Does the sun effect praying mantis?

Yes. Mantids, like anything else, are affected by the sun. The vitamin D is good for them, and most mantids can benefit from the warmth. Exercise caution, however, if you have a pet mantidm because if they are left in direct sunlight, they may get overheated and die. If you have a pet mantid, it is a wise idea to place them in indirect sunlight, so that they may receive the benefits, without the risks. Keep an eye on the temperature even then, though, because, like anything else, a mantid can die of heat stroke.
