Pairing of Argema mimosae

Dear breeders,
I have question regarding pairing of Argema mimosae in captivity.
My first males was very old when first female hatched. I tried to handpair they and male start to copulate in the evening.
In the morning he was died. Female das not laid no one ova until now, she is 4 days old.
Another males are not to copulate and new females start to oviposit in the body of males in the time of trying of handpairing.
My friend has same situation with A.mimosae...
I never seen before so strange situation. I have another 8 cocoons of A.mimosae and they will start to hatch.
So if anybody have good experience with pairing of Argema mimosae in captivity please inform me about good working method.
I'll be very grateful for the any information.
Best regards,
Anton.
