Eight replicates per species (50 females per replicate) were tested (n = 400). For each species, different lowercase letters within a column indicate significant difference according to one-way ANOVA with post hoc Tukey’s honest significant difference test when P < 0.05. For other abbreviations, see Tables 1 and 2
*P < 0.05 (significantly more females in the treated BGS trap)
^aStudent’s t-test between untreated and treated traps (P < 0.05)
^bPercent attraction = (no. of mosquitoes in treated traps – no. of mosquitoes in untreated traps)/(no. of mosquitoes in treated traps + no. of mosquitoes in untreated traps) × 100
