Resumo: Essential oil obtained from the leaves of Pittosporum tobira was extracted and its chemical composition and larvicidal effects were studied. Analyses were conducted by gas chromatography and mass spectroscopy (GC-MS) to determine the primary constituents of the essential oil of P. tobira. The yield of P. tobira essential oil (PTEO) was 0.1%, and GC-MS analysis identified its major constituents as undecane (31.11%), 4-methyl-1,3-pentadiene (11.34%), (1,3-dimethyl-2-butenyl)benzene (5.45%), and l-limonene (14.08%). The essential oil had a significant toxic effect against early fourth-stage larvae of Aedes aegypti (L.), with an LC50 value of 58.92 ppm and an LC90 value of 111.31 ppm. Finally, the LC50 and LC90 values of l-limonene were 39.7 ppm and 78.11 ppm. These results could be useful for seeking newer, safer, and more effective natural larvicidal agents against A. aegypti.
