Dave1950 knows his stuff. Had some in one of the lifts of pecan that went into my kitchen and bathroom cabinets and trim, they were active for five or six years until our pest control guy did some research and mixed up a special cocktail that finally put an end to them. Several doors fell off along with chunks of face frames that had gradually been converted to powder by the beetles. I had to splice back together with spare wood from the project.
I would suggest heating the stock in a cardboard box with an electric space heater for a day before proceeding.
As has been said, nothing you can fill it with will look good, so either plane it off and scab on a thin veneer to the panel, or better yet just ignore it and finish exactly as you would if the trenches weren't there, just clean out all the dust before finishing.
Another thought is fill them up with a mix of fine turquoise sand and clear epoxy after the base stain color is put on.
Last build I did was riddled with holes, and some of this unfortunate one remained in the finished stock. I just filled it with tinted Acra-Glas like the rest of them and let it be seen.
