Leishmaniases are diseases transmitted via an insect vector, the sand fly (Psychodidae: Phlebotominae). In Oran (Salta, Argentina) Nyssomyia neivai is the most prevalent species followed by Migonemia migonei. These sand flies are medical relevance because they were found infected with Leishmania sp. in Argentina and Brazil. Establishing and maintaining of phlebotomine in colony is very important experimental study their biology, behavior and mutual relations with pathogens. The aim of our study was to study the life cycle of Ny. neivai and Mg. migonei under laboratory conditions and constructed a horizontal life table. Sand flies were captured in a peridomiciliary area of Orán city. The blood feeding females were captured on domestic animals and tree bark with mouth aspirators. A female with 5 males were maintained in rearing pots at 25 ± 2 ° C and 85-95% relative humidity. Larval food was a mixture of rabbit feces, fish feed, rabbit feed and adult sand flies food was sugar solution (30%). A total of 82 females were conditioned for oviposition of which 41.4% of female survived and oviposition (p=0.5076). Thirty-two were Ny. neivai and 2 Mg. migonei. The average number of eggs laid per female sand fly were 40.81 (Ny. neivai) and 59.50 (Mg. migonei). A total of 78 adults of Ny. neivai and 27 of Mg. migonei (p
