Biology of the yellowjacket parasitoid Bareogonalos canadensis (Harrington) (Hymenoptera: Trigonalyidae)

Creator:: Carmean, David
Abstract:: The known biology of Bareogonalos canadensis (Harrington) is based on literature records of six collections from three areas in the Pacific Northwest. The objective of this study was to obtain fundamental knowledge on the biology of B. canadensis, especially its distribution, abundance, and host species, as well as its potential...

Effects of stand density on site index in thinned stands of Douglas-fir in the Pacific Northwest

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: In site index studies, the hypothesis that height growth of most conifers is independent of stand density is commonly accepted. However, some studies have shown height growth to be influenced by density particularly on medium to poor sites. In this study two locations representing a high quality site (Hoskins area,...

Biology and host relations of Meteorus comunis (Cresson)

Creator:: West, Kenneth John
Abstract:: Fifteen species of Noctuidae (Lepidoptera) were collected in alfalfa and peppermint in western Oregon. Seven of these species were hosts for the braconid parasitoid Meteorus communis. The most frequently parasitized (percent) species were Agrotis ipsilon (35.3), Dargida procincta (15.0), and Peridroma saucia (6.9). Other species parasitized were Autographa californica (3.8)...

Systematics of the genus Rhizopogon inferred from nuclear ribosomal DNA large subunit and internal transcribed spacer sequences

Creator:: Grubisha, Lisa C.
Abstract:: Rhizopogon is a hypogeous fungal genus that forms ectomycorrhizae with genera of the Pinaceae. The greatest number and species of Rhizopogon are found in coniferous forests of the Pacific Northwestern United States, where members of the Pinaceae are also concentrated. Rhizopogon spp. are host-specific primarily with Pinus spp. and Pseudotsuga...
