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 …

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 …

Biodiversity Of Insect Populations In The Springfield Bog Metropark In Summit County, Ohio: A Secondary Succession Site, Cynthia Perkovich

Department of Entomology: Distance Master of Science Projects

An initiative has been taken up by many environmental agencies for the conservation and restoration of endangered wetland habitats. These unique ecosystems are being depleted of resources and acreage due to industrialization and extensive anthropogenic activities. Bogs are a unique subgroup that are diminishing worldwide. The Springfield Metropark Bog is a newly established conservation area in Summit County, Ohio, in the United States. Insect populations were recorded over four seasons, starting in March 2015 and concluding in February 2016. Samples were taken from 3 different sites within the conserved habitat including field site, forested area, and a manufactured pond. Using …

Insect Pest Introduction Into Florida: Surveillance And Detection Efforts By Government Agencies, Gangadai Azore

Department of Entomology: Distance Master of Science Projects

Today, Florida’s most important crops such as corn, peppers, and snow beans owe their existence to constant vigilance by the Florida Department of Agriculture (FDACS), United States Department of Agriculture (USDA), and Customs & Border Protection Agricultural Specialists (CBP); all three agencies work together to keep many dangerous pests out of the state. Diligent inspectors working alongside the Customs officers, meet all arriving vessels that arrive by land, sea, or air. The officers inspect cargo and passengers’ baggage, the holds of vessels, cabins, crew’s quarters, and storerooms of vessels themselves to keep out potential insects hitch-hiking on commodities or on …

Technique For: Determination Of Insect Prey Selection By Insectivorous Bats, Merrill Tawse

Department of Entomology: Distance Master of Science Projects

Utilizing Fecal Pellet Analysis to Determine Prey Selection by Insectivorous Bats: For my Graduate Project I examined culled exoskeleton parts from bat fecal pellets (guano) to determine identifications of the insects preyed upon by a group of bats to their order and often family levels. Culled insect parts were permanently fixed on microscope slides and viewed under a dissection microscope to determine identifications and to quantify the percentage composition that they represented in the bat’s diet. Comparisons were made of prey selected by the different bat species that were foraging at the same location and at the same time. Comparisons …

Investigation Into The Sex Pheromone Of The Adult Female Odd Beetle, Thylodrias Contractus Motschulsky, 1839, Patrick J. Kelley

Department of Entomology: Distance Master of Science Projects

Insects of many species depend on the chemical cues in sex pheromones to identify potential reproductive partners. Previous studies have shown that odd beetle, Thylodrias contractus utilize sex pheromones at the onset of reproductive physiology that leads to mating behavior. This is a study to make strides to identify the sex pheromone(s) for the odd beetle, T. contractus. In this study, efforts to isolate the sex pheromone of this pest insect began with observations of the mating behavior of this insect. This was followed by dissections of adult virgin females in an attempt to reveal which parts of the anatomy …

The Ins And Outs Of The Pesticide Registration Process And Why It's Important To The End-User, Linda Johns

Department of Entomology: Distance Master of Science Projects

The US EPA registration process evaluates pesticides through legal, administrative and scientific procedures that encompass the pesticide ingredients (inert and active); the crop or site pertaining to where the pesticide will be used; the amount, timing and frequency of the pesticide to be used; the disposal and storage practices for the pesticide; and the potential human health and environmental effects that could be associated with the pesticide. The US EPA evaluates and approves all label language that appears on a pesticide label, thus ensuring proper use patterns and that safety measures have been met to reduce any potential risks. All …

Active Aggregation Among Sexes In Bean Flower Thrips (Megalurothrips Sjostedti) On Cowpea (Vigna Unguiculata), Saliou Niassy, Sunday Ekesi, Nguya K. Maniania, Benedict Orindi, Gerald B. Moritz, Willem J. De Kogel, Sevgan Subramanian

All Peer-Reviewed Publications

Male sexual aggregations are a common territorial, mating-related or resource-based, behaviour observed in diverse organisms, including insects such as thrips. The influence of factors such as plant substrate, time of day, and geographic location on aggregation of thrips is uncertain, therefore we monitored the dispersion of male and female bean flower thrips (BFT), Megalurothrips sjostedti (Trybom) (Thysanoptera: Thripidae), on cowpea, Vigna unguiculata (L.) Walp. (Fabaceae), over three cowpea growth stages and across three cowpea-growing areas of Kenya. Our results indicated that for all the crop growth stages, the density of BFTs varied over the time of day, with higher densities …

Rapid And High Throughput Molecular Identification Of Diverse Mosquito Species By High Resolution Melting Analysis., Yvonne Ukamaka Ajamma, Enock Mararo, David Omondi, Thomas Onchuru, Anne W.T. Muigai, Daniel Masiga, Jandouwe Villinger

All Peer-Reviewed Publications

Mosquitoes are a diverse group of invertebrates, with members that are among the most important vectors of diseases. The correct identification of mosquitoes is paramount to the control of the diseases that they transmit. However, morphological techniques depend on the quality of the specimen and often unavailable taxonomic expertise, which may still not be able to distinguish mosquitoes among species complexes (sibling and cryptic species). High resolution melting (HRM) analyses, a closed-tube, post-polymerase chain reaction (PCR) method used to identify variations in nucleic acid sequences, has been used to differentiate species within the Anopheles gambiae and Culex pipiens complexes. We …
