Abstract
Sweet potato, Ipomoea batatas is one of the important root vegetables grown throughout the globe. The production of crop is hindered as it is grown in low input conditions which in turn accounts for occurrence of the insects. The sweet potato weevil (SPW), Cylas formicarius (Fabricius) is one of the major responsible for the huge loss in healthy tuber production. The economic loss not solely because of the yield loss caused by feeding of larvae and adult weevils, but also as a result of feeding accompanied by excess production of terpenoid production, associated off-odour and bitter taste. IPM strategy can be adopted for the better management of the weevils.
