BACKGROUND: Phlebotominae sand flies (Diptera: Psychodidae) are the vectors of leishmaniasis. There are different methods for sand fly collection with different performance. The purpose of the current study was to compare the effect of different traps for collection of Phlebotominae sand flies in three endemic leishmaniasis foci in North Khorasan Province, northeast of Iran. METHODS: Sand flies were collected using seven different traps from three villages, three times each twenty days during peak periods of seasonal activity in 2016. RESULTS: was the most predominant species in the study area. Light trap baited with Carbon dioxide (CLT) and sticky paper trap (SPT) caught 22.6% and 22.3% of sand flies respectively. Animal baited trap (ABT) and white Shannon trap (WST) caught significantly fewer sand flies than the other traps. The sex ratio was different by phlebotominae sand fly species and collection methods. The sex ratio was highest in SPT and lowest in black Shannon trap (BST). Species diversity and species richness in SPT were more than other traps. CONCLUSION: Our findings confirm that CLT and SPT are the most efficient sand fly collection methods. CLT is higher attractive for females and Phlebotomus genus and is an ideal method for monitoring the population of Phlebotomus genus during surveillance. SPT is an inexpensive, convenient and easy to be used to detect the presence of sand flies at low densities and provide a more realistic estimation of sand flies biodiversity.
