Abstract:
Investigations were carried out to study the “Seasonal incidence and correlation fall armyworm of maize at the Department of Agricultural Entomology, College of Agriculture, Parbhani during Rabi 2018-19. The experiment is carried out in unprotected condition with net plot size 10 x 10 m2 in non-replicated and divided in four quadrants. Five plants or 1 m row was randomly selected from each quadrant for recording pest wise observations. All recommended agronomical practices were followed from time to time to raise the crop successfully to have full benefits. The first appearance of fall armyworm was noticed in 1st SMW (16 larvae/ 10 plant) thereafter it was increased gradually and reached its peak (22 larva/10 plant) in 6th SMW. Correlation between weather parameters and fall armyworm of maize showed that the larval population of fall armyworm showed non-significant positive correlation with maximum temperature (r=0.451) and minimum temperature (r=0.374). While morning relative humidity (r=-0.284) and evening relative humidity (r =-0.246) showed non-significant negative correlation with larval population of fall armyworm.
