Mosquito species (An. stephensi (As) versus An. gambiae (Ag)), B) fungus species (B. bassiana (Bb) versus M. anisopliae (Ma)) and C) larval stage (Late (L3-4) versus early (L1-2)), for different concentrations (2.5, 5, 10, 20 mg/441 cm2) of the fungi. Asterisks indicate significance (P < 0.01) following adjustment for multiple comparison. Letters within parenthesis represent the graphs in Figure 1 that have been compared in the analysis.
