A variety of plant secondary compounds, several of which are quite widespread in nature were tested for their deterrence to the generalist grasshopperSchistocerca americana in short-term behavioral assays. The compounds were coumarin, salicin, tannic acid, gramine, nicotine, quinine, carvone, geraniol, abietic acid, umbelliferone, and ursolic acid. These were then tested for their post-ingestional effects over the whole of the last larval instar. Different methods were employed to mask the taste of compounds that were deterrent in order to ensure that any effects were not due to reduced feeding. In no case was there any indication of a detrimental effect or any trend suggesting one. In two cases, there was a significant increase in growth rate with the addition of the secondary compound to the diet. The evolutionary implications of these findings are discussed.
多种植物次生化合物，其中有几种在自然界中相当普遍，被测试其对普通蚱蜢 Schistocerca americana 的短期行为抑制作用。这些化合物包括香豆素、水杨醇、鞣酸、禾草、尼古丁、奎宁、香芹酮、香叶醇、松香酸、伞形酮和熊果酸。然后，它们被测试在整个最后一个幼虫龄期的摄食后效应。为了确保任何影响都不是由于摄食量减少而产生的，采用了不同的方法来掩盖有抑制作用的化合物的味道。在任何情况下，都没有任何有害影响的迹象或任何趋势表明有影响。在两种情况下，在饮食中添加次生化合物会显著提高生长速度。讨论了这些发现的进化意义。
