What Citrus Problem is this?

maxzoo starts with ...
So my Eureka lemon has some fruit that look strange. The tree is only a couple of years old but i would say that half of the fruit that formed were deformed and the other half are fine- looking regular. I do have to kill off stink bugs everyday from the tree and I am wondering if it could be linked to them?

My little cumquat tree also has some fruit with a similar problem..its like a scaley chalky coating that can be scratched off with your nail, also noticing a few stink bugs hanging around that tree too..

Any thoughts?
