The Occurrence of Insect Parasites of Choristoneura fumiferana (Clem.), in Oregon

Journal of Economic Entomology, 1959
To date, 34 species of primary parasites have been recovered from the spruce bud worm ( Choristoneura fumiferana (Clem.)) in Oregon. Of these, 15 species are considered of major importance. Analysis of the abundance and distribution of these parasites was based on concepts and methods used in plant sociology.

PATHOGENICITY OF CHORISTONEURA FUMIFERANA NUCLEOPOLYHEDROVIRUS PROPAGATED IN VITRO AT DIFFERENT INCUBATION TEMPERATURES

In Vitro Cellular & Developmental Biology - Animal, 2003
To optimize the in vitro production of Choristoneura fumiferana nucleopolyhedrovirus (CfMNPV) as a potential microbial pest control agent, the pathogenicity of occlusion bodies (OBs) produced in two cell lines at three incubation temperatures was determined by bioassay. A plaque-purified isolate of CfMNPV was amplified in permissive C.

Solution Structure of an Antifreeze Protein CfAFP-501 from Choristoneura fumiferana

Journal of Biomolecular NMR, 2005
Antifreeze proteins (AFPs) are widely employed by various organisms as part of their overwintering survival strategy. AFPs have the unique ability to suppress the freezing point of aqueous solution and inhibit ice recrystallization through binding to the ice seed crystals and restricting their growth.

Studies on two ecdysone receptor isoforms of the spruce budworm, Choristoneura fumiferana

Molecular and Cellular Endocrinology, 1999
A full-length cDNA clone corresponding to the Choristoneura fumiferana ecdysone receptor-A isoform (CfEcR-A) was isolated. The deduced amino acid sequence of CfEcR-A differed from CfEcR-B in the NH2-terminal region of the A/B domain. The CfEcR-A-specific region showed high amino acid identity with EcR-A isoforms of Manduca sexta, Bombyx mori ...

Expression of a Tranosema rostrale polydnavirus gene in the spruce budworm, Choristoneura fumiferana

Microbiology, 2000
The endoparasitic wasp Tranosema rostrale (Ichneumonidae) transmits a polydnavirus (PDV) to its host, Choristoneura fumiferana, during oviposition. Unlike most other PDVs examined, the virus of T. rostrale (TrPDV) does not appear to play an important role in suppressing the host cellular immune response. However, it inhibits host metamorphosis.

Cloning and expression of a putative transferrin cDNA of the spruce budworm, Choristoneura fumiferana

Insect Biochemistry and Molecular Biology, 2004
A spruce budworm (Choristoneura fumiferana) transferrin cDNA (CfTf) was isolated and cloned from a cDNA library that was constructed using mRNA from fifth to sixth instar larvae. CfTf cDNA encoded a predicted protein of 681 amino acids with a molecular mass of approximately 76 kDa.

A molt-associated chitinase cDNA from the spruce budworm, Choristoneura fumiferana

Insect Biochemistry and Molecular Biology, 2002
Chitinase (CfChitinase) cDNA from the spruce budworm, Choristoneura fumiferana, was cloned using reverse transcription PCR and cDNA library screening. The CfChitinase cDNA was determined to be 2856 nucleotides long with the longest open reading frame made up of 1671 nucleotides that encoded a protein that was 557 amino acid long with a predicted ...

Purification and properties of a nuclear polyhedrosis virus from Choristoneura fumiferana

Canadian Journal of Microbiology, 1975
The polyhedral inclusion bodies of a nuclear polyhedrosis virus from the spruce budworm Choristoneura fumiferana were purified by fluorocarbon treatment, sucrose columns, sucrose density gradients, and equilibrium centrifugation. The preparation yields a single and homogeneous band in potassium tartrate gradients at a density of 1.193 g/ml.

Temporal, spatial and induced expression of chitinase in the spruce budworm, Choristoneura fumiferana

Journal of Insect Physiology, 2003
Temporal, spatial and induced expression of Choristoneura fumiferana chitinase (CfChitinase) was studied using immunohistochemistry and Western blots. CfChitinase was detected in the integument, the midgut peritrophic membrane, the cuticular lining of the trachea, the spiracle, and salivary glands.
