Does the type of silvicultural practice influence spruce budworm defoliation of seedlings?
Ecosphere, 2021 Spruce budworm (Choristoneura fumiferana (Clem)) is the main defoliator in the boreal forest of North America, and its outbreaks have major ecological and economic consequences and represent a challenge for forest management.

Defoliation-induced changes in foliage quality may trigger broad-scale insect outbreaks
Communications Biology, 2022 Progression of a spruce budworm outbreak over seven years is associated with increased soil nutrient fluxes and availability and improved foliage quality in surviving host trees. This could create a bottom-up feedback that sustains an insect outbreak.

Structural dynamics at boreal forest edges created by a spruce budworm outbreak
Silva Fennica, 2015 Natural disturbances such as insect outbreaks create boundaries that influence vegetation patterns and ecological processes. To better understand the effects of natural edge creation on relatively intact forests and adjacent disturbed areas, we ...

In vivo function of Pgβglu-1 in the release of acetophenones in white spruce [PDF]
PeerJ, 2017 Eastern spruce budworm (Choristoneura fumiferiana Clemens) (ESBW) is a major forest pest which feeds on young shoots of white spruce (Picea glauca) and can cause landscape level economic and ecological losses.

Spruce budworm biological and nutritional performance responses to varying levels of monoterpenes
iForest - Biogeosciences and Forestry, 2013 Dose effect of six monoterpenes (α-pinene, bornyl acetate, camphene, δ-3-carene, terpinolene, tricyclene) found in the foliage of host trees was tested on sixth-instar spruce budworm (Choristoneura fumiferana (Clem.)) using artificial diet.

Suboptimal host tree benefits the overwintering of a destructive forest insect pest
Basic and Applied Ecology, 2023 Winter represents a stressful period for many organisms, and terrestrial insects are particularly susceptible to adverse thermal conditions. However, exposure to thermal stress and its effects on insect survival and performance can be modulated by ...
