Summary, etc. <p>Recent studies regarding the harmful effects of synthetic larvicides initiated the need to investigate for unconventional measures that are environmentally-safe and target-specific against <em>Aedes aegypti</em> larvae. Thus, the main objectives of the study are to evaluate the ovicidal, larvicidal and adulticidal toxicity of the hexane extract of <em>Citrus grandis </em>peels against dengue vector, <em>A. aegypti. </em>Results revealed that the hexane extract of <em>C. grandis </em>peel from Davao exhibited the highest lethal concentration against 3<sup>rd</sup> and 4<sup>th</sup> instars larvae with an LC<sub>50</sub> and LC<sub>90</sub> of 1.11 mg/L and 3.32 mg/L, respectively. Moreover, the knockdown effect of the hexane extract of <em>C. grandis </em>peels on adult female <em>A. aegypti</em> produced 50% knockdown within 11.50 minutes and 90% knockdown within 28.79 minutes. The test mosquitoes’ mortality was 100% after 24 hours. Lastly, the ovicidal activity of the hexane extract against the eggs of <em>A. aegypti </em>exhibited an LC<sub>50</sub> of 13.84 mg/L and LC<sub>90 </sub>of 25.30 mg/L. The remarkable effects exhibited by <em>C. grandis</em> peels indicate its great potential to be a more sustainable and environmentally-safe plant-based control for the proliferation of the dengue vector, <em>A. aegypti.</em></p>
