Project description:Resistance to pyrethroids, the only insecticide approved for bednets, threatens control of the major malaria vector, Anopheles funestus, in Malawi. To improve the management of such resistance countrywide, it is crucial to understand the dynamics and mechanisms driving resistance in the field. In this study the levels of insecticide resistance were determined across the highly endemic densely populated lake and southern agricultural area. Insecticide resistance to pyrethoids was assessed using standardized WHO bioassay methods and resistant mosquitoes were hybridized to susceptible mosquitoes. This microarray analysis revealed the key role of cytochrome P450 genes such as CYP6P9a, CYP6P9b and CYP6M7. However, a significant shift in the over-expression of these CYP450s was detected across a south/north transect, with CYP6M7 more highly over-transcribed in the two northern collection sites and the tandemly duplicated genes, CYP6P9a and CYP6P9b, more greatly over-transcribed in the south.

Project description:Identification of genes associated with bendiocarb resistance. Mosquitoes collected as larvae from Nagongera and Kihihi, Uganda. Bendiocarb-resistant and unexposed female mosquitoes selected using standard WHO tube bioassays. RNA was extracted from pools of five individuals identified as An. gambiae s.s. Insecticide-susceptible mosquitoes from the Kisumu strain were included as controls. RNA hybridized in an interwoven loop design to compare four biological replicates each of resistant, unexposed, and laboratory mosquitoes.
