Perceptions of measures to control Aedes mosquitoes and mosquito-borne diseases in Costa Rica
Aedes mosquitoes are responsible for the transmission of several arboviruses throughout tropical and subtropical regions of the world. In the Americas, Aedes aegypti is the most competent vector of dengue, chikungunya, Zika, and yellow fever. With up to 400 million cases globally each year, dengue …

The Effect of Precipitation on the Spread of Mosquito-Borne Diseases: A Case Study of Florida Counties
… as the fastest growing in the entire country. A mosquito bite may mean the transmission of a virus or disease which might be fatal. Hence, there is a need for the state to control mosquitoes through the various Departments of Mosquito Control in each of its sixty-seven (67) counties. Six locally …

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 …

Occupational Hazards Among Mosquito Control Operators And Other Pesticide Handlers
The rise of mosquito-borne diseases is a serious public health concern. Mosquito control employees work within municipal/county health departments, public works, private companies, and other agencies. These outdoor workers encounter various occupational health and safety hazards, including exposure …

New tools for the study of virus-vector interactions in mosquitoes
Mosquito-borne diseases continue to be a burden to global health. The viruses that cause these diseases are maintained in nature through a biological transmission cycle involving susceptible vertebrate and mosquito hosts. While knowledge of the interactions occurring between mosquito-borne viruses …

Analysis of the feeding behaviour of the mosquito Culex pipiens L. (Diptera: Culicidae) in relation to West Nile virus
… of West Nile Virus (WNV) transmission by its mosquito vector, Culex pipiens and to elucidate how Cx. pipiens and WNV are intertwined. The first few sections of the literature review describe the life cycle and blood feeding behaviours ofmosquitoes so that baseline data ofmosquito biology are …

Vectors of Health: Epidemics, Ecologies, and the Reinvention of Mosquito Science in Brazil
The Aedes aegypti mosquito can be a disease vector, transmitting pathogenic viruses that are harmful to human health, such as Zika, dengue, chikungunya, and yellow fever. Since the early 20th century, this insect has been the focus of scientific research and public health campaigns, framed as a …

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 …

Mathematical Modeling of Dengue Viral Infection
… has become one of the most widely-spread mosquito-borne diseases in the world, with an estimated 50-100 million cases annually, resulting in 500,000 hospitalizations. Due to the nature of the immune response to each of the four serotypes of dengue virus, secondary infections of dengue put …

Are Post-Transcriptional RNA Modification Events in the Glutamate-Gated and GABA-Gated Chloride Channels of Anopheles minimus and Anopheles dirus associated with Ivermectin Insensitivity?
Mosquito-borne diseases, most notably malaria, have been a constant public health challenge in many regions around the world claiming the lives of hundreds of thousands every year. Vector control strategies such as insecticide use were initially effective in reducing malaria transmission. However, …

Behavioral Ecology and Associated Virology of Mosquito-Host Interactions in Southern California
<p>Elucidating characteristics of mosquito-host interactions are critical for understanding the ecology and epidemiology of mosquito-borne diseases. In this dissertation, I conducted three studies to explore potential mosquito-host interactions and associated virus infection rates. I first …

Modeling Temperature Effects on Vector-Borne Disease Dynamics
Vector-borne diseases (VBDs) cause significant harm to humans, plants, and animals worldwide. For instance, VBDs are very difficult to manage, as they are governed by complex interactions. VBD transmission depends on the pathogen itself, vector-host movement, and environmental conditions. …

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, …

ANTI-MOSQUITO BEHAVIOR OF ADULT AND JUVENILE WHITE-FOOTED MICE (PEROMYSCUS LEUCOPUS) (TREEHOLE MOSQUITO, AEDES TRISERIATUS, EPIDEMIOLOGY)
<p>Rodents seldom are identified as hosts for mosquitoes, based on serological analysis of bloodmeals. However, due to limited survey and lack of sensitivity in most bloodmeal analyses, host species can be misrepresented or undetected. Knowledge of behavior of a potential host species can …

Predicting malaria dynamics under climate change
… pools provide the habitat for the Anopheles mosquitoes, and temperature influences this vector's ability to spread disease. Climate change drives shifts in microtopographic controls on the persistence of mosquito habitat and the life cycles of Anopheles vector and Plasmodium parasite, which …

Modulation of Alphaviruses by Small RNAs
Mosquito-borne diseases remain a significant burden on global public health. Maintenance of mosquito-borne viruses in nature requires a biological transmission cycle that involves alternating virus replication in a susceptible vertebrate and mosquito host. Although infection of the vertebrate host …

Reading Between the Strands: Deciphering Double Stranded RNA-Based Immune Responses in Mosquito-Virus Interactions
Mosquitoes are responsible for transmitting several medically important viruses that cause widespread illness and pose a major public health concern. Among them, Culex quinquefasciatus is a globally distributed vector species that contributes to the spread of multiple arthropod-borne viruses. …

The Genetics Of Mosquito Heat-Seeking Behavior
… adaptation is found in the female Aedes aegypti mosquito, which becomes attracted to the body heat of endothermic ("warmblooded") hosts when in pursuit of a blood meal. Mosquitoes are remarkably adept at finding hosts in their environment and have become major vectors of human disease, but much …

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, …

The Neuropeptide Regulation of Host-Seeking Behavior in Aedes Aegypti Mosquitoes
<p>Aedes aegypti mosquitoes are the principal vectors for several human diseases including Dengue Fever, which causes ~400 million cases and ~24,000 deaths per year (Bhatt et al., 2013; WHO, 2002). Novel strategies to combat mosquito-borne diseases are needed for A. aegypti and other mosquitoes …
