Table 3 Variables and parameters for the population model

From: Prospective malaria control using entomopathogenic fungi: comparative evaluation of impact on transmission and selection for resistance

Variable or Parameter Symbol Comments & Constraints
Period number (periods over which the population is tracked)* n 0<n
Dominance of resistance allele d dominant d = 1
   recessive d = 0
Genotype (normal allele s, resistant allele r) g (s,s) g = 1
   (s,r) g = 2
   (r,r) g = 3
Proportion of total population having genotype g at start of period n G g,n  
Proportion of the population resistant at start of period n R n  
Average number of infectious bites per mosquito in population in period n M n  
Size of initial population (susceptibles in the presence of treatment) as proportion of base population (susceptibles without treatment) J value from FCM
Population size in period n as proportion of initial population size W n  
Average infectious bites during one time period from an untreated population q value from FCM
Number of infectious bites from treated population during time period n, expressed as a % of the number of infectious bites during one time period from a susceptible population without treatment, Q n Chosen measure of control
Number of periods between egg-laying and adult emergence Φ Input
  1. * As for the FCM, the duration of one gonotrophic cycle is used as a unit of time. For convenience we use ‘cycles’ to refer to mosquito age and ‘periods’ to refer to the sequential time periods for which values are calculated in the PM.
