BACKGROUND Knockdown resistance is conferred primarily by non‐synonymous mutations that reduce pyrethroids binding to voltage‐gated sodium channels. In 2014, kdr mutation V1016I in Aedes aegypti populations resistant to pyrethroids was reported for the first time in Colombiα, in 2016 another kdr mutation, F1534C, and in 2018 the mutation V419L. Nine populations of A. aegypti, previously characterized as being resistant to λ‐cyhalothrin, deltamethrin, cyfluthrin and permethrin, were used for this study. Genomic DNA was used to determine genotypes by allele‐specific PCR for mutations V1016I and F1534C, and to determine their association with pyrethroid resistance. RESULTS All the populations analyzed showed both mutations, with allelic frequencies of 0.07–0.35 for I1016 and 0.47–0.88 for C1534. A percentage of co‐occurrence of mutant homozygotes I1016/C1534 of 5.3% was detected. A significant positive correlation was found between the frequency of the genotype I1016 and the resistance to permethrin, λ‐cyhalothrin and cyfluthrin, but not to deltamethrin; on the other hand, the correlation was not significant for the C1534 genotype and the four pyrethroids evaluated. No significant correlation was found between the frequencies of the mutations V1016I and F1534C. CONCLUSIONS Both mutations V1016I and F1534C are present in A. aegypti populations of the Colombian Caribbean, and although the frequency of F1534C exceeds V1016I, the latter was correlated to resistance to pyrethroid insecticides. © 2018 Society of Chemical Industry

The yellow fever mosquito, Aedes aegypti, particularly in Neotropical regions, is the principal vector of dengue, yellow fever, Zika and Chikungunya viruses. Pyrethroids remain one of the most used insecticides to control Aedes mosquitoes, despite the development of pyrethroid resistance in many mosquito populations worldwide. Here, we report a Brazilian strain of A. aegypti with high levels (approximately 100–60,000 fold) of resistance to both type I and type II pyrethroids. We detected two mutations (V410L and F1534C) in the sodium channel from this resistant strain. This study is the first report of the V410L mutation in mosquitoes. Alone or in combination with the F1534C mutation, the V410L mutation drastically reduced the sensitivity of mosquito sodium channels expressed in Xenopus oocytes to both type I and type II pyrethroids. The V410L mutation presents a serious challenge for the control of A. aegypti and will compromise the use of pyrethroids for the control of A. aegypti in Brazil; therefore, early monitoring of the frequency of the V410L mutation will be a key resistance management strategy to preserve the effectiveness of pyrethroid insecticides.

“…However, the V1016G mutation has not been reported in Latin America [31,32,46,47]. Instead, mutation V1016I was found, and often coexists with F1534C in South and North America, such as Venezuela [48], three French overseas territories [49], Brazil [50,51,52], Mexico [53], and the USA [54]. More recently, V1016I and F1534C were detected in Ghana, Africa [55], and a new mutation, T1520I, was found along with the F1534C mutation in a population in India [56].…”

Pyrethroid insecticides are widely used to control insect pests and human disease vectors. Voltage-gated sodium channels are the primary targets of pyrethroid insecticides. Mutations in the sodium channel have been shown to be responsible for pyrethroid resistance, known as knockdown resistance (kdr), in various insects including mosquitoes. In Aedes aegypti mosquitoes, the principal urban vectors of dengue, zika, and yellow fever viruses, multiple single nucleotide polymorphisms in the sodium channel gene have been found in pyrethroid-resistant populations and some of them have been functionally confirmed to be responsible for kdr in an in vitro expression system, Xenopus oocytes. This mini-review aims to provide an update on the identification and functional characterization of pyrethroid resistance-associated sodium channel mutations from Aedes aegypti. The collection of kdr mutations not only helped us develop molecular markers for resistance monitoring, but also provided valuable information for computational molecular modeling of pyrethroid receptor sites on the sodium channel.
