Online published on 18 April, 2020. Abstract Some edible and non edible oils were evaluated against the rice weevil Sitophilus oryzae (L.) infesting paddy during 2018–19 at the Biological control Laboratory and P.G. Research Laboratory, Department of Agricultural Entomology, N. M. College of Agriculture, Navsari Agricultural University, Navsari. The results indicate that significantly maximum mortality (79.58%) with minimum seed damage (2.56%) and weight loss (1.58%) was observed in the seeds treated with mustard oil @1% followed by castor oil (4.22%, 2.88%, 70%, respectively); and sesame oil at 1% was the least effective, resulting in maximum seed damage (9.93%), weight loss (6.40%) and the least mortality (52.09%).
