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.

Reduced efficacy of insecticide-treated nets and indoor residual spraying for malaria control in pyrethroid resistance area, Benin. [PDF]

, 2007
The pyrethroid knockdown resistance gene (kdr) has become widespread in Anopheles gambiae in West Africa. A trial to test the continuing efficacy of insecticide-treated nets (ITN) and indoor residual spraying (IRS) was undertaken in experimental huts at ...

A pre-intervention study of malaria vector abundance in Rio Muni, Equatorial Guinea: their role in malaria transmission and the incidence of insecticide resistance alleles. [PDF]

, 2008
BACKGROUND: Following the success of the malaria control intervention on the island of Bioko, malaria control by the use of indoor residual spraying (IRS) and long-lasting insecticide-treated nets (LLITN) was extended to Rio Muni, on the mainland part of

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.

Biochemical basis of permethrin resistance in Anopheles arabiensis from Lower Moshi, north-eastern Tanzania. [PDF]

, 2010
BACKGROUND: Development of resistance to different classes of insecticides is a potential threat to malaria control. With the increasing coverage of long-lasting insecticide-treated nets in Tanzania, the continued monitoring of resistance in vector ...

Insecticide susceptibility status and knockdown resistance (kdr) mutation in Aedes albopictus in China. [PDF]

Parasit Vectors, 2021
BackgroundAedes (Stegomyia) albopictus (Skuse, 1894) is the main vector of dengue virus in China. The resistance to insecticides is a huge obstacle for the control of this species, and determining its resistance status and mechanisms in China is ...

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.
