MAJOR MARINE WOOD-BORING ORGANISMS

Abstract

Wood as a natural material has been used in the marine environment as construction material for many centuries. Wood material has many superior advantages compared to other materials. Some of them are renewable sources, its durabilty after treatment by wood preservatives, high resistance and elasticity properties. Although, microorganisms deteriorate the surface of wood material, main hazard is carried out by marine borers. Marine borers are classified by two main groups as molluscs and crustaceans. Major organisms of molluscs are teredinids and pholads, crustaceans are limnoria, sphaeroma and chelura. The main factors that effect the distribution of marine borers are sea water temperature and salinity.

ODUNU TAHRİP EDEN BAŞLICA DENİZ ZARARLILARI

Abstract

Ağaç malzeme, kendine has özellikleri sayesinde yüzyıllardır deniz ortamında yapı ve araç malzemesi olarak kullanılmaktadır. Diğer yapı materyalleriyle kıyaslandığında ahşap malzemeyi üstün kılan çok sayıda avantaj mevcuttur. Bunlardan en önemlileri; yenilenebilir bir kaynak olması, ahşap koruyucu maddelerle emprenye işleminden sonra gösterdiği dayanım, yüksek direnç ve elastiklik özelliğidir. Bununla birlikte, mikroorganizmalar deniz ortamında ağaç malzemenin yüzeyini çürütmelerine karşın esas tahribatı odun delici organizmalar yapmaktadır. Odun delici organizmalar yumuşakçalar ve kabuklular olmak üzere iki gruba ayrılmaktadır. Yumuşakçalar grubuna giren önemli odun zararlısı organizmalar Teredinid’ler ve Pholad’lardır. Odun delici kabukluların en önemli cinsleri ise Limnoria, Sphaeroma ve Chelura’dır. Odun delici organizmaların yayılışını etkileyen en önemli faktörler, deniz suyu sıcaklığı ve tuzluluk oranıdır.
