Answer

The median lethal dose 50 (LD50) of various scorpion venoms in mg/kg of a subcutaneous injection into mice and the territorial distribution are listed below (unfortunately, humans are much more sensitive than mice):

  • Leiurus quinquestriatus (Middle East) - 0.25 mg/kg

  • Androctonus crassicauda (Saudi Arabia) - 0.08-0.5 mg/kg

  • Centruroides noxius (Mexico) - 0.26 mg/kg

  • Androctonus mauritanicus (North Africa) - 0.32 mg/kg

  • Centruroides santa maria (Central America) - 0.39 mg/kg

  • Tityus serrulatus (Brazil) - 0.43 mg/kg

  • Buthus occitanus (North Africa) - 0.9 mg/kg

  • Centruroides sculpturatus (Southwest United States) - 1.12 mg/kg

  • Mesobuthus eupeus (Iran) - 1.45 mg/kg

Generally, most lethal scorpions have an LD50 below 1.5 mg/kg.
