Description
Summary:The larvicidal activity of essential oils (EOs) extracted from , and aromatic plants grown in Vietnam was evaluated on larvae. The EOs were hydro-distilled in a Clevenger-type apparatus. The EOs were analyzed by gas chromatography-mass spectrometry (GC-MS). The mortality rates obtained from the bioassays were used to calculate the lethal concentrations (LC ) of the EOs by the probit analysis method. These essential oils exhibited toxicity to the larvae of . Results were obtained for (LC = 120.6 ppm), (LC = 38.8 ppm), (LC = 104.4 ppm), and (LC = 33.7 ppm). The essential oils of and were found to be the most efficient, and their respective values of LC were 33.7 ppm, 38.8 ppm. In conclusion, this research adds to the growing body of literature on natural larvicides from essential oils against mosquitoes.
