Herbivore-induced plant volatiles as cues for habitat assessment by a foraging parasitoid.
1. Animals usually require information about the current state of their habitat to optimize their behaviour. For this, they can use a learning process through which their estimate is continually updated according to the cues they perceive. Identifying these cues is a long-standing but still inveterate challenge for ecologists. 2. The use of plant cues by aphid parasitoids for the assessment of ...
متن کاملPlant Volatiles Yielding New Ways to Exploit Plant Defence
When plants are damaged, they produce semiochemicals which can act as repellents for herbivorous pests and as attractants for organisms antagonistic to these pests, e.g., predators and parasitic wasps. Plants can also produce signals that warn other plants of impending attack. From this range of phenomena, it is possible to identify new ways to control pests. Although, in the past, we have need...
متن کاملPlant volatiles
Plant volatiles are the metabolites that plants release into the air. The quantities released are not trivial. Almost one-fifth of the atmospheric CO2 fixed by land plants is released back into the air each day as volatiles. Plants are champion synthetic chemists; they take advantage of their anabolic prowess to produce volatiles, which they use to protect themselves against biotic and abiotic ...
متن کاملUpdate on Biochemistry of Plant Volatiles Biochemistry of Plant Volatiles
Plants have a penchant for perfuming the atmosphere around them. Since antiquity it has been known that both floral and vegetative parts of many species emit substances with distinctive smells. The discovery of the gaseous hormone ethylene 70 years ago brought the realization that at least some of the compounds emitted may have physiological significance without any distinctive smell to humans....
متن کاملNew evidence for a multi-functional role of herbivore-induced plant volatiles in defense against herbivores.
A diverse, often species-specific, array of herbivore-induced plant volatiles (HIPVs) are commonly emitted from plants after herbivore attack. Although research in the last 3 decades indicates a multi-functional role of these HIPVs, the evolutionary rationale underpinning HIPV emissions remains an open question. Many studies have documented that HIPVs can attract natural enemies, and some studi...
