Abstract:

This study was carried out to determine the species of scale insects and their distribution (Hemiptera: Coccomorpha) in olive orchards in five districts (Edremit, Havran, Burhaniye, Gömeç and Ayvalık) in Edremit Bay Region, Balıkesir Province (Turkey), in 2019 and 2020. The samples were collected from 679 olive orchards at 84 locations in the districts. The following six species belonging to the families Coccidae (3), Diaspididae (2) and Pseudococcidae (1) were recorded during the survey: Filippia follicularis (Targioni Tozzetti), Lichtensia viburni Signoret, 1873, Saissetia oleae (Olivier, 1791) (Coccidae), Leucaspis riccae (Targioni Tozzetti, 1881), Parlatoria oleae (Colvée, 1880) (Diaspididae) and Phenacoccus madeirensis Green (Pseudococcidae). Saissetia oleae was found in many olive orchards as a common species in all districts in Edremit Bay, while L. viburni and P. madeirensis were determined only in olive orchards in Edremit district. At the end of the study, 8.1% of the sampled olive orchards were found to be infested with any of the Coccidae, Diaspididae and Pseudococcidae species.
