Percentage pupation and Hazard ratio's of larvae exposed to unformulated floating fungal spores

Average percentage pupation (±S.E.) in the control and treated An. stephensi larvae exposed to Metarhizium anisopliae and Beauveria bassiana spores floating on the water surface for 1, 2, 3, 5 and 7 days (n = 3). The controls consisted of untreated trays filled with water at the same time as the treated trays. Hazard ratio's (HR) indicate the mortality risk of larvae as compared to the controls for both Metarhizium anisopliae and Beauveria bassiana spores
a. HR lower than 1 represents higher mortality in the control group.
