  7 Unformulated 1.0 (0.5-2.0) 0.816
   WaterSavr 1.1 (0.7-1.8) 0.477
   ShellSol T 1.5 (1.0-2.2) 0.030
Beauveria bassiana 0 Unformulated 36.1 (8.9-146.8) <0.001
   WaterSavr 10.5 (4.7-23.5) <0.001
   ShellSol T 137.9 (18.0-1053.4) <0.001
  7 Unformulated 0.9 (0.4-1.7) 0.716

  1. Hazard ratio's (HR) indicate the mortality risk of An. stephensi larvae exposed to unformulated, WaterSavr-formulated and ShellSol T-formulated Metarhizium anisopliae and Beauveria bassiana spores, 0 and 7 days after application (n = 3)
