## Background: The encapsulated essential oils (eos) of piper aduncum l. and piper hispidinervum c. dc. in gelatin nanoparticles were evaluated against aedes aegypti linn., tetranychus urticae koch and cerataphis lataniae boisd. ## Results: Encapsulation efficiency of the eos was measured for absolute concentrations of 500 μg ml (79.2 and 72.7%) and 1000 μg ml (84.5 and 82.2%). the loaded nanoparticles were nearly spherical and well dispersed. the nanoparticles loaded with p. hispidinervum eo had an average size of 100 ± 2 nm, while the nanoparticles containing p. aduncum eo ranged from 175 ± 4 to 220 ± 4 nm. according to zeta potential analysis, the nanoparticles loaded with p. hispidinervum and p. aduncum eos presented values around -43.5 ± 3 and -37.5 ± 2 mv respectively. the controlled release of eos was described by the anomalous mechanism of korsmeyer-peppas. both encapsulated eos reached lethal dosages within 24 h of exposure and total mortality of the tested pests. ## Conclusion: The present work successfully developed gelatin-based nanoparticles that served as carriers for the eos of p. aduncum and p. hispidinervum to be applied as a sustainable control tool of a. aegypti,
