Publikováno v: The Coleopterists Bulletin. 65:182-184
There are about 500 species of bark beetles (Coleoptera: Curculionidae: Scolytinae) in the United States (Wood 1982). A number of them are important disturbance agents in forested ecosystems, occasionally creating large tracts of dead trees. One erup

Publikováno v: The Bark Beetles, Fuels, and Fire Bibliography
Data collected from Douglas-fir (Pseudotsuga menziesii) stands infested by the Douglas-fir beetle (Dendroctonus pseudotsugae) in Wyoming, Montana, Idaho, and Utah, were used to develop models to estimate amount of mortality in terms of basal area kil

Attack Behavior and Host Utilization of Coccygomimus disparis (Hymenoptera: Ichneumonidae) in the Laboratory
Autor: H. M. Kulman, Willis C. Schaupp
Publikováno v: Environmental Entomology. 21:401-408
Coccygomimus disparis (Viereck) attacked most of the 16 novel hosts species offered in laboratory trials and produced viable adults in 7 of these species. The manner of host presentation significantly affected host recognition and acceptance; immobil

Autor: William E. Waters, Willis C. Schaupp, W. Jan A. Volney
Publikováno v: The Canadian Entomologist. 123:1095-1102
Parasitoid species attacking sparse, endemic populations of Choristoneura occidentalis Freeman and C. retiniana (Walsingham) are reported from 2 years of host collections at seven sites across southern Oregon. Results are compared with rearings from

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 9:1271-1278
From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38–84 years (average 64.4 years). The average age of the males was eight years less than th
