Insecticide resistance in malaria vector mosquitoes at four localities in Ghana, West Africa.

Background: Malaria vector control programmes that rely on insecticide-based interventions such as indoor house spraying with residual insecticides or insecticide treated bed nets, need to base their decision-making process on sound baseline data. More and more commercial entities in Africa, such as mining companies, are realising the value to staff productivity of controlling malaria transmission in their areas of operation.This paper presents baseline entomological data obtained during surveys conducted for four mining operations in Ghana, West Africa.
