Variable or Parameter | Symbol | Comments and Constraints |
---|---|---|
Time, measured in whole units equal to average length of sporogonic cycle, from infection of mosquito by malaria to cycle from which mosquito gives infectious bites | D | input 0< D |
Number of age classes included in analysis | λ |  |
Cycle number (identifies specific cycle in the λ cycles over which probabilities are tracked in the FCM) | i | 0≤ i ≤λ |
Malaria status, the number of whole or partial cycles since infection with malaria | m | 0≤ m ≤λ, m = 0 means not infected |
Biopesticide infection status, the number of whole or partial cycles since infection with biopesticide | l | 0≤ l≤ λ, l = 0 means not infected |
Average number of eggs laid in cycle i by mosquitoes surviving to the start of cycle i | F i | Â |
Average lifetime number of eggs laid per mosquito | φ |  |
Average number of eggs laid in cycle i, by mosquitoes starting cycle i with malaria status m and biopesticide status l | f i,m,l | m<i l<i |
Average probability of survival from start of cycle i to start of cycle i+1 | S i | Â |
Average probability that a mosquito starting cycle i with malaria status m and biopesticide status l, will survive to start of cycle i+1 | s i,m,l | m<i l<i |
Average probability of a mosquito being alive at start of cycle i. | V i | Â |
Average probability of a mosquito being alive, with malaria status m and biopesticide status l, at start of period i. | v i,m,l | m<i l<i |
Probability that a mosquito alive at start of cycle i with malaria status m and biopesticide status l, survives and bites host type h in cycle i | q i,m,l,h | m<i l<i |
Type of host attacked | h | h=1, non-human |
 |  | h=2, non-infectious human |
 |  | h=3, infectious human |
Average number of infectious bites in cycle i per mosquito alive at the start of cycle i | I i | Â |
Average lifetime number of infectious bites per mosquito | u | Â |
