Biology and feeding habits of pleocoma larvae (Coleoptera : Scarabaeidae) in western Oregon coniferous forest

Creator:: Fellin, David G.
Abstract:: Food habits and biology of five species of Pleocoma larvae were studied at a dozen forested sites in western Oregon between May 1960 and December 1961. First instar Pleocoma hatch in late summer and moult to second instars in early fall. Second and subsequent instars moult annually between mid-summer and...

Mechanisms of resistance in broccoli, Brassica oleracea italica to the garden symphylan, Scutigerella immaculata (Newport)

Creator:: Simagrai, Montri
Abstract:: Studies were conducted on the mechanisms contributing to resistance in broccoli, Brassica oleracea italica, to the garden symphylan, Scutigerella immaculata (Newport). Differences in resistance to symphylan injury were shown between five selected broccoli cultivars. The hybrid cultivars, Crusader, Green Duke and Bravo, showed a higher level of resistance to symphylans...

Sampling and management of garden symphylans (Scutigerella immaculata Newport) in western Oregon

Creator:: Umble, Jon R.
Abstract:: Garden symphylans (Scutigerella immaculata Newport) are increasingly important pests of below-ground parts of over 100 crops in Oregon. The focus of our work was to improve S. immaculata management through 1) development of a bait sampling method, 2) examination of the susceptibility of selected crops to S. immaculata feeding in...

An evaluation of factors influencing the management of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae)

Creator:: Kepler, Ryan M.
Abstract:: The black vine weevil (BVW), Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) is a persistent pest of nursery operations in the United States, feeding on over 140 species of plants. The goals of this research were to 1) assess the behavioral response of BVW to a commonly employed insecticide bifenthrin (Talstar 0.2G®)...

The biologies of predators (Coleoptera: Cleridae) of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins (Coleoptera : Scolytidae), in western Oregon

Creator:: Cowan, Bruce Dudley
Abstract:: Six species of Cleridae, including Enoclerus spegeus Fabricius, E. lecontei Wolcott, E. schaefferi (Barr), E. eximius Mannerheim, Thanasimus undatulus Say, and an undescribed species of Enoclerus, were found on Douglas-fir in western Oregon. E. sphegeus was the only clerid of the six species studied which was primarily associated with the...

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...

Structure, function, and analysis of Coleoptera and Heteroptera assemblages on two species of hazelnut in Oregon

Creator:: Wetherill, Karen R.
Abstract:: The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...
