Introduced in North America in the 40’s, the apple sawfly, Holocampa testudinea, invaded apple orchards of northeastern North America. From 1994 to 2001, apple sawfly cocoons parasitized by Lathrolestes ensator were imported from Western Europe and released yearly in an unsprayed orchard at Frelighsburg, Quebec, Canada. This orchard served a source orchard for the second step of the program. From 2002 to 2009, the parasite has been successfully disseminated in two locatilies in Quebec and one locality in Ontario. The logistics and implications of that program will be dicussed.
