Fig. 5

Effects of a window of insecticide control. In contrast to Fig. 4, the control is not constant throughout the year, but instead a window of insecticide control is applied at different times of the year. It is assumed that within the window the control efficiency is 0.2, and 0 elsewhere. The length of the window is fixed to 50 days and the starting day of the window varies, plotting the difference in observed total adult abundances to the uncontrolled equivalent (a). Areas in white show no differences in abundance; red show greater abundance; blue show less abundance, compared to the uncontrolled population. In b, the mean differences over the year for varying starting times are plotted. The control strategy is run for one year only
