Recent science knows a lot about individual trophic levels: primary producents, consumers, and carnivores. However, the interactions between these trophic levels are much less explored. It is becoming apparent that tri-trophic interaction between plants, herbivorous insect, and insectivorous birds are more complicated and finely tuned than expected. It has been suggested that insectivorous birds may be guided by herbivore induced plant volatiles to plants with high abundances of insect. The production of herbivore-induced compounds in plants is partly mediated by jasmonic acid signaling pathway. Methyl jasmonate (MeJA) was proved to be the suitable agent for induction of volatiles compounds similar to those induced by the chewing herbivorous insect in many plant species. We studied the effect of MeJA on volatile emissions and attractivitty for insectivorous birds in mature grey willows (Salix cinerea) in natural conditions. We found out that MeJA-treated trees released greater quantities of certain volatiles and attracted more birds than non-treated trees.
