Aydın İl Merkezinde turunç Citrus aurantium L. (Rutaceae) ağaçlarında bulunan Coccoidea üst familyası ile Aphididae ve Aleyrodidae familyaları (Hemiptera)’ na bağlı türlerin saptanması, bulaşma oranlarının ve doğal düşmanlarının belirlenmesi

Abstract

It was aimed to determine the pest species, their infection rate and their natural enemies on sour orange grown for landscape on Boulevards in three different district of the city center namely, Mugla Boulevard, Ataturk Boulevard and Bati Gazi Boulevard, and samplings were conducted in 2012 and 2013. Leaves and shoots were sampled on the trees and examined under stereo binocular microscope every 15 days in the laboratory to determine their infestation rate. Additionally, adult predators and parasitized pest individuals were also collected during sampling to determine the natural enemies. As a result, Coccus hesperidum (Linnaeus), Ceroplastes rusci (Linnaeus) and Aonidiella aurantii (Maskell) were determined in Coccoidea (Hemiptera) superfamily. Four aphid species, Aphis spiraecola (Patch), Aphis gossypii (Glover), Toxoptera aurantii (Boyer de Fonscolombe), and Myzus (Nectarosiphon) persicae (Sulzer) (Hemiptera: Aphididae) were also identified. Adalia fasciatopunctata (Mulsant), Oenopia (Synharmonia) conglobata (Linnaeus), Adalia bipunctata (Linnaeus), and Coccinella septempunctata (Linnaeus) (Coleoptera: Coccinellidae), and additionally Binodoxy angelicae and Lysiphlebus testaceipes (Hymenoptrera: Braconidae) were found as natural enemies on aphids. Aleurothirixus floccosus was sampled as whitefly, and Cales noacki Howard (Hymenoptera: Aphelinidae) was found to be natural enemy on A. floccosus. The parasitization was the highest in September in both study periods.
