Trophic cascades initiated by fungal plant endosymbionts impair reproductive performance of parasitoids in the second generation

Abstract: Trophic cascades initiated by fungal plant endosymbionts impair reproductive performance of parasitoids in the second generation Variation in plant quality can transmit up the food chain and may aVect herbivores and their antagonists in the same direction. Fungal endosymbionts of grasses change the resource quality by producing toxins. We used an aphid-parasitoid model system to explore how endophyte eVects cascade up the food chain and inXuence individual parasitoid performance. We show that the presence of … Show more

“…Aphids are good model organisms to study multi-trophic interactions (Härri et al 2008). Many aphid species are serious crop pests that cause damage by feeding on plant sap or act as vectors of virus diseases (Van Emden and Harrington 2007).…”

“…For instance, changes in phloem sap composition can affect organisms that feed upon these plants including sap-feeding aphids [3]. In an aphid -parasitoid -hyperparasitoid food web, the effects of host plant traits can cascade up as far as the fourth trophic level [2], even when there are no effects on the herbivores [4].…”

“…These effects include, e.g., decrease in population density [10], lowered body mass [11], increased toxicity-induced mortality [12] and suppression of reproduction and growth [13]. The alkaloids produced by endophytes may also have negative effects on the natural enemies of invertebrate herbivores [14], [15]. However, experimental studies on endophytes and their effects on higher trophic levels are still scarce [2], [16], and no study has examined the cascading effects of fungal symbionts of grasses on vertebrate food chains.…”
