Abstract: Chaff scale, Parlatoria pergandii (Comstock) (Hemiptera: Diaspididae) is a cosmopolitan and polyphagous pest worldwide. It causes characteristic green spottings on fruits decreasing its market value, desiccate of leaves and branches and at high infestations drop of the fruits. This study was carried out to determine the population dynamics of P. pergandii and its parasitoids in Hatay (Turkey) province on orange, mandarin and grapefruit in 2012-2013. Data revealed that the common abundance was recorded on orange followed by mandarin and the least on grapefruit as the same sorting for the parasitization rate. There were three highly variation periods of the pest and the population reached the maximum during July, August and October in both growing seasons at all citrus species. Pest population was higher on leaves than branches then the fruits, respectively but the parasitization rate was highest on fruits followed by leaves then the branches at all citrus species. It was concluded that the first generation, which was corresponded to the first half of July, must be taken as the basis for the control of the pest.
