The egg period in this pest species was 4.0 to 7.0 days with an average of 5.27 days. The hatching percentage was 67.33% at 32.43 ± 0.29°C. The larval period varied from 52 to 78 days with an average of 61.16 days at 27.71 ± 0.34°C. Most of the larvae moulted seven times, but some moulted eight times. The pre-pupal period was invariably only one day. The pupal period varied from 3 to 5 days with an average of 4.16 days. The egg laying capacity of the beetle varied from 3 to 13 with an average of 9.6 eggs within 24 hr. Both the larvae and the adults caused damage to the rice grain near its germ portion and rendered it useless for human consumption. Rice flour along with the frass was found to be collected at the bottom of the container in the laboratory. At times few grains were found to be adhered each other in the salivary secretion of the insect.enAGRICULTURAL ENTOMOLOGY, AGRICULTUREA STUDYThesis
