Debate still continues around the definition of generalism and specialism in nature. To
some, generalism is equated solely with polyphagy, but this cannot be readily divorced from …

All organisms experience fundamental conflicts between divergent metabolic processes. In
plants, a pivotal conflict occurs between allocation to growth, which accelerates resource …

Some plant species express an extraordinarily high intraspecific diversity in phytochemicals
(= chemodiversity). As discussed for biodiversity, higher chemodiversity may provide better …

Chemodiversity, the diversity of specialised (secondary) metabolites, plays a crucial role in
mediating interactions between plants and animals, including insect herbivores and …

Biodiversity in ecosystems is crucial in providing ecosystem services and their stability and
resilience. However, most studies supporting the benefits of biodiversity in crop health were …

It is well known that plant volatiles influence herbivores in their selection of a host plant;
however, less is known about how the nonvolatile metabolome affects herbivore host …

Tansy plants (Tanacetum vulgare L.) exhibit high chemical variation, particularly in mono-
and sesquiterpenes that are stored in specialised glands on the plant surface. In the present …

Plant chemistry is one of the main drivers of herbivore distribution. Monophagous herbivore
species are highly specialized, but even within their only host species the chemistry varies …

Plants of the same species can strongly differ in their specialized metabolite profiles, which
can affect insect presence and abundance in the field. However, how specialized chemistry …

Intraspecific and intra-individual differences in emitted volatile compounds and in surface
and phloem sap-related metabolites do not only affect host plant choice of monophagous …
