Effects of Abiotic Factors on HIPV-Mediated Interactions between Plants and Parasitoids

Table 2

Herbivore-induced plant volatiles emitted constitutively but in increasing concentrations after herbivore attack (quantitative changes) or only after herbivore attack (qualitative changes). Compounds from both categories can have very similar structures and share a biosynthetic pathway (see Table 1). This list is non-exclusive and inter-specific variation can be expected. It is mainly based on results on potato and tobacco (Solanum tuberosum and Nicotiana tabacum) reported by Dickens [148] and Robert et al. [46] as well as several review articles [16, 20, 147].
