Abstract: Abstract Siting of buildings in rural urban development requires that the prevalence of termite activities is considered. The severity of termite activities across 18 selected locations within the FUTA campus was investigated. Defect-free samples of Pterygota macrocarpa wood species prepared according to ASTM D3345-17 (2017) were used as baits for assessing the severity of termite activities. The termite severity probability map of the campus area was prepared with the results obtained from the ASTM D3345-17 visual rating and corresponding gravimetric weight loss data. Results revealed the presence of four termite species within the FUTA campus, namely Macrotermes subhyalinus Rambur, Amitermes evuncifer Silvestri, Ancistrotermes cavithorax Sjöstedt, and Microtermes spp.; the latter being the most prevalent. Areas where Macrotermes subhyalinus Rambur were present experienced higher severity and aggressive termite activities with lower visual ratings and higher weight loss values. Supporting soil property data shows that only the soil bulk density had a strong positive correlation with the severity of termite activities with rs = 0.808 and P = 0.001. The termite severity probability map from these data revealed active ongoing termite activities with sharp transitions observed between the regions belonging to the different severity (color coded) levels. This study has reinforced the necessity for estate developers to carry out termite severity assessment in order to recommend appropriate constructional techniques that will ensure the protection of wood in service.
