  2. Notes: Mortality percentages correspond to the discriminating exposure time DT=30 min for both insecticides [40]. The average values of four insecticide treated replicate bottles are presented. n1 and n2 refer to the total number of female mosquitoes tested against deltamethrin and malathion, respectively
  3. Abbreviations: ATT, Attica region; CI, confidence intervals; LC, laboratory colony; R, resistance; S, susceptibility (according to WHO recommendations for CDC bottle bioassay guidelines, 2010)
