Citation: Walter, A.J., Hall, D.G., Duan, Y. 2010. Candidatus Liberibacter asiaticus is present in orange jasmine and Asian citrus psyllid [abstract]. Florida Entomological Society Annual Meeting, July 25-28, 2020, Jupiter Beach, Florida. Technical Abstract: Orange jasmine, Murraya paniculata, is a common horticultural plant in Florida, and an alternate host of the Asian citrus psyllid, Diaphorina citri Kuwayama. Orange jasmine has also been reported to harbor the bacteria Candidatus Liberibacter asiaticus, the causal agent of huanglongbing disease. We present the first findings of an ongoing survey of several orange jasmine populations in Saint Lucie County. We report the presence of Tamarixia radiata, a biological control agent introduced in 1998, parasitizing psyllid populations on jasmine. Ca. L. asiaticus is present orange jasmine and in psyllids reared from jasmine, but the titer of bacterial DNA is very low. Because the bacteria are present at such low levels, the importance of psyllids originating from orange jasmine to epidemiology of Huanglongbing in citrus is uncertain.
