Survival and development of the flat-headed fir borer in forest residues as affected by host and microclimatic conditions

Creator:: Scott, Donald Wayne
Abstract:: The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...

Evaluating the Attractiveness of Pacific Northwest Native Plants to Insects and Gardeners

Creator:: Anderson, Aaron G.
Abstract:: Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...

Gamma irradiation of the western cherry fruit fly for the sterile male control technique

Creator:: Brown, Robert David
Abstract:: The western cherry fruit fly, Rhagoletis indifferens Curran, was studied to determine the suitability of the sterile insect technique for its control. To obtain insect material, field collection of maggots is preferred to sifting of soil or rearing on artificial diet. The western cherry fruit fly is strictly univoltine; only...

Habitat management for beneficial insects on Willamette Valley vegetable and berry farms

Creator:: Russell, Michael C.
Abstract:: Conservation biological control involves manipulating farm landscapes or management systems to enhance populations of beneficial predators of agricultural pests. Farmscaping is one aspect of conservation biological control where predators of important pests are identified, the availability on the farm landscape of resources and habitat components needed by the beneficials to...

The street tree problem for the Pacific Northwest

Creator:: Neill, John Wesley
Abstract:: A regional analysis of the street tree problem has been undertaken in order to evolve a system of tree classification which would be useful to city planners, arborists, and landscape architects who have the responsibility of selecting trees to fulfill their design requirements for the city street. Three lines of...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Potential carbon storage at the landscape scale in the Pacific Northwest, U.S.A.

Creator:: Smithwick, Erica Ann Hoffa
Abstract:: Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...
