Phlebotomus argentipes (Annandale and Brunetti) (Diptera: Psychodidae) is the phlebotomine sandfly vector responsible for the transmission of Leishmania donovani (Kinetoplastida: Trypanosomatidae), a parasite capable of transmitting the communicable disease, visceral leishmaniasis (VL) or kala-azar, in the Indian sub-continent. This paper presents the preliminary study on the laboratory-based behavioral responses of P. argentipes females to blood-feeding host and P. argentipes males or male extracts, for mating aggregation and blood feeding.
