The resistance of 11 tomato cultivars (Ps-6515, Berlina, Poolad, Petoprid-5, Zaman, Matin, Golsar, Sandokan-F1, Golshan-616, Sadeen-95 and Sadeen-21) to the tomato moth, Tuta absoluta (Meyrick) (Lepidoptera:Gelechiidae) was investigated under field conditions. A randomized complete block design was used with three replications. Data analysis indicated that there were significant differences (P < 0.05) among cultivars regarding leaflet damage, leaf damage, overall plant damage, number of mines per leaf, number of holes on the stem, and fruit. Our findings revealed that the cultivars Berlina, Golsar, Poolad, and Zaman were less suitable cultivars, suggesting that they are more resistant to the tomato moth than the other cultivars. The high density of leaf trichomes present in the cultivars Berlina, Zaman, and Golsar can be one of the possible causes of resistance to T. absoluta. Knowledge of the extent of susceptibility or resistance of cultivars to a pest on a crop is one of the fundamental components of integrated pest management (IPM) programs for any crop.
在田间条件下，对11个番茄品种（Ps-6515、柏林娜、普拉德、佩托普里德-5、扎曼、马丁、戈尔萨尔、桑多坎-F1、戈尔山-616、萨丁-95和萨丁-21）对番茄潜叶蛾（Tuta absoluta (Meyrick)，鳞翅目：麦蛾科）的抗性进行了研究。采用随机完全区组设计，重复3次。数据分析表明，各品种在小叶损伤、叶片损伤、整株损伤、每片叶的虫道数、茎上的孔洞数和果实方面存在显著差异（P < 0.05）。我们的研究结果表明，柏林娜、戈尔萨尔、普拉德和扎曼品种不太适合种植，这表明它们比其他品种更抗番茄潜叶蛾。柏林娜、扎曼和戈尔萨尔品种中存在的高密度叶毛可能是对番茄潜叶蛾产生抗性的可能原因之一。了解品种对作物害虫的感病性或抗性程度是任何作物综合害虫管理（IPM）计划的基本组成部分之一。
