Abstract: The experiment of hatching of ephippial eggs indicated that the factors affecting hatching rate included the length of period of storage and methods of treatment in the dark response process. The hatching rate increased with the length of incubation period between 0 and 62 days, but had slight decline over 62 days The best method of treatment of eggs was perserved in -4℃ for period of 62 days Desiccation and alternative wet-dry cycles also can promote the hatching rate of ephippal eggs.Light, salinity and temperature were the main factors in the light response process. Light was the first necessary factor for the hatching of eggs. Salinity and temperature not only affected the hatching rate, but also affected the rate of development.
