Geometric mean catches of all anophelines, and of those found blood fed, by pyrethrum spraying to collect mosquitoes resting indoors in bedrooms and by window exit traps in/on bedrooms with treated nets in treated lowland hamlets or in rooms without nets in untreated hamlets in January–July 2000. Also included are the light trap catches in rooms with untreated nets over the same months, as a measure of the vector populations of these hamlets, and hence a calculation of the % of the reduction in biting which is attributable to the personal protection due to the treated nets. | ||
