Abstract

The present study make known that intraguild and interguild antagonism have a number of baneful sound effects in moribund the major pest density in rice field. Random quadrate sampling was performed at the peak season (October 2016-December 2016 and October 2017-December 2017) for two successive kharif crop year (2016-2017) in the insecticide unprocessed regions of rice field for surveillance and assortment of samples. Agriocnemis pygmaea (Rambur) is the leading species out of all odonata samples. Three distinguished spider guilds were observed namely, orb-weaver, space-weber and hunting spider. Orb-weavers, Tetragnatha mandibulata Walck are especially copious. Most prevalency (21.78%) of Lycosa pseudoannulata Boes was observed. This was followed by Atypena formosana Oi (16.33%) and Argiope catenulata Dole (14.56%) in descending order. Quite a lot of predators are also usually found like, Coccinella septempuntata, Menochilus sexmaculata and Micrapsis discolor etc. Conclusion: Fortification of omnivore’s results due to affluence of predator population in the rice field as bio-control agents.
