Plant products with deterrent activities can become good, environmentally safe, alternative preservatives to protect, preserve, and treat damaged pinewood. The repellent and anti-feedant effects they have shown are specifically against pinewood borer insects. Therefore, it is advisable to use the natural resources available to adequate them into the control pest management. There is an abundant number of plant species of Eupatorium genus present in the American continent. Interestingly, the phytochemical information of this genus is still very scarce. However, it has been subject to intense phytochemical screening to find secondary metabolites with high potential for medical and technological applications. The main interest is focus in molecules with deterrent activities against pinewood insect borers such as the case of Incisitermes marginipennis. Eupatorium sp natives can produce different types of secondary metabolites, some of them unknown. Moreover, their essential oils exhibit more than a hundred metabolites structurally different, with a huge chemical diversity, but with several pharmacological effects. It is highly possible than in this plant molecular pool, there could be a metabolite with repellent and antifeedant effect against the drywood termite. Key words.
