Black gram is the member of Vigna crop group and also known as urd bean it is grown in Kharif season in the Indian subcontinent. It is the fourth most important pulse crop grown in India. Black gram crop is attacked by a number of insect pests from sowing to harvest in the field. The present research aimed to study on insect pests spotted pod borer, Maruca vitrata (Geyer) and gram pod borer, Helicoverpa armigera (Hubner) are serious insect-pests of black gram causing seed and pod damage. The research trials were conducted during Kharif, 2024 at Department of Entomology, Organic Research Farm Kargua Ji, Institute of Agricultural Sciences Bundelkhand University, Jhansi (U.P.) to observe the Seasonal incidence of pod borers complex (M. vitrata and H. armigera) in black gram with variety ‘Azad’. The study on the seasonal incidence of pod borers viz., M. vitrata and H. armigera start from 33^th to 43^th standard meteorological week and both the larvae attain their peak in 40^th and 42^th standard meteorological week. Bacillus thuringenesis var-Kurstaki is the best treatment as it exhibits lowest leaves and pod infestation, highest yield and highest benefit cost ratio were recorded. It is advisable to sown the crop in the early of June and when insect population reached at ETL, application of Bacillus thuringenesis give better result.
