  1. Results are shown as the mean survival rates (% ± SD) after spraying mosquitoes with 1 × 108 ml−1 (conidia or blastospores) of two isolates (ESALQ 818 and LEF 2000) on day 3 or day 7 following spraying of mosquitoes with 1 × 107 ml−1 (conidia or blastospores)
  2. The mean survival percentages followed by different letters indicate statistical differences when comparing values (columns) using ANOVA followed by Duncan’s post hoc (5% level). Control data for each treatment group were combined, and a single mean survival rate was calculated
  3. nd not determined
