Overexpression of Sg2204 in wheat promoted Schizaphis graminum feeding and enhanced aphid body weight and fecundity. (a) Feeding behaviour parameters of S. graminum, including durations of stylet probing (C), salivation (E1), phloem ingestion (E2) and time from the start of EPG to the first sustained E2, when feeding on wheat leaves treated with empty vector (EV) and pEDV6:Sg2204. At least 10 biological replicates were performed for each group. (b) Body weight of S. graminum after feeding on wheat leaves inoculated with EV and pEDV6:Sg2204 for 7 days (n = 15). (c) Number of nymphs produced by S. graminum after feeding on wheat leaves infiltrated with EV and pEDV6:Sg2204 for 5 days (n = 20). Data are presented as the mean ± SE. Asterisks above the bars indicate significant differences between controls and treatments (*P < 0.05; **P < 0.01; ***P < 0.001; Student's t test).
