Molecular Mechanisms Of Bacillus Thuringiensis Resistance In The Sugarcane Borer, Yunlong Yang
LSU Doctoral Dissertations
The sugarcane borer, Diatraea saccharalis, is a major target pest of transgenic corn expressing Bacillus thuringiensis (Bt) proteins in many areas of the U.S. mid-southern region. A Cry1Ab-resistant (Cry1Ab-RR) strain of D. saccharalis has been developed from a single two-parent family-line. To examine the molecular mechanisms of the Cry1Ab resistance in this insect strain, cDNAs of five types of potential candidate genes related to Bt resistance were sequenced using reverse transcriptase polymerase chain reaction (RT-PCR) and 5’ rapid amplification of cDNA end (5’ RACE). The Bt resistance candidate genes examined included three trypsins (DsTRYs), three chymotrypsins (DsCHYs), three aminopeptidases N …

Physical Activity And Health-Related Quality Of Life Among Elementary Students: An Integrated Perspective, Xiangli Gu
LSU Doctoral Dissertations
School physical education (PE) not only offers and promotes health-related physical activity, but also encompasses the promotion and development of perceptions of mental health (USDHHS, 2010). It has been suggested that health-related quality of life (HRQOL) can predict future health, monitor children’s psychosocial health, and identify those most at risk or in need of support at an early stage. Assessing physical activity (PA) and health-related quality of life have become major issues in pediatric public health and also serve as a major goal of Health people 2020 (USDHHS, 2010). Research including assessment of theory-based mediators of health-related outcomes is needed …

The Role Of Motivation And Physical Activity In A Weight Loss Program, Ellen Kane Stevens
LSU Master's Theses
Every year thousands of overweight and obese people in the United States join weight loss programs such as Weight Watchers in an effort to become healthier and feel more attractive. Weight Watchers has increased its program focus on physical activity as a critical part of weight loss. Initiating a consistent physical activity routine, however, is generally one of the last behavior changes made by program members, despite its proven role in weight loss maintenance. Using self-determination theory as a framework, the purpose of this study was to examine how perceptions of fulfillment of three psychological needs (i.e. competence, autonomy, and …

Use Of Condensed Tannins Supplementation And Inorganic Copper As Deworming Agents In Naturally Infected Ewes And Lambs, Moara De Santana Martins
LSU Master's Theses
Sheep production is an important socioeconomic activity for the small producers and it can represent their primary income source. Gastrointestinal parasites have become the principal limiting factor for this industry around the world, especially because of the anthelmintic resistance phenomenon that has been increasing worldwide. The negligent use of anthelmintics has been reported as the main factor in the development of resistance. Among the parasites that infect sheep, H. contortus is considered the most harmful and also the parasite responsible for the fastest development of nematode resistance in small ruminants. Due to the economic impact this parasite may bring upon …

LSU Doctoral Dissertations
Common salvinia, Salvinia minima Baker, is a floating aquatic invasive macrophyte that obstructs waterways and causes problems in wetlands across Louisiana and Texas. The salvinia weevil, Cyrtobagous salviniae Calder and Sands, has been released in over 14 countries around the world for the biological control of Salvinia spp. We successfully monitored the introduction and establishment of C. salviniae on S. minima in southern Louisiana between 2006 and 2010. Cyrtobagous salviniae significantly lowered the biomass of S. minima and increased the number of terminal buds damaged but had no significant impact on pH, dissolved oxygen, conductivity, surface temperature, percent of surface …
Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm
Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm
LSU Doctoral Dissertations
Core stability is a concept in the health and fitness professions which became popular in the early 1990s. Despite its popularity, core stability remains a generalized term, which is poorly understood and lacks a universal definition and gold standard assessment. This makes it difficult to identify the role of core stability in athletic injury prevention and performance. To better assess core stability, the objective for this dissertation was to construct a reliable core stability index using measurements which best define and evaluate core stability. The purpose of our first experiment was to introduce and determine the intra-tester reliability of clinical …

Agroecological Factors Impacting Stem Borer (Lepidoptera: Crambidae) Dynamics In Gulf Coast Sugarcane And Rice, Julien M. Beuzelin
LSU Doctoral Dissertations
Diatraea saccharalis (F.) and Eoreuma loftini (Dyar) are stem boring pests of sugarcane (Saccharum spp.) and rice (Oryza sativa L.) crops in the Gulf Coast region. Studies were conducted to determine the role of agroecological factors, including predator disruptions, alternate hosts, and crop phenological conditions, on stem borer populations.
The year after Hurricane Rita storm surge flooded sugarcane in Louisiana, a 71% reduction in the predaceous Solenopsis invicta Buren was recorded. Even with a 2.4-fold increase in the number of insecticide applications used for D. saccharalis management in flooded fields, growers still incurred higher injury.
In two field …
