A field experiment was conducted at instructional farm, Rajasthan College ofAgriculture, Udaipur during kharif2015 and 2016 to estimate the losses caused by major insect-pests infesting greengram. The infestation of insect pests in greengram significantly affected plant height, pods per plant, seeds per pod, seed yield per plant and seed yield per plot. The loss estimation in greengram due to infestation of insect pests taking into account different yield attributing traits indicated that mean plant height under treated condition was 1.14 and 1.12 times more than that in untreated condition; likewise, the mean numbers of pods were 1.12 & 1.18 times more than that under untreated condition. The mean seed per pod under treated condition was 1.19 & 1.20 times more than under untreated condition. Mean yield per plant (3.66 & 3.74 g/plant) and mean yield per plot (1.46 & 1.49 kg/plot) was significantly more in treated crop. The overall mean loss worked out to be 22.39 and 26.80 per cent due to the insect-pest infestation during 2015 and 2016, respectively.
