Knockdown resistance mutations in Phlebotomus argentipes sand flies in Bihar, India. [PDF]

Parasit Vectors
Abstract Background Vector control based on indoor residual spraying (IRS) is one of the main components of the visceral leishmaniasis (VL) elimination programme in India. Dichlorodiphenyltrichloroethane (DDT) was used for IRS until 2015 and was later replaced by the synthetic pyrethroid alpha-cypermethrin.

Insecticide resistance status in Anopheles gambiae in southern Benin. [PDF]

, 2010
BACKGROUND: The emergence of pyrethroid resistance in Anopheles gambiae has become a serious concern to the future success of malaria control. In Benin, the National Malaria Control Programme has recently planned to scaling up long-lasting insecticidal ...

Rescue of the TTF2 Knockdown Phenotype with an siRNA-Resistant Replacement Vector [PDF]

Cell Cycle, 2004
TTF2 is an RNA polymerase II termination factor that is responsible for mitotic repression of transcription elongation. Normally, all RNA polymerase II molecules are eliminated from condensed mitotic chromosomes, but siRNA-mediated knockdown of TTF2 causes a phenotype in which polymerases are retained on mitotic chromosomes.

Socioeconomic predictors of knockdown resistance in the globally invasive tiger mosquito Aedes albopictus [PDF]

Royal Society Open Science
The tiger mosquito Aedes albopictus (Skuse) is a nuisance biter and vector for many dangerous pathogens. Population control of this species primarily relies on the spraying of chemical insecticides.

Association of knockdown resistance mutations with pyrethroid resistance in Aedes aegypti, a major arbovirus vector in Cameroon. [PDF]

Parasit Vectors
Abstract Background The development of insecticide resistance in Aedes mosquitoes has been reported in several African countries. However, information about the mechanisms involved remains scarce. This study aimed to address this issue by updating the resistance profile of A.

Molecular survey of knockdown resistance to pyrethroids in human scabies mites [PDF]

Clinical Microbiology and Infection, 2014
There are growing concerns about the emergence of resistance of Sarcoptes scabiei to permethrin and other pyrethroid derivatives. Sarcoptes scabiei mites collected from 40 patients visiting two hospitals near Paris, France, were genotypically characterized considering two parts of their voltage-sensitive sodium channel gene.
