Abstract:
Our research is to know both the quality and quantity of scorpions in Ghardaia, this research is applied on three
station:Mansoura as reg,Sebseb represent a palm and Metlili as an urban station. During seven month, we gather 100
sample of scorpions, all being from the same family of Buthidae, which are Androctonus amoreuxi, Andrcotnus
australis, Androctonus aeneas, Buthus saharicus et Buthacus samiae. That is 17.85% of the species declared in Algeria.
Andrcotnus australis is the most existing one in the region of Ghardaya (60%) followed by Androctonus amoreuxi with
34%, where as the three other species B. samiae, A. aeneas and B. saharicus are less than 3%. the results of Relative
abundance of species reveals that A. australis is the most dominant sample in both urban station and palms. on the other
side A. amoreuxi is more existing in the reg with 76.67% . concerning the origin of A. aeneas is the reg but found in urban
station with a least percentage (05%). for B. samiae and B. saharicus are rare in our research.
The value of Shannon-Weaver Index in Ghardaia Showed that this region is a diverse of Scorpionic fauna in which there
is unbalance between species. The reg is the most diverse (1.11bits) where as in the palms there is certain balance in
species.
At least The factorial analysis of the correspondences, applied to the species caught in the region of Ghardaia, reveals the
existence of three species / biotopes affinity groups. A. amoreuxi in palm,A. aeneas in urban biotope, the two other species
B. samiae and B. saharicus in the reg. Andrcotnus australis is an omnipresent species
