Trouble with bees

Australian bees are doing very nicely. They are in huge demand here for pollinating local almond orchards and in huge demand overseas because they are disease free. But unless we're careful problems plaguing American hives could turn up here. Colonies are collapsing in the US because the bees are overworked, poorly managed, and have a bug called varroa destructor, which is said to look like a baked bean with fangs. Quarantine is tight to make sure it doesn't enter Australia as a stowaway. Reporter Stan Correy.
