The Resistanceof CCB treated BambooPetung Backer Against Marine Borers

Bamboo is a lignocellulosic material that susceptible to insect attack including marine borers. This paper studies the CCB treated bamboo petung ( Backer) against marine borers in open water environment. Fifteen of fourmeterslongbamboostemwereselectedanddividedintothreeheightpositions:base,middleandtop.Formeachposition, fifteen specimens of 30 cm length and 5 cm width were prepared as untreated samples and another fifteen samples were treatedwith3%CCBusingmodifiedBoucherieprossesforsevendays.Preservativeretentionandpenetrationwererecorded prior to open sea water exposure for six months. The results shows that all samples were attacked by marine borers in variouslevel.CCBtreatedsampleswereclassifiedasmildattack,whileuntreatedsampleswereheavilyattackedbymarine borers.
