摘要: When attacked by herbivores, plants release herbivore-induced plant volatiles (HIPV) that may function in direct defence repelling herbivores or reducing their growth. Emission of HIPV also contribute to indirect attracting natural enemies the herbivore. Here, cabbage (Brassica oleracea L.) (receiver plants) previously exposed and subsequently induced through feeding five Pieris brassicae L. caterpillars attracted more Cotesia glomerata parasitoids than control plants. HIPVs which receiver had been were emitted B. infested with 50 P. caterpillars. Control from undamaged In contrast, there no differences attraction wasps one ten larvae compared addition, RT-PCR demonstrated higher levels LIPOXYGENASE (BoLOX) transcripts HIPV-exposed Exposure emitter significantly inhibited growth rate both Mamestra rates on Our results demonstrate plant-plant signalling leading priming
