Table 2 Number of female Anopheles gambiae s.l. collected nightly from each treatment of the five experimental hut trials, the proportion that showed fungal growth after death (Sporulation %) and the average time to death (g) derived from the Weibull models in days (see Additional file 1)

  1. As sporulation rates in the trials 2 and 3 were zero or very low, we only calculated separate 'average time to death' for fungus-infected individuals (those that sporulated) and fungus-uninfected individuals (those that did not sporulate) of trials 4 and 5. In trial 1, the number of mosquitoes collected in exit traps of treatment huts was too low to calculate 'average time to death' ('nd' in Table). Ma: Metarhizium anisopliae; Bb: Beauveria bassiana
