    Like most animals, insects need oxygen to survive. Instead of breathing through their mouths (or noses, if they had them), though, they breathe through a series of openings called spiracles - usually one on each segment, located laterally. Insects, therefore, *can* suffocate if you place them in an environment where they're oxygen-deprived. As for pain...well, that depends on how you interpret "pain." Most insects demonstrate stereotypical avoidance behavior when presented with something potentially dangerous (a heated prob, for example), and there *is* evidence for nociception - "the neural processes of encoding and processing noxious stimuli" according to Wikipedia - in at least one insect: dx.doi.org/10.1016/S0092-8674 Will open in a new tab or window(03)00272-1
    I'll defer to an insect physiologist, though, to give you a definitive answer!
