Rice insect pests are major constraint in rice production. The insect pests of rice infest all parts of the plant at all growth stages and transmit few viral diseases of rice. Rice is grown mostly under Indo-Gangetic plains zone of India, which is widely distributed in Uttar Pradesh. This zone is mostly a warm humid environment conductive to the survival and proliferation of arthropods biodiversity. A study was undertaken to surveillance of population dynamics of insect pest complex under rice field ecosystem of Eastern Uttar Pradesh, India for two consecutive years, 2014 and 2015 in rainy season (Kharif). The surveillance was conducted in 03 administrative divisions namely, Gorakhpur, Basti and Azamgarh. There were 38 insect pest species observed under 03 rice growth stages of seedling, transplanting and flowering. The test of significance was used analysis of variance in randomized block design (RBD). Of the total observed test of significance under the population of rice insect pest

Population dynamics, Rice insect pest complex, Eastern Uttar Pradesh, India.

The significant variation among damaging groups and growth stages of rice were followed the natural phenomenon of variation, while non-significant variation among administrative divisions were represented the similar ecosystem of confined area of study. The significant variation among damaging groups and growth stages of rice under observed administrative divisions reflects the particular management strategy for particular source of significant variation, while the non-significant variation among administrative divisions solely reflects the universal management strategy for all sources of variation. Similar findings have been reported by Chakraborty and Deb (2012); Gangwar et al., (2015); Saini et al., (2015); Parasappa et al., (2017); Dwivedi (2018).
