Abstract

Field experiment was carried out to estimate the yield losses in pigeon pea crop due to insect pests during kharif 2018-19, 2019-20 and 2020-21 at College of Agriculture, Navsari Agricultural University, Bharuch (Gujarat). Results revealed that avoidable yield loss due to insect pests in pigeon pea was recorded up to 38.48% when no plant protection measures are taken. Amongst different insect pests, the maximum damage was recorded due to pod borer, Helicoverpa armigera (34.90%) followed by pod sucking bugs, Clavigralla gibbosa (29.75%) and pod fly, Melanogromyza obtusa (23.64%). Pod damage due to spotted pod borer, Maruca vitrata and tur plume moth, Exelastis atomosa was recorded up to 14.09% and 5.60%, respectively.
