Abstract: Tasar silkworm A. mylitta was evaluated with different egg laying devices at Janjgir, Chhattisgarh for better seed production of tasar grainagers. Earthen cup was recorded maximum number of laid eggs (241) and first day highest hatching (45 per cent). The second day maximum hatching (43 per cent) was recorded in paper cup and the third day highest hatching (31 per cent) was recorded in plastic box but nylon net bag was found superior in case of maximum total hatching (90 per cent) with least unlaid eggs (17.20) and highest coefficient of egg laying (93.04 per cent). The time taken for harvesting of eggs was minimum (21.33 second) in case of wax coated paper cup. Among all the devices, nylon net bag was the most cost effective and durable device for egg laying.
