Abstract
This study would select native plant's species that have been scientifically validated. We collect its provenance and the establishment of the wild gene pool. Our works have that collecting native species of medicinal plants, planning in ex situ gene pool, planting, monitering, and management in plants and gene gardens, and applications in pest prevention and control of medicinal plants. The benefits are expected that establishment in ex situ gene pool of native medicinal species and evaluation in biological products about natural pest prevention. The Experimentsof termite control (Coptotermes formosanus and Odontotermes formosanus) using essensil oil of Litsea cubeba and hydrosol of Cinnamomoum osmophloeum were conducted. The mortality of both two termite species reach 100% in 3 days after the treatments of essensil oil and hydrosol.
