我们研究了一组四种生物合成相关环烯醚萜苷，桃红素，梓醇，马齿苋苷和曲霉苷，对一种通才，Lymantria dispar (lymantriae)，舞毒蛾和一种适应的专家，七叶树，Junonia coenia（蛱蝶科）的幼虫的影响。总的来说，与不含环烯醚萜苷的对照饲料相比，在含环烯醚萜苷的人工饲料中，水蛭的生长和存活情况明显较差。在选择试验中，先前暴露于含有环烯醚萜苷的饮食导致幼虫随后更喜欢含有环烯醚萜苷的饮食，即使它们对生长和生存有害。与此相反，在含有桃红素和梓醇两种环烯醚萜苷的饲粮中，coenia幼虫的生长和成活率优于不添加环烯醚萜苷或添加longanin和asperuloside的饲粮。添加和不添加环烯醚萜苷日粮的选择试验结果以及添加不同环烯醚萜苷日粮之间的选择试验结果也反映了这些差异。这些结果从以下几个方面进行了讨论：(1)多面手和专门手对植物化感物质含量质的变化的反应差异；(2)诱导取食偏好；(3)作为植物防御手段的质的化感化学变异的进化。
We examined the effects of a set of four biosynthetically related iridoid glycosides, aucubin, catalpol, loganin, and asperuloside, on larvae of a generalist, Lymantria dispar (Lymantriidae), the gypsy moth, and an adapted specialist, the buckeye, Junonia coenia (Nymphalidae). In general, L. dispar grew and survived significantly less well on artificial diets containing iridoid glycoside, compared to a control diet without iridoid glycosides. In choice tests, previous exposure to a diet containing iridoid glycosides caused larvae subsequently to prefer iridoid glycoside-containing diets even though they were detrimental to growth and survival. In contrast, J. coenia larvae grew and survived better on diets with aucubin and catalpol, the two iridoid glycosides found in the host plant Plantago lanceolata (Plantaginaceae), than on diets with no iridoid glycoside or with longanin and asperuloside. The results of choice tests of diets with and without iridoid glycosides and between diets with different iridoid glycosides reflected these differences as well. These results are discussed in terms of (1) differences between generalists and specialists in their response to qualitative variation in plant allelochemical content, (2) the induction of feeding preferences, and (3) the evolution of qualitative allelochemical variation as a plant defense.
