Figure 2. Effect sizes of floral resource effects. Differences
in estimated marginal means between different types of floral resources
are illustrated as dots. Error bars indicate 95% confidence intervals.P -values < 0.05 are shown. To avoid confounding effects
with spray treatment (Amistar or control) only the control group was
considered for the exposure period and the final assessment. No
confidence intervals for the number of males for comparisons with
buckwheat are shown as there were no adult males found in the control
colonies placed in buckwheat cages.
