Regulation of pheromone inhibition in mated females of Choristoneura fumiferana and C. rosaceana
Journal of Insect Physiology, 2000In the spruce budworm, Choristoneura fumiferana, and the obliquebanded leafroller, C. rosaceana, mating significantly depressed pheromone production after 24 h. On subsequent days, the pheromone titre increased slightly in C. fumiferana, but not in C. rosaceana. No pheromonostatic activity was associated with male accessory sex gland (ASG) extracts, 20-

Effect of RH-5992 on adult development in the spruce budworm, Choristoneura fumiferana
Insect Biochemistry and Molecular Biology, 2002The effect of RH-5992 (tebufenozide), a non-steroidal ecdysone agonist, on adult development of the spruce budworm, Choristoneura fumiferana, was investigated by administering the compound intrahemocoelically to pupae on days 1-6 after pupal ecdysis.

Abstract Electrophysiological investigations show that chemosensitive cells in tarsal setae of the spruce budworm are sensitive to at least two salts and possibly water. Two cells are involved in the salt response and one in the possible water response. Each seta also has a cell which responds to mechanical deformation.

Female eastern spruce budworm, Choristoneura fumiferana (Clemens), inoculated sublethally as fourth or fifth instars with Nosema fumiferanae (Thomson), exhibited significant reductions in size, fecundity, and total egg complement. Mating success and egg fertility were similar for treated and control insects.

Virus particles and polyhedra develop in patches of viroplasm in the cytoplasm of mid-gut cells of larvae of the spruce bud worm, Choristoneura fumiferana (Clemens). Normal components of the cell disintegrate as the disease spreads, and either they completely disappear or mitochondria, ribosomes, and other components form rings in the outer regions of

The Choristoneura fumiferana entomopoxvirus (CfEPV) spheroidin gene was identified and localized on three XbaI restriction fragments (total size 4.73 kb). The fragments were cloned and sequenced. The spheroidin gene had an open reading frame of 2997 nucleotides encoding a putative protein with a predicted size of 115 kDa.

Comparative activity of Choristoneura fumiferana nucleopolyhedrovirus propagated in different hosts
Pest Management Science, 2004Abstract The biological activity of the Ireland strain of Choristoneura fumiferana (Clem) nucleopolyhedrovirus ( Cf MNPV) propagated in different hosts was determined to provide the basis upon which genetically modified

A bioassay technique for Entomophthora sphaerosperma on the spruce budworm, Choristoneura fumiferana
Journal of Invertebrate Pathology, 1979Abstract A technique for conducting bioassays of Entomophthora sphaerosperma on sixth-instar larvae of the spruce budworm, Choristoneura fumiferana , was developed. Four assays were conducted by showering conidia on 10 larvae for each of 10 to 20 doses per assay.

Phylogenomics of the Choristoneura fumiferana species complex (Lepidoptera: Tortricidae)
2013The phylogenetic relationships of the destructive spruce budworm group of forest pests (Choristoneura fumiferana species complex) have previously been explored using allozymes, microsatellites, mitochondrial genes and a nuclear gene, but remain poorly resolved with conflicting topologies.

The growth properties of cell lines derived from Spodoptera frugiperda (alfalfa looper) and Choristoneura fumiferana (spruce budworm) were investigated. The data demonstrated that the spruce bud worm cell line grew more slowly than the alfalfa looper cell line, and this reduced growth rate appeared to affect the rate of baculovirus replication in ...
