Bornova ve Kemalpaşa ilçelerinde (İzmir), 2015-2016 yıllarında, Memecik zeytin ağaçları (Olea europaea L. cv. Memecik) üzerinde Euphyllura phillyreae Foerster (Hemiptera: Psyllidae)’nin popülasyon değişimi ve biyolojik dönemlerinin durumu incelenmiştir. Zeytinliklerde, E. phillyreae’nin yumurtaları 8 Mart-12 Mayıs, nimfleri 16 Mart-18 Haziran tarihleri arasında bulunmuştur. Zeytin ağaçlarının çiçek salkım oluşumu ve tomurcuklanma başlangıcı dönemlerinde bırakılan ilk yumurtalar, Bornova’da, Kemalpaşa’dan 2-3 hafta önce görülmüştür. Yumurta ve nimf dönemleri sadece mart başı-haziran ortası arasında gözlenmiştir. Yıllara göre mart, nisan ve mayıs aylarının ortalama sıcaklıkları sırasıyla; 2015 yılında, Bornova’da 11.9/14.9/22.6 °C, Kemalpaşa’da 9.6/12.6/20.2 °C; 2016 yılında, Bornova’da 13.4/18.2/21.2 °C, Kemalpaşa’da 11.0/16.9/18.4 °C olmuştur. Nimf sayısı nisan ayının son haftasında en yüksek düzeye ulaşmıştır. Ayrıca, nimfler Bornova’da her iki yılda da haziran ayının üçüncü haftasına kadar (orta-iri yeşil meyve dönemi), Kemalpaşa’da mayıs sonuna kadar (meyve bağlama dönemi) görülmüştür. Erginler yıl boyunca zeytinliklerden toplanmıştır. Yıllara göre değişmekle birlikte, yeni erginler ilk olarak 28 Nisan-29 Mayıs tarihleri arasında, zeytin ağaçlarının kapalı çiçek tomurcuğu, tomurcukta uyanma, çiçeklenme başlangıcı veya %50 çiçeklenme dönemlerinde çıkmıştır. Yaz aylarında ergin popülasyonunun daha yüksek olduğu, sonra giderek azaldığı belirlenmiştir. En az ergin ocak ve şubat aylarında elde edilmiştir. E. phillyreae’nın İzmir’de bir döl verdiği sonucuna varılmıştır.
In the districts of Bornova and Kemalpaşa (Izmir), in the years 2015-2016, Memecik olive trees (Olea europaea L. cv. The population change and the state of biological periods of Euphyllura phillyreae Foerster (Hemiptera: Psyllidae) have been studied on the spine. E. phillyreae’s eggs were found in the olive plants from 8 March to 12 May, and the nimphs from 16 March to 18 June. The first eggs left in the early periods of the formation of the flower shrinking of the olive trees and shrinking were seen in Bornova, 2-3 weeks before Kemalpaşa. Egg and nimf periods were observed only between March and mid-June. The average temperatures for the months of March, April and May according to the years; in 2015, 11.9/14.9/22.6 °C in Bornova, 9.6/12.6/20.2 °C in Kemalpaşa; in 2016, 13. 4/18.2/21.2 °C was 11.0/16.9/18.4 °C in Kemalpaşa. The number of NIMFs reached the highest in the last week of April. Furthermore, the nimphs were seen in Bornova every two years until the third week of June (the middle-earth green fruit period), and in Kemalpaşa until the end of May (the fruit bonding period). They were gathered from olive plants throughout the year. While variing by year, the new adults first appeared between 28 April and 29 May, in the closed flower periods of the olive trees, awakening in the flower period, beginning of flowering or 50% flowering periods. In the summer, the adult population is higher, then it is increasingly decreased. At least the adult was obtained in January and February. The conclusion is that E. phillyreae has given a deal in Izmir.
The occurrence of biological stages and population fluctuation of Euphyllura phillyreae Forester (Hem.: Psyllidae) on Memecik olive trees (Olea europaea L. cv. Memecik) in Bornova and Kemalpaşa districts (İzmir) were investigated during the years of 2015-2016. The eggs of E. phillyreae in olive groves were found between 8 March-12 May and its nymphs between 16 March and 18 June. The first eggs laid during the formation period of flower clusters and at the beginning of budding period in Bornova were seen 2-3 weeks before Kemalpaşa. Egg and nymph stages were only appeared between early March till middle of June. The average temperatures of March, April and May respectively were: 11.9/14.9/22.6 °C in Bornova, 9.6/12.6/20.2 °C in Kemalpaşa in 2015; and it was 13.4/18.2/21.2 °C in Bornova, 11.0/16.9/18.4 °C in Kemalpaşa in 2016. The number of nymphs reached highest level in the last week of April. Also, in both years, nymphs were seen in Bornova until the third week of June (medium-large green fruit period) and until the end of May (fruit set period) in Kemalpaşa. Adults were collected from olive groves throughout the year. Although it changes over the years, new adults firstly emerged during the closed flower bud, flower bud opening, beginning of flowering or 50% flowering periods of olive trees between 28 April and 29 May. It was determined that the adult population was higher during the summer months and then gradually decreased. The lowest adult numbers were obtained in January and February. It was concluded that E. phillyreae was univoltine in Izmir.
