Özet: The study was carried out in 2006 and 2007 in order to determine damage status and parasitoids of harmful Hypera varialis (Herbest, 1975) in alfalfa areas of Diyarbakır, Şanlıurfa and Mardin provinces.It has been observed that alfalfa weevil has caused considerable damage in the alfalfa areas and this damage has increased especially in the period up to the first sowing. At the end of the study, Bathyplectes curculionis (Thomson) were determined as parasitoid species on the pest. At the end of the study, a total of 2,289 alfalfa weevil were cultured and 66 parasitoids were obtained.In all of the areas where the study was done, B. curculionis speies spread.The parasitization rate of B. curculionis on the alfalfa weevil ranged from 0.55% to 22.22%. At the locations where the study was done; the highest rate of parasitization was determined as 22.2% on 12.04.2007 in the district of Kızıltepe, Mardin.The results of the study are also important in the management against alfalfa pests in terms of biological control.
