Blow Fly (Diptera: Calliphoridae) Responses To Different Colors Of Baited Traps, Oluwadamilola Olufunso Oke

Honors College Theses

Blow flies (Diptera: Calliphoridae) are usually the first insects to colonize human remains. By determining the time of colonization, a postmortem interval (PMI), or “time of death”, can be estimated. To develop more accurate PMI estimates, it is important for forensic entomologists to understand the cues that Blow flies use to locate vertebrate remains. The purpose of this study was to determine whether Blow flies use visual cues, in addition to olfactory cues, to locate carrion. Two colors of fly traps, clear and green, were constructed and chicken gizzard used as bait. Three Blow fly species exhibited a significant preference …

The Red Imported Fire Ant: The Visitor Who Wouldn’T Leave. A Brief Overview Of The Control Of Solenopsis Invicta In The United States, Melissa Brown

Department of Entomology: Distance Master of Science Projects

The ease at which people, plants and animals move across the globe has created the perfect vehicle for transporting pests and disease. The introduction of non-native species into an ecosystem is a cause for great concern. The economic impact alone makes this a situation that effects everyone. The Red Imported Fire Ant, Solenopsis invicta Buren has become a major agricultural and urban pest throughout the southeastern United States. In addition, fire ants cause both medical and environmental harm (Stimac and Alves 1994). The cost associated with the control of the RIFA is significant. An estimated cost of about $36 per …

Rag1 Soybean Photosynthetic Response To Biotype 2 Aphid Colonization And Feeding, Katy Hillard

Department of Entomology: Distance Master of Science Projects

Over the past ten years, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), has been one of the principal insect threats to commercial soybean, Glycine max (L.) Merr., production in the United States. Resistance genes identified from native soybean have been incorporated into commercial varieties to provide protection against aphid feeding damage. The biology of the pest lends itself to rapid buildup of biotypes capable of overcoming host plant resistance. Single gene resistance sources have displayed low levels of durability against aphids. The first aphid resistant commercial soybean line released in the United States contained the Rag1 gene, which was …

Use Of Baited Attract And Kill Stations As Ipm Alternative To Control Invasive Drosophila Suzukii Matsumura (Spotted Wing Drosophila), Timothy Lampasona

Department of Entomology: Distance Master of Science Projects

The newly invasive Drosophila suzukii Matsumura (Spotted Wing Drosophila, SWD) is an economically significant pest of berries and other small fruit in the Northeast United States. Methods of controlling this insect typically consist of frequent sprays of conventional insecticide, often with long pre-harvest intervals. This experiment is intended to determine the efficacy of a unique Attract and Kill (AtK) design using super-absorbent gelatinous media saturated with highly attractive SWD bait adhered to durable netting, sprayed regularly with a range of insecticides. Our lab and field studies determined that presence of AtK stations treated with insecticides placed in vicinity of raspberries …

Pest Management: The Historical Management And Developed Resistance Of Western Corn Rootworm, Insect Resistance Management, And The Future Of Control, Mollie Mcmahon

Department of Entomology: Distance Master of Science Projects

Western corn rootworm, Diabrotica virgifera virgifera Le Conte, is a corn pest in the United States that has demonstrated overwhelming success an overcoming pest management strategies. Whether it is cultural, chemical, or transgenic control, western corn rootworm has managed to adapt, develop resistance, and create chaos among farmers and agriculture industries. Insect Resistance Management is a component of the Environmental Protection Agency and the Excellence Through Stewardship global organization. The Environmental Protection Agency regulates resistance through laws and regulations and with the help of other government organizations. The goal is to delay resistance, extend trait durability, and protect the environment …

A Guidebook On Honey Bee Health: Honey Bee Immunity — Pesticides — Pests And Diseases, Joey Caputo

Department of Entomology: Distance Master of Science Projects

Pedigo and Rice (2009) described a concept that some ecologists subscribe to called the “balance of nature” phenomenon. This idea holds that spe-cies in communities achieve certain status in their ecosystem and that this status becomes fixed and resistant to change. On average, individuals are only able to replace themselves. Fluctuations may occur, but ultimately the various species in the community will retain their position and relative population size in the ecosystem. According to these ecologists, when humans alter and reduce the diversity of an ecosystem they are acting counter to this balance. In an attempt to re-turn the altered …

Aquatic Insect Community Structure And Secondary Production In Coastal Wetland Ponds Of The Copper River Delta, Alaska: Influence Of Water Temperature And Macrophyte Community Structure, Chantel Caldwell

Master's Theses

The Copper River Delta (CRD), southcentral Alaska, is one of the world’s largest continuous coastal wetlands and is largely composed of sloughs, lakes, and ponds. Due to coastal topography the east side of the Copper River (East Delta) is disproportionately impacted by a cold continental air mass. Wetland communities of the CRD were also impacted by a 9.2 magnitude earthquake in 1964 that shifted the more coastal portion of the CRD from tidally influenced ponds to freshwater ponds.

The West-East temperature gradient across the CRD coupled with landscape type (uplifted marsh (UM) and outwash plain (OP)) creates four regions (West-UM, …

Examining The Role Of Host Use On Divergence In The Redheaded Pine Sawfly, Neodiprion Lecontei, Across Multiple Spatial Scales, Robin Kimberly Bagley

Theses and Dissertations--Biology

Phytophagous insects make up over one quarter of described species on Earth, and this incredible diversity seems directly linked to feeding on plants. Comparative studies of sister groups have shown shifts to herbivory are consistently associated with increased species diversity in insects, but the reasons for this diversification remain unclear. While other explanations, such as decreased extinction rates or influences on population structure, exist, one prominent hypothesis suggests shifts and subsequent adaptation to novel host plants can lead to the evolution of reproductive barriers.

Given their extreme specialization on host plants in the genus Pinus and intimate, life-long association with …

The Xenobiotic Transcription Factor Cap N Collar C Regulates Expression Of Multiple Insecticide Resistant Genes, Megha Kalsi

Theses and Dissertations--Entomology

Insecticide resistance is a global problem. Insecticide resistance management is very important, considering the time, effort, and cost of discovering and developing a new insecticide. There are diverse resistance mechanisms, but enhanced detoxification through overexpression of cytochrome P450s and target site insensitivity through mutation in insecticide binding site are the two most common mechanisms. The xenobiotic detoxification is divided into three successive phases (I, II and III), which ensures the metabolism and excretion of the detrimental toxins. Each phase comprises of a specific group of metabolizing enzymes such as P450s (phase I), GSTs (phase II) and ABC transporters (phase III). …

Exploring Predator-Prey Interactions In Agroecosystems Through Molecular Gut-Content Analysis, Kacie J. Athey

Theses and Dissertations--Entomology

Generalist predators can contribute to vital ecosystem services by potentially inducing trophic cascades as natural enemies of pests in agroecosystems. As the human population of the world gets larger, we need to produce more food on ever-smaller swaths of available land relying on ecosystem services, in the form of pest control, that may contribute to agricultural sustainability. Teasing apart the exact trophic linkages between predators and prey is a vital first step and essential to uncovering which predators are inducing trophic cascades and should be enhanced through conservation biological control.

Combined with ecological experimentation, the main tool used throughout my …

Evaluation Of Pyriproxyfen Applied In Barrier Sprays For Mosquito Suppression, Andrea Glenn Skiles

Theses and Dissertations--Entomology

Despite advances in mosquito management, mosquito-borne disease in the United States is still of relevant public health concern and vector control is a top priority in preventing transmission of pathogens. Insecticide barrier sprays have become a common tool for suppression of mosquitoes in single-homeowner backyards. The application of the synthetic pyrethroid, lambda-cyhalothrin to perimeter vegetation with a backpack sprayer has been shown to significantly suppress mosquito levels for around 6 weeks. In an attempt to lengthen the effective duration of treatment, the IGR, pyriproxyfen, was added to a backpack mist blower with lambda-cyhalothrin, as adult mosquitoes exposed to pyriproxyfen have …

Binding, Protection, And Rna Delivery Properties Of Porous Silica Nanoparticles In Spodoptera Frugiperda Cells, Emily Nadeau

Theses and Dissertations--Entomology

Traditional methods of pest control are threatened by the development of insecticide resistance, both to traditional insecticides and Bt toxins. Discovery of RNA interference (RNAi) has created opportunities to develop new insect control mechanisms. However, RNAi responses appear to be robust in coleopteran pests, but other orders, e.g. Lepidoptera and Hemiptera, present varied or ineffective RNAi responses. Current delivery strategies for double-stranded RNA (dsRNA) include microinjection, ingestion, and soaking. These approaches have benefits and problems. This study investigates the potential for porous silica nanoparticles (pSNPs) to improve the delivery of dsRNA and induce an RNAi response in Spodoptera frugiperda cells. …
