Novel insecticides with unique mode of action, were treated to mulberry leaves by foliar spray, later the leaves were fed to the silkworms which were reared on 10, 20, 30 and 40 Days After Spraying (DAS) of insecticides to mulberry plants. Flonicamid 50 WG @ 0.3 g/l recorded 100 per cent silkworm mortality and zero per cent mortality was recorded in all the other treatments. The prolongation of larval periods were noticed when the silkworms were fed with insecticide treated leaves at third, fourth and fifth instars. The silkworms recorded lowest larval weight in the treatment flonicamid @ 0.3 g/l and highest larval weight was recorded in dinotefuran 20 SG @ 0.25 g/l and dichlorvos 76 EC @ 2.63 ml/ l at 10, 20 30, 40 DAS. Effective Rate of Rearing of 100 per cent was recorded in silkworms fed on mulberry leaves from treatments pymetrozine 50 WG @ 0.3 g/l at 10 DAS, azadirachtin 1% @ 2 ml/l and dichlorvos 76 EC @ 2.63 ml/l at 30 DAS.
