Ficus whitefy Singhiella simplex is a pest of Asian origin that causes economic damage to various species of Ficus spp. In this study, the population fuctuation of the parasitoid Encarsia protransvena on S. simplex was investigated in Antalya, Turkey, between August 2018 and August 2020. Yellow sticky traps were hung as one trap per direction of the F. retusa trees, and a total of 120 shoots were sampled from each direction of the F. retusa plants at weekly intervals. On the shoots, S. simplex larval stages, and parasitized larvae were counted. In both years, whitefy adults began appearing on yellow sticky traps in the second half of February, whereas parasitoid adults appeared at the beginning of March. The number of E. protransvena began to increase in May, but the increase was limited over the summer months. The number of E. protransvena in the yellow sticky trap reached its highest level, with 106.5 adults per trap in October 2018 and 120.25 adults per trap in October 2019. In shoot sampling, the highest numbers of E. protransvena larvae and pupae were observed in October 2018 and 2019, with 7.55 and 5.65 individuals per shoot, respectively. In August, September, October, and November of 2018, parasitism rates were recorded as 16, 18, 27, and 34, respectively. In August, September, October, and November of 2019, parasitism rates were observed at 14, 12, 21, and 23%, respectively. The data obtained as a result of this study may contribute to the management of S. simplex.
