Efficacy of Esbiothrin mosquito coils at community level in northern Tanzania

Abstract
Field trials with mosquito coils containing 0.15% Esbiothrin at Usa River settlement, northern Tanzania, during 1986 achieved a 52% reduction in biting rates of Anopheles arabiensis Patton and a 73% reduction of Culex quinquefusciatus Say mosquitoes. No mosquito biting activity occurred during the coil burning period which started at 20.00 hours daily and lasted for an average of 8.6 h. A sociological survey indicated that the coils were favourably accepted and produced no serious side-effects.
