Chemical composition and biological activities of the essential oils from Vitex-agnus castus, Ocimum campechianum and Ocimum carnosum Anais da ABC (AABC)
RICARTE,LARA P.; BEZERRA,GABRIELI P.; ROMERO,NIRLA R.; SILVA,HORLANDO C. DA; LEMOS,TELMA L.G.; ARRIAGA,ANGELA M. C.; ALVES,PÉRICLES B.; SANTOS,MARCELO B. DOS; MILITÃO,GARDENIA C.G.; SILVA,THIAGO D.S.; BRAZ-FILHO,RAIMUNDO; SANTIAGO,GILVANDETE M.P..
Abstract The essential oils obtained by hydrodistillation from fresh leaves of Vitex agnus-castus and Ocimum campechianum, and from fresh inflorescences of Ocimum carnosum were analysed by GC-FID and GC-MS. The major components of V. agnus-castus essential oil were identified as 1,8-cineole (47.9%), terpinyl α-acetate (11.6%), sabinene (11.2%) and caryophyllene oxide (9.7%), while in the O. campechianum essential oil were eugenol (72.1%), β-elemene (6.8%), (E)-caryophyllene (6.4%) and bicyclogermacrene (5.2%). Linalool (79.0%), α-epi-cadinol (5.4%), terpinen-4-ol (3.2%) and 1,8-cineole (2.8%) were the major constituents in the O. carnosum essential oil. The essential oils were subsequently evaluated for their larvicidal and cytotoxic activities. Larval...

Evaluation of the insecticidal activity of essential oils and their mixtures against Aedes aegypti (Diptera: Culicidae) Rev. Bras. entomol.
Ríos,Natalia; Stashenko,Elena E.; Duque,Jonny E..
Abstract The search for new insecticides to control dengue fever, chikungunya, and Zika vectors has gained relevance in the past decades. The aim of the present study was to evaluate the larvicidal action of essential oils (EOs) from Thymus vulgaris, Salvia officinalis, Lippia origanoides, Eucalyptus globulus, Cymbopogon nardus, Cymbopogon martinii, Lippia alba, Pelargonium graveolens, Turnera diffusa, and Swinglea glutinosa on Aedes (Stegomyia) aegypti. The EOs were extracted by microwave-assisted hydrodistillation and characterized by gas chromatography/mass spectrometry (GC/MS). The chemical components of the EOs were identified by linear retention indices and mass spectra. Lethal concentrations (LC50 and LC95) were determined by probit analysis using...

Larvicidal activity of the water extract of Moringa oleifera seeds against Aedes aegypti and its toxicity upon laboratory animals Anais da ABC (AABC)
Ferreira,Paulo M.P.; Carvalho,Ana F.U.; Farias,Davi F.; Cariolano,Nara G.; Melo,Vânia M.M.; Queiroz,Maria G.R.; Martins,Alice M.C.; Machado-Neto,Joaquim G..
In this work, biological effects of the water extract of Moringa oleifera seeds (WEMOS) were assessed on eggs and 3rd instar larvae of Aedes aegypti and on its toxicity upon laboratory animals (Daphnia magna, mice and rats). Crude WEMOS showed a LC50 value of 1260µg/mL, causing 99.2 ± 2.9% larvae mortality within 24 h at 5200µg/mL, though this larvicidal activity has been lost completely at 80ºC/10 min. WEMOS did not demonstrate capacity to prevent egg hatching. After extensive dialyses of the crude WEMOS into watersoluble dialyzable (DF) and nondyalizable (NDF) fractions, only DF maintained its efficacy to kill larvae. Acute toxicity evaluations on daphnids (EC50 of 188.7µg/mL) and mice (LD50 of 446.5 mg/kg body weight) pointed out to low toxicity....

Larvicidal effect of hydroethanolic extract from the leaves of Acmella oleracea L. R. K. Jansen in Aedes aegypti and Culex quinquefasciatus. Repositório Alice
ARAÚJO, I. F. de; ARAÚJO, P. H. F. de; FERREIRA, R. M. A.; SENA, I. D. S.; LIMA, A. L.; CARVALHO, J. C. T.; FERREIRA, I. M.; SOUTO, R. N. P..
Mosquitoes, such as Aedes aegypti and Culex quinquefasciatus, are important vectors of diseases, such as dengue fever, chikungunya fever, Zika virus, and filariasis, and these diseases are public health problems. The present study was carried out to evaluate the larvicidal activity of the hydroethanolic extract from leaves of Acmella oleracea leaves against 3rd instar larvae of the Ae. aegypti dengue vector and the Cx. quinquefasciatus filariasis vector. The hydroethanolic extract caused significant mortality in Ae. aegypti and Cx. quinquefasciatus. After 24 h of exposure to the extract, it was possible to establish the LC50 values for the extract: 11.41 ppm for Ae. aegypti and LC50 32.40 ppm for Cx. quinquefasciatus. The hydroethanolic extract from leaves...

Nematicidal and larvicidal activities of the essential oils from aerial parts of Pectis oligocephala and Pectis apodocephala Baker Anais da ABC (AABC)
Albuquerque,Maria Rose Jane R.; Costa,Sonia Maria O.; Bandeira,Paulo N.; Santiago,Gilvandete Maria P.; Andrade-Neto,Manoel; Silveira,Edilberto R.; Pessoa,Otilia D.L..
The chemical composition of the essential oils from aerial parts of Pectis apodocephala and Pectis oligocephala were analyzed by GC-MS. The essential oils of these species were predominantly constituted by monoterpenes. Geranial (42.9-44.5%), neral (32.2-34.2%) and alpha-pinene (10.7-11.4%) were the main constituents in the oil of P. apodocephala, while p-cymene (50.3-70.9%) and thymol (24.4-44.7%), were the prevalent compounds in the oil of P. oligocephala. The essential oils were tested against the root knot nematode Meloidogyne incognita and Aedes aegypti larvae survival. The results obtained show that both essential oils exhibited significant activity and could be considered as potent natural namaticidal and larvicidal agents.
