Table 1 Relative trapping efficacy of human landing catch (HLC), mosquito-electrocuting traps (METs) and BG-Sentinel (BGS) traps evaluated individually in a no-choice test and in competition with HLC in a choice test, in the presence of two freestanding transfluthrin passive emanators (treatment) and with no transfluthrin (control)
