植物产生多种次生代谢物(PSM)，可能对食草动物具有选择性。然而，专业食草动物可能会使用PSM作为识别宿主、产卵和刺激摄食的线索，或者用来防御寄生虫和捕食者。这概括了PSM的双重角色：既威慑通才，又吸引专家。目前尚不清楚专业食草动物是否是PSM多样性进化中的一股选择性力量。这种选择性力量的一个先决条件是，专家的偏好和/或业绩受到私营军种管理的影响。为了研究这些问题，我们用朱砂蛾(Tyria Jacobaeae)和雅可布和水产雅可布人工杂交科的植物进行了产卵试验。朱砂蛾是普通朱砂蛾的一种特殊食草动物，适应于吡咯里西丁生物碱(PAS)，即这些植物的防御性PSM。成虫的产卵量和产卵批次取决于植株的基因型，并与类雅可宾的叔胺和某些类土豆烯类多胺的浓度呈正相关。其他PAS与产卵偏好不相关。
Plants produce a variety of secondary metabolites (PSMs) that may be selective against herbivores. Yet, specialist herbivores may use PSMs as cues for host recognition, oviposition, and feeding stimulation, or for their own defense against parasites and predators. This summarizes a dual role of PSMs: deter generalists but attract specialists. It is not clear yet whether specialist herbivores are a selective force in the evolution of PSM diversity. A prerequisite for such a selective force would be that the preference and/or performance of specialists is influenced by PSMs. To investigate these questions, we conducted an oviposition experiment with cinnabar moths (Tyria jacobaeae) and plants from an artificial hybrid family of Jacobaea vulgaris and Jacobaea aquatica. The cinnabar moth is a specialist herbivore of J. vulgaris and is adapted to pyrrolizidine alkaloids (PAs), defensive PSMs of these plants. The number of eggs and egg batches oviposited by the moths were dependent on plant genotype and positively correlated to concentrations of tertiary amines of jacobine-like PAs and some otosenine-like PAs. The other PAs did not correlate with oviposition preference.
