摘　　要：This study scrutinized the possibility of finding toxicant or deterrent plant metabolites against the dry wood termite Incisitermes marginipennis(Latreille).Plant deterrent agents act as repellents or antifeedants to prevent wood decay and increase its useful life.The potential of the tree Caesalpinia coriaria(Fabaceae)as a biological source of molecules with deterrent effects against the dry wood termite was assessed by a phytochemical fractionation guided by repellence and antifeedant activities.The gas chromatography-mass spectrometry analysis of the leaf essential oil showed geraniol to be one of the major components and its repellent and antifeedant effects were determined.Geraniol had only an antifeedant effect without affecting the body weight or survival of the dry wood termite.Unlike the leaf essential oil,geraniol did not exhibit a repellency effect.An in-silico approach of the activity of acetylcholinesterase in interaction with geraniol resulted in an affinity energy of−7.5 Kcal/mol.Geraniol interacted with the amino acid tyrosine 324 located in the enzyme’s active site while citronellol(negative control)interacted with tryptophan 83 located adjacent to the active site.These deterring terpenes have not been implemented for the preservation and restoration of wood products exposed to the attack of the dry wood termite.However,they are an important natural control alternative.
