Diel Activity of Some Trinidadian Mosquitoes as Related to Transmission of Arboviruses

Abstract

Ecological studies on arthropod-borne diseases (i.e. diseases transmitted by insects, ticks and mites) must of necessity involve a study of the behaviour of the vectors. It is of prime importance to know if the vectors obtain their blood meal during the day, in which case they are called diurnal, or during the night (nocturnal, or indeed if they bite only at dusk or dawn (crepuscular).
