We evaluated the effects of two classes of phenols on performance of penultimate instar southern armyworms, Spodoptera eridania. One class consisted of phenols containing a catechol (ortho-dihydroxybenzene) moiety and included chlorogenic acid, quercetin, rutin, and rhamnetin. A second group consisted of the phenolic glycoside salicin and its derivatives salicortin and tremulacin. The compounds were painted onto lima bean (Phaseolus lunatus) leaves and fed to larvae for the duration of the fifth instar. Chlorogenic acid and rhamnetin had no deleterious effects; rutin and quercetin caused some mortality and rutin reduced growth rates by decreasing consumption and digestion efficiency. Results showed that ortho-dihydroxybenzene groups may be necessary, but are not sufficient for biological activity. Salicin did not affect larvae; salicortin and tremulacin reduced growth rates primarily by decreasing consumption. These two compounds also caused degenerative lesions in midgut tissues. The presence of a benzoyl ester group in tremulacin accentuates its toxicity, relative to that of salicortin.
我们评估了两类酚类物质对末龄前南方黏虫（草地贪夜蛾）生长性能的影响。一类是含有儿茶酚（邻二羟基苯）部分的酚类物质，包括绿原酸、槲皮素、芦丁和鼠李素。另一类是酚糖苷水杨苷及其衍生物水杨苷配基和震颤素。将这些化合物涂抹在利马豆（菜豆）叶片上，并在五龄幼虫期喂给它们。绿原酸和鼠李素没有有害影响；芦丁和槲皮素导致了一些死亡，并且芦丁通过降低摄食量和消化效率降低了生长速率。结果表明，邻二羟基苯基团可能是必需的，但对于生物活性来说并不充分。水杨苷对幼虫没有影响；水杨苷配基和震颤素主要通过降低摄食量降低生长速率。这两种化合物还导致中肠组织出现退行性病变。相对于水杨苷配基，震颤素中苯甲酰酯基团的存在加剧了其毒性。
