Wild Type Drosophila Melanogaster Eye Pigments: Examining Absorbance Spectra And Light Sensitivity, Erin Brown, Taylor M. Delaney

A with Honors Projects

The eyes of wild type fruit flies contain various pigments that contribute to a brick red color. Chromatography techniques are used to separate and view these pigments. IN this project, the students extract and gather absorbance spectra for these pigments using three methods: eye pigment chromatography, pigment extraction and spectrophotometry, and spectrophotometry and photosensitivity. The methods are compared to determine how efficient they are at separating and extracting pigments and producing reliable results when examining absorbance spectra. To explore the photosensitivity of the pigments, we compare absorbance spectra changes to a pigment solution.

Insecticidal Seed And In-Furrow Treatment Recommendations For Soybean And Sunflower, Brady Hauswedell

Electronic Theses and Dissertations

Throughout the 2016 and 2017 growing season, field research experiments were replicated across South Dakota. Many times seed treatments are used prophylactic, which is neither good for the producers or the environment. Producers will be able to reduce production costs, if they only use a seed treatment when necessary. The purpose of the first experiment was to determine the effects of seed treatments in combination with planting date and seeding rate on soybean yield. To determine the effects, two years of field data from four eastern South Dakota locations were compared. Within each year and location we compared two planting …

Aquatic Invertebrate Community Structure, Biological Condition, Habitat, And Water Quality At Ozark National Scenic Riverways, Missouri, 2005-2014, David E. Bowles, L. W. Morrison, J. T. Cribbs

Journal of the Arkansas Academy of Science

Ozark National Scenic Riverways (OZAR) was established to protect the corridor of the Current River and its major tributary, the Jacks Fork. The Current River is one of the few remaining free-flowing rivers in the U.S., with much of its base flow coming from several large springs. To assess the biological condition of these rivers, aquatic invertebrate community structure was monitored from 2005 to 2014. Benthic invertebrate samples and associated habitat and water quality data were collected from each of nine sampling sites using a Slack-Surber sampler. The Stream Condition Index (SCI), a multimetric index that incorporates taxa richness, EPT …

Sac Lanternfly Project Summary, John Pisciotta

Sustainability Research & Creative Activities Grants Reports

The Spotted Lanternfly (SLF) is an invasive plant hopper native to China that feeds on grapes, fruit trees and various hardwoods. This exotic pest was first identified in Berks County, PA in 2014. Since then its spread has radiated into surrounding areas, devastating local crops and agriculture. The goal of this surveillance project was to locate, identify and map SLF’s preferred host-tree (Ailanthus altissima) in advance of a possible WCU infestation. The host tree, also a native of China, was imported into the US by Philadelphia botanists in the 1780s and it is known to exist within the Gordon Natural …

Soybean Aphid Biotype 4 Resistance In Soja And Soybean Plant Introductions, Sophia R. Conzemius

Electronic Theses and Dissertations

Soybean aphid, Aphis glycines Matsumura, is a major pest to soybean, Glycine max (L.) Merr. Host plant resistance is a management tactic that uses naturally occurring soybean plant defenses to limit soybean aphid pest damage. Virulent soybean aphid biotypes are able to successfully colonize on certain aphid resistant soybean. Soybean aphid biotype 4 is most virulent, overcoming all commercially available soybean aphid resistant soybeans (Rag1, Rag2, and Rag1+Rag2). Additional sources of resistance to avirulent biotypes have been identified in soja and soybean plant introductions (PIs). This study examined those resistant soja and soybean for resistance to the newly found soybean …

Hart Prairie Preserve Site Visit To Assess Aspen Health Nature Conservancy, Flagstaff, Az, Amanda Grady

Aspen Bibliography

On June 11, 2018, Amanda Grady, Entomologist, Arizona Zone, Forest Health Protection, performed a site visit to evaluate aspen health on the Nature Conservancy lands at Heart Prairie Preserve (HPP) near Flagstaff. Specifically, the evaluation was to determine whether or not the aspen within exclosures on Fern Mountain have symptoms or signs of Oystershell scale (OSS), an emergent forest pest contributing to aspen decline in northern Arizona.

Improved Insect-Proofing: Expressing Double-Stranded Rna In Chloroplasts, Julia Bally, Elane Fishilevich, Andrew J. Bowling, Heather E. Pence, Kenneth E. Narva, Peter M. Waterhouse

Department of Entomology: Faculty Publications

RNA interference (RNAi) was discovered almost 20 years ago and has been exploited worldwide to silence genes in plants and animals. A decade later, it was found that transforming plants with an RNAi construct targeting an insect gene could protect the plant against feeding by that insect. Production of double-stranded RNA (dsRNA) in a plant to affect the viability of a herbivorous animal is termed trans-kingdom RNAi (TK-RNAi). Since this pioneering work, there have been many further examples of successful TK-RNAi, but also reports of failed attempts and unrepeatable experiments. Recently, three laboratories have shown that producing dsRNA in a …

Genetics And Mechanisms Underlying Transmission Of Wheat Streak Mosaic Virus By The Wheat Curl Mite, Satyanarayana Tatineni, Gary L. Hein

Department of Entomology: Faculty Publications

Wheat streak mosaic virus (WSMV, genus Tritimovirus; family Potyviridae) is the most economically important virus of wheat in the Great Plains region of the USA. WSMV is transmitted by the eriophyid wheat curl mite (WCM), Aceria tosichella Keifer. In contrast to Hemipteran-borne plant viruses, the mode and mechanism of eriophyid mite transmission of viruses have remained poorly understood, mostly due to difficulty of working with these ~200 μm long microscopic creatures. Among eriophyid-transmitted plant viruses, relatively extensive work has been performed on population genetics of WCMs, WSMV determinants involved in WCM transmission, and localization of WSMV virions and …

The Impacts Of Honey Bee Queen Stress On Worker Behavior And Health, Sarah R. Preston

Theses and Dissertations--Entomology

Pesticides, poor nutrition, parasites and diseases work synergistically to contribute to the decline of the honey bee. Heritable sub-lethal behavior/immune effects may also contribute to the decline. Maternal stress is a common source of heritable immune/behavior deficits in many species. A stressed honey bee queen has the potential to pass such deficits on to worker bees. Using a repeated measures design, this study will determine whether the health of worker bee is reduced by a cold stress on the queen by analyzing egg hatch rate and protein content, emergence rate, and adult aggression and immune function for offspring laid before …

Absorbance Of 0.15 Seen At 440 Nm Double Peak In Sepia Eyed Drosophila Melanogaster, Fabiola Padron, Liping Zhao

Natural Sciences Student Research Presentations

This poster for the Natural Sciences Poster Session at Parkland College reports on an experiment in which the objective was to observe absorbance of eye pigments in both sepia and white eyed fruit flies. Three types of chromatography were used, paper, TLC, and 2D. It was determined that 2D Chromatography was ideal in separating blue and green pigment from sepia toned eyes in fruit flies.

Some Aspects Of Woodpecker Predation On The Spruce Beetle In Colorado, Steven R. Helm

Department of Entomology: Distance Master of Science Projects

Historic data on predation by woodpeckers, primarily the American three-toed woodpecker (Picoides dorsalis), on epidemic levels of the spruce beetle (Dendroctonus rufipennis) in Engelmann spruce (Picea engelmannii) forests of Colorado are analyzed in this report. Significant differences in beetle consumption by male and female woodpeckers as well as seasonal differences in beetle consumption by woodpeckers in general were discovered through statistical analyses. Potential ecological explanations for observed differences are discussed.
