¹ For parameters associated with time including “durations” and “time to an event”, all units are minutes.

The parameters 1-10 were calculated for each insect and then averaged over all insects.

Recording that begin with probe = the time when 1st probe begins = non-probing duration from begin of the recording to the 1^st probe

Total number = number of occurrences of a specific waveform

Total duration = total time in a waveform (summed over all waveform occurrences)

Mean duration = average waveform duration (total time divided by number of occurrences)

Time to the 1st E(pd) within probe = time from beginning of a probe to the 1st E(pd) within that probe

² Probabilities were calculated from a general linear model (Two-Way ANOVA) for a 2 x 5 factorial design (parameters 1-10). Significant

differences are highlighted in red (P ≤ 0.05).

³ Letters immediately after the mean values were derived from the comparisons of different host plants within the same whitefly species.

Means followed by the same letters do not differ significantly (Tukey test, P ≤ 0.05).

⁴ Comparison of feeding behaviors of B. tabaci B and Q adults on each of the five host plants. Significant differences are marked

with an asterisk (Independent-Samples T test, P ≤ 0.05)
