Life table parameters of the tomato leaf miner Tuta absoluta (Lepidoptera: Gelechiidae) on different tomato cultivars
Journal of Applied Entomology 141 (1-2), 88-96
Abstract: The tomato leaf miner Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a devastating pest of tomato plants originating from South America. In this study, the effect of three tomato cultivars on the life table parameters of T. absoluta was investigated. Data were analysed based on age-stage, two-sex life table theory. The net reproduction rate (R0) of T. absoluta on Falkato, Isabella and Grandella cultivars was determined as 15.73 ± 3.35, 17.66 ± 3.33 and 10.03 ± 4.10 eggs, respectively. The intrinsic rate of increase (r) value on those cultivars was 0.09 ± 0.007, 0.095 ± 0.006 and 0.074 ± 0.017 day-1, respectively. Finite population rates of increase (λ) were 1.095 ± 0.008, 1.099 ± 0.007 and 1.076 ± 0.018 day-1, and mean generation times (T) on the three cultivars were 30.09 ± 0.29, 30.22 ± 0.27 and 31.12 ± 0.65 days, respectively. The egg incubation period, pre-adult duration and fecundity on these tomato cultivars was also calculated. The results showed no significant differences between r, R0, and T on the three tested tomato cultivars. These findings can be useful for developing an integrated pest management strategy against this noxious pest.
