Figure Lengend Snippet: Toxicity ( a , b ) and comparative effects of synergists ( c , d ) on mortality caused by permethrin and deltamethrin to larvae (L4) of two Brazilian strains of Aedes aegypti . ( a , b ) The lines denote the lethal concentration (LC) values estimated based on concentration-mortality bioassays using probit analyses. Symbols show the averaged mortality for each insecticide concentration applied to each population of A. aegypti . The vertical bars represent the standard error of the average (SE). ( c , d ) The effects of the synergists piperonyl butoxide (PBO), diethyl maleate (DEM) and triphenyl phosphate (TPP) on the mortality of the resistant population caused by pyrethroids at the LC 50 obtained for the resistant strain. Asterisks indicate significant differences in relation to the unsynergized insecticide (one-way ANOVA with Scheffe’s post hoc analysis, P < 0.05).

Figure Lengend Snippet: Pyrethroid resistance-associated amino acid substitutions in A . aegypti sodium channels. ( a ) Schematic representation of the mosquito sodium channel protein (AaNa v 1-1) indicating two knockdown resistance mutations in IS6 and IVS6. Sodium channels are large transmembrane proteins with four homologous repeats (I–IV), each having six transmembrane segments (S1–S6). Residue positions correspond to the cockroach BgNa v protein (GenBank number: U73583). Dose-response curves of permethrin ( b ) and deltamethrin ( c ) on BgNav1-1a, V410L, F1534C and V410L + F1534C cockroach sodium channels. The method for determining the percentage of modified channels is described in the Materials & Methods section.
