ECONOMIC DAMAGE caused by Sesamia grisescense
The larval stages cause important economic damage
- Reduced cane yield
- Reduced sugar yield
- Poor quality of cane juice
- Lower recovery of sucrose at the mill
- Increased fibre
- Reduced glucose/fructose ratio
- Increased harvest costs
- Secondary damage by weevil (R. obscurus) leads to increased damage intensity with poorer ratooning ability
