Cotton is an important industrial crop that requires intensive labor and expense. However there are many pest species that affect the yield and quality of cotton production and many insecticides are used to control these pests. Chemical control occurs serious problems on human and environmental health as well as non-target organisms. In addition one of the control methods is natural enemies in biological control. Nabis spp. (Hemiptera: Nabidae) is a natural enemy that can feed on many pest species. In the study sampling was carried out to determine Nabis genus and important species in cotton cultivation areas of Şanlıurfa, Diyarbakır and Mardin provinces. According to results of this study the important species have been identified 72.5% Nabis (Nabis) pseudoferus orientarius Remane, 1962, 20% Nabis (Nabis) punctatus A. Costa, 1847 and 7.5% Nabis (Nabis) ferus (Linnaeus, 1758) species through the ratio of the presence of the species to the collected adult individuals.
