The experiment results showed that at the beginning of diapause, some inhibition existed in the metabolism of converting glycogen to sorbitol and glycerol in the artificially synthesized hormone induced diapause eggs and it led to increment of trehalose, sorbitol and glycerol in the eggs and advancement of diapause termination in them. As a result, some eggs could not complete fetation and died before hatching.
