Table 4 Relative recapture of competing human landing catch (HLC) in the presence of HLC, mosquito-electrocuting traps (METs) and BG-Sentinel (BGS) traps in a choice test in the presence of two freestanding transfluthrin passive emanators (treatment) and with no transfluthrin (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 average proportion of released mosquitoes that was recaptured by each method by HLC in position 2 is presented out of 800 A. aegypti mosquitoes released over eight replicates
  2. aRelative recapture in HLC position 2 when HLC is conducted in position 1 compared to the MET and BGS trap in position 1 in both the treatment and the control arms
  3. bThe odds ratio (OR) estimates were derived from Stata output adjusted for temperature and humidity and presented with a 95% confidence interval
