Among the sixteen Iranian Island in the Persian Gulf, Qeshm Island is the biggest and is located in the focus of the important internal and international commercial marinelines. Furthermore, thousands of tourists also visit the Island every year for its natural beauties and the siteseeings. The present research study was carried out during 1998-99 throughout Qeshm Island in order to know the species of scorpions, their abundance, the distribution and control strategy in order to reduce the scorpion stings and to safeguard the visitors as well as the local population.

Methods: Collections were made randomly during the night. Samples were searched by black light and then collected by forceps. A total of 102 scorpions were captured.

Results: The scorpions were identified as Buthotus jayakari numbered 42 specimens (41.17%) and B. leptochelys numbering only 7 specimens (6.86%) belonging to the family Buthidae. Androctonus crassicauda was collected in the most parts of the Island and considered as the dominant species. The sex ratio was 1:1.53 in favor of females. B. leptochelys was rare species and by far restricted in its distribution.

Conclusion: Considering the high population of A. crassicauda and its wide distribution, it is regarded to be responsible for the majority of scorpion stings in Qeshm Island.
