Various populations presumed to be Empoasca fabae were collected from various host plants and locations in the USA, and then electrophoretically assayed for 12 enzyme loci. Ecological characteristics of Empoasca fabae, including polyphagy, suggest that non-economic plant species in the landscape may be important to its population ecology. Also, 382 clones were evaluated for resistance to nymphal infestations of, and feeding damage (hopperburn) by, Empoasca fabae empoasca fabae Subject Category: Organism Names see more details (Harris).

Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa. Field experiments were carried out at 2 locations in Minnesota, USA, in 1986 and 1987, to examine the effects and interactions of water stress and Empoasca fabae infection on alfalfa [lucerne, Medicago sativa] yield. There was no evidence of genetic differentiation between populations. Once in 3 years, the density of this pest approached, in one of the vineyards, the action threshold recommended for New York. This paper suggests that the potato leafhopper, E. fabae, is an annual circular migrant across multiple generations.
