Abstract:The durability of bamboo depends on many factors like the species, edaphic conditions of its growth and also the position of the culm. Bambusa bamboos and Dendrocalamus strictus are the most commonly grown important commercial bamboo of South India. Experiments were conducted to investigate the durability of B. bamboos and D. strictus of these 2 species collected from the dry and wet zones in Karnataka. Durability against termites was tested as per IS: 4833-1968 at the termite test yard at Nallal test yard and observations were taken for a period of 36 months. The 36 month observation indicates that B. bamboos and D. strictus collected from the dry zone were more resistant to termites. The durability test against fungi was conducted as per standard under laboratory conditions by using the white rot and brown rot fungus. The results revealed that in D. strictus, culms of wet zone are more durable when compared to culms of dry zone, and in case of B. bamboos, dry zone culms are more durable than those of the wet zone. However, the length wise durability of selected bamboos against termites and fungi followed a fixed pattern where the bottom portion of culm showing more durable followed by the middle and the top portion
