<br/><br/> The potential of Cacao Pod Husk (CPHBO) was determined in terms of its effectiveness against wood destroying termites such as the subterranean termites (Microcerotermes losbaņosensis and Coptotermes gestroi) and dry wood termites (Cryptotermes dudleyi and Cryptotermes cyanocephalus). Bio-oil was obtained by maceration process with a 7:3 acetone-water solvent which gives a 30.5% yield of bio-oil. FTIR spectral analysis showed that the main constituents of the bio-oil are phenolic compounds and carboxylic acids. The insecticidal characteristics of the bio-oil against subterranean (Microcerotermes losbaņosensis and Coptotermes gestroi) and dry wood termites (Cryptotermes dudleyi and Cryptotermes cyanocephalus) were investigated. The bio-oil was prepared in various concentrations such as 5%, 25%, 50%, 75% and 100% to test the effectivity against two types of termites which indicates that the increase in concentration at 75%, the mortality of Microcerotermes losbaņosensis also increases but due to the viscous state of the 100% concentration that serves as a pure extract, the mortality decreases.--Author's Abstract
