THE EFFECT OF MARINE BORERS ATTACK ON SEVEN IRANIAN WOOD SPECIES IN BANDAR ABBAS COASTS

Wood samples of seven Iranian hardwood species including: Beech (Fagus orientalis), Oak (Quercus castaneaefolia), Hombeam (Carpinus betulus), Alder (Alnus subcordata), Oriental plane (Platanus orientalis), Eucalyptus camaldulensis and Babul (Acacia arabica) were treated with Creosote and Celcure. Then the samples were installed in the sea water of Bandar Abbas coast (Persian Gulf) for a period of 36 months. During 9, 12, 18 and 36 months, the samples were inspected according with recommendation of IRG/WP/4432(l985). The results showed that, untreated samples of all species were not resisted to the marine borers. The samples treated with creosote using full cell process increased durability of all species expect Hombeam and Babul. Treated samples with celcure were not resisted very well and after 15 months were destroyed.
