Look at the file apalike.bst, which will tell you want fields are defined. (There is no field "translator", by the way.) And you can use apalike2, if you wish. Just hit the "browse" button in the dialog where you choose a bibliography style, and then go find the file apalike2.bst.
It is, by the way, not that terribly hard to modify these styles once you get the hang of it.
