Views, Pathauto and contextual filters
I couldn't understand what you exactly need but i guess that "banana" is the title of your node, the same value that you are using when you set up the pattern in pathauto settings, right?

So in this case you would have to set Node Title has a contextual filter, and then on "When the filter value is NOT available" you have to set  Provide default value > Raw value from URL > specify the position of your argument in the URL.

It would be nice if you give us more information about what do you need, please
