Jalna under the guidance of college of agriculture Badnapur during kharif 2021, to know the seasonal incidence of fall armyworm, Spodoptera frugiperda egg masses of fall armyworm 28^th SMW 3^th week of July with the mean population of 0.10 larvae/plant and 0.30 egg masses/plant respectively. The peak populations were observed in the 2^nd week of August (32^nd SMW) with mean population of 3.20 larvae/plant and egg masses of fall armyworm were 0.80 egg masses/plant. The correlation between fall armyworm Spodoptera frugiperda with weather parameters during kahrif 2021 results indicate that the population demonstrated a non-significant negative correlation with maximum temperature, minimum temperature, morning humidity, evening humidity and rainfall. The correlation between egg masses of FAW in relation to weather parameters indicate that the population demonstrated a non-significant positive correlation with morning, evening humidity and rainfall. The natural enemies like LBB, predatory spider and predatory bug were also recorded during a season with ranged from 1.2 to 2.2 per plant, 0.2 to 2.2 per plant and 0.4 to 0.85 per plant respectively.
