The Survey of Nesting Behavior within Digger Scorpion of Khuzestan Province

Scorpions are the oldest terrestrial arthropodas. Scorpions dig their nest in the ground to protect themselves and their infants from light، high and low tempreture. Regarding habitat، species، depth and the palce of digging، the nest of scorpions would be various، with due regard to the climate of Khuzestan Province and the variety of Scorpion species in this Province، investigation of Scorpion nesting behaviors is an essential issue in Scorpionology. In this research، the nesting behaviors of two types of Scorpions Odothouths bidentatus and Scorpio mauruss were examined. In this Survey، length and width of the nest entrance were measured and small models of the nests were made by means of injecting materials such as cement and chalk in these nests. After the computation of mean، Standard deviation and Standard error of measurment applying T-test and the Significance of error less than%5، the result of measuring width and length of the entrance، different parts of the nest including initial، middle، final and length of the nest of Scorpion s under investigation were compared. To compare the parameters insides the species، nonparametric Freedman method was applied، and also to compare the measured parameters concerning physicochemical properties of Scorpion soilbed، Mann Whitney method was used.
