Biological interrelationships between the Ambrosia beetle Xyleborus dispar with its symbiotic fungus Ambrosiella hartigii

Creator:: French, John Richard Joseph
Abstract:: Biological interrelationships between the ambrosia beetle Xyleborus dispar (F.) (Coleoptera:Scolytidae) with its symbiotic fungus, Ambrosiella hartigii Batra (Fungi Imperfecti) were investigated in western Oregon. Postdiapause adults of X. dispar collected in March through June with rotary nets, and excised from overwintered and newly attacked host material, produced a single generation...

Population dynamics of the cinnabar moth, Tyria jacobaeae (Lepidoptera: Arctiidae)

Creator:: Isaacson, Dennis
Abstract:: The dynamics of a field population of the cinnabar moth, Tyria jacobaeae L., were studied near Jordan, Linn County, Oregon. In both 1970 and 1971 larval populations were so large that all foliage of the host weed, tansy ragwort, Senecio jacobaea L., was consumed. The ensuing starvation accounted for the...

Creator:: Nebeker, T. Evan
Abstract:: A population of the Douglas-fir cone moth, Barbara colfaxiana (Kft. ), was studied on the Buckhead Seed Production Area, Oakridge, Oregon, during 1971 and 1972. A method of estimating cone and insect populations is presented. Factors contributing to the mortality of B. colfaxiana are discussed, with resinosis being the critical...

Toward a continuous culture of bumble bees (Bombus Latr.)

Creator:: Seibert, Thomas Floyd
Abstract:: Out of 53 queens captured for initiating colonies in the laboratory, 33 laid eggs (62 percent), 29 of these produced colonies (55 percent), and 14 produced queens (26 percent). A behavioral model depicts the activities of queens from spring emergence through colony development. A discussion of its application to bumble...
