This study was carried out in order to determine the predator and parasitoid species that feed on soft scale insect (Hemiptera: Coccidae) species in orchards of Diyarbakır and Elazığ Provinces in Turkiye in 2017 and 2018. Visual identification and rearing methods were used. Eight predatorory species belonging to the families Coccinellidae (4) and Cybocephalidae (1) (Coleoptera), Forficulidae (2) (Dermaptera), and Chrysopidae (1) (Neuroptera), were detected. In addition, 14 parasitoid and 2 hyperparasitoid species from the families Encyrtidae (14), Aphelenidae (1) and 2 Pteromalidae (1) (Hymenoptera) were collected. Among the parasitoid species, Metaphycus ater, M. luteolus, M. chermis and M. unicolor (Hymenoptera: Encyrtidae) are first records for the insect fauna of Türkiye.

This study was carried out in order to determine the soft scale insects (Hemiptera: Coccomorpha: Coccidae) species, their host plants, distribution areas, densities and infestation rates on fruit production areas of Diyarbakır and Elazığ Provinces in 2017-2018. As a result of the study, 7 soft scale species were determined on 12 fruit plants. The most common species and the widest host plant range was Parthenolecanium corni (Bouché, 1844) in the study areas. Sphaerolecanium prunastri (Boyer de Fonscolombe, 1834) and Didesmococcus unifasciatus (Archangelskaya, 1923) were determined to be the most important species in the region. Didesmococcus unifasciatus caused heavy infestation on almond, Prunus dulcis (Mill.) (Rosales: Rosaceae) trees (Scale 4) at rates of 3.1% and 0,9% in Çınar district of Diyarbakır and Sivrice district of Elazığ, respectively. Sphaerolecanium prunastri caused heavy infestation on apricots, Prunus armeniaca L. (Rosales: Rosaceae) at rates of 3.8% and 4.6% in Elazığ's Central and Baskil districts, which have significant apricot production areas.
