ok, i'm not sure wether this is the right place to post this or not but...

can anyone help me with this.

i want to know the name of all the scales which are used in writing psychobilly music?

help is very very appreciated

Because it's really just darkened up rockabilly, you'll see a lot of blues scale.

It's really just the picking and tone that makes it.
Most music in general is based around the major and minor scales. It doesn't vary much between genres. The lead guitar in most types of rock music usually involves the minor pentatonic and blues pentatonic scales. Psychobilly is no exception.
