위키페디아 설명
Derris eliptica is a species of leguminous plant from Southeast Asia and the southwest Pacific islands, including New Guinea. The roots of D. elliptica contain rotenone(로테논; 살충제 일종), a strong insecticide and fish poison.
Also known as derris powder and tuba root (in Indonesia),[2] it was formerly used as an organic insecticide used to control pests on crops such as peas. However, due to studies[which?] revealing the extreme toxicity of rotenone to which the powder is often refined, it is unsafe: in spite of its popularity with organic growers.[3][better source needed]
Derris root, when crushed, releases rotenone. Some native residents of Fiji and New Guinea practice a form of fishing in which they crush the roots and throw them into the water.[4] The stunned or killed fish float to the surface where they can be easily reached.[5]
Despite its toxicity, Derris is used as a food plant by Lepidopteran larvae[6] including Batrachedra amydraula.
