The Caatinga is the only biome restricted to the Brazilian territory, occupying basically the Region Northeast, with some areas in the state of Minas Gerais. Caatinga vegetation does not have green exuberance rainforests and the dry aspect of the physiognomies dominated by cacti and shrubs suggests low diversification of fauna and flora. For the preparation of this study, which consists of building a bibliographic summary of the main groups of parasitoids of the Order Hymenoptera (Parasitica Hymenoptera) collected in the Caatinga biome, a bibliographic search was carried out that contained published works on the following aspects: Definition Caatinga, Characteristics Hymenoptera, Characteristics Parasitica Hymenoptera, Main Superfamilies, and Families and Studies carried out and Main genera or species, during the period from December 2019 to January 2020. Although still incipient, some surveys on fauna and flora have been carried out in this type of vegetation, but many have ignored insects, which can be considered the group with a great contribution to the essential processes of ecosystems.
