[Abstract] Plants respond to herbivory with diverse defence responses (Schoonhoven et al., 2005). Many herbivorous insects deposit their eggs on their host plants before their larvae start to feed. Thus, plants could use insect eggs as a signal to increase their resistance to herbivores. Here, we report experimental procedures to explore whether and how insect oviposition impacts on plant resistance against the feeding larvae. The described approach revealed that Nicotiana attenuata (N. attenuata) plants that were previously exposed to oviposition by lepidopteran moths respond to herbivory by generalist Spodoptera exigua (S. exigua) and specialist Manduca sexta (M. sexta) larvae with an increased induction of defence responses, which ...
[摘要] 植物对具有不同防御反应的食草有反应（Schoonhoven等人，2005）。许多食草昆虫在它们的幼虫开始喂食之前将它们的卵沉积在它们的寄主植物上。因此，植物可以使用昆虫卵作为信号来增加它们对食草动物的抗性。在这里，我们报告实验程序，以探究是否和如何昆虫产卵影响植物抵抗喂养幼虫。所描述的方法揭示了先前暴露于鳞翅目蛾产卵的烟草（Nicotiana attenuata）（ N。attenuata ）植物通过万古霉属（Spodoptera exigua） （ S.exigua ）和专家 （ sexta ）幼虫与防御反应的诱导增加，或幼虫的免疫状态（Bandoly等人，2015; Bandoly等人，2016）。因此，昆虫产卵可以引发进食诱导的植物防御（引发：根据先前刺激的经验增强的植物对胁迫的反应; Hilker等人，2015）。使用用于昆虫产卵和幼虫食草的标准化程序的全因子实验允许破译植物暴露于昆虫卵对幼虫性能，进食损伤和免疫状态的影响以及区分卵诱导的植物对卵发生反应的响应到幼虫喂养。
