Diyarbakır ve Elazığ illeri meyve bahçelerindeki Koşnil (Hemiptera:Coccomorpha: Coccidae) türleri

Abstract

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.
