Abstract
This work is an update of a recently published review and is consistently referred to this article and recent findings about plants’ indirect defense are added on. Herbivore induced plant volatiles (HIPVs) and their effects on the third trophic level that involves predators and parasitoids are discussed. The fact that plants are not passive individuals is confirmed on the basis of several studies. Plants can perceive and respond to cues in their environments with plastic morphological, physiological and behavioral traits. Plasticity allows plants to tailor their defenses to their current and expected risks caused by herbivores. The “cry for help” of plants is also observed from the carnivores’ point of view. The volatile mixture contains crucial information for decisions of carnivorous insects. Furthermore, the most important methods to examine the behavioral response of carnivorous insects to HIPVs are presented not only in laboratory set ups but also in the field. Manipulations of plants by silencing genes or over-expressing genes can help to understand mechanisms of indirect defense. Various interesting examples of indirect defense reveal the possibility to use HIPVs in biological control. Therefore, the application of synthetic pesticides, that pollute the environment, may be reduced in the future.
