Biocidal Activity of a Nanoemulsion Containing Essential Oil from Resin against (Diptera: Culicidae).

This work aimed to prepare a nanoemulsion containing the essential oil of the resin and evaluate its biocidal activities against the different stages of development of the mosquito. Ovicide, pupicide, adulticide and repellency assays were performed. The main constituents were -cymene (27.

Development of nano-emulsions based on Ayapana triplinervis essential oil for the control of Aedes aegypti larvae.

Ayapana triplinervis is a plant species used in traditional medicine and in mystical-religious rituals by traditional communities in the Amazon. The aim of this study are to develop a nano-emulsion containing essential oil from A. triplinervis morphotypes, to evaluate larvicidal activity against Aedes aegypti and acute oral toxicity in Swiss albino mice (Mus musculus).

Larvicidal Evaluation against and Antioxidant and Cytotoxic Potential of the Essential Oil of L. Leaves.

The present study evaluated the antioxidant, cytotoxic, and larvicidal potential of the essential oil of leaves, as well as identified the compounds present in the essential oil. The antioxidant activity was evaluated by the sequestration method of 2,2-diphenyl-1-picrylhydrazyl radical, the cytotoxic activity was evaluated using , the larvicidal bioassay was performed with larvae in the third stage of development of the mosquito, and the identification of the metabolites was performed by gas chromatography coupled to the mass spectrometer (GC-MS). The phytochemical oil analysis showed the presence of 20 compounds, with thymol and -terpinene being the main ones.

Evaluation of larvicidal potential against larvae of Aedes aegypti (Linnaeus, 1762) and of the antimicrobial activity of essential oil obtained from the leaves of Origanum majorana L.

This study evaluated the larvicidal activity of Origanum majorana Linnaeus 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 Linaeus, 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 Leach cytotoxicity.
