Characterization Of Hessian Fly From Israel, Alisha J Johnson
Characterization Of Hessian Fly From Israel, Alisha J Johnson
Open Access Dissertations
Mayetiola destructor Say, the Hessian fly, is a gall midge and a member of the Dipteran family Cecidomyiidae. It is a common pest of wheat found throughout all of the major wheat growing areas of the world and poses a serious economic threat to the United States (US), particularly in the Southeast winter wheat region. Damage to wheat is done solely by feeding first and second in-star larvae. Hessian fly (Hf) infestations result in a loss in grain yield by the stunting and/or killing of seedling wheat plants in the winter and by causing breakage at the nodes of the …
Identification, Description, And Activity Of Proteins In The Tergal Glands Of The German Cockroach, Blattella Germanica (L.), Aaron Myers
Open Access Theses
German cockroaches are important urban pests that have been linked to asthma and serious allergic reactions in sensitized individuals. In this research project I, (i) identified different proteins expressed in the tergal glands of male German cockroaches, (ii) determined the expression levels of these proteins in different cockroach life stages and tissues, and (iii) investigated the role of the tergal gland alpha-amylase (BGTG-1) protein. ^ Four major tergal gland proteins were separated on denaturing polyacrylamide gels. With peptide sequencing two of these proteins were identified as alpha-amylase (BGTG-1) and Blattella germanica allergen 2 (Bla g 2). Both of these proteins …
The Termite Digestome: Understanding The Digestive Physiology Involved In Lignocellulosic Biomass Degradation, Zachary John Karl
The Termite Digestome: Understanding The Digestive Physiology Involved In Lignocellulosic Biomass Degradation, Zachary John Karl
Open Access Dissertations
The purpose of this research was to advance the understanding of lower termite digestive physiology and discover potential biocatalysts that can aid in the degradation of lignocellulosic biomass. Various protein characterization and gene expression methods were used throughout this research in order to accomplish these objectives. The results of this dissertation indicate that: 1) termites and their symbionts act in a synergistic manner to degrade biomass in vitro, 2) the host fraction of the gut (i.e., foregut and midgut) is the likely site of glucose absorption, 3) the termite and its symbionts contribute specific enzymes to the digestive process, 4) …
Genetic Engineering Of Black Cherry (Prunus Serotina) For Reproductive Sterility And Insect Pest Resistance, Ying Wang
Open Access Dissertations
Black cherry (Prunus serotina Ehrh.) is one of the most valuable hardwoods for high- end cabinetry, furniture, architectural millwork, paneling, and veneer. However, the damage caused by cambial-mining insect pests triggers gummosis in black cherry, a non-specific defense response in which resinous gum is deposited at the site of injury. The gum defects dramatically decrease the yield of high-quality black cherry lumber, and the value can be reduced by as much as 90%. The goal of this project was to optimize the transformation and in vitro rooting system, and to develop transgenic black cherry for reproductive sterility and insect pest …
