I constructed a much improved Truffle Worm autofarm after the changes to Truffle Worms in 1.3. Truffle Worms can now be killed by hostile mobs, and hostile mobs are much more difficult to kill via traps in expert mode, so the previous version of the farm is no longer very effective. The previous version can be found here:

The new version uses a very different and vastly superior approach, and is significantly easier to build because it avoids the need to farm multiple worlds for 16+ Lihzahrd Dart Traps. First, let's take a quick look at the action, and then discuss how the new farm works.

Explanation:
The spawn surface is lined with actuated teleporters, and hostile mobs that spawn are instantly teleported away. Truffle Worms and Glowing Snails cannot be teleported, so they stick around and crawl into a horizontal tunnel, and eventually drop into a chute where the player is positioned. The mobs are teleported to a teleporter that is at least 252 tiles away horizontally or 142 tiles vertically from the player's postion which causes the mobs to instantly despawn (source: http://terraria.wiki.gg/NPC_despawning) and thus prevent any backwards-teleportation. Backwards-teleportation is usually the main issue in using spawn surface teleporters, and thus it's much better to despawn mobs than to send them into a kill chamber. Plus, since despawning is near instantaneous, it generates a much more rapid turnover of mobs than taking the time to kill them.
There is one other major advantage to despawning the spawned mobs - it also instantly removes the Skeleton Merchant, who is otherwise a major problem if allowed to stick around. When he arrives all mob spawns are blocked.
To achieve the teleportation of mobs, a dummy ghost moves across a hoik track below the spawn area in cyclic fashion, activating pressure plates along the way. Each pressure plate is connected to a teleporter above in the spawn area, and all the wires from the teleporters are joined together and lead to the distant teleporter. When 3 or more teleporters are connected with the same wire, it is necessary to use a pressure plate closest to a given teleporter to teleport any mob from that specific teleporter - that pressure plate is incapable of teleporting mobs from any other teleporter.
Note that the mobs can still unfortunately spawn directly on top of the Truffle Worms, killing them instantly before they are teleported away. However, this is completely unavoidable, and doesn't happen all that often so the Worm capture rate is still very high.
Schematics:
The player first enters the teleporter in the bottom right area where the hoik track is, and is hoiked across that track sending two dummies, in staggered fashion, into the teleportation system on the left. The player then starts autoswinging the net, and when farming is finished the player pulls the right lever to teleport back to home base. The green wire on the far left extends 252+ tiles to a teleporter to despawn the mobs. The blue wire at the bottom extends to home base. The height of the chute must be at least 11 tiles to ensure that the worms don't run away from the player.
The farm can also be constructed right after the first mechanical boss is defeated and access to teleporters is gained by using regular dart traps instead of spiky ball traps. The dart traps take about 4 times longer to defeat the bulbs, but they are still pretty effective as can be seen here:

Schematic:
The player is teleported into the farm to the immediate right of the dummy. The player then walks over the 16 pressure plates (without using any speed-boosting gear) and stops at the end. Walking over the pressure plates this way generates a stream of evenly spaced darts, and the dummy ghost keeps the darts continuously firing by activating the pressure plates in the track to the left.

To reach the Truffle Worm farm, input C1 in the teleporter hub. There's a net in the chest to your right when you teleport in.
