Differential transmission of strawberry mottle virus by Chaetosiphon thomas Hille Ris Lambers and Chaetosiphon fragaefolii (Cockerell)

Creator:: Eulensen, Gustav Egon
Abstract:: The transmission of strawberry mottle virus (SMV) to Fragaria vesca L. by Chaetosiphon thomasi and C. fragaefolii was studied to determine differences between the two species. Acquisition, inoculation, and retention phases of transmission were described. In all phases, C. fragaefolii was found to be the more efficient vector. Mean transmission...

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...

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...

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...
