The adult female sand flies started laying eggs 6 days after blood meal and lasted for 8 days. It lives in the vagina of women. A short peptide containing an RGD (Arg-Gly-Asp) sequence flanked by cysteine residues in the C-terminal end was identified as the most abundant transcript in the Lu. Visceral leishmaniasis is transmitted through the bites of phlebotomine sandflies, small dipterans that rarely exceed 3 mm in length (Killick‐Kendrick, 1999), of which Phlebotomus argentipes (Diptera: Psychodidae) is the only incriminated VL vector on the Indian subcontinent (Dinesh et al., 2000).

Visceral leishmaniasis (VL), transmitted by the sand fly, Phlebotomus argentipes, is frequently reported on the Indian subcontinent where its basic ecology is largely unknown. Light colored person show grayish discoloration of the skin of hands, feet, abdomen and face which gives the Indian name Kala-Azar meaning “Black fever”. The parasite is transmitted by sand-fly, Phlebotomus argentipes and other species. This study examined the spatial distribution and seasonal fluctuations of population densities of phlebotomine sand flies and was designed to obtain baseline data on the population trends of Phlebotomus argentipes, P. papatasi, and Sergentomyia spp. The field-based studies on sand flies are not adequate to uncover information required for the control of the leishmaniasis through reduction of vector populations.
