In this study, sapwood of some domestic wood species, maple (Acer pseudoplatanus), juniper (Juniperus foetidissima), sycamore (Platanus orientalis), basswood (Tilia tomentosa), Graveyard cypress (Cupressus sempervirens) and olive wood (Olea europaea), were tested for their natural durability against termite (Coptotermes formosanus) activity. At the end of 21-day exposure period, weight loss, mortality and consumption rates were calculated based on weight differences. While basswood sapwood showed the highest weight lost, olive sapwood was recorded as the most durable wood against Coptotermes formosanus.

Anahtar Kelimeler

Bazı Yerli Ağaç Türü Diri Odunlarının Coptotermes formosanus Termitine Karşı Doğal Dayanıklılığı

Öz

Bu çalışmada, akçaağaç (Acer pseudoplatanus), ardıç (Juniperus foetidissima), çınar (Platanus orientalis), ıhlamur (Tilia tomentosa), servi (Cupressus sempervirens) ve zeytin (Olea europaea) gibi bazı yerli ağaç türü diri odunlarının Coptotermes formosanus termitine karşı doğal dayanıklılığı belirlenmiştir. Yirmi bir günlük deneme süresi sonunda, ağırlık kayıpları, özgül ağırlık ve odun tüketimi arasında bir korelasyon olduğu fakat ölüm oranları ile herhangi bir korelasyon olmadığı belirlenmiştir. Ağaç türleri içerisinde Coptotermes formosanus termitine karşı en yüksek direnci gösteren ağaç türü zeytin olurken, en düşük dirençli ağaç türünün ise ıhlamur olduğu belirlenmiştir.

Anahtar Kelimeler
