What is this disease/pest on my orange tree?

I am not sure what is ailing this old tree but hope to save it, as it used to bear the sweetest, seedless oranges.

Attached are pictures of the leaves. I would like to know if anyone can identify what this is and suggest a treatment. I live in Los Angeles, County.

Thanks!

The cottony stuff is likely young woolly whiteflies.

Whiteflies and leafminers. Whiteflies are on the underisde of the leaves, so sometimes you don't notice them until they get bad. They won't kill the tree, but they do cause damage to the leaves.
