Distribution and infestation rates of the olive psyllid species (Euphyllura spp., Hemiptera: Psyllidae) in İzmir and Aydın

Abstract

Distribution and infestation rates of the olive psyllid species (Euphyllura spp., Hemiptera: Psyllidae) determined in Aydın and İzmir provinces, which are the most important olive production regions in Turkey between 2015 and 2016. Euphyllura phillyreae Foerster was only founded in İzmir, but both E. phillyreae and E. straminea Loginova were determined in Aydın. E. phillyreae was determined to be the dominant species. The infestation rates in olive groves in two cities between 2015 and 2016 years were 98.5% and 100% in İzmir; 100% and 94.5% in Aydın, respectively. Also infestation rates of the trees in olive groves were 89.4% and 83.4% in İzmir; 93.5% and 75.4% in Aydın, respectively.

Population change and some biological characteristics of Euphyllura phillyreae Foerster (Hemiptera: Psyllidae) in İzmir province

“…Türkiye' de E. phillyreae, E. straminea ve E. pakistanica (Başar 2016, Burckhardt and Önuçar 1993, Drohojowska and Burckhardt 2014, Güçlü et al 1995, Kaplan et al 2016, Kaptan et al 2019, Önuçar 1983), İzmir' de E. phillyreae ve E. straminea türleri saptanmış (Burckhardt and Önuçar 1993), Kaptan et al (2019) E. phillyreae'nin yıl içerisindeki popülasyon değişimini belirlemeye yönelik çalışmalar Bornova ve Kemalpaşa' daki bahçelerde bulunan 40 yaşında Memecik çeşidi zeytin ağaçlarında yürütülmüştür. Bornova' daki bahçede 6x6 sıra arası ve üzeri mesafeli 150, Kemalpaşa' daki bahçede 8x8 sıra arası ve üzeri mesafeli 400 adet ağaç bulunmaktadır.…”
