  1. 1The three treatments include: non-viruliferous B. tabaci whitefly feeding on non-viruliferous cucumber plants (NVW vs. NVP), viruliferous B. tabaci whitefly feeding on non-viruliferous cucumber plants (VW vs. NVP), and viruliferous B. tabaci whitefly feeding on viruliferous cucumber plants (VW vs. VP). 2Data are means ± SE. 3Letters immediately after the mean values represent the comparison of biotype B on plants under different treatments. Letters after the mean values indicate statistically significant among treatments (Tukey test, P < 0.05). 4Asterisks * or ** indicate a statistically significant difference between biotype B males and females on plants under the same treatments at P < 0.05 or P < 0.01. 5Percentage of E (%) = equals the percentage of total duration of E (E1+E2). EPG waveforms: C = pathway; pd = potential drop (intracellular puncture); E1 = phloem salivary secretion; E2 = phloem sap ingestion. E=E1 + E2
