Bug Scale

I've got bugs on my orange trees.

I grew the trees from seeds, taken from a bitter orange tree near here that was subsequently felled. So I'd really like to help these trees to grow. But some of the trees are under assault from a bug. The bugs are orange and mobile when young, becoming white and powdery and immobile as adults. They produce an orange liquid - but not red like Cochineal - when you squish them.

Mealybug? or Scale?

Which bug is it?

Is it Planococcus citri, a citric Mealybug?

Or is it Icerya purchasi, the Cottony Cushion Scale?
