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

Insecticide and Acaricide Tests, 1989
Abstract ‘PMR 45’ cantaloupes, planted 12 May at the Arkansas Valley Research Center, Rocky Ford, Colo., were used in the study. Plots were 2 beds (60-inch spacing), 24 ft long, arranged in a randomized complete block design with 4 replications.

Successional leafhopper assemblages: Pattern and process
Ecological Research, 1994Abstract Auchenorrhyncha (leafhopper) faunas of a series of experimental plots of different successional age were recorded by vacuum sampling. There were clear successional trends in the assemblages. The life‐history strategy of the dominant species changed during succession; the mobile and multivoltine or bivoltine species, which ...

Sampling Leafhoppers on Soybean
1980Numerous species of leafhoppers (Homoptera: Cicadellidae) have been recorded in association with soybean in the United States. A survey conducted in Arkansas detected 37 species of leafhoppers (Tugwell et al. 1973). Forty-seven species have been recorded in Illinois based on specimens in the International Reference Collection of Soybean-Associated ...

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.

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
