Use of lichens as natural insecticide

Agriculture has become one of the greatest sources of employment for mankind from the past to the present. The products obtained in this area provide a significant contribution to the national economies. However, the number of organisms causing the decline in crop yield is quite high. The preferred applications for combating harmful organisms are the use of chemical insecticides. However, the high level of side effects of these insecticides led researchers to alternative study areas. Insecticide production through natural products that is under the title of biological struggle, is within popular areas. Lichens are also materials for natural insecticide sources due to their unique constituents in the constructions. For many years, the toxic effects of lichens utilized in many fields on different insect species have been tested through their extracts and pure components. At this point, it is noteworthy that while high yield is obtained from lichens, the studies are predominantly carried out on the extracts. In the light of all these studies, it will be contributed to biological insecticide production stage by increasing of the studies performed on determination of the active components in lichens showing insecticidal activity on different species and on mechanisms of action in insects
