Chemical information influences the behaviour of many animals, thus affecting species interactions. Many animals forage for resources that are heterogeneously distributed in space and time, and have evolved foraging behaviour that utilizes information related to these resources. Herbivoreâinduced plant volatiles (HIPVs), emitted by plants upon herbivore attack, provide information on herbivory to various animal species, including parasitoids. Little is known about the spatial scale at which plants attract parasitoids via HIPVs under field conditions and how intraspecific variation in HIPV emission affects this spatial scale. Here, we investigated the spatial scale of parasitoid attraction to two cabbage accessions that differ in relative preference of the parasitoid Cotesia glomerata when plants were damaged by Pieris brassicae caterpillars. Parasitoids were released in a field experiment with plants at distances of up to 60 m from the release site using intervals between plants of 10 or 20 m to assess parasitism rates over time and distance. Additionally, we observed hostâlocation behaviour of parasitoids in detail in a semiâfield tent experiment with plant spacing up to 8 m. Plant accession strongly affected successful host location in field setâups with 10 or 20 m intervals between plants. In the semiâfield setâup, plant finding success by parasitoids decreased with increasing plant spacing, differed between plant accessions, and was higher for hostâinfested plants than for uninfested plants. We demonstrate that parasitoids can be attracted to herbivoreâinfested plants over large distances (10 m or 20 m) in the field, and that stronger plant attractiveness via HIPVs increases this distance (up to at least 20 m). Our study indicates that variation in plant traits can affect attraction distance, movement patterns of parasitoids, and ultimately spatial patterns of plantâinsect interactions. It is therefore important to consider plantâtrait variation in HIPVs when studying animal foraging behaviour and multiâtrophic interactions in a spatial context.
