Figure 4. Effect of permethrin on fungal virulence.

Mean (± SEM) percentage mortality measured at day 4 of uninfected (white), Beauveria-infected (grey) and Metarhizium-infected (black) kdr mosquitoes from the laboratory colony (left) and field population (right), which were exposed to permethrin (P), fungus (F) or both (F+P) on day 0. Data represent five and four replicates of 28 laboratory and field mosquitoes, respectively. Significant group differences are indicated by non-corresponding letters.
