Estimating Parasitism Of Colorado Potato Beetle Eggs, Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae), By Edovum Puttleri (Hymenoptera: Eulophidae), E. Groden, F. A. Drummond, R. A. Casagrande, J. H. Lashomb

The Great Lakes Entomologist

A computer simulation was used to evaluate methods for estimating parasitism of Colorado potato beetle egg mass populations by Edovum puttleri. The algorithm incorporated the specific attack behavior of E. puttleri, and a development time for parasitized egg masses of ca. 2.9 times that of healthy egg masses. Of the methods compared, a modification of Southwood's graphical technique was found to be most accurate in relation to the true parasitism derived from the algorithm. A regression equation is presented to correct the error in this method at high levels of parasitism. A second simulation was used to test the accuracy …

Late Lilac, Syringa Villosa: New Host Of The Lace Bug Leptoypha Mutica (Heteroptera: Tingidae), A. G. Wheeler Jr.

The Great Lakes Entomologist

The lace bug Leptoypha mutica, a specialist on trees and shrubs of the Oleaceae, feeds mainly on ash, Fraxinus spp., and fringetree, Chionanthus virginicus. In July 1987 and 1988, nymphs and adults were observed on late lilac, Syringa villosa, in a landscape planting in northwestern Pennsylvania. Infested leaves showed chlorotic blotches, the damage concentrated around midribs and lateral veins. This is the first report of lilac serving as a host for a North American tingid.

Insect Pests Associated With Birdsfoot Trefoil, Lotus Corniculatus, In Wisconsin, Mark S. Wipfli, John L. Wedberg, David B. Hogg, Thomas D. Syverud

The Great Lakes Entomologist

Insect surveys taken during 1984-1986 in Ashland and Bayfield Counties of northern Wisconsin revealed that several potential insect pest species were common in birdsfoot trefoil, Lotus corniculatus. Three plant bug species, including: the tarnished plant bug, Lygus lineolaris: alfalfa plant bug, Adelphocoris lineolatus; and Plagiognathus chrysanthemi were abundant in most sampled fields. P. chrysanthemi was the most abundant species, was only present in the northern locations, and completed one generation per year. A. lineolatus and L. lineolaris were second and third in abundance, respectively, and completed two generations per year. Population levels of the potato leafhopper, Empoasca fabae. …

Bacteria As Ovipositional Attractants For Aedes Aegypti (Diptera: Culicidae), Dana Hasselschwert, C. Lee Rockett

The Great Lakes Entomologist

The effectiveness of selected bacterial species as ovipositional attractants for Aedes aegypti was compared. Bacterial washes, in glass containers, were utilized as ovipositional substrates and subsequent egg counts determined the degree of ovipositional attractiveness. Among others, Bacillus cereus and Pseudomonas aeruginosa were noted as being effective attractants. It was concluded that A. aegypti displays discriminatory behavior in selecting individual bacterial species for oviposition.

Attraction Of Acorn-Infesting Cydia Latiferreana (Lepidoptera: Tortricidae) To Pheromone-Baited Traps, J. W. Peacock, S. L. Wright, J. R. Galford

The Great Lakes Entomologist

Males of acorn-infesting Cydia latiferreana are attracted to an equilibrium mixture of the four isomers of 8, 10-dodecadien-l-ol acetate, the virgin female-produced pheromone. Trap height relative to the height of trees in which traps are placed seems to be a significant factor influencing moth catches at attractant-baited traps. In an oak woodlot and in an oak nursery, catches of male moths were greater in traps placed near the upper periphery of the canopy than at traps deployed at lower levels in the tree. Practical application of pheromone-baited traps in a forest situation will require further study on lure formulation and …

Targeting Cancer Stem Cells In Recurrent Lung Cancer, Karen T. Udoh

Posters-at-the-Capitol

Lung cancer is the leading cause of cancer mortality in the world. Five-year survivability still remains dismal due to drug resistance. The development of drug resistance with cisplatin or platinum/taxane combination chemotherapies has led patients to suffer from recurrent lung cancer. These chemotherapy treatments target cancer cells but leave behind cancer stem cells. Cancer stem cells (CSCs) are stem-like tumor cells that have the potential to differentiate, self-renew, and proliferate. This allows the cancer to relapse even after initial elimination of the tumor. We hypothesize that Verrucarin J will inhibit cell proliferation in lung cancer cells and CSCs by inducing …

Posters-at-the-Capitol

Farming practices such as no tillage and plowing can institute change on soil physical and chemical characteristics. In this research, the effects of long-term conventional and no-tillage systems on the selected soil properties were determined in a continuous corn system on a farm with Maury silt loam soil. These samples were taken from University of Kentucky's Research Farm (Spindletop Farm). The field used was tilled in 1969 from bluegrass sod and the first time research was conduced was in 1970. Each plot is 20 ft. by 40 ft. and for many years each plot was split with winter cover crop …

Achilles Is A Circadian Clock-Controlled Gene That Regulates The Immune System And Its Rhythmicity In Drosophila, Jiajia Li

Dissertations

Circadian clock is a transcriptional/translational feedback loop that drives the rhythmic expression of downstream mRNAs. Termed “clock-controlled genes,” these molecular outputs of the circadian clock orchestrate cellular, metabolic, and behavioral rhythms. As part of our on-going work to characterize key upstream regulators of circadian mRNA expression, we have identified a novel clock-controlled gene in Drosophila melanogaster, Achilles (Achl), which is rhythmic at the mRNA level in the brain and represses expression of immune response genes, especially anti-microbial peptides in the immune system. Achl knock-down in the brain dramatically elevates expression of crucial immune response genes, including IM1 …

Spiritual Resilience In American Older Women, Cadence R. Duke

Psychology Undergraduate Work

Abstract

The study explores the phenomenology of spiritual resilience, the essence of participants’ lived experience, and the meaning of spiritual resilience in participants’ lives. Previous studies have shown various definitions and determinants of resilience and spiritual resilience. Five older women associated with the Pentecostal denomination were interviewed, audio recorded, and then transcribed for analysis. These interviews were organized and set into varying categories and qualitatively analyzed based on themes, meanings, experiences, and definitions. Participants defined spiritual resilience as only possible by one’s personal day to day relationship with God. The determinants of spiritual resilience can be summarized as the focus …

Marine & Environmental Sciences Faculty Datasets

The continental shelf off Florida’s west coast is a mosaic of fish habitats including seagrass beds and carbonate reef outcroppings (hard bottom) classified by the National Marine Fisheries Service (NMFS) as Essential Fish Habitat. Habitat maps and community baseline data, however, are nonexistent for a majority of the region. This collaborative effort between Nova Southeastern University, Florida Fish and Wildlife Conservation Commission, NMFS and other scientists will characterize and map continental shelf seagrass and hard bottom habitats in nearshore areas fished by many recreational fishermen. Objectives include: 1) map hard bottom and seagrass beds using various data types including sonar …

Transcriptional Alterations In Hereditary And Sporadic Nonfunctioning Pancreatic Neuroendocrine Tumors According To Genotype., Xavier M Keutgen, Suresh Kumar, Sudheer Gara, Myriem Boufraqech, Sunita Agarwal, Ralph H Hruban, Naris Nilubol, Martha Quezado, Richard Finney, Maggie Cam, Electron Kebebew

Surgery Faculty Publications

BACKGROUND

Nonfunctioning pancreatic neuroendocrine tumors (NFPanNETs) may be sporadic or inherited because of germline mutations associated with von Hippel-Lindau disease (VHL) or multiple endocrine neoplasia type 1 (MEN1). The clinical behavior of NFPanNETs is difficult to predict, even in tumors of the same stage and grade. The authors analyzed genotype-specific patterns of transcriptional messenger RNA (mRNA) levels of NFPanNETs to understand the molecular features that determine PanNET phenotype.

METHODS

Thirty-two samples were included for genome-wide mRNA gene expression analysis (9 VHL-associated, 10 MEN1-associated, and 9 sporadic NFPanNETs and 4 purified normal islet cell [NIC] samples). Validation of genes was performed …

Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen

HCNSO Student Theses and Dissertations

The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …

A Metabolic Hypothesis For The Evolution Of Temperature Effects On The Arterial Pco2 And Ph Of Vertebrate Ectotherms, Stanley S. Hillman, Michael Scott Hedrick

Biology Faculty Publications and Presentations

Body temperature increases in ectothermic vertebrates characteristically lead to both increases in arterial PCO2 (PaCO2) and declines in resting arterial pH (pHa) of about 0.017 pH units/°C increase in temperature. This ‘alphastat’ pH pattern has previously been interpreted as being evolutionarily-driven by the maintenance of a constant protonation state on the imidazole moiety of histidine protein residues, hence stabilizing protein structure-function. Analysis of the existing data for interclass responses of ectothermic vertebrates show different degrees of PaCO2 increases and pH declines with temperature between the classes with reptiles>amphibians>fish. The PaCO2 at the temperature where maximal aerobic metabolism (VO2max) …

Comparison Of Lithium-Ion Anode Materials Using An Experimentally Verified Physics-Based Electrochemical Model, Rujian Fu, Xuan Joe Zhou, Hengbin Fan, Douglas Blaisdell, Ajay Jagadale, Xi Zhang, Rui Xiong

Electrical & Computer Engineering Publications

Researchers are in search of parameters inside Li-ion batteries that can be utilized to control their external behavior. Physics-based electrochemical model could bridge the gap between Li+ transportation and distribution inside battery and battery performance outside. In this paper, two commercially available Li-ion anode materials: graphite and Lithium titanate (Li4Ti5O12 or LTO) were selected and a physics-based electrochemical model was developed based on half-cell assembly and testing. It is found that LTO has a smaller diffusion coefficient (Ds) than graphite, which causes a larger overpotential, leading to a smaller capacity utilization and, correspondingly, a shorter duration of constant current charge …

Targeting The Bacterial Orisome In The Search For New Antibiotics, Julia E. Grimwade, Alan C. Leonard

Biomedical Engineering and Sciences Faculty Publications

There is an urgent need for new antibiotics to combat drug resistant bacteria. Existing antibiotics act on only a small number of proteins and pathways in bacterial cells, and it seems logical that expansion of the target set could lead to development of novel antimicrobial agents. One essential process, not yet exploited for antibiotic discovery, is the initiation stage of chromosome replication, mediated by the bacterial orisome. In all bacteria, orisomes assemble when the initiator protein, DnaA, as well as accessory proteins, bind to a DNA scaffold called the origin of replication (oriC). Orisomes perform the essential tasks of unwinding …
