Résumé Trois extraits ont été obtenus de chacune de quatre plantes-hôtes: sucres/glycosides; acides aminées/bases organiques; acides organiques. Les quatre plantes-hôtes étudiées furent le sapin baumier, et les épinettes blanc, noir, et rouge. Le comportement gustatoire des larves a été étudié en raison de l'effet de combinaisons d'extraits de chaque plantehôte. Les résultats comparent la préférence des larves ainsi que leur consommation totale envers ces extraits.
Notes:
Abstract Three extracts were obtained from each of four host plants: sugars/glycosides; amino acids/bases; and organic acids. The four hosts studied were balsam fir, black spruce, red spruce, and white spuce. The effects of recombined host plant extracts on the feeding behaviour of eastern spruce budworm larvae were examined in two-choice tests. Results compare feeding preferences as well as feeding rates between combinations of extracts. The importance of each class of polar compounds is discussed.
