The use of Herbivore Induced Plant Volatiles by Parasitoid Wasps

Rieta Gols du Laboratory of Entomology, Wageningen University (the Netherlands) en visite au sein du Pole de Protection des Plantes, présentera ses travaux de recherche le jeudi 22 mars à 11 heures en salle 1 du 3 P au Cirad Ligne Paradis à Saint Pierre.

Résumé

Parasitoids wasps attacking herbivorous host use herbivoreinducedplant volatiles (HIPVs) to locate plants infested withtheir hosts. Despite the numerous studies investigating whatcomponents in the HIPV blend determine their attractivenessto parasitoids, this issue has not or only poorly beenresolved. In this presentation I will present case studiesinvestigating HIPV mediated foraging behavior in parasitoidsattacking caterpillars that feed on brassicaceous plantspecies. I will discuss the results considering the ecology andbiology of the parasitoids
