The effects of the essential oil and hydrolate of canelo (Drimys winteri) on adults of Aegorhinus superciliosus in the laboratory
Drimys winteri (Magnoliids: Winteraceae), a native Chilean species, has potential for use as a botanical insecticide. This species contains chemicals with biological activity, such as isoprenoids and polyphenols. In this study, the effects of the essential oil and hydrolate of D. winteri on adults o...
