A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...

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...

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...

A revision of the North American species of Pactopus Leconte and Trixagus Kugelann (Coleoptera: Throscidae)

Creator:: Yensen, Arthur Eric
Abstract:: This study was undertaken to find means of separating the morphologically similar species of North American Trixagus and to bring together information on Trixagus and Pactopus. A key to separate the world's eight genera of extant Throscidae is presented for the first time. A key to the five species of...

Nearctic sawflies I, the adults and larvae of the subfamily Blennocampinae (Hymenoptera: Tenthredinidae)

Creator:: Smith, David R.
Abstract:: Seventy-two species of Blennocampinae in 21 genera and six tribes are known from the Nearctic region. The adults and known larvae of all species and genera are keyed, described and illistrated. A definition of the subfamily, a review of previous work, a table of host-plant associations, and a discussion of...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

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...

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...
