Embryo isolation and egg preservation technology of eri silkworm Samia ricini (Donovan) (Lepidoptera: Saturniidae)

[摘要]  Embryo isolation and egg preservation is one of the important aspects for synchronizing the eri silkworm Samia ricini Donovan rearing activities. The experiment of embryo isolation and preservation of eri eggs revealed that the 36-40 hrs. old age group eggs can be preserved maximum days without any adverse affect. This group of eggs hatched after 25 days of oviposition and the bioassay of cocoon weight (3.2gm), shell weight (0.42gm) and ERR (68%) is significant. From the study, it is indicated that multivoltine eri eggs can be preserved in the particular embryonic stage and ages
