Abstract

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is the major pest of tomato plant and causes damage on its leaves, buds, flowers, branches and fruits. The aim of the present study was to evaluate the damage caused by Tuta absoluta on different cultivars of tomato under greenhouse condition. Eleven cultivars were tested in four replications. The evaluation was carried out on 45 days-old plants regard to their vegetation characteristics and damage attributes. Sizes of mines on the damaged tissues were considered as the main character of damage, classified into four different groups and compared using cluster analysis. Analysis of data and mean comparison were accomplished using GLM procedure (SAS software) and Duncan test (P< 0.5) respectively, while the cluster analysis and pairwise mean comparison for damaged distal buds were carried out using Kruskal-Wallis Test (SPSS software). Analysis resulted in grouping the examined cultivars into four categories including relatively resistant cultivars (Atabay, Cluse, Servant), midresistant cultivars (Yagmur, Kubra, Super Strain B), mid susceptible cultivars (Milas, Iraz, Prenses, Hazarcentetis) and susceptible cultivar (Y-32-227).
