The ways by which the insects attack the crop plants are:
- The chewing insects destroy all sorts of crop plants. They cut the root, stem and leaf of the crop plants by the help of their chewing mouth parts.
- Sucking insects suck the cell sap from various parts of the plant. They make fine punctures in the skin of plants with their needle - like, hollow beaks and suck the sap.
- The internal feeders live inside the plant parts. They make holes in the developing grains.
