Abstract
Leishmaniasis is considered endemic in 82 countries, including Iran. In order to control the vectors of leishmaniasis, entomological studies, such as fauna, seasonal abundance, nocturnal activity, sex ratio, resting site, etc, are necessary. In this investigation, the species composition of sandflies. and the seasonality and nocturnal activity, sex ratio, and resting site, of Phlebotomus papatasi and P. sergenti, for implementation of future control measures, were surveyed in northeast Shiraz City, southern Iran. Two thousand, five hundred (2,500) adult sandflies were collected from internal and external fixed places by sticky trap. SPSS version 1.3 software was used to analyze the data. Meteorological data were obtained from the meteorological organization in Shiraz. In this investigation, a total of 4 species were recorded: P. papatasi, P. sergenti, Sergentonmyia sintoni, and Ser. dentata. Peak abundance of both P. papatasi and P. sergenti occurred in September, and declined by December. Between sunset and sunrise, the maximum and minimum abundance were found to be at 20 00 hour, and 05 00 or 06 00 hour, respectively. The sex ratio (F/M) of the P. papatasi varied from a high ratio of 10.9: 1 in October, to a low ratio of 1.2: 1 in June. The abundance of sandflies in the external regions was significantly more (p<0.05) than the internal regions in all months except May and June. Using the results of this investigation, health workers in this area can better manage the control and prevention of cutaneous leishmaniasis.
