Lepidopteran pests of corn in the Philippines vis-a-vis the imminent invasion by the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera:Noctuidae): quick review and nature of damage
2019
Caasi-Lit, M.T.
A quick review of the field characteristics of lepidopteran pest of field corn already known to occur in the Philippines as well as their nature of damage is provided. This aims to provide field technicians, research entomologists, and other workers a working familiarity, especially of species closely related to the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith). Diagnostic notes and photographs of the following are provided: the Asian corn borer, Ostrinia furnacalis (Guenée) (Crambidae) and the species of Noctuidae, namely: the corn earworm Helicoverpa armigera (Hubner); true armyworm, Mythimna separata (Walker); common cutworm, S. litura (Fabricius); and the corn semi-looper, Chrysodeixis eriosoma (Doubleday). Aside from the morphological characteristics enumerated for the larvae of these species, their damage to field corn is nowhere similar to what is known in other countries for FAW. Characteristic larval features and damages to corn that differentiate each of these lepidopterous species are discussed.
