THE EFFECT OF A MICROSPORIDIAN PARASITE ON THE DEVELOPMENT, REPRODUCTION, AND MORTALITY OF THE SPRUCE BUDWORM, CHORISTONEURA FUMIFERANA (CLEM.)

, 1958
Infection of the spruce budworm, Choristoneura fumiferana (Clem.), by the microsporidian parasite Perezia fumiferanae Thorn, retards both larval and pupal development and reduces pupal weight, fecundity, and adult longevity.

Expression of the fusolin gene of Choristoneura fumiferana entomopoxvirus in the baculovirus insect cell system

, 2001
The fusolin (fus) gene of Choristoneura fumiferana entomopoxvirus was cloned and expressed in insect cells via the baculovirus expression vector system using the polh promoter.

Temporal variation in spatial genetic structure during population outbreaks: Distinguishing among different potential drivers of spatial synchrony

Evolutionary Applications, 2019
Spatial synchrony is a common characteristic of spatio‐temporal population dynamics across many taxa. While it is known that both dispersal and spatially autocorrelated environmental variation (i.e., the Moran effect) can synchronize populations, the ...

Spermatozoïdes apyrènes et eupyrènes et réceptivité postcopulatoire chez les femelles Choristoneura rosaceana et C. Fumiferana

, 2018
Lors de l’accouplement, les mâles lépidoptères transfèrent deux types de spermatozoïdes, les eupyrènes et les apyrènes. Dans les heures qui suivent, les femelles des papillons de nuit cessent généralement de produire la phéromone sexuelle.

Early growth decline and vegetation change predict black spruce mortality following spruce budworm outbreaks

Ecological Indicators
Tree mortality is accelerating across boreal forests due to increasing biotic disturbances, but the mechanisms linking defoliation, individual tree stress, and canopy decline remain poorly understood.

Site-infidelity by budworm-linked warblers at the edge of an area defoliated by spruce budworm

Avian Conservation and Ecology, 2021
Most songbird species show some degree of fidelity to their previous breeding location, especially after successful reproduction. However, species associated with highly dynamic food sources (e.g., outbreaking insects) may have to adopt more flexible ...

Effects of selected juvenile hormone analogs on sixth-instar larvae of the eastern spruce budworm, Choristoneura fumiferana Clemens (Lepidoptera: Tortricidae)

The effect of 7 juvenile hormone analogues on the development of larvae of Choristoneura fumiferana was studied in the laboratory at 23 degrees C, LD 16:8 and 65% RH by topical application of the compounds to early 6th-instar larvae.

A mechanistic perspective of possible influences of climate change on defoliating insects in North America's boreal forests

Silva Fennica, 1996
There is no doubt that tree survival, growth, and reproduction in North America's boreal forests would be directly influenced by the projected changes in climate if they occur.

THE MATING STATUS OF SPRUCE BUDWORM MALES, CHORISTONEURA FUMIFERANA (CLEM.) (LEPIDOPTERA: TORTRICIDAE), CAUGHT IN PHEROMONE-BAITED TRAPS

, 1986
The mating status of recently-mated male spruce budworm moths, Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae), caught in traps baited with five different treatments was indexed.
