  • This experiment was carried out to develop an artificial diet and a mass rearing system, which is essentIal in the pheromone research for Ostrmia furnacalis. Component deletion and addit.ion methods were applied t.o define the nut.ritional Importance of some components, especially yeast, Wesson's salt mixture and vitamin complex. Secondly we have developed a proper rearmg syst.em for O. furnacalis. and also tried to find out the factors affecting rapid sclerotization (dark-canning) of pupae. AddItion of yeast raIsed the pupal weight. and pupation rate. However Wesson's salt mixture got the female pupae lighter. Vitamin complex as a substitue for yeast showed a good survivahty in an early larval stage buL pupal weight was lower than that of the individuals reared on the yeast dIet. Also corrugated cardboard was found to be very good for pupation. And the rate of dark~tannmg in pupae was higher as the period of larval development was shorter.
