The taxonomic value of the metathoracic wing in the Scutelleridae (Hemiptera: Heteroptera)

Creator:: Au, Eunice Chizuru
Abstract:: Classification based on metathoracic wing venation does not coincide with the existing higher classification of the family Scutelleridae. The wings of the genera in the Scutellerinae possess a similar general pattern of venation which is quite distinct from that of Eurygasterinae, Odontoscelinae, Odontotarsinae, and Pachycorinae. The Scutellerinae wings possess three...

Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

Cereal stem moth, Ochsenheimeria vacculella Fischer von Röslerstamm (Lepidoptera : Ochsenheimeriidae) : field biology and larval development on selected grasses and cereals in Western Oregon

Creator:: Panasahatham, Sarote
Abstract:: The seasonal life history of the cereal stem moth (CSM), Ochsenheimeria vacculella Fischer von Roslerstamm, (Lepidoptera : Ochsenheimeriidae) was investigated in a commercial field of annual ryegrass in the Willamette Valley, OR from January 1993 to August 1994. Phenology of life stages, effect of temperature on eclosion, and development of...

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,...

The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...

The effect of sublethal doses of dieldrin, parathion, and sevin on the calling song of Acheta domesticus L. (Orthoptera: Gryllidae)

Creator:: Young, Conny Lee
Abstract:: The objectives of this study were: a) to obtain and evaluate equipment for bio-acoustical analysis for this work and for future work in the analysis of insect sounds, b) to study the acoustical and sexual behavior of Acheta domesticus L., and c) to determine methods for analyzing the changes effected...

A revision of the genus Notiphila Fallén (Diptera:Ephydridae) from America north of Mexico

Creator:: Mathis, Wayne N.
Abstract:: The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...

Transmission efficiency and life table parameters of western flower thrips, Frankliniella occidentalis (Pergande) exposed to tomato spotted wilt virus-impatiens serotype

Creator:: Sether, Diane M.
Abstract:: Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or...

A revision of the genus Deraeocoris Kirschbaum (Heteroptera:Miridae) from western America north of Mexico

Creator:: Razafimahatratra, Vincent de Paul
Abstract:: The genus Deraeocoris Kirschbaum of western America north of Mexico was revised. Approximately 10,000 specimens from the Nearctic Region were examined. Taxonomic characters used by previous authors were reevaluated. In addition to the male parameres, the male vesica and the female posterior wall of the bursa copulatrix and sclerotized rings...
