Increased Survival Of Western Corn Rootworm On Transgenic Corn Within Three Generations Of On-Plant Greenhouse Selection, Lisa N. Meihls, Matthew L. Higdon, Blair D. Siegfried, Nicholas J. Miller, Thomas W. Sappington, Mark R. Ellersieck, Terrence A. Spencer, Bruce E. Hibbard

Department of Entomology: Faculty Publications

To delay evolution of insect resistance to transgenic crops producing Bacillus thuringiensis (Bt) toxins, nearby ‘‘refuges’’ of host plants not producing Bt toxins are required in many regions. Such refuges are expected to be most effective in slowing resistance when the toxin concentration in Bt crops is high enough to kill all or nearly all insects heterozygous for resistance. However, Bt corn, Zea mays, introduced recently does not meet this ‘‘high-dose’’ criterion for control of western corn rootworm (WCR), Diabrotica virgifera virgifera. A greenhouse method of rearing WCR on transgenic corn expressing the Cry3Bb1 protein was used in …

Ecological Niche Of The 2003 West Nile Virus Epidemic In The Northern Great Plains Of The United States, Michael Wimberly, Michael B. Hildreth, Stephen P. Boyte, Erik Lindquist, Lon Kightlinger

Public Health Resources

Background: The incidence of West Nile virus (WNv) has remained high in the northern Great Plains compared to the rest of the United States. However, the reasons for the sustained high risk of WNv transmission in this region have not been determined. To assess the environmental drivers of WNv in the northern Great Plains, we analyzed the county-level spatial pattern of human cases during the 2003 epidemic across a seven-state region.
Methodology/Principal Findings: County-level data on WNv cases were examined using spatial cluster analysis, and were used to fit statistical models with weather, climate, and land use variables as predictors. …

Trapping Small Hive Beetles, Aethina Tumida Murray, Inside Honey Bee Colonies, Maxcy Nolan Iv

All Theses

The small hive beetle, Aethina tumida Murray, (Coleoptera: Nitidulidae) is an economically important honey bee pest, particularly in the southeastern United States. One method of controlling this pest is the use of an in-hive trap. Many different attractants have been developed and are used in such traps. Part one of my thesis involved testing a new attractant, a pollen substitute inoculated with the yeast Kodamaea ohmeri (NRRL Y-30722). Thirty-two test colonies were established with 0.9-kg (2-lb) packages of bees with queens. Eight colonies were placed in each apiary, and colonies received one of three treatments: 1) yeast-based attractant 2) apple …

Comparison Of Caddisfly Species (Insecta:Trichoptera) In The Northern Saluda Watershed Over A Thirty-Seven Year Period, In Correlation With Land Development And Use., Michael Biondi

All Theses

Land use and development in South Carolina has greatly increased in the last 50 years. This study focused on land cover change in Northern Pickens County and changes in caddisfly populations at three sites in three sub-watersheds in the South Saluda River watershed. I collected caddisflies from March 31 to October 20 in 2005 and 2006 and compared them to collections performed at the same sites in the same manner in 1969 by John C. Morse for his Master's thesis. I used a geographic information system to assess the land cover change over this thirty-seven year period and correlated the …

Revision Of East Palearctic Apatania (Trichoptera: Apataniidae), Suvdtsetseg Chuluunbat

All Theses

The East Palearctic genus Apatania Kolenati includes 34 species. Thirty-two of these have been described as adults and the other 2 are known only in the larval life stage. Immature stages of most species are not yet known.
A morphological study of these species suggested that 2 of the nominal species are synonyms of other species, reducing the number of valid East Palearctic Apatania species to 30. A phylogeny and classification of the reviewed 30 species is provided for this work. My work does not support Schmid's (1953) groupings of Apatania species.

Reproductive Tactics Of Aphidophagous Lady Beetles: Comparison Of A Native Species And An Invasive Species That Is Displacing It, Yukie Kajita

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coccinella septempunctata L. (Coleoptera: Coccinellidae) has been introduced to North America in recent decades, raising concerns of adverse impacts on native lady beetles, including the congeneric C. transversoguttata richardsoni (Brown). The central focus of my dissertation is to understand the importance of reproduction, in particular, in promoting invasion of C. septempunctata and its replacement of native lady beetles in alfalfa fields of western North America.

Studies were conducted to compare reproductive tactics of the invasive C. septempunctata and the native C. transversoguttata, by addressing: 1) maximum rate of reproduction of overwintered lady beetles, 2) population dynamics of the invasive …

Diets Of Ladybird Beetles (Coleoptera: Coccinellidae) In Utah Alfalfa Fields, Lynette Nicole Davidson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aphidophagous lady beetles rely on multiple sources of food in their environment. Alfalfa fields provide both aphids and many alternate foods, such as other arthropod prey, pollen, and fungi. Alfalfa fields (Medicago sativa L.) in Utah have low aphid densities, which may require lady beetles to consume alternative sources of food. Many methods can be used to determine these diets; frass analysis is used here to compare the diets of the introduced species Coccinella septempunctata L. with two native species, C. transversoguttata richardsoni Brown and Hippodamia convergens Guérin-Méneville, that occur in the Utah alfalfa habitat.

In initial laboratory experiments …

Exploring The Mialome Of Ticks: An Annotated Catalogue Of Midgut Transcripts From The Hard Tick, Dermacentor Variabilis (Acari: Ixodidae), Jennifer M. Anderson, Daniel E. Sonenshine, Jesus G. Valenzuela

Biological Sciences Faculty Publications

Background: Ticks are obligate blood feeders. The midgut is the first major region of the body where blood and microbes ingested with the blood meal come in contact with the tick's internal tissues. Little is known about protein expression in the digestive tract of ticks. In this study, for analysis of global gene expression during tick attachment and feeding, we generated and sequenced 1,679 random transcripts (ESTs) from cDNA libraries from the midguts of female ticks at varying stages of feeding.

Results: Sequence analysis of the 1,679 ESTs resulted in the identification of 835 distinct transcripts, from these, a total …

Mortalités, Effondrements Et Affaiblissements Des Colonies D’Abeilles, Julie Chiron, Anne-Marie Hattenberger

Entomology Papers from Other Sources

Depuis plusieurs dizaines d’années, une diminution notoire des populations de pollinisateurs a été signalée dans de nombreux pays par les professionnels et les scientifiques. L’enjeu économique et écologique représenté par la perte de ces individus a déterminé la mise en oeuvre de nombreuses études sur le sujet. Plusieurs hypothèses de facteurs de risques ont été avancées pour tenter d’expliquer ce phénomène. En France, notamment, les apiculteurs ont alerté les pouvoirs publics quant à un effet potentiel de certains traitements phytopharmaceutiques à usage agricole sur la vitalité des colonies d’abeilles domestiques (Apis mellifera), entraînant la décision par le Ministre …

Does Repeated Burial Of Skeletal Muscle Tissue (Ovis Aries) In Soil Affect Subsequent Decomposition?, David O. Carter, Mark Tibbett

Department of Entomology: Faculty Publications

The repeated introduction of an organic resource to soil can result in its enhanced degradation. This phenomenon is of primary importance in agroecosystems, where the dynamics of repeated nutrient, pesticide, and herbicide amendment must be understood to achieve optimal yield. Although not yet investigated, the repeated introduction of cadaveric material is an important area of research in forensic science and cemetery planning. It is not currently understood what effects the repeated burial of cadaveric material has on cadaver decomposition or soil processes such as carbon mineralization. To address this gap in knowledge, we conducted a laboratory experiment using ovine ( …

Genetic Variability Of The European Corn Borer, Ostrinia Nubilalis, Suggests Gene Flow Between Populations In The Midwestern United States, Jeffrey T. Krumm, Thomas E. Hunt, Steven R. Skoda, Gary L. Hein, Donald J. Lee, Pete L. Clark, John E. Foster

Department of Entomology: Faculty Publications

The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a widely distributed and serious economic pest to corn production in the U.S. Genetic variability of O. nubilalis was studied in 18 sub-populations in the upper Midwestern United States using amplified fragment length polymorphism. The relatively low GST values indicate that more variation exists within populations than between populations. High gene flow (Nm) values were indicated across the entire O. nubilalis population; the lowest degree of gene flow was in the northern samples (Nm = 1.96) and the highest degree of gene flow was in the southern samples (Nm = …

Tb199: Ant–Homopteran Relationships: Relevance To An Ant Invasion In Maine, Katherine E. Mcphee, Eleanor Groden, Francis A. Drummond

Technical Bulletins

The richness and diversity of native ant species on Mt. Desert Island, Maine, have been reduced in areas infested with Myrica rubra (European red ant). In general, the success of invasive ant species has been attributed to interference and exploitative competition coupled with the ants’ opportunistic diets. In field experiments on Mount Desert Island, Maine, M. rubra discovered and recruited to baits faster than native ants. This study also showed that M. rubra displaced most native ant species from food resources (Garnas 2005). This, together with M. rubra’s aggressive defense of invaded territories, has led to fewer native ants in …

Familiarity With Breeding Habitat Improves Daily Survival In Colonial Cliff Swallows, Charles R. Brown, Mary Bomberger Brown, Kathleen R. Brazeal

School of Natural Resources: Faculty Publications

One probable cost of dispersing to a new breeding habitat is unfamiliarity with local conditions such as the whereabouts of food or the habits of local predators, and consequently immigrants may have lower probabilities of survival than more experienced residents. Within a breeding season, estimated daily survival probabilities of cliff swallows, Petrochelidon pyrrhonota, at colonies in southwestern Nebraska, USA, were highest for birds that had always nested at the same site, followed by those for birds that had nested there in some (but not all) past years. Daily survival probabilities were lowest for birds that were naive immigrants to …
