Acquisition of Liberibacter by psyllids on I. batatas and C. arvensis.

a PCR confirmation that psyllids obtained from the infected colonies carried Liberibacter; number of infected groups of insects divided by the total number of experimental plantsb Number of plants on which uninfected psyllids acquired Liberibacter divided by the total number of plants exposed to Liberibacter. PCR amplicons were observed for positive controls, but not for negative or single primer controls. None of the psyllids from control plants were infected with Liberibacter.c Uninfected psyllids placed on plants for 48 hours immediately after an inoculation access period of 48 hours.d Uninfected psyllids placed on plants for 5 days, three weeks after initially releasing infected psyllids on plants for a 1-week inoculation access period.Acquisition of Liberibacter by psyllids on I. batatas and C. arvensis.
