| Characteristic Damage: | |
|
Larval feeding causes characteristic tunnels/ irregular mining patterns that enlarge as the larvae mature. |
|
Mining reduces the photosynthetic capacity of the leaves.. |
|
Severe mining causes premature dropping of leaves. |
| Management and Control: | |
|
Monitor the area regularly. |
|
Use yellow sticky traps to reduce adult leaf miner. |
|
Remove and dispose properly heavily infested leaves. |
|
Cultivate the soil by plowing and harrowing and use plastic mulch to minimize pupation in the soil. |
|
Use of natural enemies like parasitic wasps from the families Braconidae, Eulophidae, and Pteromalidae can keep leaf miner population below economic threshold level. |
|
Apply insecticides like buprofesin, profenofos, imidacloprid, thiamethoxam and cyromazine when necessary. |
