AB <p>Laboratory bioassays were conducted to evaluate the acaricidal activities of the ethanolic extract of&nbsp;<em>Jatropha curcas&nbsp;</em>L. leaves (Family: Euphorbiaceae) against adult females of oriental red mite,&nbsp;<em>Eutetranychus orientalis</em>. The leaf dip technique and direct application were adopted to assess the toxicity, fertility, repellency and ovicidal effects of different doses (0.1&ndash;10 mg/mL) of the ethanolic extracts of&nbsp;<em>J. curcas</em> L. leaves. We found that this extract increased mortality and reduced fecundity in a dose-dependent manner. Leaf discs treated with increasing doses (0.05, 0.5, 1 and 5 mg/mL) of the extract also showed a high percentage of repellency (94.12%) while treated eggs with these increasing doses showed a remarkable increase in the eggs&rsquo; mortality 7 days after treatment, i.e., 72.00% at 5 mg/mL. We confirmed the presence of secondary metabolites and showed an abundance of phenolic compounds, flavonoids, flavonols and tannins with different concentrations.</p>
