Abstract:
The incidence of brown plant hopper (Nirparvata lugens (Stal.) was started from 33rd MW i.e. second week of August with its peak during 41st MW i.e. second week of October. The continuous increase in population of brown plant hopper was recorded since 33rd MW to 41st 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 34th MW and increased gradually 37th MW. The incidence of leaf folder was initiated in 35th MW and reached to its peak in 37th 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.
