Knowledge, Perceptions, and Practices: Mosquito-borne Disease Transmission in Southwest Virginia
… temperate climate is suitable for several mosquito species capable of transmitting pathogens to humans. In southwest Virginia, La Crosse encephalitis and West Nile fever are most prominent. The objective of this research, which uses the Health Belief Model (HBM) as a theoretical framework, …

Mosquito-Borne Disease Prevention: Building Resilient Communities in the US-Mexico Border
Background: Mosquito-borne diseases are increasingly contributing to epidemic threats, particularly in regions like the US-Mexico border where the Aedes aegypti mosquito is expanding due to climate and socioeconomic changes. Recent outbreaks, such as the 2014 dengue surge in Yuma, Arizona, and …

Strategies for Reducing Mosquito-Borne Disease Vulnerability in Equine Populations: A Kentucky Case Study
… to the spread of West Nile virus and other mosquito-bome disease. I hypothesize that there is a relationship between equine management practices and outbreaks of mosquito-borne disease in horse populations. Improved and appropriate mosquito habitat management may limit the risk of …

Dengue Fever: An Examination and Case Study
Dengue Fever is a mosquito-borne disease found primarily in tropical regions of the Earth. Although not prevalent in much of the western world, dengue appears to be an emerging virus, which prompts a need for further understanding. The purpose of this study is to provide a general overview of the …

Short-to-medium term dengue forecast in Singapore
Dengue fever is currently the fastest spreading mosquito-borne disease in the world, and a substantial public health problem due to its geographic spread, intensity, and resulting economic impact. The disease is endemic in Singapore, and has caused multiple outbreaks of unprecedented magnitude in …

Morphological differentiation of eggs and comparative efficacy of oviposition and gravid traps for Aedes vectors at different habitats
Mosquito surveillance is an integral part of understanding mosquito-borne disease, including and not limited to the La Crosse virus. The primary container-inhabiting Aedeni vectors include Aedes triseritatus, Aedes albopictus, and Aedes japonicus. To better understand the efficacy of gravid traps …

Modeling, Dynamics and Optimal Control of West Nile Virus with Seasonality
West Nile virus (WNv) is a mosquito-borne disease which arrived in Canada in 2001. It has kept spreading across the country and still remains a threat to public health. In this dissertation, we formulate dynamical models and apply theory of dynamical systems to investigate the behavior of the …

Genetically Modifying Mosquitoes Without Compromising Fitness: Can It Be Done?
Malaria is a mosquito-borne disease caused by parasites belonging to the genus Plasmodium. Malaria remains one of the most devastating infectious diseases, killing nearly half a million people each year (WHO 2015). 1,2 With the current increase in drug and insecticide resistance, there is an urgent …

Battle of the Viruses: Aripo Virus Induced Superinfection Exclusion of Mosquito-borne Viruses
… vectors, the most common vector being the mosquito. Currently, many mosquito control strategies are in use, these control strategies are diverse in both efficiency and cost. However, developing new vector control strategies is becoming increasingly important, due to climate changing …

Freirean Codes: A Transformative Educational Tool for Community Empowerment and Arboviral Control in Kenya
… fever are two of the fastest spreading tropical diseases globally. There are 390 million dengue infections per year globally, and 65 million cases in Africa. In East Africa, Kenya and Tanzania have suffered outbreaks of these diseases. Dengue fever is transmitted by the bite of the highly …

MMV008138 and analogs: potential novel antimalarial agents for P. falciparum
Malaria is a severe and deadly mosquito-borne disease. Although treatable, the continuous emergence of multi-drug resistant parasite strains urgently calls for the development of novel antimalarial agents. P. falciparum parasites synthesize essential isoprenoid precursors, isopentenyl pyrophosphate …

Genome engineering and functional gene regulation tools for the study of malaria parasites
… of the most severe form of human malaria, a mosquito-borne disease that remains a major global health problem. The efforts to create new antimalarial drugs and effective vaccines have been significantly hindered by the lack of robust tools for performing functional genetics in P. falciparum. …

Mechanisms and Genetic Determinants of Alphavirus Infection of Mosquito Vectors
Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne disease that has caused hundreds-of-thousands of human and equine cases. Since epizootic strains have historically been the largest public health threat, the majority of experimental studies have focused on these strains. Recently, …

A GIS Analysis of the Environmental Variables Related to Rift Valley Fever Outbreaks
<p>Rift Valley fever is a mosquito-borne disease that causes widespread febrile illness and mortality in domestic animals as well as humans (Gaff, 2007). Rift Valley fever virus was first isolated in 1931 (Daubney, 1931), and since then, outbreaks have occurred in sub-Saharan Africa, southern …

Immunoepidemiological Modeling of Dengue Viral Infection
Dengue viral infection is a mosquito-borne disease with four distinct strains, where the interactions between these strains have implications on the severity of the disease outcomes. The two competing hypotheses for the increased severity during secondary infections are antibody dependent …

Dynamics of La Crosse virus: Surveillance, Control and Effect on Vector Behavior
… is the most common and important endemic mosquito-borne disease of children in the U.S. with an estimated 300,000 annual infections. The disease is maintained in a zoonotic cycle involving the eastern treehole mosquito, Aedes triseriatus and small woodland mammals such as chipmunks and …

Reverse genetics system and fucntion of NSM protein of Rift Valley fever virus (family Bunyaviridae, genus phlebovirus)
… a tripartite negative-strand genome, causes a mosquito-borne disease that is endemic in sub-Saharan African countries and results in large epidemics among humans and livestock. Furthermore, it has potential as a bioterrorist agent and poses a risk for introduction to other areas. In spite of …

La Crosse Virus in Southwestern Virginia: Role of Exotic Mosquito Species and Effect of Virus Infection on Feeding
… family Bunyaviridae is the largest of vertebrate diseases and includes the mosquito-borne disease La Crosse (LAC) virus. Vectors include the major vector Aedes triseriatus and two accessory vectors Aedes albopictus and Aedes japonicus. In the past several decades there has been an increase in the …

Reproductive Success is Secured by a Rapidly-Evolving Short Peptide in Female Aedes Aegypti Mosquitoes
<p>The mosquito lineage spans hundreds of millions of years of evolution, and this period has honed the yellow fever mosquito, Aedes aegypti, into a precise and expert predator. While nectar and plant-derived carbohydrates are sufficient sources of nutrition to maintain energy and metabolism, …

Ecology and Management of Riceland Mosquitoes in Africa With Special Reference to Culex Quinquefasciatus
The diverse mosquito species occurring in African rice agro-ecosystems have been scarcely studied despite the strong link between irrigated rice cultivation and mosquito-borne disease. Studies were conducted to determine the ecology of rice-land mosquitoes in Mwea rice agro-ecosystem, Kenya. In the …
