Abstract

Bu calisma; Kahramanmaras Ili Merkez Ilcede Sebin , Yalova-4 , Sutyemez-2 ve Sebin cesitlerinden olusan iki farkli ceviz bahcesinde 2012-2013 yillarinda yurutulmustur. Calismada, Isonet-C “(E,E)-8,10-dodecadienol,n-dodecanol,n-tetradecanol % 50, (Z)-11-tetradecenyl acetate % 50” feromon yayicisinin Elma ickurdu [ Cydia pomonella L. (Lepidoptera: Tortricidae)]’na karsi ciftlesmeyi engelleme etkinligi belirlenmistir. Deneme; genis parsellerin karsilastirilmasi seklinde kurulmus olup, denemenin karakterlerini ciftlesmeyi engelleme (CE) ve ilacsiz kontrol (IK) bahcesi olusturmustur. C. pomonella ’nin ergin populasyon gelisimi pherecon tipi eseysel cekici tuzaklarla izlenmistir. A gaclarin guney yonune ve yerden 1.5-2 m yukseklikte olacak sekilde 16 Nisan 2012 ve 08 Nisan 2013 tarihlerinde IK bahcesine 1 ve CE bahcesine de 2 adet eseysel cekici tuzak asilmistir. Calismanin her iki yilinda da, 1000 yayici/ha (5 yayici/agac) dozu uygulanmis ve deneme bahcesine 3000 adet feremon yayici agaclarin farkli yonlerine ve agac tacinin en ustteki 1/3’luk kismindaki uygun dallarina baglanmistir. Deneme suresince CE bahcesindeki 10 adet feromon yayicinin olcumunde, bahcedeki ortalama feromon salim miktarinin 61 mg/saat/yayici oldugu belirlenmistir. Sayim ve degerlendirme, hasat doneminde her bahce icin toplam 1000’er adet meyve uzerinden yapilmis ve CE ile IK bahcelerine ait ortalama kurtlanma oranlari yillara gore sirasiyla; % 5.1-21.3 ve % 4.8-20.1 olarak hesaplanmistir. Calisma sonucunda; ciftlesmeyi engelleme tekniginin Kahramanmaras ili cevizlerinde zararli C. pomonella ’ya karsi 1000 yayici/ha dozunda, organik tarim ve entegre mucadele uretim calismalarinda kimyasal mucadeleye alternatif bir yontem olarak basarili bir sekilde kullanilabilecegi belirlenmistir.

Highlights

Anatolia is the germplasm center of walnut (Juglans regia L.) as well as many other fruit varieties
According to the data obtained from this study, it is determined that mating disruption method will be useful for control of C. pomonella during organic production and for integrated pest management
In a study conducted by Light et al (2005) in California (USA) walnut orchards, number of adult C. pomonella on traps decreased to 90% when 1000 Isomate-C dispensers were applied per ha and the researchers reported that mating disruption method was successful against C. pomonella

Summary

Introduction

Anatolia is the germplasm center of walnut (Juglans regia L.) as well as many other fruit varieties. Numbers of studies were conducted on the biology, damage and management of Codling moth damaging apple and pear in Turkey and in the world until now but there are fewer studies on walnut (Cisneros and Barnes, 1974; Dindar, 1995; Dindar and Ecevit, 1996; Shorey and Gerber, 1996; Light et al, 2005; Anonymous, 2011; Zeki and Özdem, 2013; Canıhoş et al, 2014; Demir and Kovancı, 2015; Anonymous, 2017). This study was conducted in two walnut orchards including Şebin, Yalova-4, Sütyemez and Şebin varieties for the aim of determining the efficacy of mating disruption method as an alternative method to chemical application for the management of Codling moth (C. pomonella)-key pest of walnut orchards in Central district of Kahramanmaraş province in 2012-2013. According to the data obtained from this study, it is determined that mating disruption method will be useful for control of C. pomonella during organic production and for integrated pest management
