First report of the East African kdr mutation in an Anopheles gambiae mosquito in Côte d’Ivoire [version 1; referees: 2 approved]

Wellcome Open Research, 2017
Background. The intensive use of insecticides in public health and agriculture has led to the development of insecticide resistances in malaria vectors across sub-Saharan Africa countries in the last two decades.

PCR-based methods for the detection of L1014 kdr mutation in Anopheles culicifacies sensu lato [PDF]

Malaria Journal, 2009
Background Anopheles culicifacies s.l., a major malaria vector in India, has developed widespread resistance to DDT and is becoming resistant to pyrethroids–the only insecticide class recommended for the impregnation of bed nets.

Multiple origins of the sodium channel kdr mutations in codling moth populations. [PDF]

PLoS ONE, 2012
Resistance to insecticides is one interesting example of a rapid current evolutionary change. DNA variability in the voltage-gated sodium channel gene (trans-membrane segments 5 and 6 in domain II) was investigated in order to estimate resistance ...

Pyrethroid-resistance and presence of two knockdown resistance (kdr) mutations, F1534C and a novel mutation T1520I, in Indian Aedes aegypti.

PLoS Neglected Tropical Diseases, 2015
BackgroundControl of Aedes aegypti, the mosquito vector of dengue, chikungunya and yellow fever, is a challenging task. Pyrethroid insecticides have emerged as a preferred choice for vector control but are threatened by the emergence of resistance.

Knockdown resistance (kdr) mutations in Indian Anopheles culicifacies populations [PDF]

Parasites & Vectors, 2015
Background Anopheles culicifacies s.l. is one of the primary vectors of malaria in India responsible for the highest number of malaria cases. This vector is resistant to DDT in most parts of the country with indication of emerging resistance to ...

Evidence of increasing L1014F kdr mutation frequency in Anopheles gambiae s.l. pyrethroid resistant following a nationwide distribution of LLINs by the Beninese National Malaria Control Programme

Asian Pacific Journal of Tropical Biomedicine, 2014
Objective: To determine the susceptibility status to pyrethroid in Anopheles gambiae s.l. (An. gambiae), the distribution of kdr “Leu-Phe” mutation in malaria vectors in Benin and to compare the current frequency of kdr “Leu-Phe” mutation to the previous

The pattern of kdr mutations correlated with the temperature in field populations of Aedes albopictus in China [PDF]

Parasites & Vectors, 2021
Background Aedes albopictus is the primary vector of dengue fever in China. This mosquito species has a wide distribution range in China and can be found in the tropical climate zones of southern provinces through to temperate climate zones of northern ...

Development of an allele-specific, loop-mediated, isothermal amplification method (AS-LAMP) to detect the L1014F kdr-w mutation in Anopheles gambiae s. l.

Malaria Journal, 2012
Background Malaria control relies heavily on treated bed nets and indoor residual spraying with pyrethroid insecticides. Unfortunately, the resistance to pyrethroid insecticides, mainly due to the kdr mutation, is spreading in the main malaria vector ...

Assessing the effects of Aedes aegypti kdr mutations on pyrethroid resistance and its fitness cost. [PDF]

PLoS ONE, 2013
Pyrethroids are the most used insecticide class worldwide. They target the voltage gated sodium channel (NaV), inducing the knockdown effect. In Aedes aegypti, the main dengue vector, the AaNaV substitutions Val1016Ile and Phe1534Cys are the most ...
