Controlling Aedes Aegypti and Aedes Albopictus: Information for Vector Control Programs

Centers for Disease Control and Prevention. 03/31/2016This two-page fact sheet provides information about vectors of chikungunya, dengue, and Zika viruses, and recommends using integrated vector management (IVM) strategies for Aedes aegypti and Aedes albopictus species mosquitoes, the primary vectors. It describes recommended ways to control mosquitoes, which include conducting surveillance, removing larval habitats, controlling adult mosquitoes, and monitoring for pesticide resistance. (PDF)

AbstractSouth Texas has experienced local transmission of Zika virus and of other mosquito-borne viruses such as chikungunya virus and dengue virus in the last decades. Using a mosquito surveillance program in the Lower Rio Grande Valley (LRGV) and San Antonio, TX, from 2016 to 2018, we detected the presence of an insect-specific virus, cell fusing agent virus (CFAV), in theAedes aegypti mosquito population. We tested 6,326 females and 1,249 males from the LRGV and 659 females from San Antonio for CFAV by RT-PCR using specific primers. Infection rates varied from 0 to 261 per 1,000 mosquitoes in the LRGV and 115 to 208 per...

The disease is transmitted through the bite of the female Aedes aegypti mosquito, an invasive species that also spreads diseases like yellow fever, Zika and chikungunya.

In this study, we investigate the genetic variation associated with blocking and use these analyses to generate testable hypotheses surrounding the mechanism of Wolbachia-mediated dengue blocking. From our results, we hypothesize that Wolbachia may block virus replication by increasing the regeneration rate of mosquito cells via the Notch signaling pathway. We also propose that Wolbachia modulates the host’s transcriptional pausing pathway either to prime the host’s anti-viral response or to directly inhibit viral replication.

We performed an in-depth analysis of the ABC gene family in Aedes aegypti (Diptera: Culicidae), which is an important vector species of arthropod-borne viral infections such as chikungunya, dengue, and Zika. Desp...

After the outbreak in French Polynesia, Zika virus (ZIKV) explosive pandemic occurred in 2015, reports that ZIKV was linked to other diseases, especially neurological complications such as Guillain-Barré Syndrome (GBS), also burst in almost every continent, thereby turning into an international concern. In South America, the highest incidence occurred in Venezuela with approximately 680 cases of GBS after ZIKV infection. Currently, the main roots of this association remain unknown. In this regard, it is thought that the immune system plays a central role in such association through the host protection or even improv...

gari Alphaviruses are globally distributed and predominately transmitted by mosquitoes. Aedes species are common vectors for the clinically important alphaviruses—Chikungunya, Sindbis, and Ross River (RRV) viruses—with Aedes aegypti also being a vector for the flaviviruses dengue, Yellow Fever, and Zika viruses. Ae. aegypti was putatively implicated in the large 1979–1980 South Pacific Islands outbreak of RRV—the leading cause of arboviral disease in Australia today. The RNA interference (RNAi) defense response in mosquitoes involves a number of small RNAs, with their kinetics in...

This study consists of the application of a community prevention project. Different surveys and methodological approaches were used. Associations between socio-environmental determinants and knowledge and practices for arboviruses transmission control were estimated by odds ratio. Logistic regression and qualitative techniques were used. Although around 75% of households had an adequate knowledge about arboviruses' origin and transmission, only 30% of them adopted adequate practices. Domestic risk practices were associated with serious deficiencies in water and sanitation services. Furthermore, a perception of greater risk...

Chikungunya virus (CHIKV) is an arthropod-borne virus (arbovirus) of epidemic concern, transmitted by Aedes ssp. mosquitoes, and is the etiologic agent of a febrile and incapacitating arthritogenic illness responsible for millions of human cases worldwide. After major outbreaks starting in 2004, CHIKV spread to subtropical areas and western hemisphere coming from sub-Saharan Africa, South East Asia, and the Indian subcontinent. Even though CHIKV disease is self-limiting and non-lethal, more than 30% of the infected individuals will develop chronic disease with persistent severe joint pain, tenosynovitis, and incapacitating...

Abstract Neglected tropical diseases are a serious global public health problem and they are one of the main causes of mortality and morbidity, especially in underdeveloped countries. These diseases have several implications for health and they are considered a priority in global eradication programs for disease control. The aim of this mini-review is to report recent studies on the fight against neglected diseases, namely dengue fever, chikungunya, zika, malaria protozoa, Chagas disease, leishmaniasis, schistosomiasis helminths, filariasis, and tuberculosis bacteria using extracts and isolated substances of endop...
