Evolution of kdr haplotypes in worldwide populations of Aedes aegypti: Independent origins of the F1534C kdr mutation. [PDF]

PLoS Neglected Tropical Diseases, 2020
Aedes aegypti is the primary vector of dengue, chikungunya, Zika, and urban yellow fever. Insecticides are often the most effective tools to rapidly decrease the density of vector populations, especially during arbovirus disease outbreaks.

First report of the Phe1534Cys kdr mutation in natural populations of Aedes albopictus from Brazil [PDF]

Parasites & Vectors, 2017
Background Knockdown resistance (kdr), caused by alterations in the voltage-gated sodium channel (NaV), is one of the mechanisms responsible for pyrethroid (PY) resistance.

First report of F1534C kdr mutation in deltamethrin resistant Aedes albopictus from northern part of West Bengal, India [PDF]

Scientific Reports, 2022
Dengue is the most rapidly spreading vector-borne disease with an estimated 100–400 million cases each year. Control of Dengue vectors largely depends upon synthetic pyrethroids.

A new knockdown resistance (kdr) mutation, F1534L, in the voltage-gated sodium channel of Aedes aegypti, co-occurring with F1534C, S989P and V1016G [PDF]

Parasites & Vectors, 2020
Background Aedes aegypti is a primary vector of dengue, chikungunya and Zika infections in India. In the absence of specific drugs or safe and effective vaccines for these infections, their control relies mainly on vector control measures.

The L1014F Kdr mutation is associated with a higher prevalence and load of the Plasmodium-blocking symbiont Microsporidia MB In Anopheles Gambiae s.l. In Benin [PDF]

BMC Microbiology
Introduction The Plasmodium transmission-blocking endosymbiont Microsporidia MB was previously identified in Anopheles gambiae s.l., but its association with the carriage of the genotypes of the L1014F kdr mutation, as well as the ecological factors ...

Tracking pyrethroid resistance in arbovirus mosquito vectors: mutations I1532T and F1534C in Aedes albopictus across Europe [PDF]

Parasites & Vectors
Background With the worldwide spread of the Asian tiger mosquito, Aedes albopictus, the number of autochthonous cases of exotic arboviral diseases, such as dengue or chikungunya, is increasing in temperate regions.

Seasonal variation in species composition, deltamethrin susceptibility, and kdr mutations in anopheles mosquitoes in Northwest Ethiopia. [PDF]

PLoS ONE
BackgroundAnopheles mosquitoes are the main vectors of malaria. Effective vector control depends on understanding their species composition, behavior, distribution, and insecticide resistance.

Knockdown resistance (kdr) mutations in the Japanese encephalitis virus vector Culex tritaeniorhynchus from the Republic of Korea [PDF]

Tropical Medicine and Health
Background Culex tritaeniorhynchus is the primary vector of Japanese encephalitis virus (JEV), a disease of global public health significance, and is widely distributed across Africa, Asia, Australia, and Europe. Despite its epidemiological importance as

Genetic markers associated with insecticide resistance and resting behaviour in Anopheles gambiae mosquitoes in selected sites in Kenya

Malaria Journal, 2021
Background Molecular diagnostic tools have been incorporated in insecticide resistance monitoring programmes to identify underlying genetic basis of resistance and develop early warning systems of vector control failure.

Sub-lethal insecticide exposure affects host biting efficiency of Kdr-resistant Anopheles gambiae

Peer Community Journal, 2021
The massive use of insecticide-treated nets (ITNs) has drastically changed the environment for malaria vector mosquitoes, challenging their host-seeking behaviour and biting success.
