Derris is a climbing leguminous plant of Southeast Asia Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China and Taiwan, east of India and north of Australia. The region lies on the intersection of geological plates, with heavy seismic and volcanic activity and the southwest Pacific islands, including New Guinea New Guinea, located north of Australia, is the world's second largest island. It became separated from the Australian mainland when the area now known as the Torres Strait flooded after the last glacial period. The name Papua has long been associated with the island. The western half of the island contains the Indonesian provinces of Papua and. Its roots contain rotenone Rotenone is an odorless chemical that is used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the roots and stems of several plants such as the jicama vine plant. It causes Parkinson's disease-like symptoms if injected into rats. Rotenone kills the freshwater snail Lymnaea stagnalis by attacking the mitochondria, a strong insecticide and fish poison.
Derris scandens in Hyderabad, India The city has been classified as an A-1 city in terms of development priorities, due to its size, population and impact.Also known as Derris powder, it was formerly used as an organic Organic farming is the form of agriculture that relies on crop rotation, green manure, compost, biological pest control, and mechanical cultivation to maintain soil productivity and control pests, excluding or strictly limiting the use of synthetic fertilizers and synthetic pesticides, plant growth regulators, livestock feed additives, and insecticide An insecticide is a pesticide used against insects. They include ovicides and larvicides used against the eggs and larvae of insects respectively. Insecticides are used in agriculture, medicine, industry and the household. The use of insecticides is believed to be one of the major factors behind the increase in agricultural productivity in the 20 used to control pests on crops such as peas. However, due to studies revealing its extreme toxicity, as well as due to the concentration level of rotenone Rotenone is an odorless chemical that is used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the roots and stems of several plants such as the jicama vine plant. It causes Parkinson's disease-like symptoms if injected into rats. Rotenone kills the freshwater snail Lymnaea stagnalis by attacking the mitochondria to which the powder is often refined, experts in ecological and organic growing no longer consider it ecologically sound. Rotenone is still sold in the U.S., however.
Derris root, when crushed, releases rotenone. Some New Guinea natives practice a form of fishing in which they crush the roots and throw them into the water. The stunned or killed fish float to the surface where they can be easily reached.
Despite its toxicity, Derris is used as a food plant by the larvae A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle of numerous Lepidoptera Lepidoptera is an order of insects that includes moths and butterflies. It is one of the most speciose orders in the class Insecta, encompassing moths and the three superfamilies of butterflies, skipper butterflies, and moth-butterflies. Members of the order are referred to as lepidopterans species including Batrachedra amydraula.
