Shallot Spodoptera army worm (178) Print Fact Sheet


Common Name

Common cutworm, beet armyworm. Note that the species on onion has not been identified in Pacific islands where damage to shallots has been seen. In this fact sheet, it is assumed to be Spodoptera exigua. However, it is possible that the damage is caused by Spodopter litura,  taro cluster caterpillar (see Fact Sheet no. 31).

Scientific Name

Spodoptera spp. The common species on onion in other parts of the world is Spodoptera exigua (common or beet armyworm); however, this has not been identified in Pacific island countries, and the species attacking onion is likely to be Spodoptera litura.
