Levels of Resistance to Pyrethroid among Distinct kdr Alleles in Aedes aegypti Laboratory Lines and Frequency of kdr Alleles in 27 Natural Populations from Rio de Janeiro, Brazil

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
Background. Several mutations in voltage gated sodium channel (NaV) have been identified in Aedes aegypti populations worldwide. However, only few are related to knockdown resistance to pyrethroids, most of which with variations in the 1016 and 1534 NaV sites.

Insecticide Resistance and Fitness: The Case of Four Aedes aegypti Populations from Different Brazilian Regions

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
Background. Chemical control is still a major strategy to constrain vector density and mitigate pathogen transmission. However, insecticide overuse poses a high selective pressure, favouring the spread of resistance alleles in natural populations. In an insecticide‐free environment, a fitness cost is expected in resistant insects when compared to ...

Triflumuron Effects on the Physiology and Reproduction of Rhodnius prolixus Adult Females

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
We evaluated the efficacy of the growth regulator triflumuron (TFM) in inducing mortality and disrupting both oviposition and egg hatching in Rhodnius prolixus adult females. TFM was administered via feeding, topically or by continuous contact with impregnated surfaces.

Distribution and dissemination of the Val1016Ile and Phe1534Cys Kdr mutations in Aedes aegypti Brazilian natural populations

Parasites & Vectors, 2014
Background The chemical control of the mosquito Aedes aegypti, the major vector of dengue, is being seriously threatened due to the development of pyrethroid resistance. Substitutions in the 1016 and 1534 sites of the voltage gated sodium channel (AaNaV),

Efficacy of insecticides used in indoor residual spraying for malaria control: an experimental trial on various surfaces in a “test house”

Malaria Journal, 2019
Background Malaria is a public health problem in the Brazilian Amazon region. In integrated vector management for malaria (anopheline) control, indoor residual spraying (IRS) represents one of the main tools in the basic strategy applied in the Amazonian

Métodos de controle de insetos vetores: um estudo das classificações

Revista Pan-Amazônica de Saúde, 2013
Com objetivo de observar a estabilidade e a coerencia dos metodos de controle de vetores, realizou-se uma analise das classificacoes desses metodos na literatura. Foram consultadas 22 classificacoes, retiradas de livros-texto, manuais e publicacoes tecnicas, dando-se especial atencao as da Organizacao Mundial da Saude (cinco). O controle quimico esteve

Resistance Status to the Insecticides Temephos, Deltamethrin, and Diflubenzuron in Brazilian Aedes aegypti Populations

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
Insecticides are still largely applied in public health to control disease vectors. In Brazil, organophosphates (OP) and pyrethroids (PY) are used against Aedes aegypti for years. Since 2009 Insect Growth Regulators (IGR) are also employed in the control of larvae. We quantified resistance to temephos (OP), deltamethrin (PY), and diflubenzuron (IGR) of
