First, the viability, in vitro, of the essential oils of <em>Artemisia absinthium</em> (wormwood), <em>Mentha</em> × <em>piperita</em> (peppermint), <em>Origanum vulgare</em> (oregano) and <em>Thymus vulgaris</em> (thyme) was assessed. Then, the same essential oils were tested in pot experiments, at concentrations of 0.25% (v / v) and 0.5% (v / v). In <em>in vitro</em> tests, all essential oils were effective in killing the juveniles, resulting in mortality rates of 99.0% at both concentrations. The essential oils of <em>Mentha</em> ×<em> piperita</em>, <em>O. vulgare</em> and<em> T. vulgaris</em> were effective in reducing nematode hatching to about 2.0%. In tests conducted under greenhouse conditions, however, tomato plants treated with the essential oils of<em> A. absinthium</em>, <em>Mentha × piperita</em> and <em>O. vulgare</em> had<br>increased the number of <em>M. javanica</em> eggs and galls. Therefore, despite being highly toxic to nematodes <em>in vitro</em>, some of the essential oils tested in this study increased nematode development.</p&gt;}, number={1}, journal={AGRI-ENVIRONMENTAL SCIENCES}, author={Amora, Deisy Xavier and de Podesta, Guilherme Silva and Nasu, Erica das Gracas Carvalho and Figueiredo, Leonardo Domingues de and Ferreira, Fernanda Carla and Lopes, Everaldo Antonio and Ferraz, Silamar}, year={2017}, month={set.}, pages={15-23} }
