Response of Terminalia mantaly H. Perrier wood to beetles tunneling in Southern Nigeria
2018 - IRG/WP 18-10918
Terminalia mantaly (TM), is extremely susceptible to beetles attack, as evidenced by the many scars and/or tunnels on nearly all the trees in the Southern Nigeria. However, information on the responses of wood to insects tunnelling is poorly known for tropical species. To examine the response of TM stem wood to beetles tunnelling in the University of Port Harcourt, we scheduled field observational...

Study of the effect of extractives on the natural durability of Eucalyptus bosistoana wood
2018 - IRG/WP 18-10928
Wood as a natural material is degradable both by biotic deterioration agents (fungi, bacteria, marine borers, insects) and abiotic (UV and IR radiation, moisture, fire, etc.). The inherent resistance to the attack of the deteriorating agents is defined as the natural durability of the wood. This is an important property when considering the shelf life of wood products exposed to extreme conditions...
