Abstract
Fall armyworm, Spodoptera frugiperda is an invasive alien pest that primarily targets maize crops. The effect of meteorological parameters on the incidence of S. frugiperda larva on fodder maize was investigated in the IGFRI, Dharwad, Karnataka, India, during Kharif, 2021-2022. Field experiment was conducted to know the pest status in Dharwad region. The results revealed that the larval counts and %infestation were 0.85 to 2.25 larvae/plant and 10 to 46.05%, respectively. Parasitization by two larval parasitoids viz., Campoletis chlorideae (Hymenoptera: Ichneumonidae) and Exorista xanthaspis (Diptera: Tachinidae) and predators like Chelomenus sexmaculata , Harmonia octomaculata, Coccinella transversalis, Illeas cincta, earwig and spiders were also observed.
