| Common Name: | |

American serpentine leafminer |
|
Serpentine leaf miner |

|
Gram pod borer |
| Damaging Stage: | |
|
Larvae
|
| Crops Afected: | |
|
Cucurbits, solanaceous, legumes, brassicas, onion
|
| Characteristics 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. |
| Control and Management: | |
|
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 (e.g. Applaud®), profenofos (e.g. Selecron®) and cyromazine (e.g. Trigard®) when necessary. |
