| Damaging stage: | ||
|
Larvae | |
| Crops Affected: | ||
|
Cucurbits, solanaceous, legumes, brassicas, onion | |
| 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 and cyromazine when necessary. | |
