Tomato leaf miner Tutaabsoluta (Meyrick)(Lep: Gelechiidae) is one of the serious pests of tomato. In Europe, it was first detected in Spain in 2006 and afterward it rapidly spread to several countries becoming a key pest due to its behaviour and ecology. It was a quarantining pest for Iran up to 2010. It is detected for the first time in Urmiyeh in North- West of Iran in 2010 as well as identified in more than 20 regions of Iran up to June 2011. Current study carried out using at least 100 one-day old eggs under laboratory conditions (25±2°C, 65±5%RH and 16L:8D photoperiod)and aimed to determine daily mortality, survival rate, fecundity and life expectancy of different development stages ofT. absoluta, on two traditionally cultured tomato cultivars (ATABAY and CLUSE). Survival rate of larva, pupa,female and male was 0.90, 0.70, 0.17 and 0.29 respectively on ATABAY in contrast with 0.86, 0.65, 0.13 and 0.24on CLUSE cultivar. Life expectancy in first days of experiment was 26.45 and 23.79 on ATABAY and CLUSE cultivars respectively. Mean fecundity, mean adult female's pre-oviposition period (APOP)and mean total preoviposition period (TPOP) obtained92.13±7.80,0.33±0.12 and 21.47±0.43 respectively on ATABAY cultivar in contrast with 77.18±6.44, 0.18±0.12 and 20.64±0.52on CLUSE.These results indicated that CLUSE cultivar influenced herbivore life table parameters more negatively than ATABAY cultivar as well as it could considered asrelatively resistant host for T.absoluta.
