Nature of Damage of Cut worm
- The common cutworm is a problem generally on upland rice only because it needs dry soil for pupation and for completion of its life cycle.
- Lowland rice usually suffers heavy damage from larvae migrating from adjacent grassy areas.
- They are most serious during the seedling stage of rice when they sever the seedlings at the base.
- When abundant during late crop growth, they may severely defoliate the rice crop.
- The climbing cut worms cause more damage to panicles.
- Their outbreaks are usually characterized by the sudden appearance of larvae in immense numbers; severe losses are inflicted even before the worms are detected.
- Cutworms can defoliate rice fields, generally in patches, from early vegetative growth to harvest.
