In stored crops, Sitophilus oryzae (rice weevil) can cause damage of up to 80%, depending on the circumstances of storage. A vast variety of grains and seeds, including sorghum, wheat, corn, oats, rye, barley, rice, and beans, are all highly palatable to the bug. The most practical and effective technique to control insect pests in stored food products is to use synthetic insecticides. These substances do, however, have adverse effects on the ecosystem. It has been established that plants contain important compounds that are poisonous to insects. Because they are renewable, do not persist in the environment, and are generally safe for use by humans, nontarget creatures, and natural enemies, botanicals are the preferred method of controlling pests and diseases. A lot of research has been done to determine the efficacy of plant extracts in management of rice weevil. However, the information is scattered in different publishes articles. This paper provides a review on insecticidal activity of plant extracts against Sitophilus oryzae. From the results, the most studied plant species belong to the Lamiaceae family (20) followed by Asteraceae (16), Fabaceae (9), Labiatae (9), Rutaceae (9), Myrtaceae (7) and Zingiberaceae (6). The efficacy of plant extracts against the insects depend on the type of plant, extract concentration, growth conditions, exposure duration, and plant part used. The study's findings confirm that certain plant extracts are highly poisonous, repellant, antifeedant, and have the ability to suppress growth and oviposition in Sitophilus oryzae (L.) and may offer an alternate method of preventing weevil damage to stored crops. However, very little is known about plant-derived insecticidal chemicals against the weevil. Further study to find such insecticidal ingredients and formulations is recommended.
