Ips sexdentatus’un Anadolu Karaçamı Ağaçlarındaki Nem İçeriğine Etkisi

Böcekler direkt veya indirekt olarak bitkilerle etkileşim halindedir. Bu nedenle özellikle kabuk böceklerinde konukçu seçimi ve konukçu hassasiyeti bu türlerin popülasyonu ve oluşturacakları zarar açısından önemlidir. Ancak konukçu ağaçların hassasiyeti böcek salgınlarında önemli olup salgınlar ağaçlarda ciddi zararlar meydana getirebilir. Çalışmada, karaçam ağaçlarında, Ips sexdentatus istilasına uğramış ve uğramamış Anatolian black pine ağaçlarından alınan odun örneklerinin nem içerikleri belirlenmiştir. Toplam 29 ağaçtan alınan 174 adet örnekle çalışılmıştır. Örneklerin %58,6’sı böcekli ağaçlardan %41,4’ü ise sağlıklı ağaçlardan alınmıştır. Böcek zararı görmüş ağaçların ortalama nem içerikleri %40,75; sağlıklı ağaçların ortalama nem içerikleri %32,68 olup bu ağaçların nem içerikler istatistiksel olarak farklıdır ve istilalar nem içeriğini olumsuz yönde etkilemiştir. Sağlıklı ağaçlarda kuzey ve güney yönlerinden alınan örneklerin nem içerikleri arasında istatistiksel bir fark bulunamamıştır. Böcek zararı görmüş ağaçlarda kuzey ve güney yönlerinden alınan örnek disklerin nem içerikleri arasında istatistiksel bir fark bulunamazken üç farklı yükseklikten (1.30m, 3.30m, 5,30m) alınan örnek disklerin nem içerikleri arasında istatistiksel bir fark vardır. Ayrıca böcek zararı görmüş ve kuzey yönündeki örneklerdeki nem içeriğinin istatistiksel olarak anlamlı olduğu görülmüştür

The Impacts of Ips sexdentatus on the Moisture Content of Anatolian Black Pine Trees

Insects interact with plants in direct or indirect way. The host selection and host sensitivity especially in bark beetles are important in terms of their population and potential. The sensitivity of host trees is important in beetle epidemic as serious damages may be given to trees during epidemics. The current study, the moisture content of wooden samples taken from Anatolian black pine trees that were damaged by Ips sexdentatus and healty trees has been determined. A total of 174 samples was taken from 29 trees (58,6% from damaged trees, 41,4% from healthy trees). The average moisture content of trees was 40,75% for damaged trees, and 32,68% for healthy trees. The moisture content of these trees is significantly different and invasions have negatively affected moisture content. There is no statistical difference between the moisture content of samples taken from north and south sides of damaged trees, however there is a difference among moisture contents of samples from three different heights (1.30m, 3.30m, 5.30m), but indifferent from north and south
