Acanthiophilus helianthi (Rossi, 1794) (Diptera: Tephritidae) also known as safflower fly, is an oligophagous species that cause significant damage to safflower plants Safflower, Carthamus tinctorius (L.) (Asterales: Asteraceae), which is among its hosts, is an important energy plant that is drought resistant and has high adaptability. This study investigated the population growth of A. helianthi on five different safflower varieties (Asol, Ayaz, Balcı, Dinçer and Göktürk) in Van Yuzuncu Yıl University, Faculty of Agriculture for two years (2019-2020) in Van province. Result of the study, it was determined that the pest showed a similar population change in both years, the adult individuals were seen at the end of June - mid-August, and their pupae from this date to the beginning of September. It was seen that the insect density was statistically different between the varieties at different sampling dates and the highest adult density was found in variety of Asol pupae in both years, and in Göktürk variety. During sampling with sweep net, 4 parasitoids, Ormyrus sp., M. annulatus, E. acroptilae and Bracon sp., were detected and it was understood in the literature that they were parasitoids of A. helianthi.
