Abstract This study was conducted during August to November in 2016 and 2017 to record the insect pests that attack black gram grown in a sequential farming at rice nursery located in the village Dehar Kuriha under Hajo revenue circle of Assam. Thirteen insect species under Lepidoptera, Coleoptera, Orthoptera and Hemiptera were identified, with more than 50% belonging to the Hemiptera. Incidence and damage of Omiodes indicata, Maruca testulalis and Apion clavipes were found high. The highest mean density (227.2/plot and 231.11/plot) and relative density (21.8% and 22.2%) was found in Apion clavipes. Most of the insect pests made their appearance in the 39th standard week of the crop growth.
