Pre- and post-intervention total numbers of P. orientalis and trap nights are aggregated across three experiments and presented according to treatment types and trapping methods.

¹ total numbers of trap nights represent the sum of chemical knockdown (KD) events inside sleeping huts; a single CDC light trap (LT) set per household at outdoor sites per night, and a set of 10 sticky traps (ST) set at each outdoor and peridomestic site per night. Each set of 10 STs is considered a single trap-night.
