Molecular Characterization Of Wolbachia And Its Impact On The Microbiome Of Exotic And United States Ticks, Cailyn G. Bobo May 2020

Molecular Characterization Of Wolbachia And Its Impact On The Microbiome Of Exotic And United States Ticks, Cailyn G. Bobo

Honors Theses

Wolbachia endosymbionts are obligate intracellular bacteria in the phylum α-Proteobacteria. They infect approximately two-thirds of arthropods including insects and nematodes. These bacteria manipulate host reproductive biology through a series of mechanisms that include feminization of male progeny, parthenogenesis, male killing, and cytoplasmic incompatibility. These features make Wolbachia an effective agent of controlling insect populations, as previously reported in different mosquito species. Likewise, the bacteria have also shown promising ability to interfere with the ability of mosquitoes to transmit several viral pathogens. This study was conducted to fill an existing knowledge gap on the prevalence of Wolbachia in different tick species …


Effects Of Acorns On Populations Of Aedes Mosquitoes, Rachel Rogers May 2018

Effects Of Acorns On Populations Of Aedes Mosquitoes, Rachel Rogers

Honors Theses

Aedes albopictus (Asian tiger mosquito) and Aedes aegypti (yellow fever mosquito) are two mosquito species that are non-native to North America and are of medical importance. Both species can be found in aquatic container habitats, such as discarded tires and tree holes. In container habitats, the influx of detritus from the outside environment is essential to mosquito production and can include a variety of plant and animal material. Seeds from oak trees (acorns) can seasonally contribute to the detritus of these container habitats. This study examined the effect of acorns from the southern live oak (Quercus virginiana) on the performance …


Expression Of Glycine-Rich Proteins Found In Salivary Glands Of The Lone Star Tick (Amblyomma Americanum) Using A Mammalian Cell Line, Annabelle Clark Dec 2016

Expression Of Glycine-Rich Proteins Found In Salivary Glands Of The Lone Star Tick (Amblyomma Americanum) Using A Mammalian Cell Line, Annabelle Clark

Honors Theses

Ticks play an important ecological role as well as a growing role in human health and veterinary care. Ticks are hosts to a plethora of microbial pathogens that can be transferred during feeding to cause tick-borne diseases in humans and many animals. Ticks may in large part owe the success of the transfer of these pathogens between hosts to their complex saliva. The saliva secreted upon a tick’s attachment to a host serves the following, among other, functions: anti-hemostasis of the blood pool, preventing an inflammatory response at the bite site, and serving as a natural anti-microbial substance. An important …


The Uas-Gal4 System In D. Melanogaster: An Insight Into The Influence Of Micrornas On The Developmental Pathways Of The Wing, Emily R. Wilson May 2016

The Uas-Gal4 System In D. Melanogaster: An Insight Into The Influence Of Micrornas On The Developmental Pathways Of The Wing, Emily R. Wilson

Honors Theses

By examining genetic pathways in D. melanogaster, a better understanding of the homologous regulatory mechanisms in humans can be utilized to further enhance knowledge of the roles of microRNA within development. This study utilizes the UAS-Gal4 system in order to produce a mutant phenotype capable of being visually studied and analyzed, focusing on the developmental pathway of the wing in D. melanogaster. Dissections of the wandering third instar larvae yielded wing disc tissue expressing the downregulation of loquacious and CG17386.
