Table 5 Kaplan-Meier pair wise comparisons of the median survival times (MST) of An. gambiae s.s. females exposed to surfaces 1, 14 and 28 d after treatment with different concentrations (2 × 109, 2 × 1010 and 4 × 1010 conidia m-2) of B. 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

Comparison of: Different concentrations within same time post-application The same concentration between different times post-application
