Trapinch and Diglett/Dugtrio are the ones who have it however keep in mind that the Arena Trap ability does not work against flying-types and Pokémon with the Levitate ability.
You don't actually select when to use a hidden ability. Say your opponent tried to run from battle or tried to switch pokemon, the Arena Trap hidden ability would stop them automatically. (If you opponent is a flying type of has the hidden ability "Levitate" then the Arena Trap ability wouldn't work, but it works for all other type and abilities).
well did you have it out in battle? if not it has to be out in battle with latios for arena trap to work. if you did have you trapinch out, then... either arena trap didn't work( witch would be weird) or i don't know. another Pokemon would be wynaut or wabuffet. it has the ability shadow tag and that keeps the Pokemon from escaping. i hope you catch the latios! :) -RR14
Trapinch. You can catch it in the desert. And if you just want a Pokemon to not flee there is also Wynaut and Wobbuffet.
You need the Pokemon with arena trap in battle or the wild Pokemon can flee
Well, no new Pokemon have Arena Trap, but The Pokemon Dugtrio does and Wobbafett has Shadow Tag, which is the same. There is one Pokemon I believe that has Arena Trap as a Dream World Ability...not sure though. Hope this helps!

"In Pokemon ruby can Pokemon run from trapinch?"Yes and no. Most Pokemon cannot run from trapinch because trapinch has the ability Arena Trap, but flying types are unnaffected by Arena Trap.
Mean Look Arena Trap (ability)

Sleep it with hypnosis, it cannot run if its asleep, or you can use the Pokemon ability arena trap or the move scary face. or use a shadow tag that's found with a wabafet
Diglett has an arena trap.
