Table 5 Analysis of colony development metrics: weight of workers, weight of larvae, weight of drones and number of pupae.
Statistical test | Model | Significant effect of any treatment | Parameter estimate (PE) + confidence intervals (CI) | Chi-squared, degrees of freedom, P-value |
|---|---|---|---|---|
LMM | Weight of workers ~ treatment + colony weight + (1|block) | No | Crithidia only PE = − 0.947 (CI = − 3.832 to 1.976) Sulfoxaflor only PE = − 0.675 (CI = − 3.679 to 2.306) Sulfoxaflor + Crithidia PE = − 0.486 (CI = − 3.357 to 2.410) |  |
Kruskal–Wallis | Weight of larvae | No |  | X2 = 2.461 DF = 3 P = 0.483 |
Kruskal–Wallis | Weight of drones | No |  | X2 = 2.139 DF = 3 P = 0.544 |
LMM | Number of pupae ~ treatment + colony weight + (1|block) | No | Crithidia only PE = − 1.313 (CI = − 4.883 to 2.256) Sulfoxaflor only PE = 0.672 (CI = − 3.017 to 4.363) Sulfoxaflor + Crithidia PE = − 1.065 (CI = − 4.624 to 2.493) |  |
