Leafhopper Association on Apple
Journal of Economic Entomology, 1930A brief report of life history studies and field observations of the leafhoppers in Virginia apple orchards. Serious injury to fruit and foliage has resulted from the feeding of six species. The seasonal abundance of Empoasca fabae, E. maligna, Typhlocyba pomaria, Erythroneura hartii, E. oblique, and E.

THE MANITOBAN FAUNA OF LEAFHOPPERS (HOMOPTERA: CICADELLIDAE): II. THE FAUNA OF MACRO-LEAFHOPPERS
The Canadian Entomologist, 1972AbstractThe macro-leafhoppers (Cicadellidae, exclusive of Typhlocybinae) of Manitoba are recorded with distribution and host records for the province, seasonal occurrence of adults, ecological associations, and recent taxonomic changes. These comprise 240 species, including 95 new provincial records, of which 22 are new Canadian records, and 1 is a new

Recent Work on Leafhopper-Transmitted Viruses
1968Publisher Summary This chapter discusses the recent work on leafhopper-transmitted viruses. Current knowledge of the transmission of viruses by leafhoppers suggests that most of these viruses are sucked from the infected plant cells into the gut by the vectors, infect, and are released from the gut into the blood, are carried to the salivary glands ...

Mastrevirus Transmission by the Insect Vectors, Leafhoppers
Mastreviruses are important pathogens on many crops and they are transmitted in a persistent manner by leafhoppers. For experimental studies on mastreviruses, transmission with leafhoppers remains as an important method for virus inoculation. Here, we describe a protocol for setting up a culture of the leafhopper vector Psammotettix alienus and ...Anders, Kvarnheden +2 more
