Table 2. Percentage of C1 psyllids with detectable levels of CLs.

Treatments*	Conventional PCR % of psyllids	Nested PCR % of psyllid
I-5 weeks	6.0	53.0
II-5 weeks	13.0	26.0
II-12 weeks	0.0	38.0

^*Transmission studies were performed with the low-CLs psyllid colony. A conventional and nested PCR was used to assess CLs percentage in sampled population at 5 and 12 weeks of plant exposure to psyllids.
