Antherea Pernyi overwinter

I have just raised a batch of Antheraea pernyi and read that they will emerge about a month after they form a cocoon. If I wanted to delay the emergence till next spring could I place then in the refrigerator? If I let a few emerge and mate could I place the ova in the refrigerator and have live ova next spring? How does one overwinter this species?

Thanks in advance for any advice,
Richard
