An experiment was conducted during Kharif, 2019-2020 at Agricultural Research Station, Darsi, Prakasam (Andhra Pradesh) to observe the “Succession of insect pest complex and their natural enemies in pigeon pea [Cajanus Cajan (L) Millsp.]”. Result revealed that 10 species of insects (7 pest and 3 natural enemies) were observed in pigeon pea i.e. Jassids Empoasca fabae Harris, Cow bug Otinotus oneratus W., Pod bug Clavigralla gibbosa Spinola, Riptortus sp., Green stink bug Nezara viridula Linn, Pod fly Melanagromyza obtusa (Malloch), Leaf Webber Grapholita critica (Meyr), Blister beetle, Zonabris sp., Gram pod borer Helicoverpa armigera (Hub.), plume moth Exelastis atomosa (W.), Spider, Hogna lenta, Lady bird beetle, Coccinella septempunctata (Linn.) and Green lace wing, Chrysoperla sp. Incidence of jassids was observed from 32nd (vegetative stage) to 52nd SMW (flowering stage) of the crop. Similarly, the incidence of leaf webber was observed from 32^nd to 48^th SMW. Insect pests feeding on floral parts viz., blister beetle, gram pod borer and bean pod borer was noticed during 45th to 2nd week of January. Pod fly incidence was recorded during pod filling stage of the crop i.e. from 50^th to 3^rd SMW. Population of natural enemies lady bird beetle and green lace wing was observed from vegetative stage to pod formation stage. Whereas, population of spiders observed from 32^nd to 3^rd SMW.
