An experiment was conducted at Students Instructional Farm, Acharya Narendra deva University of agriculture and technology Kumarganj, Ayodhya (U.P.). during Kharif season 2021. The incidence that, the yellow stem borer, leaf folder, green leaf hopper, BPH and gundhi bug were recorded. The highest dead heart per cent of yellow stem borer was recorded on rice at 36th SMW (12.97 per hill) and white ear per cent (7.41 per hill) in 44th SMW, leaf folder 41st and 32nd SMW (6.75 & 0.10 per hill), green leaf hopper 43th and 32nd SMW (3.25 & 0.20 nos./hill), BPH 44th and 34th SMW (9.84 & 0.15 nos./hill) and gundhi bug 45th and 40th SMW (1.37 & 0.20 per hill).
Yellow stem borer (dead heart) was showed non-significant positive correlation with rainfall, minimum, maximum temperature and sun shine however, relative humidity showed significant positive correlation with dead heart. White ear showed that non-significant negative correlation with rainfall while, minimum, maximum temperature and relative humidity significant negative correlation however, sun shine showed non- significantly positive correlation with white ear. Leaf folder incidence showed non- significant positive correlation with rainfall and relative humidity, maximum and minimum temperature showed non-significant negative correlation, however sun shine showed significant positive correlation. Relative humidity and rainfall exhibited non-significant negative correlations with the incidence of green leaf hopper, although substantial positive correlations with sun shine and minimum and maximum temperatures were observed. Minimum and maximum temperatures, relative humidity, and rainfall all exhibited non-significant negative correlations with the population of BPH; however, sunshiny days revealed a substantial positive link. The incidence of gundhi bug, showed significant negative correlation with minimum, maximum temperature and relative humidity correlation while rainfall and sun shine showed non-significant negative correlation and non-significant positive correlation respectively.
