  1. Note: n: absolute number of mosquitoes captured; MTY: mosquitoes per trap and year; aCRR: adjusted capture rate ratio; 95 % CI: 95 % confidence interval; Bold numbers: significant difference in aCRR (P < 0.05). Ae.: Aedes, An.: Anopheles, Cx.: Culex, w/o: with/without
  2. Comparisons were made between traps augmented with CO2 baits and those with no baits and between traps placed in indoor and outdoor locations. Models are adjusted for region and season
