Author Name Bhumika Solanki, A.M. Bharadiya, A.M. Parmar and T.S. Bhuva Abstract The activity of leaf eating caterpillar, S. litura was commenced from 30th SMW i.e. third week of July (1.05 larva per plant) which gradually increased and attained a peak of 4.10 larva per plant during 36th SMW coinciding with the first week of September. Thereafter, S. litura population started declining and reached a minimum during the 42nd SMW (0.98 larva per plant) coinciding with the third week of October. Finally, the pest population disappeared from the field after the fourth week of October. Correlation studies between meteorological parameters and the S. litura population showed significant negative correlation with maximum temperature (r= -0.522*) and positive significant correlation with minimum temperature (r= 0.527*), relative humidity (r= 0.617*) and rain fall (r= 0.555*). Whereas, non-significant negative correlation with bright sunshine hours (r= -0.475) and wind speed (r= -0.159).
