The chemical composition of the essential oils from leaves, stalks and inflorescences of Croton zehntneri obtained by hydrodistillation were analyzed by GC-MS and CG-FID. E-Anethole was the main component of the essential oils of all plant parts. Essential oils of leaves, stalks, inflorescences and E-anethole were tested at different concentrations against instar III larvae of Aedes aegypti and showed LC50 values of 56.2 ± 0.3, 51.3 ± 0.3, 57.5 ± 0.1 and 69.2 ± 0.5 μg/mL, respectively.

ABSTRACTThis study evaluated the larvicidal activity of O. majorana essential oil, identified the chemical composition, evaluated the antimicrobial, cytotoxic and antioxidant potential. The larvicidal activity was evaluated against larvae of the third stage of Aedes aegypti, whereas the chemical composition was identified by gas chromatography coupled to mass spectrometer, the antimicrobial activity was carried out against the bacteria Pseudomonas aeruginosa, Escherichia coli and Staphylococcus auereus, the antioxidant activity was evaluated from of 2.2-diphenyl-1-picryl-hydrazila sequestration and Artemia salina cytotoxicity. Regarding to the results, the larvicidal activity showed that O. majorana essential oil caused high mortality in A. aegypti larvae. In the chromatographic analysis, the main component found in O. majorana essential oil was pulegone (57.05%), followed by the other components verbenone (16.92%), trans-p-menthan-2-one (8.57%), iso-menthone (5.58%), piperitone (2.83%), 3-octanol (2.35%) and isopulegol (1.47%). The antimicrobial activity showed that E. coli and P. aeruginosa bacteria were more sensitive to oil than S. aureus, which was resistant at all concentrations. Essential oil did not present antioxidant activity, but it has high cytotoxic activity against A. salina.

The essential oils obtained by hydrodistillation of the leaves, stems, and shoots of Tephrosia toxicaria Pers (Papilionaceae) were analyzed using GC and GC/MS. Germacrene D was the major component (20.7-33.3 %) of the oils of leaves and shoots, whereas spathulenol was the main constituent (42.3%) of the stem oil. The essential oils from the leaves and stems, when tested for activity against mosquito larvae (Aedes aegypti), gave LC 50 values of 81.3 ± 2.9 and 63.1 ± 1.0 ppm, respectively.

Significant Mortality

The chemical composition and larvicidal activity of essential oils derived from the leaves and rhizomes of Zingiber montanum (J. Koenig) Link ex. A. Dietr. were reported. The main compounds in the leaf oil were -pinene (13.8%), -phellandrene (11.3%) and -pinene (7.3%) while the rhizome oil was dominated by sabinene (41.1%), terpinen-4-ol (22.7%) and (E)-nerolidol (14.3%). The minimum lethal concentration (larvicidal activity) LC50 of the rhizome oil at 24 h against Aedes albopictus was 35.17 μg/mL, while LC50 values of 32.20 μg/mL and 31.12 μg/mL were obtained against Aedes aegypti and Culex quinquefasciatus respectively. At 48 h the oil displayed larvicidal action with LC50 values of 23.18 μg/mL, 25.58 μg/mL and 18.99 μg/mL respectively towards Ae. albopictus, Ae. Aegypti and Cx. quinquefasciatus. The leaf oil did not exhibit significant mortality and larvicidal action. The results indicate the potential of rhizome essential oil of Z. montanum as a source of larvicidal agent.

Meta Analyses

The Aedes aegypti is responsible for the transmission of arboviruses, which compromise public health. In the search for synthetic product alternatives, essential oils (OEs) have been highlighted by many researchers as natural insecticides. This systematic review (SR) was performed according to PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and its objective was to evaluate studies addressing OEs with larvicidal properties against Ae. aegypti, through electronic database searches (Pubmed, Science Direct and Scielo), covering an overview of the plant sources OEs, which plant parts were used, the extraction methods, analytical techniques, major and/or secondary constituents with greater percentages, as well as the LC50s responsible for larval mortality. Following study analysis, plants distributed across 32 families, 90 genera and 175 species were identified. The Lamiaceae, Myrtaceae, Piperaceae, Asteraceae, Rutaceae, Euphorbiaceae and Lauraceae families obtained the highest number of species with toxic properties against larvae from this vector. Practically all plant parts were found to be used for OE extraction. Hydrodistillation and steam distillation were the main extraction methods identified, with GC-MS/GC-FID representing the main analytical techniques used to reveal their chemical composition, especially of terpene compounds. In this context, OEs are promising alternatives for the investigation of natural, ecologically correct and biodegradable insecticides with the potential to be used in Ae. aegypti control programs.
