Diurnal and seasonal flight patterns of bark beetles (Coleoptera : Scolytidae) associated with Douglas-fir forests of western Oregon

Creator:: Daterman, Gary E.
Abstract:: The study was undertaken to determine the seasonal and diurnal flight patterns of scolytid beetles inhabiting a second growth forest of Douglas-fir (Pseudotsuga menziesii (Mirb.)Franco) in western Oregon. Air temperatures, relative humidity, light intensity, and wind velocities were recorded for evaluation of their influence on flight activity. The insects were...

Biology studies of Macrosiphum avenae (Fabr.), Acyrthosiphon dirhodum (Walker), and Rhopalosiphum padi (L.) on Gramineae in western Oregon

Creator:: Greene, Gerald L.
Abstract:: Field biology studies of three grain aphids, Macrosiphum avenae (Fabr.), Acyrthosiphon dirhodum (Walker), and Rhopalosiphum padi (L.) were conducted near Corvallis, Oregon, from 1961 to 1964. Populations of M. avenae were found on grain plants, and alatae entering spring barley may have been from wheat fields. Specimens were found more...

Circadian rhythms in Megachile rotundata (Fabricius) and Nomia melanderi Cockerell

Creator:: Tweedy, David Graham
Abstract:: The purpose of the study was to determine an emergence rhythm, its period, and the developmental stages susceptible to emergence synchronization in the leafcutter bee Megachile rotundata (Fabricius). An attempt was made to determine if an oxygen consumption rhythm was present in the pupal and adult stages of the alkali...

A comparative study of the isozymic proteins and the effect of metachemogenesis in the tissues of Periplaneta americana (L.)

Creator:: Beckendorf, Gerald Walter
Abstract:: An attempt was made to demonstrate isozymic forms of esterase, MDH, LDH and GPDH and the variation in enzyme pattern with increasing age in the thoracic muscle, appendage muscle and hemolymph of the American cockroach, Periplaneta americana. Sampled specimens of both sexes were aged one through seven days, two weeks...

The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera: Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...

Mechanisms of orientation in the leaf-cutter bee Megachile rotundata (Fabricius)

Creator:: Osgood, Charles Edgar
Abstract:: The leaf- cutter bee Megachile rotundata (Fabricius) is an important alfalfa pollinator in western North America. This study was designed to provide information on methods of orientation used by M. rotundata in order to make recommendations regarding the parameters within which adult nesting populations may be relocated. Preliminary studies suggest...

Population development of Scutigerella immaculata (Newport), in laboratory and greenhouse cultures

Creator:: Ramsey, Henry Lee
Abstract:: Population development of the symphylan, Scutigerella immaculata (Newport), was studied in laboratory cultures. Also symphylan injury to greenhouse plants was investigated. Plastic polyethylene containers partly filled with damp ground hemlock bark were used to culture symphylan in the laboratory. Fresh lettuce food was supplied to the cultures weekly. Factors which...

Naphthalene resistance in a house fly strain : its inheritance and characteristics

Creator:: Schafer, James Arnold
Abstract:: A combination of genetical and biochemical methods were utilized in investigating house fly resistance to naphthalene. The inheritance of resistance was determined by crossing a naphthalene resistant strain of Musca domestica L. with a susceptible mutant marker strain. Biochemical comparisons were made on substrains isolated from the progeny of these...

Induction of microsomal oxidases by dieldrin in house flies

Creator:: Walker, Charles Robert
Abstract:: Previous investigations have shown that exposure to DDT results in increased activity in soluble and microsomal enzyme in insects. These responses in DDT-resistant Triatoma infestans nymphs and in adults of DDT-resistant Musca domestica (the common house fly) are accompanied by increased RNA and protein synthesis. The phenomenon has been termed...

Essential fatty acids in noctuid moths : their nutrition and metabolism

Creator:: Grau, Philip Alvin, 1941-
Abstract:: The polyunsaturated fatty acids (PUFA) are known to be required for larval growth and normal wing development in several species of Lepidoptera but most of the basic information necessary for a complete understanding of this nutritional phenomenon has not been gathered. This includes the role of each of the essential...
