Effect of Indoor Residual Spraying on Anopheles vector behaviours and their impact on malaria transmission in the northern region of Ghana

Objectives

The objectives of this project are:

1. To determine the extent to which Anopheles mosquito vectors feed and rest outdoors versus indoors in IRS vs. non-IRS areas. Past and current efforts have concentrated on indoor collections using only HLC and PSC methods. This study will use entry/exit trap and resting collection data to sample a mosquito population that has not been adequately sampled to date.
2. To determine if insecticide resistance is important for vector survival or avoidance of vector control interventions.
3. To determine if resistance status for the indoor/outdoor biting and resting populations are factors affecting mosquito infection status.
4. To determine the extent to which human outdoor activities overlap with mosquito biting activities that may impact malaria transmission risk.
