The ecology of insects associated with waste water lagoons

Creator:: Sturgess, Brian Thomas
Abstract:: The purpose of this study was to determine what insect species occurred in waste water facilities at Corvallis, Oregon, and to correlate these species with the chemical, physical, and biological features common to these facilities. Data collected on a routine basis included dissolved oxygen, temperature, algal density, and insect population...

The species composition and adaptations of insects in an intermittent stream in western Oregon

Creator:: Tew, Michael Peter
Abstract:: The insect fauna of a small second order intermittent stream near Corvallis, Benton County, Oregon was studied. The species composition was determined, attempts were made to monitor migration to the stream, qualitative and quantitative benthos samples were taken, emergence was sampled, the dry stream bed was examined for forms of...

A study of ticks (Acarina: Ixodidae) and chiggers (Trombiculidae) from two areas in western Oregon

Creator:: Easton, Emmett Richard
Abstract:: A study of the host range and distribution of ticks and chiggers (Acari) was undertaken in two contrasting forested areas of western Oregon. Acarines were sampled from host mammals which were trapped along line transects laid out in both areas, each consisting of 18 stations 50 feet apart. Hosts were...

The role of acoustical signals in the communicative behavior of the water scavenger beetles, Tropisternus (Coleoptera:hydrophilidae)

Creator:: Ryker, Lee Chester
Abstract:: The communicative behavior of five species and subspecies of Tropisternus Solier (Coleoptera: Hydrophilidae) was studied. These aquatic beetles have stress and calling chirps (both sexes), a second male calling signal (one species), a single male courtship sound (usually), a male copulatory sound, and a female aggressive rejection buzz (three species)....

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...

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...

The morphology and biology of Macrovelia hornii Uhler (Heteroptera : Mesoveliidae)

Creator:: Anderson, Aage Bernard
Abstract:: The external and internal morphology are considered and important morphological characters are found which relate Macrovelis to the family Mesoveliidae. Both macropterous and Brachypterous forms occur throughout the western half of the United States. The adults and nymphs are restricted to the margins of springs and streams during the reproductive...
