The omnivorous predator Macrolophus pygmaeus induces production of plant volatiles that attract a specialist predator

It has become clear that omnivorous predators can induce plant defences affect the performance and host choice of herbivores. They are also known to production volatiles behaviour herbivores searching for plants. These may other predators, which was investigated here. The predatory mite Phytoseiulus persimilis preferred plants previously exposed mirid Macrolophus pygmaeus over clean mites were equally attracted omnivore subsequently infested by spider (Tetranychus urticae, prey omnivore) with alone. Moreover, more than but not omnivore. significantly on omnivores still present. Experience from without resulted in a loss preference emitted Analysis showed exposure induced qualitative quantitative changes volatile blend. Together, these results suggest interfere predators. consequences such interference biological pest control remain be investigated.
