. Calosoma wilcoxi (Leconte) is a voracious predatory beetle that specializes on lepidopteran larvae often found in the forest canopy, including the fall cankerworm. This study tested the hypothesis that C. wilcoxi uses olfactory cues to detect prey and conspecifics. A Y-tube olfactometer was used to test attractiveness to larvae, larval frass, conspecific cues, and volatiles from herbivore-damaged white oak leaves. C. wilcoxi did not preferentially choose the treatment in any of the experiments. There was no difference in mean time spent in the treatment or control arm for …

A Phylogenetic Investigation Of The Spittlebug Superfamily Cercopoidea (Insecta: Hemiptera: Auchenorrhyncha) With Emphasis On The Family Machaerotidae, Adam Jorgensen Bell

Legacy Theses & Dissertations (2009 - 2024)

The superfamily Cercopoidea (Insecta: Hemiptera: Auchenorrhyncha) represents a relatively small insect lineage with just over 2600 species in five described families. Known as spittlebugs, these xylem feeding insects have the unique habit of their nymphs building a frothy matrix of partially digested, excreted plant sap and air bubbles in which they seclude themselves. Despite the size of the superfamily, the phylogenetic relationships among the described families and even the total number of families are still being debated.

Influence Of Structural Disturbance On Stream Function And Macroinvertebrate Communities In Upper Coastal Plain Headwater Streams, Richard Andrew Biemiller

Theses and Dissertations--Entomology

Freshwater is a resource under threat due to anthropogenic actions. Stream restoration is a common method for mitigating disturbance. Inconsistent methodologies used for evaluating restorations have drawn criticism. Limited use of baseline data for guiding stream restoration activities is of particular concern. This study was developed to elucidate metrics that differentiate reference and disturbed sites in Upper Coastal Plain streams. This information could improve resource use and successes of restorations. Structural and functional variables were examined in 10 reference and 10 streams that meet the traditional definition of disturbance and would be restoration priorities. Disturbed streams were classified into two …

Subacute Effects Of Prallethrin On Behavior Of Mosquitoes (Diptera: Culicidae) And Other Human Disease Vectors, Kyndall C. Dye

Theses and Dissertations--Entomology

The synthetic pyrethroid, prallethrin, is an active ingredient in a widely marketed ultralow volume (ULV) mosquito adulticide. Volatilized prallethrin is intended to stimulate mosquito flight, increasing overall effectiveness of the adulticide. However, field tests using volatilized prallethrin did not produce significant differences in various vector trap catches, suggesting prallethrin’s behavioral effects are not viable. Laboratory tests were conducted to evaluate prallethrin’s effect on flight behavior of adult female Asian tiger mosquitoes (Aedes albopictus). Mosquitoes were divided into three groups; a control, those exposed to volatilized prallethrin, and those exposed to a simulated ULV application at label rates. After …

Effects Of Landscape, Intraguild Interactions, And A Neonicotinoid On Natural Enemy And Pest Interactions In Soybeans, Hannah J. Penn

Theses and Dissertations--Entomology

Demand for food, fuel, and fiber has been increasing, escalating the intensification of agriculture during the past fifty years. A more comprehensive understanding of the impact of landscapes on sustainable agriculture production is required to meet the continual increase in human demand. This not only includes how chemical inputs are used but also how cultivated and surrounding landscapes are managed for ecosystem services. This research explains how land cover on landscape and farm scales impact ant and spider-mediated pest suppression. I successfully developed and optimized molecular methods to test ant gut contents from both laboratory and field-caught specimens. A multi-year …
