First Paragraph: During the late 1980’s and early 1990’s a tremendous amount of research was conducted on grape leafhoppers and their natural enemies. Most of this research happened in California and New York vineyards, but very little in Washington vineyards. When it came time for me to decide what my master’s research topic would be, my major professor Dr. David James and I decided to examine the effects of natural enemies, especially the parasitic wasp known as Anagrus, on leafhopper populations in Washington vineyards. I will now discuss some of the information we gathered in Washington and relate it to the vineyards here in Lodi.
