| dc.description.abstract | "Victory-1, the newly evolved hybrid mulberry was evaluated for rearing performance of the Mulberry silkworm, Bombyx inori (L) (NBjD2) by adopting different feeding methods and frequencies at Department of Sericulture, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka, during 1999-2001. V-1 recorded significantly lower total larval duration, less pupal duration and lower disease incidence as compared to S.v,. Larvae reared on V-1 consumed significantly more food than S.v,. V-1 was superior to S36 with respect to weight of 30 worms just before settling for third moult, maximum fifth instar ten larval weight, cocoon weight, shell weight, shell percentage, pupal weight, moth emergence, fecundity, hatching percentage, single cocoon bave length, silk filament weight, cocoon yield by number, cocoon yield/kg, denier, renditta and ERR The cost benefit ratio was higher with V-1 than S c >36 Among the feeding methods shoot rearing effected significantly lower total larval duration, lesser pupal duration and lower disease incidence as compared to shelf rearing Shoot rearing method induced more feeding than shelf rearing. Shoot rearing recorded significantly higher weight of 30 worms just before settling for third moult, maximum fifth instar ten larval weight, cocoon characters, pupal weight, grainage parameters, silk characters, ERR and cocoon yield. The cost benefit ratio was higher in shoot rearing method than shelf rearing method. Of the various feeding frequencies four feeds recorded significantly lower total larval duration, lesser pupal duration and lower disease incidence than single feed per day. Significantly higher leaf consumption was recorded in four feeds while one feed recorded lesser leaf consumption: Four feed frequency effected significantly highest weight of 30 worms just before settling for third moult, maximum fifth instar ten larval weight, cocoon characters, pupal weight, grainage parameters, silk characters, ERR and cocoon yield. However, based on the results of the present investigation irrespective of the varieties used three feed frequency is equally economical to that of four feeds particularly in areas of labour shortage." | en_US |
