Hawking radiation at the mouth of Schwarzschild wormholes

Question

I was researching a question for another post and it occurred to me that you might expect to see Hawking radiation at the mouth of wormholes.

Given the mechanism of Hawking radiation at the event horizon of black holes: virtual particle pairs forming at the edge and being separated by the event horizon; would virtual particles at the edge of wormholes likewise be divided? As I understand it, the trip is one way, which should cause the spontaneous formation of electrons and separation of positrons.

Am I on the right track or is this a ridiculous assumption?
I don't see this in the literature on Hawking radiation or wormholes. Can you point me to any resources?
If this wouldn't occur, why not?

A couple of points: a) the wormhole associated with the Scharzschild metric is not traversable. I suspect you're thinking of a Morris-Thorne wormhole. The Morris-Thorne wormhole is traversable in both directions and doesn't have a horizon. b) Hawking radiation is not due to separation of particles and anti-particles, but to separation of particles with positive and negative energy. See Black holes and positive/negative-energy particles for more details — John Rennie, May 28 '14 at 16:39
Good point about the Scharzchild metric. Would an Einstein-Rosen bridge be more relevant? — WillMcLeod, May 28 '14 at 16:42
I think Einstein-Rosen bridge is synonymous with Schwarzschild wormhole, though i wouldn't swear to that. The Morris-Thorne wormhole is the simplest traversible wormhole I know. — John Rennie, May 28 '14 at 16:54
According to Matt Visser Hawking radiation requires a horizon to exist. A traversible wormhole does not have any horizons therefore it will not produce Hawking radiation. — John Rennie, May 28 '14 at 17:17
