Abstract:

Various secondary metabolites are produced in the process of botanic self-defending against harmful organs, even of co-evoluting between botanies and their pest. However, part of these secondary metabolites are of botanical acaricide activation. The author concentrated on problems of the academic study on the plants with acaricidal activities, which would be based on the present research on plants, such as Thymelaeaceae, Meliaceae, Solanaceae, etc. and finally directed a way for the research of the acaricide.
