Temephos and deltamethrin resistance ratios (RR95) and the 95% confidence interval estimated in four Brazilian Ae. aegypti populations. The allelic frequencies of the kdr mutation Val1016Ile (pyrethroid target site) and enzymatic activities (MFO, EST with three different substrates, and GST) are also shown.

aData originally reported by [33]. Enzymatic activities (MFO, EST with three different substrates, and GST) were classified as normal (regular font), altered (italic and underlined font), or highly altered (italic and bold) if these values ranged, respectively, below 15%, between 15 and 50%, or above 50%.
