Evolution of signal emission by non-infested plants growing near infested plants to avoid future risk.
Several plant species indirectly defend themselves against herbivory by attracting natural enemies of herbivores by releasing signal chemicals when infested. Previous empirical research suggested that the chemical signals also reflexively induce signal emission by neighboring undamaged plants. We hypothesize that such a reflexively induced signal is a defensive strategy used by undamaged plants...
متن کاملPlants Attract Parasitic Wasps to Defend Themselves against Insect Pests by Releasing Hexenol
BACKGROUND Plant volatiles play an important role in defending plants against insect attacks by attracting their natural enemies. For example, green leaf volatiles (GLVs) and terpenoids emitted from herbivore-damaged plants were found to be important in the host location of parasitic wasps. However, evidence of the functional roles and mechanisms of these semio-chemicals from a system of multip...
متن کاملIsoprene interferes with the attraction of bodyguards by herbaceous plants.
Isoprene is the most abundant volatile compound emitted by vegetation. It influences air chemistry and is part of plant defense against abiotic stresses. However, whether isoprene influences biotic interactions between plants and other organisms has not been investigated to date. Here we show a new effect of isoprene, namely its influence on interactions between plants and insects. Herbivory in...
متن کاملVibratory stimuli in host location by parasitic wasps.
Parasitic wasps use a broad spectrum of different stimuli for host location and host acceptance. Here we review the published evidence for the use of mechanical stimuli, i.e. substrate born vibrations which are invariably regarded as vibrotaxis. We propose a set of criteria to class behavioural reactions as vibrotaxis or vibrokinesis and characterize 14 studies reporting the use of host-associa...
