Does kdr genotype predict insecticide resistance phenotype in mosquitoes ?

, 2009
Several groups are developing and applying DNA-based technologies to monitor insecticide-based disease control programmes. However, several recent papers have concluded that the knockdown resistance (kdr) genotype-phenotype correlation that is observed ...

Knockdown-resistance (kdr) mutations in Indian Aedes aegypti populations: Lack of recombination among haplotypes bearing V1016G, F1534C, and F1534L kdr alleles

PLOS Neglected Tropical Diseases
Background Knockdown resistance (kdr) mutations in the voltage-gated sodium channel (VGSC) gene are a key mechanism of insecticide resistance in mosquitoes. In Asian Aedes aegypti populations two main VGSC haplogroups with kdr mutations have been identified: one carrying the F1534C mutation and another with V1016G and/or S989P mutations.

Aedes aegypti on Madeira Island (Portugal): genetic variation of a recently introduced dengue vector

Memorias do Instituto Oswaldo Cruz, 2013
The increasing population of Aedes aegypti mosquitoes on Madeira Island (Portugal) resulted in the first autochthonous dengue outbreak, which occurred in October 2012.

Insecticide resistance status and high frequency of kdr mutations in Aedes aegypti in Tegucigalpa, Honduras

Parasites & Vectors
Abstract Background Aedes aegypti is the main vector of arboviruses in the Americas. Insecticide use remains the primary method for outbreak control, but prolonged application exerts selective pressure that promotes resistance.

Presence of the knockdown resistance mutation, Vgsc-1014F in Anopheles gambiae and An. arabiensis in western Kenya

Parasites & Vectors, 2015
Introduction The voltage gated sodium channel mutation Vgsc-1014S (kdr-east) was first reported in Kenya in 2000 and has since been observed to occur at high frequencies in the local Anopheles gambiae s.s. population.

Assessing pyrethroid resistance in Aedes aegypti from Cordoba Colombia: Implications of kdr mutations

PLOS ONE
Resistance to insecticides is one of the great challenges that vector control programs must face. The constant use of pyrethroid-type insecticides worldwide has caused selection pressure in populations of the Aedes aegypti vector, which has promoted the emergence of resistant populations. The resistance mechanism to pyrethroid insecticides most studied
