Characterisation of vector populations

In order to interpret results from experimental hut studies (and linked clinical studies) it is critical to fully characterise the local vector population.  ESSENTIALs is:

  • Determining the Anopheles species composition in the study sites
  • Measuring prevalence and intensity of resistance to pyrethroid insecticides and characterising underpinning mechanisms
  • Monitoring for presence of resistance to additional insecticides incorporated into the ITNs (i.e chlorfenapyr and pyriproxyfen)
  • Determining the level of indoor and outdoor biting and peak biting times
  • Estimating age of the vector population by measuring parity rates
  • Measuring sporozoite infection rates
