One option is to install
apt-show-versions. For example, to find packages installed from unstable:
$ apt-show-versions | grep unstable

aptitude you can run the following command:
$ aptitude versions '~VCURRENT (~Aunstable|~Aexperimental) !~Atesting' --group-by=none

~A) and are not present in the testing archive (
--group-by=none option serves to produce a more terse output.
