Abstract: The present study was carried out to evaluate an alternative controlling agent for greenhouse pests and the yellow fever mosquito larvae. The potential bioactivity of Licaria puchury-major (Mart.) Kosterm. (“puxuri”) was evaluated here against three most common pests in tropical and subtropical countries: Aedes aegypti Linn. Larvae, Tetranychus urticae Koch. mites and Cerataphis lataniae Boisd. aphids. The essential oil from seeds was analyzed by GC-FID and GC-MS. The major compounds were safrole (38.8%) and eucalyptol (21.7%). Phenylpropanes (51.7%) was the main group of compounds and oxygenated monoterpenes represented 28.8% of the total oil. The essential oil has shown no inhibition of acetylcholinesterase (AChE) in the tested concentrations. However, potential antioxidant activities were evaluated by different methods [DPPH: LD50 = (27.8 ± 1.0) µg/.mL; ABTS: (977.3 ± 25.2) µM TEs/g (Trolox Equivalents); FRAP: (548.2 ± 29.0) µM Fe(II)/g]. A significant larvicidal potential for 24 h of exposure was observed with LD50 = 98.9 µg/mL, being an indicative that the larval mortality may occur by ingestion or contact due to the no inhibition against AChE. Volatile phase effects were evaluated against T. urticae Koch. and C. lataniae Boisd. and LD50 were found about 30.8 and 13.5 µg/mL, respectively. These results are consistent with an octopaminergic effect, since some phenylpropanoids (such as Safrole, identified as the major compound in this work) can block octopamine, a multi-functional, naturally occurring biogenic amine. Then, this study clearly illustrated the efficacy of the investigated seeds, which encourages the development of a new potential natural controlling agent against these common pests due to the abundance of these seeds in the Amazon region and to the high essential oil yield. © 2018 ACG Publications.
