Repellent and Antifeedant Effects of Essential Oils and their Compounds Against Rice Weevil <i>Sitophilus oryzae</i> (l): An Analysis of Ongoing Research

Abstract

This systematic review evaluates the repellent and antifeedant effects of essential oils (EOs) against the insect pest Sitophilus oryzae L. From an initial search of 2,543 articles, 49 studies met the inclusion criteria. The review highlights that EOs from 67 plant species across 18 families were tested, with 55 exhibiting repellent effects and 12 showing antifeedant properties. Notably, 8 species demonstrated both effects. The most frequently tested families included Lamiaceae, Apiaceae, Anacardiaceae, and Myrtaceae. Key findings indicate that EOs can significantly deter S. oryzae, with specific compounds like linalool and α-pinene being particularly effective. The results underscore the potential of EOs as bio-insecticides, although field studies are needed for practical applications in agriculture.
