Rice covers around 16.78960 lakh hectare areas out of total cultivable area of 38.00 lakh hectares with net sown area of 25.75 lakh hectares, the production and productivity are 4988.065 thousand tone and 2971 kg per hectare respectively in the state of Jharkhand (Anonymous, 2018). The pest spectrum of the crop varies in time and space according to variations taking place in the agro- ecologies that is regulated by changes in the biotic and an abiotic factor as well as ever changing farming practices. The pest International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Special Issue-7 pp. 3382-3388 Journal homepage: http://www.ijcmas.com Rice is the major staple food in Asian country as well as India & Jharkhand. Rice production decrease, among various reasons of low production of rice, insect pest complex are one of the major factors for lowering down the yield. Pest scenario of a rice crop varies from region to region, due to variation in the agro-climatic condition of that region. We have conducted pest survey and surveillance for visualization of real pest problem of an area and formulating an IPM model. The result revealed that as many as two dozen insect pests but only seventeen are more prominent was to attack rice crop in the field condition. We found nine insect (Yellow stem borer, Gall midge, Leaf folder, Earhead / gundhi bug, Green leafhopper, BPH, Rice hispa, Termite, Grass hoppers) prevalence in almost the whole state were to attack rice crop in the field condition as low to severe form. And out of seventeen six (Yellow stem borer, Gall midge, Leaf folder, Earhead / gundhi bug, BPH, and Termite) are major pest status in 24 districts in Jharkhand, rests seven (Green leafhopper, Rice hispa, Grass hoppers, Rice Mealy Bug, Root/white Grubs, Whorl maggot and Thrips) are minor and four (Case Warm, Swarming Caterpillar, Hairy Caterpillar and Cut Warm) are sporadic pest status in Jharkhand state. Depending upon topography, land is broadly classified into six groups by state. In Don I & Don II, major pest are found YSB, RH, CW, RLF, GLH, RGB, BPH, RGH, & GM and Don III & Tanr III is medium land in this region major problem of pest are YSB, RH, RLF, GLH, RGB, RMB, BPH, RGH, SwC, BhC, Thrips, and GM. Tanr I & Tanr II pure upland condition in this area major problem of Termite, YSB, RH & WG. Keywords Insect pest, rice ecosystem, staple food
