Abstract
The present survey was conducted during Kharif 2011 and Kharif 2012 in Varanasi district of Uttar Pradesh, India. Twenty six insect-pests and natural enemies of crop plants, belonging to 9 different orders (including Acarina group) were recorded in the rice (Oryza sativa L.) agroecosystem. The maximum percentage of insect-pests and natural enemies were recorded in the order Coleoptera (23.10%), followed by Lepidoptera (15.40%), Homoptera, Isoptera and Thysanoptera. Insect pests viz., yellow stem borer, green leaf hopper and gundhi bug were highest in proportion, whereas rest others were found to be medium or low in proportion. Among natural enemies and predators, rove beetles, tiger beetles, carabid beetles, damsel flies and dragon flies were recorded from the rice agro-ecosystem.Fkh
