Description Many plants release herbivore-induced plant volatiles (HIPVs) upon attack by a pest insect. These HIPVs can be used by natural enemies of the herbivores, both parasitoids and predators, as cues to locate their prey. The attraction of natural enemies is a promising strategy to help plants to combat insect attack. Use of natural enemies for biocontrol also fits well within our ambition to reduce use of pesticides. However, crop plants may have lost the ability to emit HIPVs, as these traits have been neglected in plant breeding. To be able to breed for an effective attraction of natural enemies, genetic variation for the emission of HIPVs has to be present in the plants species, that can be linked to attraction of parasitoids or predators of pests.
In this project, you will measure HIPVs in different Brassica accessions after infestation with insects. Next, several accessions will be used in olfactometer assays to link HIPVs with the behavior of natural enemies.
Used skills Insect bioassays, GC-MS, olfactometer assays
Requirements Breeding for resistance and quality (PBR-30306), ENT-50806 (Insect-Plant Interactions) or Biological Control of Insects (ENT-53806)
