“…14,15,[29][30][31][32][33][34] In the Americas, the co-occurrence of V1016I and F1534C has been found in the Caribbean Islands, Mexico, Brazil, Venezuela and the USA; in Africa, the co-occurrence of V1016I and F1534C in Ghana has been reported. 31,[35][36][37][38][39][40][41] In conclusion, we report here the co-occurrence of mutations V1016I and F1534C in populations of A. aegypti of the Colombian Caribbean region with variation in its allelic and genotypic frequencies. Although F1534C occurs more frequently in the populations studied compared to V1016I, the latter was correlated to resistance to pyrethroids in populations of A. aegypti of the Colombian Caribbean region.…”

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

“…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.

“…Of note, efforts to reduce costs by decreasing the number of traps deployed per house appear to result in decreased efficacy. A recent study in Clovis, CA, by Cornel et al [59] using a single AGO trap per house (144 houses in total) failed to significantly reduce adult Ae. aegypti populations compared to the reductions experienced in the three traps/house interventions performed in Puerto Rico.…”

The intensifying expansion of arboviruses highlights the need for effective invasive Aedes control. While mass-trapping interventions have long been discredited as inefficient compared to insecticide applications, increasing levels of insecticide resistance, and the development of simple affordable traps that target and kill gravid female mosquitoes, show great promise. We summarize the methodologies and outcomes of recent lethal oviposition trap-based mass interventions for suppression of urban Aedes and their associated diseases. The evidence supports the recommendation of mass deployments of oviposition traps to suppress populations of invasive Aedes, although better measures of the effects on disease control are needed. Strategies associated with successful mass-trap deployments include: (1) high coverage (>80%) of the residential areas; (2) pre-intervention and/or parallel source reduction campaigns; (3) direct involvement of community members for economic long-term sustainability; and (4) use of new-generation larger traps (Autocidal Gravid Ovitrap, AGO; Gravid Aedes Trap, GAT) to outcompete remaining water-holding containers. While to the best of our knowledge all published studies so far have been on Ae. aegypti in resource-poor or tropical settings, we propose that mass deployment of lethal oviposition traps can be used for focused cost-effective control of temperate Ae. albopictus pre-empting arboviral epidemics and increasing participation of residents in urban mosquito control.
