Determination of chemical composition and fumigant insecticidal activities of essential oils of some medicinal plants against the adults of cowpea weevil, Callosobruchus maculatus. Kahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 21(5), 708-714.2619-9149https://dx.doi.org/10.18016/ksudobil.386176https://hdl.handle.net/20.500.12483/90Chemical composition and fumigant insecticidal activities of essential oils obtained from oregano Origanum syriacum L.), lavender (Lavandula angustifolia L.), sage (Salvia officinalis L.,), fennel (Foeniculum vulgare Mill.) and laurel (Laurus nobilis L.) plants were investigated against the adults of cowpea weevil, Callosobruchus maculatus (F.) (Coleoptera: Bruchidae). Based on GC-MS analysis, total number of compounds determined in oregano, lavender, sage, fennel and laurel essential oils were 25, 33, 23, 23, 42, respectively. Carvacrol (66.66%), trans-anethol (79.17%), 1,8- cineole (50.0%), camphor (30.46%) and linalyl acetate (35.66%) were found as the most abundant compounds, respectively. Bioassay results revealed that essential oils, at 30.0 or 40.0 µg ml-1 air, resulted in 100% adult mortality of C. maculatus. Insecticidal activity was increased in response to increased concentration of essential oil. Among the essential oils tested, oregano showed the highest fumigant toxicity at relatively lower concentration (30.0 µg ml-1). Complete adult mortality (100%) caused by fennel, laurel, sage and lavender essential oils at the concentrations of 40.0 µg ml-1 air. The LC50 and LC90 values for each essential oil were estimated by using probit analysis. The lowest LC50 value was estimated for sage essential oil (8.79 µg ml-1) followed by oregano (11.17 µg ml-1), lavender (11.64 µg ml-1), laurel (13.59 µg ml-1) and fennel (17.46 µg ml-1), respectively. The results revealed that plant essential oils might be used in research aiming the development of new environmental friendly control agents against stored-product pests such as cowpea weevil.Origanum (Origanum syriacum L.), lavanta (Lavandula angustifolia L.), adaçayı (Salvia officinalis L.), rezene (Foeniculum vulgare Mill.) ve defne (Laurus nobilis L.) bitkilerinden elde edilen uçucu yağların kimyasal bileşenleri ve fümigant insektisit etkinliği bakla tohum böceği Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) erginlerine karşı araştırılmıştır. GC-MS analiz sonucuna göre, origanum, lavanta, adaçayı, rezene ve defne bitki uçucu yağlarında sırasıyla 25, 33, 23, 23, 42 adet bileşen belirlenmiştir. Carvacrol (%66.66), trans-anethol (%79.17), 1,8- cineole (%50.0), camphor (%30.46) ve linalyl acetate (%35.66) bu bitkilerin uçucu yağlarında ana bileşenler olarak belirlenmiştir. Biyolojik etkinlik çalışmaları tüm uçucu yağların 30.0 ve 40.0 µg ml1 hava konsantrasyonları C. maculans erginleri üzerinde %100 ölümlere neden olduğunu göstermiştir. Uçucu yağların insektisit etkinliği artan konsantrasyonlara bağlı olarak artış göstermiştir.eninfo:eu-repo/semantics/openAccessCallosobruchus MaculatusEssential OilStored PestsFumigant ActivityBioinsecticideCallosobruchus MaculatusUçucu YağDepo ZararlısıFfumigant EtkiBiyoinsektisitDetermination of chemical composition and fumigant insecticidal activities of essential oils of some medicinal plants against the adults of cowpea weevil, callosobruchus maculatusBazı tıbbi bitkilerden elde edilen uçucu yağların kimyasal bileşenlerinin belirlenmesi ve börülce tohum böceği, callosobruchus maculatus erginlerine karşı fümigant insektisidal aktivitelerinin belirlenmesiArticle21570871410.18016/ksudobil.386176WOS:000457128500010N/A
