The present studies were conducted at Research Farm, College of Agriculture, Gwalior during kharif season of 2018-19. The activity of aphid, jassid and whitefly started from 34^th SMW and continued till the harvest of the crop with its peak population (22.3, 4.2 and 9.0 insects/3compound leaves/plant) in 38^th, 39^th and 39^th SMW, respectively. The activity of coreid bug and flea beetle was started from 37^th SMW with its peak population (2.9 and 3.2 insects/plant) in 39^th and 40^th SMW. The incidence of Coccinellid beetle was started from 35^th SMW till the harvest of the crop with its peak abundance (1.9 beetles/plant) in 41^th SMW. Correlation studies indicated population of aphid, jassid, whitefly, coreid bug, flea beetle and Coccinella beetle on black gram significantly positive correlated with maximum temperature and evaporation. The aphid and whitefly population positively correlated with minimum temperature. There was no relationship between the observed insect fauna on black gram with humidity and rainfall.
