Abstract:Liriomyza sativae Blanchard and its associated parasites were monitored during the growing season on untreated fresh market tomatoes in southern California in 1978.Chrysonotomyia (Achrysocharella) punctiventris (Crawford) andChrysocharis parksi Crawford were the predominant larval and larval-pupal parasites, respectively, parasitizing the leafminer. A significant linear relationship was found between the percentage parasitization of viableL. sativae larvae byC. parksi and the number ofL. sativae viable pupae per sampling unit.
