Investigation Of Insect-Weed Interactions In The Rice Agroecosystem, Kelly V. Tindall

LSU Doctoral Dissertations

Interactions between graminaceous weed and insect pests of rice and between management practices for these pests were investigated. Studies were conducted to examine preference and performance of rice water weevil, Lissorhoptrus oryzophilus Kuschel, on several weeds commonly found in rice fields. Several weeds were more preferred than rice, and larvae were present on several dicotyledonous weeds, suggesting the host range of L. oryzophilus is broader than previously thought. Effects of the presence of barnyardgrass, (Echinochloa crus-galli Beauv.), on rice stink bugs, Oebalus pugnax F., and L. oryzophilus populations in rice fields were investigated. Presence of barnyardgrass and the synchrony …


The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier Jan 2004

The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier

LSU Doctoral Dissertations

Behavior modification and medication have been proven to be the most effective interventions for children with ADHD. For these treatments to be effective, utilization of mental health care services as well as compliance with treatment recommendations is necessary. There has been shown lower care utilization among minorities for the treatment of behavioral disorders. In addition, lack of adherence among these populations to ADHD treatment is not explained by SES, parenting stress, or family coping. An alternative explanation may be parental knowledge of ADHD and opinions of commonly used treatments. The present investigation examined the effect of a brief knowledge intervention …


A New Broad Spectrum Disinfectant Suitable For The Food Industry, Giovanna Aita Dequeiroz Jan 2004

A New Broad Spectrum Disinfectant Suitable For The Food Industry, Giovanna Aita Dequeiroz

LSU Doctoral Dissertations

A unique biocide composition (patent pending) that is formed from a hydrogen peroxide and sodium hypochlorite mixture was investigated. A biocidal "complex" is formed by adding the peroxide to the hypochlorite in an amount so that the weight ratio of the peroxide to the hypochlorite is no less than 1:10. The chemical structure of this biocidal "complex" is uncertain but we postulate that it is a semi-stable complex, whose stability is disrupted by heat, acid, U/V exposure and the presence of organic matter (i.e., microbes) The antimicrobial activity of the biocidal "complex" is most likely a combination effect between oxidation …

Physicochemical And Functional Properties Of Crawfish Chitosan As Affected By Different Processing Protocols, Sun-Ok Fernandez-Kim

LSU Master's Theses

Chitosan is made from chitin by a chemical process involving demineralization (DM), deproteinization (DP), decolorization (DC), and deacetylation (DA). Very little work has been done to demonstrate the effects of altering or excluding any of the processing steps on chitosan characteristics. The present study was undertaken to evaluate the effects of process modification during chitosan production on the physiochemical and functional properties of crawfish chitosans. Five experimental chitosan samples (DCMPA, DMCPA, DMPCA, DMPAC, DAMPC) prepared with modified processing protocols and the control (DPMCA - traditional chitosan production process) were evaluated and compared with the two commercial crab chitosans. All samples …


"Walking The Queen's Highway": Ideology And Cultural Landscape In Nothern Ireland, Deborah J. Miller Jan 2004

"Walking The Queen's Highway": Ideology And Cultural Landscape In Nothern Ireland, Deborah J. Miller

LSU Doctoral Dissertations

The use of public art and ritual in Northern Ireland leads to the creation of cultural landscapes heavy with symbolism – ideological landscapes – that maintain social divisions and incite conflict. Mural and curbstone painting, flag bearing, the construction of memorials, and parading are activities that inscribe messages in the landscape. This study documents the types of symbolism prevalent in Northern Irish landscapes, the meanings attributed to them, and the reactions and subsequent cultural landscape re-creations that result. Loyalist and nationalist marches that incite riots and civil disorder have disrupted and delayed peace efforts in Northern Ireland for decades. Both …

Feeding Ecology And Morphometric Analysis Of Paddlefish, Polyodon Spathula, In The Mermentau River, Louisiana, Nicole Adele Smith

LSU Master's Theses

Little is known about the morphometrics and the feeding ecology of paddlefish in Louisiana. I examined the morphometrics and feeding ecology of paddlefish from the Mermentau River, Louisiana from March 2002 to February 2003. Paddlefish were examined morphometrically by taking measurements of eye-fork length (EFL), body cavity length (BCL), girth (G), vent girth (VG), mouth vertical (MTB), mouth horizontal (MSS), and mouth gullet bottom (MGB) to determine which parameters would give a better estimate of weight (W). Regression analysis resulted in a morphometric model of the form: logW = 10.10 + 1.52 (logEFL) + 1.21 (logG) + 0.24 (logVG) (r2 …

Development Of Chicken Polyclonal And Mouse Monoclonal-Based Enyzyme Immunoassays For The Detection Of Β-Cyclocitral In Catfish Pond Water, Cate Nakaweesa Munene

LSU Doctoral Dissertations

The Catfish industry faces a problem of off-flavors due to odorous compounds produced by cyanobacteria and blue-green algae. Beta-Cyclocitral imparts a hay-woody odor to pond water and fish tissues. At present there are no reliable pond treatment methods available to control these off-flavors. To monitor the levels of this compound for quality control, rapid, sensitive and inexpensive methods are needed. The major goal of this study was to develop enzyme-linked immunoflow assays based on monoclonal and polyclonal antibodies that are specific and sensitive enough to detect beta-cyclocitral in catfish pond water. Beta-Cyclocitral-PPD conjugate was prepared and used to immunize two …


Studies Of Ergot Alkaloid Biosynthesis Genes In Clavicipitaceous Fungi, Caroline Machado Jan 2004

Studies Of Ergot Alkaloid Biosynthesis Genes In Clavicipitaceous Fungi, Caroline Machado

University of Kentucky Doctoral Dissertations

Neotyphodium species, endophytic fungi associated with cool-season grasses, enhance host fitness and stress tolerance, but also produce biologically active alkaloids including ergot alkaloids associated with fescue toxicosis in grazing animals. One approach to reduce fescue toxicosis is to manipulate genes in the ergot alkaloid pathway. The gene, dmaW, encoding the first pathway-specific step in ergot alkaloid biosynthesis, was cloned previously from Claviceps spp. and its function was demonstrated by expression in yeast. Putative homologs have been cloned from Neotyphodium coenophialum (from tall fescue) and Neotyphodium sp. Lp1 (from perennial ryegrass). In order to confirm the function of dmaW in ergot …

The attractiveness of seven methyl esters of L-isoleucine and L-valine blends to P. ephilida males was evaluated in sweet potato fields in 1999 and 2000. The 100% methyl ester of L-isoleucine was significantly more attractive than all other blend ratios that were tested. The life cycle of P. …


Site-Directed Mutagenesis Studies Of E. Coli Biotin Carboxylase, Valerie Melissa Sloane Jan 2004

Site-Directed Mutagenesis Studies Of E. Coli Biotin Carboxylase, Valerie Melissa Sloane

LSU Doctoral Dissertations

Acetyl-CoA carboxylase is an essential enzyme in all plants, animals, and bacterie, where it catalyzes the committed step in fatty acid synthesis. The Escherichia coli version of the enzyme has three functional components that dissociate readily: biotin carboxylase, carboxyltransferase, and a biotin carboxyl carrier protein. The biotin carboxylase component catalyzes the ATP-dependent carboxylation of biotin, using bicarbonate as the carboxylate source. Biotin carboxylase is a member of a functionally diverse superfamily of proteins known as the ATP-grasp enzymes. In the first study, four residues of biotin carboxylase, Lys 116, Lys 159, His 209, and Glu 276, were selected for site-directed …

Epibiont Guilds As Paleoecological Tools In Environmental Analysis: An Example From Modern And Ordovician Shell Substrates, Stacy M. Boore Jan 2004

Epibiont Guilds As Paleoecological Tools In Environmental Analysis: An Example From Modern And Ordovician Shell Substrates, Stacy M. Boore

Honors Papers

Paleocommunities of encrusting organisms exhibit characteristics that allow comparisons of modern and fossil systems and subsequent environmental analyses. Encrusting organisms attach to a substrate that is generally limited in area. Interactions between bionts and the host organism, and bionts and the environment, are preserved on epibiont encrusted fossils. Modern biont communities from known environments can be compared to fossil biont communities in order to determine the ancient environment experienced by that fossil. Using epibionts as a tool in paleo-environmental analyses employs the somewhat problematic idea that the present can be used as a key to the past. I suggest that …
