Table 3 Diversion of mosquitoes from human landing catch (HLC), mosquito-electrocuting traps (METs) and BG-Sentinel (BGS) traps in position 1, located 3 m from freestanding transfluthrin passive emanators (FTPEs) or control to a person conducting HLC in position 2, 10 m from FTPEs or control

From: Semi-field evaluation of the exposure-free mosquito electrocuting trap and BG-Sentinel trap as an alternative to the human landing catch for measuring the efficacy of transfluthrin emanators against Aedes aegypti

  1. The percentage of released mosquitoes recaptured by each method is presented out of 800 Aedes aegypti mosquitoes released over eight replicates. The proportion recaptured is the arithmetic mean recaptured out of the total released
  2. aThe odds ratio (OR) estimates were derived from Stata output of position 2 relative to position 1 in the presence of transfluthrin or control, adjusted for temperature, humidity, compartment and volunteers and presented with 95% confidence interval
