              Damage and Economic Implications

              • The damage of the rice weevil is more than the granary or wheat weevil because it has the ability to fly.
              • It infests grain (rice, wheat, barley, and corn) in the field before harvesting.
              • It multiplies rapidly in the summer.
              • The larva and the adult insect feed on the stored grains, destroying them and making them vulnerable to other insects.
