Abstract

Field experiments were conducted at a private mango orchard in Edfu district, Aswan Governorate, Egypt. The orchard was sampled twice monthly from the beginning of August 2020 until mid-July 2022 to study the performance of some mango varieties (Sedik, Balady and Zebda) to infestation with the plum scale insect Parlatoria oleae (Colvee) (Hemiptera: Diaspididae). The total population by pest and the incidence percentages of P. oleae were recorded in January for each of the two mango kinds under study, according to the results. It seemed that the variability in these physical elements in both study years had an impact on the annual changes in the population density during the two years. Overall, it was determined that the Sediek variety of mango was the most favored in terms of population density and the frequency of infestation by P. oleae, the plum scale insect; Zebda and Balady were the next in line.
