Pulsesare the major protein supplements in human nutrition. Pulse crops also called grain legumes, have been valued as food, fodder and feed in the Indian agriculture centuries, but they have rather a very low profile compared to cereals. The studies conducted on population dynamics of Marucavitrata on pigeonpea revealed that the incidence of Maruca vitrata was noticed from 51ststandard week (1.75 No’s) with peak incidence in 2nd standard week (14.54 No’s) and it was reduced to 1.01 No’s on 6th standard week. All the weather variables (maximum and minimum temperature, morning and evening relative humidity and rainfall) together accounted for 82.1%variation in larval population which was significan. Only minimum temperature showed significant influence independently on variation in larval population.
