Population abundance and feeding behavior of Bemisia tabaci when fed on wild-type (AC) and ABA-deficient mutants (not), grown under ambient O3 (AO3) and elevated O3 (EO3). (A) Population abundance (number per plant). Each value represents the average (± SE) of four OTCs (12 plants for each genotype per OTC). (B) ‘Nonpenetration' (NP, stylets are outside the plants), (C) ‘pathway' (C, mostly intramural probing activities between mesophyll or parenchyma cells), (D) ‘salivation' (E1, salivary secretion into sieve elements), (E) ‘phloem ingestion' (E2, ingesting the phloem sap), (F) total time to first E2, (G) ‘xylem ingestion' (G, stylet penetration of tracheary elements), and (H) derailed stylets (F, stylets are exhibiting penetration difficulties). Values are the mean (± SE) of 15 biological replicates. Different lowercase letters indicate significant differences between ambient O3 and elevated O3 within the same genotype. Different uppercase letters indicate significant differences between genotypes within the same O3 treatment, as determined by Tukey's multiple range test at P < 0.05.
