Two derivatives of nootkatone, tetrahydronootkatone and 1, 1 0- dihydronootkatone, are surprisingly effective as repellents of termites and mosquitos. Tetrahydronootkatone and 1,10~dihydronootkatone were shown to effectively repel termit s at concentrations as low as 2 ~g/ml and 12.5 ~g/ml, respectively. Tetrahydronootkatone was shown to repel mosquitos at a concentration of 5%. Tetrahydronootkatone is an effectiv repellent of termites either by itself or as an addition to other substrates, including mulches i ade from wood products or other cellulose-containing material, Tetrahydronootkatone or 1, 0-dihydronootkatone can be used to protect construction wood from attack by Formosan subte anean termites, either alone or used in combination with other compounds known to repel termites. It is also believed that these compounds will prove effective in repelling ants, ticks, and cockroaches. These derivatives. of nootkatone are non-toxic to humans and other mammals and environmentally safe.
L'invention concerne deux dérivés de la nootkatone, la tétrahydronootkatone et la 1,10-dihydronootkatone, sont des répulsifs efficaces de termites et de moustiques. La tétrahydronootkatone et la 1,10-dihydronootkatone repoussent efficacement les termites à des concentrations aussi faibles que respectivement 2 ?g/ml et 12,5 ?g/ml. La tétrahydronootkatone repousse les moustiques à une concentration de 5%. La tétrahydronootkatone est un répulsif efficace des termites par elle-même ou en addition à d'autres substrats, incluant des paillis fabriqués à partir de produits de bois ou d'autres matériau contenant de la cellulose. La tétrahydronootkatone, ou la 1,10-dihydronootkatone, peut être utilisée afin de protéger le bois de construction contre les attaques par les termites souterraines de Formose, soit seule ou en combinaison avec d'autres composés connus pour repousser les termites. On suppose aussi que ces composés seront efficaces en tant que répulsif de fourmis, de tiques et de blattes. Ces dérivés de la nootkatone sont non toxiques pour les humains et d'autres mammifères et sont sans danger pour l'environnement.
