Table 2 Resistance profile of Aedes Rio mosquitoes to temephos, deltamethrin and malathion

From: Insecticide resistance, fitness and susceptibility to Zika infection of an interbred Aedes aegypti population from Rio de Janeiro, Brazil

  1. aAedes Rio presenting RR50 < 5 were considered susceptible, RR50 between 5 and 10 were considered moderately resistant and RR50 > 10 were considered resistant
  2. Notes: lethal concentration (LC) values expressed as mg/l, mg/m2 and g/m2, respectively. Confidence intervals (CI) of lethal concentrations, slope and resistance ratio (RR) 50 and 95 are also shown
  3. Abbreviations: LC50, concentration that kills 50% of the animals; LC95, concentration that kills 95% of the animals
