Percentage of Lso-carrying and Lso-free psyllids observed on healthy and PVY-infected tomato plants after 2, 4, 6, and 24 h of exposure. Overall, Lso-carrying psyllids were more likely to settle on healthy tomatoes (P = 0.014), whereas the Lso-free psyllids settled on PVY-infected plants more frequently (P = 0.007). Asterisk indicates significant difference within observation time.
