Faunistic study and biodiversity of scorpions in Qeshm Island [Persian Gulf]

Scorpions are known as the most widespread poisonous creatures that cause casualties and death to human. They are distributed in tropical and subtropical areas. 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. 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. 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. 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

[ Economic and Health Impact of Rodent in urban zone and harbours and their Control Methods]

Backgrand: more than thousand of years, Rodents have lived with human especially in the harbours and ships. They not only eat human foods but also make disasters because of chewing of power lines, phone and computer cables. Also they may chew any aluminum, wooden and plastic particles of machineries [machinery's]. Rodent are also vectors, reservoirs and carriers of 40 bacterial, viral and parasitic zooanthroponoses. This paper is proposed to high lighting the importance of control and management of rodent population in urban zone and harbour and to propose the new methods of rodent management

Materials and methods: this study was a review article based on the information and data, which is published in internet, journals and associated research

Conclusions: as a result of this research, wide distribution of rodent in harbours, ship and urban zone is a pandemic problem specially in developing and also developed countries. The strategies and methods of control completely depend on biology and bioecology of rodents, new and integrated management of rodents depopulation, type of ship and its usage, formulation of rodenticide and so on which is discussed in the presentation
