Tomato leaf miner, Tuta absoluta, is the most destructive pest of tomato in Iran. Resistance levels of six tomato cultivars to the pest damage were evaluated during two tomato growing seasons (2014-2015). Samplings were done weekly. Leaf and fruit damages as well as the total yield of the cultivars were compared. Furthermore, leaf trichome density was evaluated. The highest to lowest leaf infestation rates were recorded for the Primo early, CaljN3, Petomek, Rio grande, Early urbana and Super 2270 cultivars respectively. Fruit infestation rate in Early urbana was significantly lower than the other cultivars in both growing seasons. Total yield of tomato (from the highest to the lowest) belonged to Super 2270, Early urbana, Rio grande, Petomek, Calj N3 and Primo early cultivars.
