Phytochemistry, toxicity and feeding inhibitory activity ofMelissa officinalisL. essential oil against a cosmopolitan insect pest;Tribolium castaneumHerbst

Abstract

Tribolium castaneum considered as an economically worldwide insect pest for agricultural and medicinal aspects. Synthetic chemicals have been used in the management of T. castaneum but their residual problems have been renovated the interest in ecofriendly safe materials such as plant essential oils. In the present study, toxicity and antifeedant effects of an essential oil from Melissa officinalis as well-known medicinal plant investigated against T. castaneum. Chemical analysis indicated g-terpinene, carvacrol and a-terpinene were the main components of essential oil. The essential oil showed strong toxicity on T. castaneum adults at several concentrations and treatment times. The LC 50 values were assessed as 19.418, 18.418 and 16.159 ml/l air after 24, 48 and 72 h exposure time, respectively. Sub-lethal concentrations of essential oil caused significant dose-dependent antifeedant activity. Results indicate M. officinalis essential oil can be suggested as a potential alternative to harmful synthetic chemicals.

Evaluation of the Toxicity of Satureja intermedia C. A. Mey Essential Oil to Storage and Greenhouse Insect Pests and a Predator Ladybird

“…The adults of R. dominica were also susceptible to the fumigation of essential oils extracted from Eucalyptus globulus Labill (24-h LC 50 = 3.529 μL/L), Lavandula stoechas L. (24-h LC 50 = 5.660 μL/L), and Apium graveolens L. (24-h LC 50 = 53.506 μL/L) [ 37 , 38 ]. The fumigation of the essential oils of Lippia citriodora Kunth (24-h LC 50 = 37.349 μL/L), Melissa officinalis L. (24-h LC 50 = 19.418 μL/L), and Teucrium polium L. (24-h LC 50 = 20.749 μL/L) resulted in significant mortality in T. castaneum [ 39 , 40 , 41 ]. The essential oils of Schinus molle L. (48-h LC 50 = 806.50 μL/L) and Artemisia sieberi Besser (24-h LC 50 = 33.80 μL/L) also had notable fumigant toxicity against the adults of T. granarium [ 42 , 43 ].…”

“…The fumigant toxicity of some plant-derived essential oils against O. surinamensis, R. dominica, T. castaneum and T. granarium has been documented in previous studies; it was found that the essential oils of Agastache foeniculum (Pursh) Kuntze, Achillea filipendulina Lam., and Achillea millefolium L. with respective 24-h LC 50 values of 18.781, 12.121, and 17.977 µL/L, had high toxicity on the adults of O. surinamensis [31,[34][35][36]. The adults of R. dominica were also susceptible to the fumigation of essential oils extracted from Eucalyptus globulus Labill (24-h LC 50 [39][40][41]. The essential oils of Schinus molle L. (48-h LC 50 = 806.50 µL/L) and Artemisia sieberi Besser (24-h LC 50 = 33.80 µL/L) also had notable fumigant toxicity against the adults of T. granarium [42,43].…”

Chemical Composition, In Vitro and In Silico Antioxidant Potential of Melissa officinalis subsp. officinalis Essential Oil

“…officinalis has been extensively cultivated for its characteristic lemon-scented oil [25,26]. M. officinalis leaves contain 0.05-0.15% EO in fresh material and 0.1-0.45% EO in dried material, respectively [27]. Due to its digestive and antispasmodic properties, the leaves of M. officinalis are utilized in traditional medicine to treat moderate abdominal disorders and biliary dyskinesia [28].…”

Defense Responses in the Interactions between Medicinal Plants from Lamiaceae Family and the Two-Spotted Spider Mite Tetranychus urticae Koch (Acari: Tetranychidae)

“…It was primarily affected by leaf hair traits, not by female fecundity (host quality). Moreover, plant trichomes produce large amounts of essential oil, substances from the group of secondary metabolites play the role of a defensive mechanism of a plant against the attack of various pathogens or herbivorous [67,[73][74][75]. Presumably, in the present study, the composition of essential oils produced by the tested medicinal plants also influenced the acceptance and plant colonization by spider mites as well as their biological parameters.…”

“…According to Won-Il et al [80], sage oil applied to T. urticae caused more than 80% of adult mortality. However, M. officinalis antifeedant effect was also demonstrated against Tribolium castaneum [74], while O. basilicum showed a contact and fumigant toxicity against stored-food mite Tyrophagus putrescentiae [81].…”
