A one- year study of the biting and resting habits of the malaria vector Anopheles albimanus was
carried out in four rural villages of northern Haiti. Man-biting rates and nighdy biting cycles were determined
by the use of all-night man-biting captures inside and outside houses. Seasonal changes in density and behavior
were determined by repeating the captures on a bimonthly basis throughout one year. Exophily was demon-
strated in these anopheline populations by a comparison of inside-biting with inside-resting densities. These
behavior characteristics are discussed in relation to malaria transmission and to the choice of malaria control
methods.
