Considering that white sapote is related to citrus, is it susceptible to citrus greening disease?
'?

I have citrus which has the greening symptoms and I have 2 white sapote trees that do not
have the symptoms. I have seen the bird poop caterpillars on both the white sapotes and citrus trees
which now makes sense that they are related.

 "In category 2, Casimiroa edulis (White sapote) was reported as a nonhost for ACP, with a score of 0 for both adult and nymph infestations".   It seems that the white sapote is not a host for the psyllid which carries HLB.

Aphid could cross contaminate infected citrus to white sapote in theory? My white sapotes do not develop to full maturation anymore even with cross pollination it's been years 10+. Biggest they ever get now is golf ball size if that

"White sapote is not a preferred host for the psyllid (Halbert and Manjunath 2004; Westbrook et al. 2011). Since this plant is grown in California by rare fruit growers and horticulturists, mainly in regions where citrus is cultivated, and it may act as an alternate host for HLB, regulatory precautions are warranted."
