Abstract: This paper reports the natural enemies of insects’ pest in pigeonpea [Cajanus cajan] in Raipur, Chhattisgarh during Kharif season 2013-2014. The present study was conducted at the Research cum Instructional Farm, IGKV, Raipur, Chhattisgarh during Kharif season 2013-2014. Recent research investigating the complex interactions among pigeonpea, its key pests, and their natural enemies was reviewed. These relationships have implications for the pest status of individual species and possible control strategies. Natural enemies occurred in an overlapping manner and one or other was continuously observed at different stages of growth. The natural enemies of insects pest in pigeonpea crop were first observed during the last week of July i.e. 31^th SMW with 0.20 natural enemies per plant when the crop was at two leaf stage. The maximum number of natural enemies associated and their peak activity was recorded during the periods of flowering and pod maturity. The natural enemies recorded from seedling to podding are Hymenopteran wasps (Apanteles sp. and Vespa orientalis), ladybird beetles (Coccinella septempunctata and Cheilomenes sexmaculata), mirid bug (Cyrtorrhinus lividipennis), praying mantis (Mantis religiosa), dragonfly (Crocothemis servilia), and green lacewings (Chrysoperla carnea). Among spiders (Neosconatheisi sp. Oxyopes sp. Araneus sp. and Clubiona sp.) were observed.
