Abstract:

 

Herbivores can cause many types of damage to plants. Caterpillars ingest small sections of the leaves, while others feed on specific parts of the leaf material. In this point, essential oils from coniferous trees contain secondary metabolites that act as feeding deterrent for a great number of herbivore insect species. Attacks by herbivores elicit changes in the bouquet of volatiles released by plants. Terpenoid chemicals exist both as constitutive and massively induced defenses in conifers. Hereby we studied the factors contributing to the specificity of induced defensive responses in economically important pine species of Turkey, Pinus brutia Ten., against most famous pest, pine processionary moth (Thaumetopoea wilkinsoni Tams). We quantified volatile organic compounds (VOCs) emissions of needle and some other needle contents. Needle feeding by the caterpillar increased emissions of VOCs. We discuss the possible mechanisms responsible for reducing the tree's signalling capacity triggered by Th. wilkinsoni oviposition and how enhancement/suppression of VOCs can influence the interaction between the tree, the pest and other biotic/abiotic factors in environment.
