The 'Soorai' disease of paddy is caused by a mealy bug-Ripersia oryzae, Green,-belonging to family Coccidae, order Rhynchota. The insects suck the plant sap and, as a result of their attack, the affected plants get stunted in growth. In severe cases of infestation the earheads get smothered and either fail to emerge from the sheath or when emerged do not produce healthy grains. The nfestation is seen to occur in patches in the field.
