You will find that most conventional demonology revolves a great deal around medieval christian views of demons, with some influence from the same Hebrew mystical traditions that influenced the Christian belief in angels.
You'll also find that these same influences can be traced back go Greco-persian influences, where we both get the word Demon...
It is argued that this word has been derived from Daemon, which was actually generally a good/benevolent spirit... though in greek mythology "good" spirits are still capable of wrath/jealousy/etc. often enough. You will also find that Christians picked up upon Platos metaphorical use of the word Daemon as a more evil spiritual being.
Similarly, within Hebrew traditions the word came to be recognized in reference to evil entities. This, as with most such monotheistic practice, can largely be traced back to Zoroastrianism, the first monotheistic religion. Here we see the origins of the "One god" belief, where there was also a parallel evil force. Other beings, Devas, etc. that were previously worshiped in nearby religions became viewed as either lesser entities who served the "one" god or evil beings, who served the opposition.
We do find some literature about these entities, and it seems the traditions and manner in which these beings were discussed evolved to also give us the manner in which Judeo-Christian demons are discussed. To my knowledge though, much of this tends to date back to similar medieval manuscripts as give us the Demonology traditions.
I'm certain that somewhere in these Western traditions you'll also find some of the Hindu culture's influence, as there was also heavy interaction within this Asian sub-continent and the ancient Greek world.
What interests me about all such entities though, is that outside of polarized monotheistic religions demonology is often relatively nonexistent. Instead you find discussion of entities that are both good and evil. "Demons" are certainly possible, but often they are capable of the occasional good act as well as the evil for which they are known, while more goodly beings are also known for committing evils.
But then I suppose depending on your outlook the fire and brimstone over Sodom and Gomorrah, turning those who look back into pillars of salt, visiting plagues upon ALL first born males, etc. are all acts carried out by angels, rather than demons. Good and evil seem to be defined in these terms by who's side you're on rather than what you do to those around you.
It's worth noting too that most demonology as well as angelic correspondences are all rooted within the apocryphal... With the exception of medieval manuscripts that were sanctioned by the church within witch-hunting efforts, most such correspondences are not officially recognized by most modern Christian faiths, and when you boil it down most of the names we find within the bible for angels and demons are Hebrew titles rather than true names.
This naming pattern rings true to my personal experiences, where spirits tend to identify themselves in a manner that speaks more of their purpose, current intention, and general "personality" than clinging to any specific name.
