Reproductive Rate; Age Specific Life Table Study; Stage-Specific Life Table Study; Milled Rice Grains.

An experiment was conducted on the study of life table statistics of rice weevil, Sitophilus oryzae in milled rice grains in the laboratory of Department of Entomology of College of Agriculture under Odisha University of agriculture and technology, Bhubaneswar in coastal climatic condition of Odisha indicated that the stage-specific life table study revealed that the sex ratio was 0.94: 1.00 with a generation survival rate of 0.569. The age specific (female fecundity) life table study revealed the net reproductive rate (R0) of 16.35 with the mean length of generation (T) of 36.65 days and the intrinsic rate of natural increase (rm) of 0.076.
