The resistance of Finnish softwood timbers to Macrotermitinae termites was tentatively tested under tropical conditions in Zambia using a field microtest method. (L.) H. Karst. and L. sapwood and heartwood, as well as L. sapwood, and the sapwood of the locally grown exhibited no natural termite resistance. On the other hand, heartwood appeared to be virtually immune and the heartwood of had some resistance. There were also some differences in the resistance of the heartwood of the different individuals tested, which was correlated with the width of the annual rings in the wood samples. The termite species involved were sp. and sp. The possibilities of using different types of Finnish softwood timber in the regions in the tropics where there is a risk of termite damage is discussed.Picea abiesLarix sibiricaPinus sylvestrisPinus kesiya,Juniperus communisP.
