In this study, the harmful effect of Tuta absoluta on different tomato species was investigated. Six tomato genotypes which are Solanum chmielewskii (LA1028), Solanum neorickii (LA0247), Solanum hirsutum (LA777), Solanum pimpinellifolium (LA0722), and Solanum lycopersicum cv. Cuatomate and Solanum lycopersicum cv. Ailsa Craig (LA2838A) species were used as plant material in the study. To determine the incidence of Tuta absoluta on the plants, the egg and larvae were counted weekly by taking 5 leaves from the species. According to eggs and larvae counts, the plants were exposed to 5 types of severe damage while Solanum lycopersicum cv. Cuatomate was found to be later and less effective than the others. These results indicate that this species exhibits antixenosis properties against Tuta absoluta pests and that the other species that have been exposed to earlier and more severe damage lack such property.
