There was a thread about that not a long ago:

I've kept two species S. gastrica and H. membranacea. Adult females survived 9 - 12 months, adult males 5 - 7 months. You can add 3 - 5 months for young mantids.

Any species of mantis is gonna be lucky to get to 18 months. Most will be dead in around 12 months.
