Field experiments were carried out to evaluate the yield losses caused by lepidopteran pests on castor during kharif-2018-19. Semilooper, tobacco caterpillar, capsule borer were recorded as major pests. The results revealed that the treatment covered with nylon net recorded zero larval population and zero per cent capsule damage followed by the treatment protected up to 120 days (0.88 larvae / plant and 8.80 %), protected up to 90 days (1.48 larvae / plant and 14.33 %), protected up to 60 days (2.21 larvae / plant and 19.77 %) and protected up to 30 days (3.60 larvae / plant and 29.86 %). In the Untreated check recorded highest mean larval population of 5.21 larvae / plant and 30.15 per cent capsule damage was recorded.
