Table 1 Survival of mosquitoes exposed to Imidacloprid, fungus and Imidacloprid+fungus during three different time periods

From: The combination of the entomopathogenic fungus Metarhizium anisopliae with the insecticide Imidacloprid increases virulence against the dengue vector Aedes aegypti (Diptera: Culicidae)

Exposure time (h) Treatments % Survival ± SD S50
  TWEEN 83.3 ± 2.85 a ND
  IMI 85.5 ± 2.67 a ND
3 FUNGUS 51.1 ± 6.01 b ND
  IMI + FUNGUS 44.4 ± 8.25 b ND
  TWEEN 80 ± 2.43 a ND
  IMI 84.4 ± 2.82 a ND
6 FUNGUS 26.6 ± 8.48 b 3
  IMI + FUNGUS 11.1 ± 11.34 c 3
  TWEEN 83.3 ± 2.67 a ND
  IMI 85.5 ± 2.47 a ND
12 FUNGUS 23.3 ± 10.6 b 3
  IMI + FUNGUS 7.77 ± 12.32 c 2
  1. Results followed by the same letter indicate no significant differences when using Duncan's post-hoc test (5% probability). Values for S50 (mean survival time) were calculated using Kaplan-Meier survival analysis. ND = Not determined.
