The influence of host plant on population dynamics of an invasive pest, Tuta absoluta was studied on three economically important solanaceous crops. Experiments were conducted in laboratory (29 ± 0.5°C, 75 ± 5% RH and a photoperiod of 14:10 hr [L:D]) using tomato ( Solanum lycopersicum L.), potato ( Solanum tuberosum L.) and eggplant ( Solanum melongena L.). Results indicated that intrinsic rate of increase ( r ), finite rate of increase ( λ ) and net reproductive rate ( R 0 ) were higher, and mean generation time ( T ) was the shortest on tomato. Results suggested that T. absoluta developed on all the three plants, and tomato plant was most preferred one. Results suggested that T. absoluta has a potential to become a serious pest on potato and even on eggplant under favourable conditions. We used the life tables of 0.025th and 0.975th percentiles of bootstraps to project the uncertainty of population growth, a new concept.
