Mosquitoes vector dangerous human diseases during blood feeding. Gustatory (taste) receptor neurons in the mosquito provide important chemical information including the nature and suitability of a potential host. Here we discuss the behavior, neurophysiology and molecular mechanisms associated with feeding in aedine mosquitoes, important vectors of emerging diseases including Zika fever, chikungunya and dengue fever. We describe how interactions between feeding stimulation and deterrency at the peripheral neural receptor level provide input to higher order neural processing centers affecting decisions to feed. A better understanding of gustatory mechanisms involved in the female's decision to bite will provide the framework for novel strategies aimed at preventing the spread of vector-borne disease.
