The field experiment was conducted at main experimental station of Narendra Deva University of Agriculture and Technology, Kumarganj Faizabad (.) during the season kharif, 2015 to know the occurrence and abundance of insect-pests of paddy on rice crop was monitored on rice variety Pusa Basmati. This investigation revealed that pest activity commenced from 31th Standard meteorological week (SMW) and continued upto 49th SMW. The peek population of rice hispa was found in the 31st SMW, green leaf hopper was found in the 37th SMW, grass hopper and yellow stem borer was found in the 39th SMW and leaf folder was found in the 41st SMW. Population of yellow stem borer (YSB) was positively correlated with maximum temperature. The population of rice hispa had non-significant and positive correlation with rainfall and maximum temperature. The population of green leaf hopper showed positive and significant correlation with minimum and maximum temperature, relative humidity and rainfall. The population of rice leaf folder showed negative correlations with minimum and maximum temperature and relative humidity. | 2019 8 6 551-555 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 06 2019 Journal homepage http Original Research Article https Incidence of Insect-Pests on Rice in Faizabad Yadav Abhinandan1 .
