Host plant genotype determines bottom-up effects in an aphid-parasitoid-predator system
Plant genotypes are known to affect performance of insect herbivores and the community structure of both herbivores and higher trophic levels. Still, only a limited number of studies demonstrate differences in the performance of predators and parasitoids because of plant genotypic effects and most of these focus on gall formers. We designed a greenhouse experiment to investigate the effects of ...
متن کاملMisidentification of tansy, Tanacetum macrophyllum, as yarrow, Achillea grandifolia: a health risk or benefit?
Tansy, Tanacetum macrophyllum (Waldst. & Kit.) Sch. Bip., is often misidentified by herb collectors as yarrow, Achillea grandifolia Friv. With the former, cases of poisoning induced by its ingestion are well documented, but the latter is widely used for ethnopharmacological purposes. The aim of this study was to estimate, based on the volatile metabolite profiles of the two species, the potenti...

متن کاملVariation in volatile compounds from tansy (Tanacetum vulgare L.) related to genetic and morphological differences of genotypes.
Air-dried flower heads of 20 Finnish tansy genotypes were extracted with petroleum ether and analyzed using GC-MS. A total of 55 volatile compounds were detected, and 53 were identified. Of the tansy genotypes studied, 15 were well defined and five were mixed chemotypes. Complete linkage analysis differentiated the populations into six clusters. The most frequently found monoterpene was camphor...
