Abstract

Seasonal activity of Spodoptera frugiperda (J. E. Smith) in maize agroecosystem of South India.

Abstract

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), was first detected in India in 2018 and seriously threatened the maize crop. In South India, we studied the population dynamics of FAW moths and the dam-age caused by the larvae in maize fields from 2019 to 2020. In the kharif season, the highest male moth catches occurred in July while in rabi season, the high-est catches occurred in November. It was found that the early whorl stage (EV-V6) of maize crop was susceptible to FAW due to its high larval load, whereas the late whorl stage (V7-VT) of the crop showed greater leaf damage in both years.
