“…Rabenh. and Peltigera rufescens (Weiss) Humb revealed other lichen species that was effective on S. granarius (Emsen et al, 2015). In that study where concentration-dependent insecticidal activity was observed, median lethal concentration (LC 50 ) values of L. vulpina, L. muralis and P. rufescens were 0.51, 0.67 and 0.33, respectively.…”

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.

“…Based on this, some studies demonstrated that the toxicity of extracts isolated from lichen samples against pests was related to their components (Emmerich et al, 1993;Balaji et al, 2007;Cetin et al, 2008). Extracts isolated from different lichen species might have different toxicity levels, which can be attributed to their different chemical composition (Sahip et al 2008;Yildirim et al 2012;Emsen et al 2015). Therefore, lichens can be potential sources of natural compounds for pest management.…”

Efects of Usnic, Barbatic and Fumarprotocetraric acids on Survival of Nasutitermes corniger (Isoptera: Termitidae: Nasutitermitinae)

et al. 2018

Lichens (Algal-Fungal association) synthesize unique chemical substances with different biological activities. Three pure lichen compounds were assayed to evaluate their potential insecticidal activity against the termite Nasutitermes corniger on Petri dishes. Usnic, fumarprotocetraric and barbatic acids were isolated and purified from the lichens Cladonia substellata, C. verticillaris and Cladia aggregata, respectively, using thin-layer and high-performance liquid chromatography for attesting their purity. Nuclear proton magnetic resonance and infrared spectrophotometry was used for their chemical characterization. After exposure, mortality of termites (workers and soldiers) was determined during 11 days period. The termiticidal effect was influenced by the exposure time and the type of member colony. The results showed that lichen substances, tested at 5, 7 and 10 mg mL-1, have a termiticidal activity (~100%) on worker termites after 8th days of treatment, in comparison with controls. However, no significant effect on soldiers was found. These findings indicate that usnic, fumarprotocetraric and barbatic acids are potential compounds for use in the control of this urban pest.

“…Diseases such as malaria, dengue, yellow fever, Japanese encephalitis, chikungunya, and filariasis are transmitted through mosquito vectors. Hence, control of insects is a key factor in the management of crop loss and in the prevention of human diseases that are transmitted through insect vectors (Chen and Wilson, 2005;Dar and Wani, 2010;Ghaly and Edwards, 2011;Oberemok et al, 2015;Ricci et al, 2012;Singh et al, 2015;Verma et al, 2009). The management of these insect pests is commonly achieved using synthetic chemicals.…”

“…Microorganisms (such as bacteria, fungi, and viruses) and natural products including lichens and their metabolites appear to be promising as biopesticides. Biopesticides can replace, at least in part, few of the hazardous chemical agents when used in integrated pest management approaches (Cetin et al, 2008;Ghosh et al, 2012;Gupta and Dikshit, 2010;Kumar, 2012;Nanayakkara et al, 2005;Oliveira et al, 2014;Patel et al, 2016;Ramanujam et al, 2014;Rodriguez-Saona et al, 2016;Verma et al, 2009;Vijayakumar et al, 2010). In this review, a detailed literature survey was carried out to compile information available on the insecticidal activity of lichens and lichen metabolites by referring journals and search engines such as Google Scholar, PubMed, and ScienceDirect.…”

Insecticidal efficacy of lichens and their metabolites - A mini review

Interest in natural products possessing insecticidal activity is increased because of the drawbacks such as high cost, environmental pollution, effects on non-target organisms, and the emergence of resistant pests that are associated with the use of synthetic insecticides. Lichens are composite organisms comprised of a photobiont and a mycobiont. Lichens are used traditionally worldwide and many studies have shown the promising pharmacological properties of lichens, including insecticidal activity. The present review highlights the potential of lichen extracts and their metabolites as insecticidal agents. An extensive literature survey carried out revealed promising insecticidal properties of solvent extracts and metabolites of lichens against plant pests and insect vectors that transmit human diseases. Lichen metabolites such as usnic acid, atranorin, vulpinic acid, fumarprotocetraric acid, barbatic acid, norstictic acid, and diffractaic acid exhibit insecticidal activity. It appears from the literature survey that lichens and their metabolites can be employed as insecticidal agents to prevent and control insect pests that cause damages to plants and transmit diseases such as malaria, dengue, filariasis, and others.
