“…Preferences are shown, however, when one of the plants is attacked by both host and non‐host herbivores, which is common in nature (Shiojiri et al ., ; Vos et al ., ; Soler et al ., ; Bukovinszky et al ., ; Kruidhof et al ., ; Soler et al ., ; Ponzio et al ., ; Chabaane et al ., ). We show that parasitoid preferences for dually attacked plants are affected by the density of non‐host herbivores (Zhang et al ., ; Yamamoto et al ., ). However, this contrasts with Ponzio et al .…”

“…Several non‐host herbivore features can play a role in affecting the interaction between parasitoid and host, e.g. feeding guild (Rodriguez‐Saona et al ., ; Soler et al ., ; Zhang et al ., ; De Rijk et al ., ), origin (Desurmont et al ., ; Chabaane et al ., ), and feeding location (De Rijk et al ., ) of the non‐host herbivores, the diversity of the non‐host species (Vos et al ., ) and possibly also the density of the non‐host herbivores (Kratina et al ., ; Zhang et al ., ; Yamamoto et al ., ; Ponzio et al ., ). An increase in non‐host herbivore density may mask host presence in the two phases of parasitoid foraging.…”

Abstract. 1. Foraging decisions of parasitoids are influenced by host density via density-mediated indirect interactions. However, in the parasitoid's environment, non-suitable herbivores are also present. These non-hosts also occur in different densities, which can affect a parasitoid's foraging behaviour.2. The influence of non-host densities can be expressed during the first phase of the foraging process, when parasitoids use plant volatiles to locate plants infested by their host. They may also play a role during the second phase, when parasitoids use infochemicals from the host and plant to locate, recognise and accept the host.3. By using laboratory and field setups, it was studied whether the density of non-host herbivores influences these two phases of the foraging behaviour of the parasitoid Cotesia glomerata as well as the parasitoid's efficiency to find its host, Pieris brassicae caterpillars.4. The findings show that a high non-host density, regardless of the species used, negatively affected parasitoid preference for host-infested plants, but that the behaviour on the plant and the total host-finding efficiency of the parasitoids were not influenced by non-host density.5. These results are discussed in the context of density-mediated indirect interactions.

Plant volatiles mediate tritrophic interactions between plants, herbivorous arthropods and the carnivorous natural enemies of herbivores in various ways. These volatiles are classified into two categories: herbivore‐induced plant volatiles (HIPVs) and constitutively emitted plant volatiles. Herbivores and carnivores use these plant volatiles as information for effective foraging. Consequently, infochemical webs based on the multifunctional aspects of HIPVs can be constructed. This article reviews the ecological function of plant volatiles in a single tritrophic system and the effects of the coupling of two tritrophic systems on the function of plant volatiles with emphasis on the infochemical webs in tritrophic systems. Furthermore, prospects for the application of HIPVs that attract specific natural enemies are discussed. Key Concepts: In response to herbivore‐induced damage, plants emit the so‐called ‘herbivore‐induced plant volatiles (HIPVs)’ that are not naturally emitted from plants or in many cases emitted only in trace amounts. The mixtures of HIPVs vary according to the type of plants: herbivores and carnivores. Both HIPVs and constitutively emitted plant volatiles are separately and/or simultaneously used by both herbivores and carnivores to form infochemical webs. Coupling the two tritrophic systems on the same plants affects the infochemical webs of each tritrophic system either positively or negatively. HIPVs would be a new tool for biological control. This requires comprehensive studies on the target agroecosystem.
