BACKGROUND & OBJECTIVES: In Egypt, Phlebotomus papatasi is the main vector of cutaneous leishmaniasis. In nature, P. papatasi feeds on blood from different hosts and sucrose (other sugars) mainly from fig fruits. The aim of this study was to examine the effects of three food regimes on the life table parameters of females mainly the life expectancy as a factor determining the fly's capability for Leishmania transmission.
Plants are promising sources of agents useful for the control of vectors of human diseases including leishmaniasis. The effect of Ricinus communis (Euphorbiaceae) and Bougainvillea glabra (Nyctaginaceae), on transmission of leishmaniasis was investigated using them as diets for Phlebotomus papatasi to monitor their effect on life-history traits. P. papatasi were allowed to feed separately on both plants then offered a blood-meal. Fed-females were observed daily for egg-laying and subsequent developmental stages. P. papatasi was able to feed on B.
