Comparison of adult longevity, fecundity, net reproductive rate and intrinsic growth rate among the resistant, susceptible and Kisumu colonies.
Colony/strain | Mean ± SD | |||
---|---|---|---|---|
Longivity (days) | R0 | r | Fecundity | |
Resistant | 39.7 ± 1.6a | 2.6 ± 0.3a | 0.215 ± 0.007a | 4.31 ± 0.9a |
Susceptible | 29.9 ± 1.7b | 4.7 ± 0.6b | 0. 285 ± 0.010b | 8.6 ± 1.0b |
Kisumu | 29.6 ± 1.1b | 4.1 ± 0.2b | 0.241 ± 0.013b | 9.7 ± 0.1b |
Fecundity is measured in number of female progeny per female per day.
R0—is the mean net replacement rate (number of offspring per female per generation).
r—is intrinsic per-capita growth rate (number of offspring per female per day).
*Mean and standard deviations of fecundity, net reproductive rate intrinsic per-capita growth rate and survival time. The same superscript letters indicate no significant difference.
