Several mutations in voltage gated sodium channel (NAv) have been identified in Aedes aegypti populations worldwide. The variations in the V1016I and F1534C are the most related to knockdown resistance to pyrethroids. A study was carried out to determine the frequency of V1016I and F1534C NAv by rea...

Arboviruses transmitted by Aedes mosquitoes becomes a serious public health problem in numerous regions with increasing worldwide cases of dengue, zika and chikungunya infections. The absence of effective vaccines leads the prevention of these diseases to be focused on vector control activities. The...

The development of an efficient and timely surveillance with accurate alert signals is among the bottlenecks of arboviruses epidemiology. Herein, we report the steps taken to transform an archaic and sectorized structure into a modern and timely surveillance program under the One Health approach to ...

Dengue control in India relies heavily on chemical vector control. Treatment of breeding sites for immature mosquito stages is a common practice. Desert coolers appear to be one of the preferred breeding sites for Aedes mosquitoes. Insect Growth Regulators like pyriproxyfen have been studied as an e...

In this study we aim to determine the lethal and residual effect of a dual-action insecticide coating (INESFLY SATIS) applied in the interior parts of water tanks on Aedes aegypti under laboratory and semi-field conditions.

Dengue virus is transmitted by female mosquito Aedes aegypti and it consists of the most common flavivirus infection. Pakistan is also at high risk of dengue epidemics. The present study focused on the redescription of Aedes aegypti and the detection of dengue virus from 685 field collected larvae o...

Dengue virus has been classified as a worldwide emerging disease. South Texas is potentially at risk for dengue virus introduction due to proximity to Mexico, a country with endemic dengue transmission. Previous research has identified two dengue vectors, Aedes aegypti and Aedes albopictus in the re...

There are several regions in Poland where mosquitoes emerge in huge numbers almost every year. Some of them are areas of protected nature - mainly wetlands, where the insects cannot be controlled in mass actions. Many inhabitants or tourists visiting these regions try to cope with the problem on the...

Due to the scarcity of information about the fauna of mosquitoes in the city of São Paulo, Brazil, an investigation was done with the aim of describing the diversity of species present in green areas of municipal parks in the city. Between March 2011 and February 2012, adult and immature mosquitoes ...

Aedes aegypti and Aedes albopictus are key vectors of dengue and chikungunya.

Here, we present and discuss results obtained from a pilot program using a new approach, the Monitoring System and...

Hospitals play an important role within a healthcare setting. The presence of arthropods in hospitals, like spiders, mites, bedbugs, mosquitoes, beetles, cockroaches, flies and ants, was reported in many studies. Besides its great epidemiological relevance, the presence of culicines that are potenti...

Dengue has been considered as the most important airborne disease in Brazil. Limitations in the laboratory identification of immature Aedes aegypti and processing of field data based on larval surveys led to the development of the “Intelligent Dengue Monitoring” technology (MI-Dengue) (www.midengue....

Man is the main victim of Aedes aegypti. Due to this ecological niche it is one of the most important disease vector to mankind, being, in Brazil, the primary vector of dengue fever. It is found in hot and humid habitat, its development lasts little more than a week, from egg to adult. The only deng...

Mogi Guaçu is a city in southeastern Brazil with 140,000 inhabitants, where the epidemics of dengue are very recent. In 2001 there were only 14 cases, but the incidence increased in the recent years, reaching 566 cases in 2008 and only 21 cases in 2009 (atypical year). The Brateau index for the city...

The present study tests the hypothesis that Ae. aegypti and Ae. albopictus respond differently to urban green areas and houses nearby in the towns of Ouro Preto, at 1100 metres and of Mariana, lower, at 700 metres above sea level. We investigate the prediction that Aedes populations may have been gr...

Dengue and dengue hemorrhagic fever represent one of the greatest challenges to public health at a world level. One of the approaches to mosquito control is the use of chemicals to kill the different stages of the mosquito life cycle. In São Paulo, the chemical control of Aedes aegypti is carried ou...

To combat vectors and the public health hazards they represent, many European countries have established their own vector control programs. Such programs may benefit from a more standardized approach to enable to compare obtained results, share compatible data and tackle transboundary issues. The VB...

Dengue is transmitted to humans by day-biting mosquitoes, primarily Aedes aegypti and Aedes albopictus. Primary prevention of this debilitating disease is through vector (mosquito) control: spraying for adult mosquitoes and applying larvicides to standing water. This presentation provides an overvie...

Aedes (Stegomyia) female mosquitoes feed on sap of herbaceous indoor plants and blood of small mammals. This study investigates whether the female Ae. aegypti and Ae. albopictus provided with sugar solution and mouse blood are still attracted to human after feeding. Laboratory caged females of Aedes...

In this study the efficacy of three Reckitt Benckiser Aerogard® formulations containing IR3535 were assessed. The formulations were: (1) Aerosol (20%...

The basic principles of olfaction in mosquito-host interaction is presented using Aedes aegypti. Olfactometer bioassays investigated which compounds of the complex blend of human emanations play a role in the attraction, and which factors make some hosts more attractive than others. Beside L-(+)-lac...

The Asian tiger mosquito, Aedes albopictus (Sukuse) has a potential to transmit some tropical diseases. Established colonies of Ae. albopictus in Guatemala were first discovered in the Caribbean harbor towns of Puerto Barrios and Puerto de Santo Tomas de Castilla, Department of Izabal in 1995. We in...

We recognise that insecticides must continue to play a major role in most control programmes against insect pests or vectors, particularly when there are emergencies which cannot wait for alternative means of control to be developed. We believe genetic methods should be given serious thought and inv...
