Rice stand second in the world after wheat in area and production. Almost 90% of rice is grown and consumed in Asia (Anonymous, 2006). At global level, rice is grown on an area of about 155.2 million ha with production and productivity of 461 million tonnes and 4.09 tonne ha -1 respectively. India ranks first in respect of area 43.95 million ha second in production 106.54 million tonne, only after China, but the productivity of rice is very low only 2.42 tonne ha -1 . In Madhya Pradesh rice is cultivated in area of 1.93 million ha with production of 2.78 million tonne and productivity of 1.44 tonne ha -1 (Anonymous, 2014). Worldwide food plants are damaged by more than 10,000 species of insects (Dhaliwal et al., 2007). In India, average losses of paddy production due to insect pests are 25-30% (Dhaliwal and Arora, 2010) and in Madhya Pradesh about 40-100 % losses were observed (Dhamdhere, 1990). Nocturnal insects are often attracted to light sources that emit large amount of UV radiation, and devices that exploit this behavior, such as light traps for forecasting pest outbreaks, and electric insect killers, have been developed (Shimoda and Honda, 2013). International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 08 (2018) Journal homepage: http://www.ijcmas.com The present research was studied on seasonal incidence and population dynamics of major insect pest species of paddy collected in light trap by operating, Jawahar light trap (with 80 Watt mercury vapour lamp) in paddy field at Krishi Nagar experimental farm, Adhartal during kharif 2014. Result showed that all 8 species were identified as pests of paddy having regular occurrence in light trap catches like Army worm, Mythimna separata (Walker), Rice leaf folder, Cnaphalocrocis medinalis (Guenee), Rice butterfly, Melanitis leda ismene Cramer, Rice gundhi bug, Leptocorisa acuta (Thunberg), Green leaf hopper, Nephotettix virescens (Distant), Short horn grass hopper, Tetrix subulata Linnaeus, Field cricket, Euscyrtus concinnus (de Haan), and Mole cricket, Gryllotalpa orientalis Burmeister.
