The studies on White Sapote in Florida in the last decade were negative. I would like to have a reference to a study with the opposite result.

Not much to go on here, but I found citrus psyllid (African) (Trioza erytreae) which specifically mentions Casimiroa edulis as being a host for the African Citrus Psyllid and within that page makes mention that the significance is that it's a vector for HLB.

A couple of studies which indicate Casimiroa is not a host for Asian Citrus Psyllid are http://www.senasica.gob.mx/includes/...80&idurl=27167 and a spread sheet with various HLB related studies, "Liberibacter publication list (2000-2011) (Excel)"
http://citrusgreening.org/Liberibact...ion%20list.xls

I don't know of any studies where they have attempted to infect Casimiroa manually so it's probably safe from infection here in the US unless the Asian Citrus Psyllid is introduced as well.
