“…Overall, at least 31 different pure chemotypes (categorised by the main terpene only) of T. vulgare have been described for Europe (Tétényi et al 1975;Abad et al 1995;Rohloff et al 2004;Dragland et al 2005;Judzentiene and Mockute 2005). In studies by country, 26 chemotypes were described for Hungary (440 samples from 88 different localities) (Tétényi et al 1975) and 10 chemotypes for Finland (527 samples from 180 different localities) (Holopainen et al 1987a). Other country-wide investigations (sample size between 20 and 40) found only four to seven chemotypes (Keskitalo et al 2001;Rohloff et al 2004;Judzentiene and Mockute 2005).…”

Intraspecific plant chemical diversity and its relation to herbivory

Several aromatic plant species are well known for their high intraspecific variation in terpene composition. Within these species, different chemotypes can be distinguished, which are characterised by one major metabolite and distinct satellite compounds in lower abundance. Such intraspecific differences in plant quality should have major effects on herbivorous insects but may also be partly shaped by their feeding activities. In the present study, the effects of selected Tanacetum vulgare L. chemotypes on herbivore presence and preferences were investigated, and the naturally occurring diversity of T. vulgare was explored at a small spatial scale. A distinct distribution pattern of aphids and miners was found on different chemotypes of different origin of T. vulgare, with species-specific preferences of different herbivorous species. Larvae of two generalist noctuid species performed worse on most chemotypes of T. vulgare than on other plant species. Furthermore, the specific terpene composition of T. vulgare influenced larval development of these two generalist species. The naturally occurring chemical diversity of T. vulgare plants in an area smaller than 3 km(2) was extremely high, exhibiting 14 different chemotypes. Several individual patches of T. vulgare consisted of more than one chemotype. In conclusion, the existing chemotypical pattern of T. vulgare plants leads to a species-specific distribution of herbivores but may in turn be the result of contrasting selection pressures of various specialist and generalist herbivores.

“…Tansy is widely distributed throughout Europe and Asia (Holopainen et al ., , b; Holopainen, ), preferring disturbed, well‐drained, poor soils. Single plants comprise a ‘genetically identical’ genet with up to 50 flowering ramets (shoots) (Mitich, ; Massonnet, ).…”

“…This has led to the designation of chemotypes based on the dominant compound in the chemical profile (Holopainen, ; Wolf et al ., ). Breeding experiments and studies using molecular markers have shown that essential oil composition of tansy has a genetic basis (Holopainen et al ., ; Holopainen, Hiltunen & von Schantz, ; Holopainen, ; Keskitalo, Pehu & Simon, ).…”

Field assessments and genetic analyses on tansy aphid, Metopeurum fuscoviride Stroyan were made aiming to investigate whether a specialist aphid species and its associated predator density differ between chemotypes of the plant host, tansy, and whether the essential oil composition of the plant host determines the genetic differences observed between colonies of M. fuscoviride inhabiting these different chemotypes. Tansy plants were defined after volatile extractions as Camphor Pure and Borneol Pure, respectively, with hybrid chemotypes defined as Camphor Hybrid, Borneol Hybrid, and Thujone Hybrid, respectively. Ladybird beetles, Coccinella septempunctata (L.), clearly dominated Pure Camphor plants, whereas significantly higher numbers of the nursery web spider, Pisaura mirabilis (Clerck), were detected on Borneol Pure and Borneol Hybrid plants. Genetic analyses using five polymorphic microsatellite markers revealed that higher genetic similarity existed between M. fuscoviride aphids from Borneol Pure and Borneol Hybrid plants and between Camphor Pure and Camphor Hybrid plants, respectively, whereas a lower level of genetic similarity was seen between these aphids from Thujone Hybrid plants. Accordingly, it is possible that host plant‐adapted species can create much context‐dependency in the nature and strength of predation effects, which may in turn alter costs and benefits of host plant chemical differentiations, or even the prey genotype variations. © 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 114, 709–719.

“…Herein, we carried out a manipulation experiment that allowed us to explore how and to what extent direct and indirect bottom-up and top-down forces affect the aphid populations on tansy plants. While tansy terpenoid production (chemical volatiles), and thus also differences between chemotypes, has a genetic basis (i.e., different genotypes express different chemical phenotypes; Holopainen, Hiltunen, Lokki, Forsén, & Schantz, 1987), all our hypotheses are based on differences regarding variation in the plant's volatile chemical profile.…”

Additive effects of plant chemotype, mutualistic ants and predators on aphid performance and survival

et al. 2018

Cascading effects in ecological systems acting across three or more trophic levels can be either of a resource‐based (bottom‐up) or natural enemy‐based (top‐down) nature. But, due to their complexity, these effects are often considered separately and their relative strength, acting simultaneously, remains unknown. In a semi‐natural field experiment using tansy (Tanacetum vulgare L.) and the specialised tansy‐aphid Metopeurum fuscoviride Stroyan as a model system, we compared the effects of four distinct plant chemotypes (i.e., bottom‐up), defined by the bouquet of their volatile terpenoids, on aphid population dynamics by manipulating the presence/absence of mutualistic ants and presence/absence of naturally occurring predators (i.e., top‐down). Predators reduced aphid abundance and colony survival but did not reduce initial growth rate due to a time‐lag until predators arrived on the plants. Ants directly benefited initial aphid growth rates and abundance, even in the absence of predators, but not the number of days an aphid colony persisted on the plant. Plant chemotype directly affected aphid growth rate and final abundances across the different plants and indirectly affected the abundances of tending ants and predators through effects on aphids. We found that tending ants were more abundant on one plant chemotype. Although ant abundance did not affect aphid population development, it became clear that ants had a preference towards aphids on certain chemotypes. However, a higher number of predators led to a lower number of aphids. The results confirm the importance of plant chemical variation, acting through multiple effects on many species in arthropod communities, and support results from field studies. In a natural population, with a diverse selection of host‐plant variants, aphid populations and their interacting species can therefore be structured at the level of an individual plant. Specialist aphids on patchily distributed host plants can exhibit metacommunity dynamics at very local scales. Plant within‐species variation within a local population is often ignored in metacommunity ecology, yet our work shows that this can have strong effects on insect–ant–natural enemy dynamics, and therefore, future research should incorporate this into current theory and experimental studies.
