^aAedes Rio presenting RR₅₀ < 5 were considered susceptible, RR₅₀ between 5 and 10 were considered moderately resistant and RR₅₀ > 10 were considered resistant

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

Abbreviations: LC50, concentration that kills 50% of the animals; LC95, concentration that kills 95% of the animals
