Abstract
Three artificial hatching methods ; hydrochloric acid under room temperature, hot hydrochloric acid and hot water were used to terminate the diapause of diapausing eggs of three silkworm races of B. mori L. for late Autumn rearing season. Egg performance as post treatment period, one day hatching rate, practical hatching rate, general hatching rate, rate of bluish eggs , rate of non bluish eggs and rate of dead eggs were recorded .
           Also, the economical characters as weight of mature larvae, total larval duration, larval mortality percentage, cocoon, cocoon shell and pupal weights, cocoon shell ratio, cocooning and pupation percentages were also registered . Results show that hot acid treatment was inferior than the other two methods for most of the parameters under study .
