Huanglongbing, China? Seams like there's some bad stuff coming in from China lately... Or maybe I am just to cynical..

Maybe a leap too far ?
Huanglongbing is just the Chinese name of a widespread Citrus disease.
I would be more inclined to blame the Romans. So many plant and animal disease organisms have Latin names !
As for Huanglongbing, it is more commonly known as HLB. Blame the Corporations ?
Interesting that the Australian Citrus species have resistance to HLB, even though we don't have the bacteria that cause it or the insect vector.
Maybe something carried from the ancient past in the plant genes.
A very strong case for the conservation of ecosystems and plant species.
Who would have thought ' Finger Limes " could be so important to the future of the Orange Juice Industry ?
You never know what else you may need from wild plants in the future ?

You make a good point, but in this case the disease did come from China.

The more adjacent species seem to have better resistance. Poncirus does, too.

It seems most of rutaceae can host psyllids and many can get HLB, but it doesn't seem to do anything to them. HLB seems to specialize in mainline citrus.

Makes sense if Citrus came from China. Some of the species evolved there. Pest and Diseases also.
Some modern cultivars are even called Mandarins !!!

Murraya is a very popular ornamental in Australia, and also a potential problem.
Many other wild Rutaceae, like Microcitrus, Acronychia, Flindersia, just to name a couple.
