Abstract:
The incidence of brown plant hopper (Nirparvata lugens (Stal.) was started from 33^rd MW i.e. second week of August with its peak during 41^st MW i.e. second week of October. The continuous increase in population of brown plant hopper was recorded since 33^rd MW to 41^st MW. Incidence of brown plant hopper showed significant negative correlation with rainfall (r = -0.490), morning relative humidity (r = -0.619) and positive correlation with maximum temperature. The incidence of stem borer was commencing during 34^th MW and increased gradually 37^th MW. The incidence of leaf folder was initiated in 35^th MW and reached to its peak in 37^th MW. The correlation analysis regarding leaf folder and stem borer revealed a significant positive correlation with maximum temperature and significant negative correlation with evening humidity, respectively.
