Yes, I have heard that termites really like pine. Which is why it's a good idea to build the sill plate from heart redwood or treated lumber. And fir is a more resistant wood (but not termite proof), which may not be as attractive to termites as pine.
And yes, here in most of California I suppose the termites are not as problematic as in the Southeast. But they can be a problem just about anywhere.
