Abstract
The present investigation revealed that Bihar hairy caterpillar was first recorded during 32nd standard week (1.92 larvae/plant) which reached to its maximum during 41st standard week (11.93 larvae/plant) and there after gradually decreased up to 1.33 larvae/plant during 44th standard week.
The maximum temperature showed non-significant positive correlation, minimum temperature and relative humidity showed non-significant negative correlation while rain fall showed significant negative correlation with the population buildup of Bihar hairy caterpillar.
