Although plants as sessile beings look passive to the human eye, they are nowadays
recognized to interact and communicate with their environment in complex ways. They
use these abilities to face the multitude of biotic and abiotic threats they are
constantly exposed to. Among these dangers insect herbivores may be one of the most
severe.

Since herbivorous insects normally choose plants suitable for the nutrition of their
offspring as sites for oviposition, insect eggs are the first stage of an actual
attack of a plant by larvae. As such they are the first stage to induce defense
responses of the plant. Defense induced by eggs has therefore been termed early
herbivore alert''.

This PhD thesis focuses on the chemoecological analyses of interactions between
pine, pine sawflies and parasitoids specialized on sawfly eggs laid on pine. The
thesis is based on knowledge about the induction of defensive responses in Pinus
sylvestris by egg deposition of the pine sawfly Diprion pini. Egg-induced pine
releases odor attracting the egg parasitoid Closterocerus ruforum. The egg-induced
pine odor is known to be characterized by enhanced quantities of the sesquiterpene
(E)- beta-farnesene.
