Plants damaged by herbivores emit quantitatively and/or qualitatively different volatiles from those emitted from intact plants. Such volatiles are known to induce defense-related genes in neighboring plants that are exposed to the volatiles, and consequently enhance their resistance against herbivores in intact plants. This is called a plant-plant communication. Here, we investigated whether a composition of arthropods community on plants is affected by such a plant-plant communication. To test this, in the middle of a willow plantation in Shiga, Japan, we placed (1) intact willow plants, Salix eriocarpa, exposed to volatiles from conspecific plants infested by leaf beetles, (2) willow plants infested by leaf beetles, and (3) intact willow plants (control). We then counted the number of arthropods immigrated into plants with different treatments, and the number of leaves infested by herbivores (every day for one week, and then once in a month for three month). The timing of immigration of leaf beetles, and the composition of arthropods were apparently different among three treatments. Interestingly, the number of newly emerged sprouts was higher in intact plants exposed to infested plant volatiles than in intact control plants. Such changes would affect arthropods’ niches in a local plant community.
