ABSTRACT
Scorpions are very ancient animals, and several fossil species are described. The World Health Organization listed species from the genera: Centruroides, Tityus, androctonus, Buthus, Buthotus, Leiurus and Parabuthus, all belonging to the family of BUTHIDAE, as capable of causing clinically significant envenoming. Scorpions are Arthropoda of the class Arachnida and constitute the order of Scorpiones, with nine living families: Bothriuridae, Buthidae, Chactidae, Chaerilidae, Diplocentridae, Ischnuridae, luridae, Scorpionidae and Vaejovidae. Chemical control has some problems: scorpions have the ability to hide for several months. The use of residual insecticides in a kerosene solvent (DDT, Chlordane, Lindane) is recommended. First aid for scorpion sting varies with the region and type of scorpion. Application of a pressure immobilisation bandage, as used for some snakebites may delay venom absorption, but also may intensify local pain. Antivenom therapy is most often used in children, depending on the seriousness of symptoms.
