^aIn Brazil, localities with Ae. aegypti populations exhibiting temephos RR₉₅ higher than 3.0 are subjected to insecticide substitution [31]. Note that RR is based on dose–response assays, distinct from the remaining qualitative tests depicted in this table.
^bthe diagnostic dose (DD) of deltamethrin used was 5 μg/bottle [9]. According to this assay, mortality below 80% indicates resistance [32].
^cthe diagnostic dose of triflumuron employed, equivalent to twice the EI₉₉, was7.9 μg/L.
