aAll night biting rate was calculated with a calibration factor of 93 % biting before midnight. This figure was calculated from the biting profile presented in the first section of this paper
bDaily EIR [infective bites per person per day (ib/p/d)] = sporozoite rate × biting rate (18.00–06.00 h)
cAnnual EIR [infective bites per person per year (ib/p/y)] = sporozoite rate × biting rate (18.00–06.00 h) × 365
dThese sample periods include mixed P. falciparum and P. vivax infections (one from 2013, one from Jan–Feb 2014 and thus two mixed infections overall)
