Termiticidal properties of some wood and bark extracts used as wood preservatives

The feasibility of using naturally extracted solutions as wood preservative chemical was tested. Extracts extracted from mimosa (Acacia mollissima Willd.), quebracho (Shinopsis lorentzii Griseb.), and Pinus brutia Ten. bark were used to treat sapwood of Scotch pine (Pinus sylvestris L.), beech (Fagus orientalis L.), and poplar (Populus tremula L.) at two different retention levels (%6 and %12 weight/weight) against the subterranean termite Reticulitermes grassei Clement (Blattodea Rhinotermitidae). The lowest mass loss and highest termite mortality rates were recorded for mimosa and quebracho extract treated woods at the 12% concentration level. Pine bark extract seemed to be ineffective as a wood preservative chemical even at the highest retention level. The results suggest that mimosa and quebracho extracts can be utilized as an environmentally-sound alternative wood preservative chemicals for indoor applications against Reticulitermes grassei.
