Aedes aegypti prefers densely populated habitats, but has been shown to explore less anthropogenic environments. We investigated composition of the abundance of mosquitoes in forested areas and assessed relationships between species occurrences and different types of land use and land cover at three spatial scales (100m, 500m and 1000m). Mosquitoes were collected from October 2012 to March 2013...

Dengue virus (DENV) is an arbovirus transmitted to humans by the bite of infected Aedes mosquitoes. Experimental per os infection of mosquitoes with DENV is usually a preliminary step in virus/vector studies but it requires being able to prepare artificial blood-meals with high virus titers. We report here the convenient use of centrifugal filter devices to quickly concentrate DENV particles in...

CHRISTENSEN, B. M. 1978. Dirofilaria immitis: Effect on the longevity of Aedes trivittatus. Experimental Parasitology 44, 116-123. Laboratory studies on vector mortality as related to parasite burden revealed that the mosquito Aedes trivittutus showed considerable tolerance to infection with the filarial nematode Dirofilaria immitis. Although mosquitoes exposed to a dog with a high microfilarem...

etiological agent Zika virus is a single-stranded RNA Flavivirus of the Flaviviridae family, transmitted by mosquitoes of the genus Aedes sp. It was identified in Rhesus monkeys in 1947, in the Zika Forest, Uganda, Africa, during jungle yellow fever surveillance. The first report of the disease in humans dates back to 1952 (cited by Campos GS et al.).1 Zika virus (ZIKV) was known until the end ...

© 2017 Indian Dermatology Online Journal | Published by Wolters Kluwer ‐ Medknow Chikungunya (CHK) is an acute onset, mosquito‐borne viral disease characterized by high fever, predominant musculo‐skeletal symptoms, and skin rash. It is a re‐emerging viral infection transmitted to humans by infected mosquitoes. The etiological agent is a RNA virus that belongs to the alphavirus genus of the fami...

This work is devoted to analyzing an impulsive control synthesis maintain the self-sustainability of Wolbachia among Aedes Aegypti mosquitoes. The present paper provides a fractional order invasive model. Through fixed point theory, this derives existence and uniqueness results for proposed Also, we performed global Mittag-Leffler stability analysis via Linear Matrix Inequality theory Lyapunov ...

The Bacillus laterosporus strains 921 and 615 were shown to have toxicity for larvae of the mosquitoes Aedes aegypti, Anopheles stephensi, and Culex pipiens. The larvicidal activity of B. laterosporus was associated with spores and crystalline inclusions. Purified B. laterosporus 615 crystals were highly toxic for Aedes aegypti and Anopheles stephensi.

Endogenous viral elements derived from nonretroviral RNA viruses have been described in various animal genomes. Whether they have a biological function, such as host immune protection against related viruses, is a field of intense study. Here, we investigated the repertoire of endogenous flaviviral elements (EFVEs) in Aedes mosquitoes, the vectors of arboviruses such as dengue and chikungunya v...

Zika virus (ZIKV) is a vector-borne flavivirus that has caused recent outbreaks associated with serious disease in infants and newborns in the Americas. Aedes mosquitoes are the primary vectors for ZIKV, but little is known about the diversity of mosquitoes that can transmit ZIKV in North America. We chose three abundant North American mosquito species (Anopheles freeborni, Anopheles quadrimacu...

The mosquito-borne flaviviruses revealed two distinct epidemiological groups. The neurotropic viruses correlated with the Culex vectors, and the viruses associated with haemorrhagic diseases correlated with the Aedes vectors. About the last ones, it is hypothesized that the dengue viruses have evolved from sylvatic strains that are transmitted among non-human primates in West Africa and Malaysi...
