Transcriptional regulation of mosquito oogenesis
<p>The Eastern treehole mosquito, <i>Aedes triseriatus</i> (Say), is the primary vector of La Crosse virus (LACV) in the United States. LACV is maintained in natural populations in part by transovarial transmission from infected females to their progeny. Our understanding of the innate immune …

Mosquito Transposable Elements and piwi Genes
… needed. One possible strategy involves replacing mosquito populations with disease-resistant transgenic mosquitoes. Transposable elements (TEs) are an important component in this new strategy due to their ability to integrate exogenous DNA into chromosomes. They could potentially be useful tools …

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 …

Do Mosquito Pesticides Harm Their Natural Enemies? Ecological Impacts and Non-Target Effects of Larvicides on Mosquito Predators
<p>Larvicides are chemicals used to kill juvenile mosquitoes. When applied to an area, other aquatic organisms are exposed to these chemicals. The removal or impairment of top insect predators could be beneficial to mosquito populations once harmful pesticide levels dissipate. Two common larvicides …

Aquatic Community Interaction Diversity and Mosquito Larvae
Mosquitoes comprise a diverse group of small flies (Diptera) in the familyCulicidae which includes an estimated 3,600 described species. Colloquially we knowmosquitoes as biting insects that pose a threat to humans and domestic animals asimportant vectors of disease. Although a minority of the …

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 …

The Behaviour and Ecology of Mosquito Vectors
Mosquitoes continue to vector pathogens to humans around the world. Research into the unique behaviour and ecology of vector species enables new avenues of control to be developed. I examined two mosquito vector species. The first, Coquillettidia perturbans (Walker, 1856), has been incriminated as …

Exploiting Sugar Feeding Behaviors For Mosquito Control
Mosquitoes are the deadliest animal on the planet killing about a million people a year. These insects are competent vectors of multiple pathogens (e.g., Plasmodium sp, filarial worms, and arboviruses). In most species, females are blood feeders, and must consume a blood meal to complete a …

The early zygotic genes and microRNAs in the yellow fever mosquito Aedes aegypti and the Asian malaria mosquito Anopheles stephensi
Mosquitoes are notorious vectors for multiple diseases like malaria, yellow fever and dengue fever. To manipulate gene expression in mosquito and spread desired genes among natural population for vector control, a thorough understanding of mosquito development and gene regulation is critical. Early …

Zika Modulates Arthropod Histone Methylation in Mosquito Cells
… analysis revealed increased amounts of the mosquito SAMe synthase at both RNA and protein levels, respectively, in ZIKV-infected C6/36 cells at day 1 post infection (p.i.) in comparison to uninfected controls. Increase in the intracellular SAMe levels was noted in ZIKV-infected C6/36 cells …

Discrete and continuous mathematical investigation of juvenile mosquito dynamics
There are thousands of species of mosquitoes, but only a handful of these species carry pathogens that cause human diseases. Here, we study two species, Aedes albopictus and Aedes aegypti, which transmit infections such as dengue, Zika, Mayaro virus, and La Crosse virus. Curtailing these diseases …

Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
… matrices. Thus, coupling biological sampling for mosquito vectors of disease with certain environmental conditions within different landscape configurations may help approximate a model for predicting the risk of encountering these disease vectors. Therefore, the goals of the research were to 1) …

Mosquito odor receptor gene targets to alter vector host choice
Olfaction plays an important role in mosquito behaviors, including foraging for nectar and identifying potential hosts for a blood meal. Mosquitoes detect semiochemicals through odorant receptors, each of which interact with specific odorants. Differences in feeding behaviors have significant …

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, …

Material, acoustic, and mechanical properties of mosquito and midge antennae
… of prior knowledge of the material properties of mosquito or midge antennae, to assess the material structure and to gauge which impact this distribution can have on the antenna's mechanical behaviour in response to sound. It was revealed that, rather than a simple beam of uniform cuticle, the …

Non-Canonical Odor Coding Ensures Robust Mosquito Attraction to Humans
<p>Aedes aegypti mosquitoes spread deadly diseases, including dengue, Zika, yellow fever, and chikungunya. Only female mosquitoes bite, and they do so because they require a blood-meal for reproduction. Aedes aegypti prefer to bite human hosts, which contributes to their effectiveness as a deadly …

Investigations into the oviposition behaviour of the mosquito Anopheles gambiae
… holistic approach than previously used to study mosquito oviposition; oviposition is clearly not a single behaviour, but a complex chain of sensory inputs and responses by the gravid insect.

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 …
