A STUDY ON THE GUILD INTERACTION OF PREDATOR NATURAL ENEMIES IN A RICE FIELDGobinda Chandra Roy, Kaushik Chakraborty and Siddharthasankar Banerjee
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. Study design: 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. Results: 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.
