Figure 3

The expected period in days for Plebeia droryana larvae to develop into queens and workers as a function of the chlorpyrifos (CPY) dose in larval food. The Poisson regression model (log link) is shown. Legend: dots, observed data (jitter plot); full line, predicted model; shaded area, 95% confidence interval (generalised linear mixed model [GLMM] Poisson, estimate = 4.43, standard error = 1.29, z-value = 3.4, P < 0.001); the smaller chart, density; dotted lines, means.
