Abstract
Rice is the most important staple food for more than half population of the India and world. 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. Insect pests are major constraints in rice production. Bioagents have been playing potential role in ecofriendly insect pest management. A study was undertaken to surveillance of population dynamics of bioagent 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 41 bioagent 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 signi

Conclusion
The significant variation among most bioagent 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 most bioagent 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 Ooi and Shepard (1994); Bhattacharyya et al., (2006); Gangurde et al., (2007); Fahad et al., (2015); Chakraborty et al., (2016); Heinrichs and Muniappan, (2017); Parasappa et al., (2017); Krishnaiah and Varma (2018).
