“…Rigani EO presented only one previous assessment as Cx. pipiens repellent that matched present results (Carroll et al, 2017). Finally, Fringed Rue, Monk's Pepper and Fennel EOs, have been extensively studied as repellents against numerous mosquito species, including at least one Aedes species.…”

From Bio-Prospecting to Field Assessment: The Case of Carvacrol Rich Essential Oil as a Potent Mosquito Larvicidal and Repellent Agent

Contemporary legislation tends to increase limitation on the use of all synthetic pesticides, promoting bio-pesticides as a safer alternative. Bio-prospecting efforts for bio-pesticides provide results, which rarely reach the industry. Present essay elaborates on our efforts to chart the path from the laboratory bench to field assessment. Eight Mediterranean wild gathered foods provided the essential oils that were assessed as mosquito control agents against the Asian tiger mosquito (Aedes albopictus). Three Lamiaceae essential oils, derived from Satureja thymbra, Origanum onites, and Thymbra spicata presented carvacrol as principal component. All exhibited DEET-like repellent performance and total larvae mortality defining the carvacrol rich essential oil (CREO) as a promising mosquito control agent. A commercial variety of Origanum vulgare ssp. hirtum, was selected as CREO source and subjected to dose-response and eco-toxicity studies. We have found significant larvicidal (LC 90 of 58,747 mg/L), and repellent (0.2 µL/cm 2) properties, but also severe toxicity (LC 90 of 12,806 mg/L) against Macrocyclops albidus. This last figure was the limit for the larvicidal field assessment; while for the repellent evaluation was used double the minimum indication (0.4 µL/cm 2). CREO was tested per se as larvicidal agent, and emulsified for both repellent and larvicidal field activity. The emulsified CREO's spatial repellent assessment showed maximum efficacy of 86% in day 1 that gradually declined in the following 2 days (81%, 69%). Both emulsified and crude CREO proved to be efficient larvicidal agents, with crude CREO (3 weeks) overrunning slightly the emulsified (2 weeks) in terms of endurance. Conclusively, CREO in its emulsified form may be considered as a promising mosquito larvicidal and repellent agent, applicable in both precautionary and emergency response measures.

Origanum species are mostly distributed around the Mediterranean, Euro‐Siberian, and Iran‐Siberian regions. Since time immemorial, the genus has popularly been used in Southern Europe, as well as on the American continent as a spice now known all over the world under the name “oregano” or “pizza‐spice.” Origanum plants are also employed to prepare bitter tinctures, wines, vermouths, beer, and kvass. The major components of Origanum essential oil are various terpenes, phenols, phenolic acids, and flavonoids with predominant occurrence of carvacrol and thymol (with reasonable amounts of p‐cymen and ‐terpinene) or of terpinene‐4‐ol, linalool, and sabinene hydrate. Many species of Origanum genus are used to treat kidney, digestive, nervous, and respiratory disorders, spasms, sore throat, diabetes, lean menstruation, hypertension, cold, insomnia, toothache, headache, epilepsy, urinary tract infections, etc. Origanum essential oil showed potent bioactivities owing to its major constituents' carvacrol, thymol, and monoterpenes. Several preclinical studies evidenced its pharmacological potential as antiproliferative or anticancer, antidiabetic, antihyperlipidemic, anti‐obesity, renoprotective, antiinflammatory, vasoprotective, cardioprotective, antinociceptive, insecticidal, and hepatoprotective properties. Its nanotechnological applications as a promising pharmaceutical in order to enhance the solubility, physicochemical stability, and the accumulation rate of its essential oils have been investigated. However, Origanum has been reported causing angioedema, perioral dermatitis, allergic reaction, inhibition of platelet aggregation, hypoglycemia, and abortion. Conclusive evidences are still required for its clinical applications against human medical conditions. Toxicity analyses and risk assessment will aid to its safe and efficacious application. In addition, elaborate structure–activity studies are needed to explore the potential use of Origanum‐derived phytochemicals as promising drug candidates.

“…Therefore, new and alternative mosquito control agents are emerging. Plant-derived products including essential oils (EOs) may offer an alternative and effective means of managing populations of mosquitoes [8][9][10][11]. As a part of our ongoing investigation of Turkish medicinal and aromatic plants, we report on the chemical composition of the aerial parts of S. gummiferum subsp.…”

“…The primary method of mosquito control relies on the use of biological and/or synthetic insecticides [6]. Due to long term repeated chemical use, mosquito species have acquired resistance to commonly used insecticides, and especially against commercial pyrethroids [8][9][10][11]. Therefore, new and alternative mosquito control agents are emerging.…”

Mosquitoes are vectors for many pathogens and parasites that cause human diseases including dengue, yellow fever, West Nile, chikungunya, filariasis and malaria which cause high rates of human morbidity and mortality under extreme conditions. Plants are an excellent source for mosquito control agents because they constitute rich sources of bioactive chemicals. They are also biodegradable and environment-friendly. The present study reports on the larvicidal activity of the essential oil of Seseli gummiferum. subsp. ilgazense (Apiaceae) against Aedes aegypti larvae. Essential oil showed 100 and 70% mortality at 125 and 62.6 ppm, respectively, with no mortality at 31.25 ppm. Aerial parts of S. gummiferum subsp. ilgazense were subjected to hydrodistillation to yield 0.6% oil. The essential oil was analyzed by GC-FID and GC-MS techniques. The main constituents in the oil were sabinene (28.8%), germacrene D (9.5%) and α-pinene (7.2%).
