Growth of CPB larvae in the differential feeding assays. The CPB larvae were fed on Potato virus Y^NTN (PVY^NTN)-infected and healthy plants of cv. ‘Igor’, and on nontransgenic and coi1-plants of cv. ‘Désirée’. Fresh potato leaves of cv. ‘Igor’ were provided for the ‘control’ larval group every 24 h. Larvae were weighted as whole groups at 0, 2 and 4 dpi, and individually every day from 5 to 9 dpi. Error bars (5–9 dpi) show standard errors of the mean (n = 20). The statistical evaluation of differences in larval weight throughout the feeding assays is presented in Table S3 (Supporting information).
