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 ...

Winter-active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta-solenoid fold. [PDF]
FEBS JAntifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

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.

Entomologia Experimentalis et Applicata, EarlyView.Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.
