Table 2 Kaplan-Meier pair wise comparisons of the median survival times (MST) of An. gambiae s.s. females exposed to 2 × 1010 conidia m-2 of co-formulated Metarhizium anisopliae ICIPE-30 and Beauveria bassiana I93-825.

From: Infection of the malaria mosquito, Anopheles gambiae, with two species of entomopathogenic fungi: effects of concentration, co-formulation, exposure time and persistence
