Abundance and community composition of arboreal spiders : the relative importance of habitat structure, prey availability and competition

Creator:: Halaj, Juraj
Abstract:: This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed...

Revision of the genus Platylygus (Heteroptera: Miridae)

Creator:: Equihua-Martinez, Armando
Abstract:: The genus Platylygus Van Duzee was erected in 1915 and revised by Kelton and Knight in 1970 describing 26 new species from United State and Mexico. Despite this prior revision, taxonomic problems have been encountered with the use of the keys and in the identification given the close similarity among...

A revision of the Nearctic species of Sympherobius Banks (Neuroptera: Hemerobiidae)

Creator:: Oswald, John D. (John David)
Abstract:: The Nearctic species of the genus Sympherobius Banks are revised. Seventeen species are recorded from the region. Two new species, S. constrictus and S. quadricuspis are described from California and Arizona respectively. Four new specific synonyms are proposed (junior synonym(s) first): S. brunneus Nakahara and S. stangei Nakahara = S....

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...

Biological studies on Saldula palustris (Douglas) with emphasis on factors influencing wing pigmentation (Heteroptera:Saldidae)

Creator:: Stock, Mary Wilford
Abstract:: The life history and wing pattern variation of the intertidal shore bug, Saldula palustris (Douglas), were studied in field and experimental populations from June 1970 until February 1972. The study site was an estuarine salt marsh on Yaquina Bay near Toledo, Oregon. The insects live below mean high water level...

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...

Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

Creator:: Asquith, Adam
Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...
