This is essential to access minute information about epidemiology of diseases (Parasite, Vector, Reservior), in order to achieve effective control of disease. One of the basic information in respect of controlling measures, is the knowledge and information of fauna and monthly activities of vectors which is essential, because ignoring of different biological aspects of vectors, could cause failure to control strategies. Methods: This is a descriptive- cross sectional study, carried out in four villages of Bushehr district (2007-2008) which were affected by cutaneous Leishmaniasis. Sand flies were collected by standard sticky traps, and identified by electric microscope, using reliable identification keys. Results: Sixteen species.
