The Nearctic leafhoppers of the Sorhoanus complex (Homoptera:Cicadellidae)

Creator:: Tao, Lucia Chia-Yao
Abstract:: The Nearctic leafhoppers placed in the genus Sorhoanus Ribaut by Oman (1949) were found to belong to several genera, some of which are Holarctic in distribution. None is properly placed in Sorhoanus as presently defined. The genera Sorhoanus, Zelenius Emel'yanov, Boreotettix Lindberg, Lebradea Remane, and Acharis Emel'yanov are redefined and...

The leafhopper genus Giprus (Homoptera:Cicadellidae)

Creator:: Sawbridge, Jane Rosamund
Abstract:: Members of the deltocephaline leafhopper genus Giprus Oman live on grasses, primarily in the desert-scrub, chaparral, and marine sand dune communities of western North America. Of 16 known species, 10 are undescribed. Recharacterization of the genus results in exclusion of Laevicephalus incongruus Oman. Differentiation of species is primarily dependent on...

The effects of synthetic juvenile hormone on the leafhopper, Draeculacephala crassicornis

Creator:: Reissig, William Harvey
Abstract:: The effects of synthetic juvenile hormone on the viability of eggs, metamorphosis of nymphs, and mating behavior of males and females in diapause was investigated by treating Draeculacephala crassicornis with ENT 33972a. The viability of eggs was reduced 14% by a small dose (0.001 μg) of synthetic juvenile hormone applied...

Taxonomy and distribution of the leaf-hopper genus Aphrodes Curtis (Homoptera:Cicadellidae) in North America

Creator:: Klein, Terry Allen
Abstract:: The subfamily Aphrodinae is represented in the Nearctic Region by eight species contained in a single tribe, Aphrodini, and genus Aphrodes. The external and internal morphology, biology and ecology of the Nearctic members of the genus Aphrodes were investigated. Distributional evidence indicates that six of the eight species, belonging to...

Photoperiodic control of development in the leafhopper, Agalliopsis abietaria Oman

Creator:: Brown, Robert David
Abstract:: Photoperiod controls the duration of both the fourth and fifth stadia in Agalliopsis abietaria Oman. Development was arrested in the fourth stadium unless short days were given during the second and third instars; a short arrest of development occurred if the short days did not begin until the fourth instar....

Environmental biology of Endria inimica (Say) (Homoptera:Homoptera:Cicadellidae)

Creator:: Gustin, Ralph Donald
Abstract:: The leafhopper vector, Endria inimica (Say), of wheat striate mosaic virus is a bivoltine insect which overwinters as second generation eggs in a state of diapause. Under experimental conditions, egg diapause resulted from rearing females under short days (12L:12D) and diapause was averted by rearing females under long days (15L:9D)....

Biological and morphological studies of the Scaphytopius acutus complex (Homoptera:Cicadellidae)

Creator:: Musgrave, Carol A.
Abstract:: Reinterpretation of the leafhopper tribe Scaphytopiini reveals it to be primarily a New World taxon with only limited representation in the Palearctic, Oriental and possibly Ethiopian regions. Approximately 75 species assigned to three genera are known from the United States and Canada with at least another 75 species representing an...
