Larvae |
| Crops Affected: | |
|
Cucurbits, solanaceous, legumes, brassicas, cotton, tobacco, onion |
| Characteristic Damage: | |
|
Newly hatched larvae attack their hosts in cluster and feed gregariously by scraping the leaf surface. |
|
Larvae move and feed on the other leaves making large irregular holes and may leave only the veins. |
|
High infestation results to severe defoliation. |
| Management and Control: | |
|
Monitor the area regularly. |
|
Hand pick the larvae to reduce the population. |
|
Remove weeds and volunteer plants that may serve as alternate hosts. |
|
Cultivate the soil by plowing and harrowing and use plastic mulch to minimize pupation in the soil. |
|
Plant trap crops like sunflower, taro or castor plants around the area. |
|
Use of pathogens like the nuclear polyhedrosis virus and entomopathogenic fungi Aspergillus flavus, Beauveria bassiana and Metarhizium anisopliae to reduce cutworm population. |
|
Apply botanical insecticide like neem extract. |
|
Apply lambda-Cyhalothrin (BidaⓇ, KarateⓇ, DescarteⓇ), fipronil (e.g. Ascend®, Flipper®), Bacillus thuringiensis subspecies aizawai (Bta) (e.g. Xentari®, Aztron), acephate (e.g. Acetam®, BlackhawkⓇ), fenitrothion (Sumithion 50Ⓡ), deltamethrin (e.g. Decis®, DecideⓇ, ScoutⓇ, Agro DeltametrinⓇ). |
