Hymenopteran parasites (adults) and mobile stages (crawlers, adult males) of white peach scale, Pseudaulacaspis pentagona (Targioni-Tozzetti), were monitored biweekly (1986) or weekly (1987) in a peach orchard from April to December. The scale exhibited three peaks of crawler emergence, and a partial fourth generation was observed in both years. Three species of hymenopteran parasites consistently collected from traps were the primary parasites Encarsia berlesi (Howard) and Aphytis proclia (Walker), and the hyperparasite Marietta carnesi (Howard). Populations of all three parasites showed seasonal peaks of activity that differed in the two years of this study. Winter samples taken in 1985, and from 1987 through 1989 indicated differences between years in the ratio of parasites to hyperparasites overwintering.

The study was conducted In Kalamata, Messinia, province of the Peloponnese, where infestations of Pseudauacaspis pentagona (Targioni Tozzetti) (Hemiptera: Diaspididae) were found on kiwi trees Actinidia deliciosa (Actinidiaceae), peach trees Prunus persica (Rosaceae) and mulberry trees Morus alba (Moraceae). Data on biology and ecology of the scale were recorded by samplings of infested branches of mulberry trees and by examining them in the laboratory, during the years 2016-2018. Pseudaulacaspis pentagona is an oviparous and amphigonic species. The fecundity of the scale fluctuated between 97 and 133 eggs per female. In the area of Kalamata it completed 3 generations per year and overwintered as mated pre-ovipositing female. The main natural enemies of P. pentagona recorded in the area of Kalamata are the coccinellid predators: Chilocorus bipustulatus (L.) and Rhyzobius lophanthae Blaisdell.
