Abstract Cataclysta lemnata Linnaeus, 1758 is a semi-aquatic moth that feeds on Lemnaceae and few of other aquatic plants. In recent years, this moth has been seen feeding on Azolla Lamarck, 1783 in Iran in high numbers. The effect of the host plant on preference and performance of the moth was assessed under laboratory conditions. Despite the high survival rate of the young larvae, due to high mortality of the late instars and pupa on Lemna Linnaeus, 1753, the total survival rate on Azolla was higher. Feeding on Azolla increased the development time by almost a week and reduced fertility to half. However, by consuming more food, regulating the egg laying dynamic, and increasing emergence period, the moth retrieved most of the losses and adapted to feed on Azolla. A week before pupation, feeding activity increased between 2 and 8 times in all treatments and on Azolla, the larvae growth rate was slightly higher.

Cataclysta lemnata Linnaeus, 1758 (Lepidoptera: Crambidae) 扩大其寄主范围，以入侵水生蕨类植物为食，Azolla Lamarck 种类，1783 (Hydropteridales: Azollaceae)：适应因素和成本

摘要 Cataclysta lemnata Linnaeus, 1758 是一种半水生飞蛾，以 Lemnaceae 和少数其他水生植物为食。近年来，这种飞蛾在伊朗的 1783 年被大量食用。在实验室条件下评估寄主植物对蛾的偏好和性能的影响。尽管幼虫的成活率很高，但由于1753年Lemna Linnaeus上晚龄和蛹的高死亡率，因此满江红的总成活率较高。以 Azolla 为食使发育时间增加了近一周，并将生育率降低了一半。然而，通过消耗更多的食物、调节产卵动态和增加羽化期，飞蛾恢复了大部分损失并适应以红萍为食。化蛹前一周，
