Navel orangeworm, Amyelois transitells (Waler), perhaps the most important pest of almonds in California, has plagued growers for the past 25 years and continues to do so. A renewed quest for effective natural enemies throughout the native range of navel orangeworm, in Texas and Central and South America resulted in discovery of a parasitic wasp, Goniozus legneri Gordh, attacking this insect in southern Uruguay and Argentina, where climatic similarities with California's Central Valley are great.
