1. Estirpe de Bacillus thuringiensis da restinga, tóxico ao Aedes (Stegomyia) aegypti (Linnaeus) (Diptera, Culicidae)
Resumo Bacillus thuringiensis é o entomopatógeno mais utilizado no controle do Aedes aegypti, vetor de diferentes agentes etiológicos que causam infecções graves em humanos. Diversos estudos têm como objetivo isolar cepas dessa bactéria de diferentes ambientes, com a perspectiva de selecionar isolados com atividade larvicida para mosquitos. Visando a

2. Evaluation of the insecticidal activity of essential oils and their mixtures against Aedes aegypti (Diptera: Culicidae)
Abstract The search for new insecticides to control dengue fever, chikungunya, and Zika vectors has gained relevance in the past decades. The aim of the present study was to evaluate the larvicidal action of essential oils (EOs) from Thymus vulgaris, Salvia officinalis, Lippia origanoides, Eucalyptus globulus, Cymbopogon nardus, Cymbopogon martinii, Lippia a

3. Genetic differentiation in populations of Aedes aegypti (Diptera, Culicidae) dengue vector from the Brazilian state of Maranhão
ABSTRACT Aedes (Stegomyia) aegypti is the vector responsible for the transmission of the viruses that cause zika, yellow and chikungunya fevers, the four dengue fever serotypes (DENV - 1, 2, 3, 4), and hemorrhagic dengue fever in tropical and subtropical regions around the world. The present study investigated the genetic differentiation of the 15 population

4. Zika virus in Brazil and the danger of infestation by Aedes (Stegomyia) mosquitoes
Abstract Zika virus, already widely distributed in Africa and Asia, was recently reported in two Northeastern Brazilian: State of Bahia and State of Rio Grande do Norte, and one Southeastern: State of São Paulo. This finding adds a potentially noxious virus to a list of several other viruses that are widely transmitted by Aedes (Stegomyia) aegypti and Aedes

5. Insecticide resistance and genetic variability in natural populations of Aedes (Stegomyia) aegypti (Diptera: Culicidae) from Colombia
Mosquito control prevails as the most efficient method to protect humans from the dengue virus, despite recent efforts to find a vaccine for this disease. We evaluated insecticide resistance and genetic variability in natural populations of Aedes aegypti (Linnaeus, 1762) from Colombia. This is the first Colombian study examining kdr mutations and population

6. Flutuação populacional e comparação de métodos de coleta de Aedes (Stegomyia) aegypti (Diptera, Culicidae)
Fatores ambientais podem atuar como reguladores da expansão das populações de Aedes aegypti (Linnaeus, 1762). Este trabalho objetivou avaliar a influência da temperatura, umidade relativa do ar, e precipitação pluviométrica na flutuação populacional de Ae. aegypti. A pesquisa foi conduzida em Boqueirão, Campina Grande e Remígio, Estado da Paraíba

7. A comparison of larval, ovitrap and MosquiTRAP surveillance for Aedes (Stegomyia) aegypti
In Brazil, the entomological surveillance of Aedes (Stegomyia) aegypti is performed by government-mandated larval surveys. In this study, the sensitivities of an adult sticky trap and traditional surveillance methodologies were compared. The study was performed over a 12-week period in a residential neighbourhood of the municipality of Pedro Leopoldo, state

8. Aedes (Stegomyia) aegypti (Diptera: Culicidae) em algumas ilhas de Cabo Verde: tipologia dos criadouros e sua relação com a presença larval
Aedes aegypti é uma espécie de ampla distribuição geográfica, e sua presença foi registrada nas ilhas de Cabo Verde. Pelo fato de a sua bioecologia estar sendo atualmente estudada em várias partes do mundo, e também por ter sido realizado o primeiro registro de uma epidemia de dengue no país, decidiu-se pela realização deste levantamento. O trabal

9. Spatial distribution and esterase activity in populations of Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) resistant to temephos
INTRODUCTION:The need for studies that describe the resistance patterns in populations of Aedes aegypti (Linnaeus) in function of their region of origin justified this research, which aimed to characterize the resistance to temephos and to obtain information on esterase activity in populations of Aedes aegypticollected in municipalities of the State of Para�

10. Genetic profile and molecular resistance of Aedes (Stegomyia) aegypti (Diptera: Culicidae) in Foz do Iguaçu (Brazil), at the border with Argentina and Paraguay
The genetic variability of populations of Aedes (Stegomyia) aegypti (Linnaeus, 1762) is often low due to the intense selection pressure caused by chemical control measures. In this study, we evaluated the susceptibility of larvae and adults of this mosquito to chemical insecticides, the frequency of the Val1016IIe mutation, and the genetic variability of the

11. Field optimisation of MosquiTRAP sampling for monitoring Aedes aegypti Linnaeus (Diptera: Culicidae)
A sticky trap designed to capture gravid Aedes (Stegomyia) aegypti mosquitoes, MosquiTRAP, has been evaluated for monitoring this species in Brazil. However, the effects of trap densities on the capture rate of Ae. aegypti females and the sensitivity of vector detection are still unknown. After a preliminary study has identified areas of high and low female

12. The first report of Aedes (Stegomyia) albopictus in Haiti
Aedes albopictus was found in six of the 10 departments of Haiti and in 14 of the 35 communes surveyed. The survey found the larvae of Ae. albopictus in 13 different types of containers. Used tires and tins were by far the most common breeding sites used by this mosquito species. At the breeding sites, Ae. albopictus was associated with other mosquito specie
