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.

The spread of the Leu&8208;Phe kdr mutation through Anopheles gambiae complex in Burkina Faso : genetic introgression and de novo phenomena

, 2004
During extensive sampling in Burkina Faso and other African countries, the Leu‐Phe mutation producing the kdr pyrethroid resistance phenotype was reported in both Anopheles gambiae ss and A. arabiensis.

The L1014F Knockdown Resistance Mutation Is Not a Strong Correlate of Phenotypic Resistance to Pyrethroids in Florida Populations of Culex quinquefasciatus

Insects
Culex quinquefasciatus is an important target for vector control because of its ability to transmit pathogens that cause disease. Most populations are resistant to pyrethroids and often to organophosphates, the two most common classes of active ...

A sodium channel point mutation is associated with resistance to DDT and pyrethroid insecticides in the peach-potato aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae)

, 1999
The voltage-gated sodium channel is the primary target site of DDT and pyrethroid insecticides, and point mutations in the domain II region of the channel protein have been implicated in the knockdown resistant (kdr) phenotype of several insect species ...
