Abstract:

 This study was carried out in a total of 40 orchards between the years 2021-2022 in order to determine the harmful hazelnut bud mite species and the contamination rate in the hazelnut orchards in the three districts Akçakoca, Merkez and Cumayeri where hazelnut cultivation is most common in Duzce. Taking into account the size of the hazelnut orchards, the organs of the tree such as leaves, shoots, buds, flowers and fruits were Akçakoca, Merkez and Cumayeri where hazelnut cultivation is most common in Duzce. Taking into account the size of the hazelnut orchards, the organs of the tree such as leaves, shoots, buds, flowers and fruits were examined by visual control method in at least 10 randomly selected quarries in each orchard, and the collected samples were brought to the laboratory with polyethylene bags and recorded. Species identification was made by preparing the preparations of the individuals obtained. In addition, in the samplings, buds were counted in at least 10 quarries in each orchard and on a branch selected from each quarry. When a single individual or damage of the pest is detected in the sampled gardens, that garden was recorded as contaminated and the infection rate was determined. In the study, Phytoptus avellanae Nal. Trombidiformes: Phytoptidae and Cecidophyopsis vermiformis Nal. Trombidiformes: Eriophyidae were identified. Species P. avellanae represent a complex of two cryptic species. In all three districts, it was determined that the pest contamination rate was 100 in the hazelnut orchards and the bud density was above the economic damage threshold. The highest average of cones per branch in the gardens was found in Cumayeri district 16,4 cone numberbranch, followed by Akçakoca district 6,5-9,25 cone numberbranch and Central district 7,16-8,85 cone numberbranch. It has been observed that the hazelnut bud mite population is at a level that requires control and it is among the important factors affecting the yield of hazelnut in recent years.

 Bu çalışma Düzce ilinde fındık yetiştiriciliğinin en fazla yapıldığı üç ilçede Akçakoca, Merkez ve Cumayeri fındık bahçelerinde bulunan zararlı fındık kozalak akar türlerini ve bulaşma oranını tespit etmek amacıyla toplam 40 bahçede 2021-2022 yılları arasında yürütülmüştür. Fındık bahçelerinin büyüklüğü dikkate alınarak örneklemelerde her bir bahçede rastgele belirlenen en az 10ar ocakta gözle kontrol yöntemi ile ağacın yaprak, sürgün, tomurcuk, çiçek ve meyve gibi organları incelenmiş ve toplanan örnekler polietilen torbalar ile laboratuvara getirilmiş ve kaydedilmiştir. Elde edilen bireylerin preparatları hazırlanarak tür teşhisi yapılmıştır. Ayrıca, örneklemelerde her bir bahçede en az 10ar ocakta ve her ocaktan seçilen birer daldaki kozalakların sayımı yapılmıştır. Örnekleme yapılan bahçelerde zararlının bir tek bireyi veya zararı tespit edildiğinde o bahçe bulaşık olarak kaydedilmiş ve bulaşma oranı belirlenmiştir. Çalışmada Phytoptus avellanae Nal. Trombidiformes: Phytoptidae ve Cecidophyopsis vermiformis Nal. Trombidiformes: Eriophyidae olmak üzere iki tür tespit edilmiştir. Phytoptus avellanae türü iki kriptik türden oluşan bir kompleksi temsil etmektedir. Her üç ilçedeki fındık bahçelerinde zararlı ile bulaşma oranının 100 olduğu ve kozalak yoğunluğunun ekonomik zarar eşiğinin üzerinde olduğu saptanmıştır. Bahçelerde dal başına kozalak ortalaması en yüksek Cumayeri ilçesinde 16,4 kozalak sayısıdal tespit edilmiş, bunu sırası ile Akçakoca ilçesi 6,5-9,25 kozalak sayısıdal ve Merkez ilçe 7,16-8,85 kozalak sayısıdal takip etmiştir. Fındık kozalak akar popülasyonunun mücadeleyi gerektirecek düzeyde olduğu ve son yıllarda fındıkta verimini etkileyen önemli faktörler arasında yer aldığı görülmüştür.
