Abstract
The soybean cyst nematode, Heterodera glycines Ichinohe, is considered the most damaging pathogen of soybean (Glycine max (L.) Merr.) in the United States and Canada (6). This nematode also causes considerable yield loss in many other soybeanproducing countries in the world. Heterodera glycines was first discovered in the United States in New Hanover County, North Carolina in 1954 (5) and is believed to have been introduced from Asia (3). In 1987, the nematode was discovered in Kent County, Ontario (1). At various times since these initial discoveries, maps were created of the counties in the United States and Canada that were known to be infested with the nematode.
