Table 2. Description of the parameters used for the malaria basic reproductive number model.

Description Formula and calculation
ma Number of mosquito bites per person/day Average number of mosquitoes collected per person/day during the adult mosquito sampling study
a Frequency of the vector mosquito feeding on a person/day a = C/x
C Proportion of mosquitoes feeding on human blood instead of other animals 1/3 proportion fed on human for An. maculatus s.l. and An. minimus s.l. [47]
2/3 proportion fed on human for An. dirus s.l.
x Gonotrophic cycle length, measured by the interval between blood meals taken 2.35 days for An. maculatus s.l. [47, 48]
Two days for rainy season and three days for dry season for An. minimus s.l.[49]
Three days for An. dirus s.l. [23, 50]
b Proportion of female mosquitoes developing parasites after taking an infective blood meal Dependent on genetic and non-genetic determinants [51, 52], conservative estimate of 0.5 for all [53]
p Daily survival probability of adult mosquitoes A1/X
A Average proportion of parous mosquitoes Proportion parous from the mosquito survival data
n Development days of parasite in mosquito (sporogonic cycle) using Moshkovsky's method For P. falciparum the thermal sum required to complete parasite development is 111°C above 16°C. For P. vivax the thermal sum required to complete parasite development is 105°C above 14.5°C [54]
Average Tdry in study area = 23.2 °C
Average Train in study area = 23.3 °C
r Rate of human recovery (1/number of days) 60 days, so 1/60 [55, 56]
