Figure 3

Feeding visits and durations in all experiments. Numbers in boxes represent the mean value on each larval development day (LDD; colour-coded) for feeding visits (ab) and feeding duration (fj). Bold italic numbers in boxes represent statistical differences to the control on this LDD (Bonferroni-Holm type I error-corrected adjusted p of Student’s t-test after significant one-way ANOVA; number of tests used for p-value adjustment = 3). The upper ends of the coloured boxes show the mean cumulative value on the y-axis, equivalent to the sum of all numbers below. If dotted, significant statistical differences (same test) of cumulative values to the control were present. Graphs (e,j) show the mean of (ad and fi), respectively. Treatments were in most cases below the controls daily and cumulative and value, but levelled throughout LDD 6 (red boxes). The upper ends of LDD 6 represent the total value until cell capping. Feeding duration was strongly correlated to the number of feeding visits. Parameter means of all experiments (Mean) were not significant due to the results of July 2016. Abbreviations: CLO = clothianidin; THI = thiacloprid; ppb = parts per billion; SEM = standard error of mean. Samples sizes (n) are number of analysed cells in the experiments (a,f: May 2016, b,g: May 2018, c,h: June 2016, d,i: July 2016) and the number of colonies (e,j: Mean).
