Abstract:
Among the scorpions belonging to the Algerian fauna, Androctonus australis (Linnaeus, 
1758), this species has high medical importance. During the year 2020 and 2021, we have 
conducted numerous studies on the ecology and biology of this species based on a sample of 
220 individuals from various biotopes in the region of Ghardaïa which is located in the Sahara 
Desert of Algeria and considered as an arid ecosystem. This study concerned in particular the 
stages of variation and development of the species. The results allow us to define the 
favorable mating season of Androctonus australis which occurs during the autumn period 
when the climatic conditions are favorable, which means relatively low temperatures (about 
18 °C) and winds blowing at a regular speed and in a constant direction. We also noted that 
the species develops a winter diapause of 5 to 6 months, during this period covering the entire 
winter season and a few weeks of spring, the females were inactive and begin their activity 
the end of March with a remarkable interval time before that of the trunks, In spring and 
summer, following parturition, a significant number of juveniles is observed. However, we 
noted that the number of males remains low compared to the females of Androctonus 
australis
