- Life tables were constructed for the tobacco aphid, Myzus nicotianae Blackman, in the laboratory using three varieties of burley tobacco commercially available in Kentucky. Daily mortality and fecundity schedules were established to estimate net reproductive rate and instantaneous rate of population increase on each variety. The number of days to first reproduction, longevity, mortality, and fecundity were similar on each variety. Net reproductive rate, instantaneous rate of population increase, mean generation time, and doubling time of the populations were the same for each variety, indicating that population growth of the aphid on the three varieties did not differ significantly.
