Faunistic Composition and Spatial Distribution of Scorpions in North Khorasan Province Northeast of Iran.

BACKGROUND

Scorpions pose one of the most important public health and medical problems in tropical and subtropical regions of the world, especially in developing countries. This study was conducted to determine the fauna and spatial distribution of scorpions.

METHODS

In this descriptive study, scorpions were captured using ultra-violet (UV) light, pitfall traps and digging methods in North Khorasan Province, northeastern Iran in 2017. After being encoded, the collected scorpions were stored in plastic containers of 70% ethanol and then transferred to the medical entomology lab of Tehran University of Medical Sciences for species identification based on morphological keys. In addition, Arc Geographic Information System (GIS) 9.3 software was utilized for mapping spatial distribution of scorpions.

RESULTS

Overall, 143 scorpions were captured and identified. All of collected scorpions belonged only to Buthidae family. They were also classified into four genera (, , , ) and five species: (59.44%), (16.78%), (12.59), () (9.09%), and (2.10%). Furthermore, spatial distribution of scorpions was performed in this area.

CONCLUSION

Regarding the diversity, high frequency and wide geographical distribution of scorpions and their long-term seasonal activity in this area, the probability of occurrence of scorpion sting is high. Therefore, in order to prevent the occurrence of this public health problem, health educational programs be implemented by health- care providers in the area.
