Insecticide resistance and underlying targets-site and metabolic mechanisms in Aedes aegypti and Aedes albopictus from Lahore, Pakistan

Scientific Reports, 2021
Insecticide resistant Aedes populations have recently been reported in Pakistan, imposing a threat to their control. We aimed to evaluate the susceptibility of Aedes aegypti and Aedes albopictus populations from Lahore to WHO-recommended insecticides and

Genetic structure and kdr mutations in Aedes aegypti populations along a road crossing the Amazon Forest in Amapá State, Brazil

Scientific Reports, 2023
Insecticide resistance in Aedes aegypti poses a significant threat to disease control. One form of resistance, caused by kdr mutations in the Na V gene, hinders vector control efforts in Brazil.

Assessment of the susceptibility status of Aedes aegypti (Diptera: Culicidae) populations to pyriproxyfen and malathion in a nation-wide monitoring of insecticide resistance performed in Brazil from 2017 to 2018

Parasites & Vectors, 2020
Background Chemical mosquito control using malathion has been applied in Brazil since 1985. To obtain chemical control effectiveness, vector susceptibility insecticide monitoring is required.

First national-scale evaluation of temephos resistance in Aedes aegypti in Peru

Parasites & Vectors, 2022
Background The development of resistance against insecticides in Aedes aegypti can lead to operational failures in control programs. Knowledge of the spatial and temporal trends of this resistance is needed to drive effective monitoring campaigns, which ...

Evaluation of resistance to pyrethroid and organophosphate adulticides and kdr genotyping in Aedes aegypti populations from Roraima, the northernmost Brazilian State

Parasites & Vectors, 2020
Background Roraima, the northernmost State in Brazil, borders Venezuela and Guyana. Although mostly covered by the tropical forests, the urban centers of this state are highly infested with Ae. aegypti and are endemic for dengue, Zika and chikungunya. We

Olhar muito além do vetor: uma análise a partir do discurso coletivo sobre uso de plantas no controle de vetores [PDF]

Revista Brasileira de Gestão Ambiental e Sustentabilidade, 2019
Diversos estudos comprovam a baixa efetividade das práticas de controle do vetor via aplicação de inseticidas em centros urbanizados. O uso de plantas no controle do Aedes aegypti tem se mostrado uma alternativa viável há várias décadas, entretanto, o desconhecimento dos indivíduos sobre a sua ação leva a rejeição desta medida.

Insecticide resistance, fitness and susceptibility to Zika infection of an interbred Aedes aegypti population from Rio de Janeiro, Brazil

Parasites & Vectors, 2020
Background Aedes aegypti is a vector of high relevance, since it transmits several arboviruses, including dengue, chikungunya and Zika. Studies on vector biology are usually conducted with laboratory strains presenting a divergent genetic composition ...
