番茄潜叶蛾是近年来传入甘肃省的具有重大危害性的入侵害虫。通过探究不同番茄品种对番茄潜叶蛾的抗虫性差异，筛选抗性基因，为番茄潜叶蛾的综合治理、番茄的抗性育种提供科学的参考依据。在田间封闭式大棚内将14个番茄品种按正交拉丁方Ⅰ排列法进行种植，待番茄植株发育至生长拔节期在大棚内均匀放置番茄潜叶蛾的成虫和蛹进行人工自然感虫，调查番茄潜叶蛾在不同番茄品种上的自然为害情况。结果表明，14个番茄品种中，樱桃番茄品种秦番小皇后和秦蔬仙子对番茄潜叶蛾表现出一定的抗性(R)，虫情指数均低于25％，蛀果率均低于20%，其余品种抗虫能力均较弱，表现为感虫(S)或高感(HS)。

Tomato leaf miner[Tuta absoluta(Meyrick)] was invasive pest of great harm introduced into Gansu Province in recent years. In order to explore the differences in insect resistance of different tomato cultivars to Tuta absoluta (Meyrick) and screen resistance genes, 14 tomato varieties were planted in closed greenhouses in the field according to the orthogonal Latin square I. When tomato plants developed to the growth stage, adults and pupae of Tuta absoluta were evenly placed in the greenhouse for artificial natural insect infection, then to investigate the damage of Tuta absoluta in different varieties. Results showed that only Xiaohuanghou and Qinshuxianzi both showed some resistance(R) to Tuta absoluta, their pest damage indexes were lower than 25%, their fruit-boring rates were lower than 20%, the pest resistances of other tomato varieties were weak, and all of them showed susceptibility (S) or high susceptibility (HS).
