Sorry for the delay - it's now Sunday and this post only just arrived.

Short answer:  Image/Select/Select by Color  should do it.  If you want
to make the selected (or not selected) pixels transparent, make sure you
have an alpha channel.  You can't do this on the background layer.

An alternative is the Image/Filters/Colors/Color_to_alpha plug-in.

Experiment with both of these and see what works for you.
