(Typhlocybinae) have tested positive for the presence of some phytoplasmas, and phytoplasma transmission has been proven for one species. 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. Crops, Fruits & Vegetables; Indigenous Vegetables Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa. Preoviposition acts lasted 3-30 minutes, opposition required about 2 minutes, and postoviposition acts lasted 1-4 minutes before feeding was resumed. 1992). The objectives of this study were to compile a host list, to ascertain taxonomic and ecological patterns within the list, and to determine host utilization in non-crop habitats.

This paper suggests that the potato leafhopper, E. fabae, is an annual circular migrant across multiple generations. Thus, it is important to con tinue evaluating germplasm for po-tential sources of resistance to bacterial wilt. Few signs of damage caused by feeding appear on tree hosts but feeding on grapevine and kiwi fruit causes veinal browning, as well as marginal rolling and burning, symptoms often referred to as scorching (Tavella and Arzone, 1989).

Information about Empoasca fabae diagnosis, including distribution and treatment advice There were fewer potato leafhoppers Empoasca fabae in fields with grass corridors (Rodenhouse et al. Invasive Species Compendium. The general expectation of potato leafhopper populations is for there to be significant levels only once in every five to seven years as this is a migratory pest from the Gulf States whose migration trajectory tends to take it to the east of Manitoba.
