Defensive Traits during White Spruce (Picea glauca) Leaf Ontogeny
Insects, 2021 Changes during leaf ontogeny affect palatability to herbivores, such that many insects, including the eastern spruce budworm (Choristoneura fumiferana (Clem.)), are specialist feeders on growing conifer leaves and buds.
