“…Release of herbivore-induced volatile organic compounds (VOCs) by plants has been shown to attract predators and parasitoids that may benefit the plants. At the same time, the VOCs may attract other herbivores, affect interactions between the plants and other mutualists such as, for example, pollinators, and affect neighboring plants (5,(7)(8)(9)(10). Plants may benefit more from particular predators or parasitoids of their herbivorous attacker than from others.…”

Plants are exposed to a suite of herbivorous attackers that often arrive sequentially. Herbivory affects interactions between the host plants and subsequently attacking herbivores. Moreover, plants may respond to herbivory by emitting volatile organic compounds (VOCs) that attract carnivorous natural enemies of the herbivores. However, information borne by VOCs is ubiquitous and may attract carnivores, such as parasitoids, that differ in their effectiveness at releasing the plant from its herbivorous attackers. Furthermore, the development of parasitoids within their herbivorous hosts, attacking a given host plant, may influence the elicitation of defensive reactions in the host plant. This may, in turn, affect the behavior of subsequent herbivores attacking the host plant. Here, we show that the species identity of a parasitoid had a more significant effect on defense responses of Brassica oleracea plants than the species identity of the herbivorous hosts of the parasitoids. Consequently, B. oleracea plants that were damaged by caterpillars (Pieris spp.) parasitized by different parasitoid species varied in the degree to which diamondback moths (Plutella xylostella) selected the plants for oviposition. Attracting parasitoids in general benefitted the plants by reducing diamondback moth colonization. However, the species of parasitoid that parasitized the herbivore significantly affected the magnitude of this benefit by its species-specific effect on herbivore-plant interactions mediated by caterpillar regurgitant. Our findings show that information-mediated indirect defense may lead to unpredictable consequences for plants when considering trait-mediated effects of parasitized caterpillars on the host plant and their consequences because of community-wide responses to induced plants.herbivore preference | induced gene transcription | parasitoid-dependent effect A cross their whole kingdom, plants have been found to interact with carnivorous arthropods that act to control herbivorous attackers of the plants. Such interactions between plants and carnivorous arthropods may ultimately increase fitness of the plants (1-3). Plant traits involved in such interactions include those that provide a predator/parasitoid with a resource such as, for example, food or shelter, or with information on the presence and abundance of herbivorous prey/hosts (4, 5). Although resource-and information-mediated indirect defenses of plants have long been collectively viewed within the context of ecological and evolutionary theory of indirect defenses, interactions between plants and carnivorous arthropods based on resource provisioning are distinctly different from those mediated by providing information (6). Whereas resource provisioning can be obligate and is often restricted to interactions with a limited number of carnivorous species, information emitted by herbivore-infested plants is generally ubiquitous, allowing all other organisms to respond to this information (5).

“…The ecophysiological functions of VOCs are not fully understood, but numerous compounds, above-and belowground, are related to signalling within plants, between plants, between plants and insects etc., their other very important role relating to antimicrobial defence mechanisms after wounding (e.g. Kesselmeier and Staudt 1999 and references therein, Dudareva et al 2004, Lucas-Barbosa et al 2011 and references therein, Schausberger et al 2012). In the atmosphere, VOCs are important contributors to chemical reactions related to the formation of tropospheric ozone (O 3 ) (Chameides et al 1992) and secondary organic aerosols (SOA) (e.g.…”

Terrestrial ecosystems, mainly plants, emit large amounts of volatile organic compounds (VOCs) into the atmosphere. In addition to plants, VOCs also have less-known sources, such as soil. VOCs are a very diverse group of reactive compounds, including terpenoids, alcohols, aldehydes and ketones. Due to their high reactivity, VOCs take part in chemical reactions in the atmosphere and thus also affect Earth's radiation balance.In this study, chamber and snow gradient techniques for measuring boreal soil and forest floor VOC fluxes were developed. Spatial and temporal variability in fluxes was studied with year-round measurements in the field and the sources of boreal soil VOCs in the laboratory with fungal isolates. Determination of the compounds was performed mass spectrometrically.This study reveals that VOCs from soil are emitted by living roots, above-and belowground litter and microbes. The strongest source appears to be litter, in which both plant residuals and decomposers play a role in the emissions. Temperature and moisture are the most critical physical factors driving VOC fluxes. Since the environment in boreal forests undergoes strong seasonal changes, the VOC flux strength of the forest floor varies markedly during the year, being highest in spring and autumn. The high spatial heterogeneity of the forest floor was also clearly visible in VOC fluxes. The fluxes of trace gases (CO 2 , CH 4 and N 2 O) from soil, which are also related to the soil biological activity and physical conditions, did not correlate with the VOC fluxes.Our results show that emissions of VOCs from the boreal forest floor accounts for as much as several tens of percent, depending on the season, of the total forest ecosystem VOC emissions. This can be utilized in air chemistry models, which are almost entirely lacking the below-canopy compartment.

“…Herbivorous insects are connected by both local and systemic plant-mediated interactions. Systemic effects may involve both roots and shoots (Soler et al, 2013) or leaves and flowers (Kessler et al, 2011;Lucas-Barbosa et al, 2011). We have focused on aboveground plant vegetative tissues because most information on community processes is available for insect communities associated with vegetative plant shoots.…”
