An Indirect Defence Trait Mediated through Egg-Induced Maize Volatiles from Neighbouring Plants
Attack of plants by herbivorous arthropods may result in considerable changes to the plant's chemical phenotype with respect to emission of herbivore-induced plant volatiles (HIPVs). These HIPVs have been shown to act as repellents to the attacking insects as well as attractants for the insects antagonistic to these herbivores. Plants can also respond to HIPV signals from other plants that warn...
متن کاملHerbivore-induced plant volatiles induce an indirect defence in neighbouring plants
1 Many plant species respond to herbivory with increased emission of volatile organic compounds (VOCs): these attract carnivorous arthropods and thereby function as an indirect defence mechanism. Whether neighbouring plants can ‘eavesdrop’ on such airborne cues and tailor their defences accordingly, remains controversial. 2 We used Lima bean plants ( Phaseolus lunatus ) to investigate whether h...
متن کاملMaize landraces recruit egg and larval parasitoids in response to egg deposition by a herbivore.
Natural enemies respond to herbivore-induced plant volatiles (HIPVs), but an often overlooked aspect is that there may be genotypic variation in these 'indirect' plant defence traits within plant species. We found that egg deposition by stemborer moths (Chilo partellus) on maize landrace varieties caused emission of HIPVs that attract parasitic wasps. Notably, however, the oviposition-induced r...
متن کاملMemory of plant communications for priming anti-herbivore responses
The emission of a specific blend of volatiles in response to Mythimna separata (herbivore-induced plant volatiles, HIPVs) plays a great ecological role by priming neighbouring plants. Maize plants placed downwind of infested, conspecific plants showed reduced larval development not only immediately after exposure to HIPVs but also when receiver plants were tested after a time lag of up to 5 day...
متن کاملCosts of induced volatile production in maize
Herbivore-induced plant volatiles have been shown to serve as indirect defence signals that attract natural enemies of herbivores. Parasitoids and predators exploit these plant-provided cues to locate their victims and several herbivores are repelled by the volatiles. Recently, benefits, in terms of plant fitness, from the action of the parasitoids were shown for a few systems. However, the cos...
